General
Batflat is a Polish content management system that is simple, light and fast. It was first released in May 2016. The free version of the application is shared under a license that requires leaving information about the authors and backlinks. Batflat works great when creating small websites such as business identity, portfolios, blogs or home pages. With this documentation you will learn how to install, configure and create your own modules and themes.
Batflat est un système de gestion de contenu polonais simple, léger et rapide. Il a été publié pour la première fois en Mai 2016. La version gratuite est partagée sous license qui requiert The documentation is divided into several sections. The first is for general instructions, the second is for web designers, and the last two are for web developers.
Pré-requis
Les pré-requis système pour Batflat sont modeste, donc tous les serveurs modernes peuvent suffirent.
- Apache 2.2+ with
mod_rewrite - PHP version 5.6+
- Access to SQLite
La configuration PHP doit avoir les extentions suivantes :
- dom
- gd
- mbstring
- pdo
- zip
- cURL
Installation
Premièrement téléchargez la dernière version de Batflat.
Extract all files from the compressed package and then transfer them to the local directory or remote server. In the case of a remote server, connect to it via a (S)FTP client, such as the free FileZilla program. Usually, files should be uploaded to www, htdocs or public_html.
Warning! Make sure the .htaccess file is also on the server. Without it the CMS will not work.
Some servers may require additional permissions chmod 777 for the following directories and files:
- tmp/
- uploads/
- admin/tmp/
- inc/data/
- inc/data/database.sdb
Open your browser and navigate to the address where the Batflat's files are located. You should see a default template with sample content.
To go to the administration panel, add /admin/ at the end of the URL. The initial login and password are "admin". It should be changed right after login for security reasons. We also recommend rename the directory with the administration panel. (you need to then change the constant value in the defines file).
Configuration
CMS can be configured by editing the settings in the administration panel and through the definition file. However, we do not recommend changing the configuration in the file if you are an inexperienced person.
Administration panel
To change the basic configuration in the admin panel, select the Settings tab. You can enter a page name, description or keywords in the meta tags, as well as elsewhere in the default template, such as in the header. You can also change the homepage, default language (separately for the website and the panel), define the footer content, and choose the editor (HTML or WYSIWYG) that will be available when editing subpages and blog posts.
You will change the configuration of the remaining modules in the tabs corresponding to their names.
Defines file
More advanced things you can change in the inc/core/defines.php file, which contains definitions of constant variables.
ADMIN— the directory name that contains the administration panelTHEMES— path to the directory containing the themesMODULES— path to the directory containing the modulesUPLOADS— path to the directory containing the uploaded filesFILE_LOCK— lock the ability to edit files through the administration panelBASIC_MODULES— list of basic modules that can not be removedHTML_BEAUTY— nice HTML formatting after parsingDEV_MODE— developer mode, where PHP errors and notes are displayed
Update
If you want to keep up to date with all the latest news, bug fixes and security issues, you should regularly check for Batflat updates. You can do this in the Settings -> Updates tab. The system will check for a new version of the script and automatically download a new package from our server and update the core files and modules.
In case of complications you can use manual mode. To do this, download the latest version of Batflat, upload it to the main application directory, and then add the &manual parameter to the end of the update's bookmark URL. The CMS should detect a zipped package and when you click on the update button, the process of extracting and overwriting the files will be performed.
Before each update, Batflat creates a backup. You will find it in the script directory, in the backup/ folder. If an update has failed, you can restore it at any time.
Themes
Structure
The structure of themes in Batflat is very simple. Just create a new folder in the themes/ directory and the following files:
index.html— default template for subpagesmanifest.json— theme informationspreview.png— screenshot showing the theme (optional)
Each subpage can use another template, so besides the mentioned file, you can also create another, eg xyz.html. Template selection is available in the admin panel while creating a page. There are no rules about CSS and JS files. There is full freedom.
In the theme folder you can also create your own module views. To do this, you need to create a directory modules/module_name and *.html files with names corresponding to the names of the original views. For example, the view of the contact form should be contained in the following path: themes/theme_name/modules/contact/form.html. Batflat automatically detects a new view and uses it instead of the module default view.
Template tags
CMS uses a simple template system that includes the following tags:
Variables
{$foo} // simple variable
{$foo|e} // HTML escape for variable
{$foo|cut:10} // content of the variable cut to 10 characters
{$foo.bar} // array
Access to the elements of the array is done by a dot character.
Conditions
{if: $foo > 5}
lorem
{elseif: $foo == 5}
ipsum
{else}
dolor
{/if}
Loops
<ul>
{loop: $foo}
<li>{$key}, {$value}, {$counter}</li>
{/loop}
{loop: $foo as $bar}
<li>{$key}, {$bar}, {$counter}</li>
{/loop}
{loop: $foo as $bar => $baz}
<li>{$bar}, {$baz}, {$counter}</li>
{/loop}
</ul>
The loop tag has 3 stages of expansion. The first is an array variable that the template system will break into three variables named $key, $value and $counter, which counts successive iterations starting from zero. The second step allows you to specify the name of the variable that holds the value, and the third is also the name of the index variable.
Include template files
<html>
<body>
{template: header.html}
<main>
<p>Lorem ipsum dolor sit amet.</p>
</main>
{template: footer.html}
</body>
</html>
PHP code
Today`s date: {?= date('Y-m-d') ?}
If you leave the character =, the code will just execute and nothing will display. This allows you, for example, to define new variables within a template:
{? $foo = 5 ?}
Disable parsing
{noparse}Use the {$ contact.form} tag to display contact form.{/noparse}
Any tags inside the noparse expression will remain unchanged.
Comments
{* this is a comment *}
Comments are not visible in the source file after compiling the template.
Languages
{lang: pl_polski}
Witaj świecie!
{/lang}
{lang: en_english}
Hello world!
{/lang}
If you want to customize the template elements for a particular language, use the tags above.
System variables
Batflat, like its modules, provides many variables (usually arrays) that serve to display each page element. Here are the most important ones:
{$settings.pole}— an array element containing the value of the given Batflat settings field{$settings.moduł.pole}— an array element containing the value of the module settings field{$bat.path}— stores the path where the system resides{$bat.lang}— displays currently used language{$bat.notify}— the last notification{$bat.notify.text}- notification text{$bat.notify.type}- message type corresponding to the Bootstrap classes (danger, success){$bat.header}— additional meta tags, JS scripts and CSS style sheets loaded by modules{$bat.footer}— additional JS scripts loaded by modules{$bat.theme}— displays the path to the active theme with the host{$bat.powered}— displays Powered by Batflat with a link to the official site{$navigation.xyz}— displays a list of<li>navigation elements{$page.title}— displays the name of the subpage{$page.content}— displays the contents of the subpage
Example
manifest.json
{
"name": "Example",
"version": "1.0",
"author": "Bruce Wayne",
"email": "contact@waynecorp.com",
"thumb": "preview.png"
}
index.html
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>{$page.title} - {$settings.title}</title>
<meta name="description" content="{$settings.description}">
<meta name="keywords" content="{$settings.keywords}">
<link rel="stylesheet" href="{$bat.theme}/styles.css">
{loop: $bat.header}{$value}{/loop}
</head>
<body>
<nav>
<ul>
{$navigation.main}
</ul>
</nav>
<main>
<h1>{$page.title}</h1>
{$page.content}
</main>
<footer>
{$settings.footer} {$bat.powered}
</footer>
<script src="{$bat.theme}/scripts.js"></script>
{loop: $bat.footer}{$value}{/loop}
</body>
</html>
Modules
Structure
Each module, like the themes, must be in a separate folder created in the inc/modules/ path. Please note that the directory does not contain uppercase and special characters, such as spaces.
Podczas tworzenia modułu należy zastanowić się nad tym, jakiego typu ma być to moduł. Czy ma być konfiguralny w panelu administracyjnym, czy może ma działać wyłącznie po stronie gości odwiedzających stronę? Ze względu na taki podział, w Batflacie wyróżniamy trzy główne pliki modułu:
When creating a module, you need to think about what type of module you want to use. Is it supposed to be configured in the admin panel or is it supposed to work only on the front-end? Due to this division, in Batflat we distinguish three main module files:
Info.php— contains information about the module, such as name, description, author or iconAdmin.php— content of this file will be accessible through the admin panelSite.php— content of this file will be available for visitors of this site
The fourth but optional file is ReadMe.md which should contain additional information for the future user in Markdown, e.g. how to use the module.
If you are planning to write a module that will use HTML, it would be good to make sure the PHP code is separate from the hypertext markup language. To do this, you need to create a directory views inside the module folder. Include any view files in it.
The problem with multilingualism of the module is similar. Just create language files with the ini extension inside the lang directory.
The structure of the module should look something like this:
example/
|-- lang/
| |-- admin/
| | |-- en_english.ini
| | |-- pl_polski.ini
| |-- en_english.ini
| |-- pl_polski.ini
|-- views/
| |-- admin/
| | |-- bar.html
| |-- foo.html
|-- Admin.php
|-- Info.php
|-- Site.php
+-- ReadMe.md
Creating a module
Info file
The most important file for each module. It contains basic information and instructions during installation and uninstallation.
<?php
return [
'name' => 'Example',
'description' => 'Lorem ipsum....',
'author' => 'Robin',
'version' => '1.0',
'compatibility' => '1.3.*', // Compatibility with Batflat version
'icon' => 'bolt',
'pages' => ['Example' => 'example'], // Registration as a page (optional)
'install' => function() use($core) // Install commands
{
// lorem ipsum...
},
'uninstall' => function() use($core) // Uninstall commands
{
// lorem ipsum...
}
];
A list of icons that you can use in this file is available at fontawesome.io. Be sure not to enter the icon name with the fa- prefix.
Registering a module as a page allows you to freely use the routing and select it as a homepage.
Admin file
The contents of this file will be launched in the admin panel.
<?php
namespace Inc\Modules\Example;
use Inc\Core\AdminModule;
class Admin extends AdminModule
{
public function init()
{
// Procedures invoked at module initialization
}
public function navigation()
{
return [
'Foo' => 'foo',
'Bar' => 'bar',
];
}
public function getFoo($parm)
{
return "Foo $parm!";
}
public function postBar()
{
return "Bar!";
}
}
In the navigation method, include array with the subpages of the module. Each page should be assigned a method (without a prefix). Items of this array will be displayed in the administration panel menu.
Methods can also accept arguments that are passed through the URL. For example, after entering the /example/foo/abc address, the getFoo method will return "Foo abc!".
As you can see in the above listing, each method representing the subpage of the module should have a prefix specifying the type of the request. In most cases we will use the getFoo nomenclature, and the postFoo form form submission. If the method supports all types, it should precede the any prefix (for example, anyFoo). This is important because pages without prefix will not be handled. Supported methods are translated by dynamic routing as follows:
getFoo()— as/example/foofor a GET requestgetFoo($parm)— as/example/foo/abcfor a GET requestpostBar()— asexample/barfor POST requests (form submission)anyFoo()— as/example/foofor each request type
Site file
This file is responsible for the portion seen by visitors of the website. If the module is quite large, good practice is to register it as a page and apply routing.
<?php
namespace Inc\Modules\Example;
use Inc\Core\SiteModule
class Site extends SiteModule
{
public function init()
{
$this->_foo();
}
public function routes()
{
$this->route('example', '_mySite');
}
private function _mySite()
{
$page = [
'title' => 'Sample title..',
'desc' => 'Site description',
'content' => 'Lorem ipsum dolor...'
];
$this->setTemplate('index.html');
$this->tpl->set('page', $page);
}
private function _foo()
{
$this->tpl->set('bar', 'Why So Serious?');
}
}
In the above example, a new bar template variable has been created which, by calling the _foo() method in the module initializer, can be used in the theme files as {$bar}. In addition, the routes() method has created a /example subroutine that points to the _mySite() method call. If you go to http://example.com/example, you will call the _mySite() method.
Language files
The module can contain language variables that can be used in classes and views. Language files have a .ini extension and are located in the lang directory of the module.
For example, if you want to add a language file containing English expressions for the administrative part of the Example module, you should create a new file in the inc/modules/example/lang/admin /en_english.ini path.
The content should resemble the following listing:
full_name = "Firstname and surname"
email = "E-mail"
subject = "Subject"
message = "Message"
send = "Send"
send_success = "Mail successfully sent. I will contact you soon."
send_failure = "Unable to send a message. Probably mail() function is disabled on the server."
wrong_email = "Submited e-mail address is incorrect."
empty_inputs = "Fill all required fields to send a message."
antiflood = "You have to wait a while before you will send another message."
Use the $this->lang('subject') construction in the module class and {$lang.example.subject} in view. For a class, we can leave the second parameter of the lang method, which is the name of the module.
Routing
Routing is the process of processing a received request address and deciding what should be run or displayed. It's supposed to call the appropriate method/function based on the URL of the page. You must use routing inside public routes() method.
void route(string $pattern, mixed $callback)
The first parameter of the route method is a regular expression. Some of the expressions have already been defined:
:any— any string:int— integers:str— string that is a slug
The second parameter is a method name or an anonymous function that passes any number of arguments defined in a regular expression.
Example
public function routes()
{
// URL: http://example.com/blog
// - by calling the method inside the module:
$this->route('blog', 'importAllPosts');
// - by calling an anonymous function:
$this->route('blog', function() {
$this->importAllPosts();
});
// URL: http://example.com/blog/2
$this->route('blog/(:int)', function($page) {
$this->importAllPosts($page);
});
// URL: http://example.com/blog/post/lorem-ipsum
$this->route('blog/post/(:str)', function($slug) {
$this->importPost($slug);
});
// URL: http://example.com/blog/post/lorem-ipsum/4
$this->route('blog/post/(:str)/(:int)', function($slug, $page) {
$this->importPost($slug, $page);
});
}
Methods
Modules have special facades that facilitate access to the methods inside the core. This allows you to shorten the calls of $this->core->foo->bar.

Arguments
file— filename with a view inside the module or path to a file outside of itvariables— an array of variable definitions that can be used as tags (optional)
Example
// Compilation of the view inside the module

// Compilation of the view outside the module
$this->draw('../path/to/view.html', ['foo' => 'bar']);
lang
string lang(string $key [, string $module])

// Select the "desc" field from the "blog" module
$this->settings('blog', 'desc'); // $this->core->getSettings('blog', 'desc');
// Set the content of the "desc" field from the "blog" module
$this->settings('blog', 'desc', 'Lorem ipsum...');
setTemplate
void setTemplate(string $file)
Allows you to change the template file on the front. This method works only in the Site class.
Arguments
file— The name of the template file
Example
$this->setTemplate('index.html'); // $this->core->template = 'index.html';
Core
This is the kernel/engine of Batflat, the most important part that is responsible for all its basic tasks. The core contains many definitions of constants, functions, and methods that you can use when writing modules.
Constants
All definitions of constants are described in the first part of this documentation. To use them in a PHP file just call their names. Constants are particularly useful when building URLs and file paths.
Example
echo MODULES.'/contact/view/form.html';
Functions
Batflat has several built-in helper functions that facilitate the creation of modules.
domain
string domain([bool $with_protocol = true])
Returns the domain name with http(s) or without.

with_protocol— it decides whether the address will be returned with or without protocol
Return value
String with the domain name.
Example
echo domain(false);
// Result: example.com
checkEmptyFields
bool checkEmptyFields(array $keys, array $array)
Checks whether the array contains empty elements. It is useful while validating forms.
Arguments
keys— list of array items that the function has to checkarray— source array
Return value
Returns TRUE when at least one item is empty. FALSE when all elements are completed.
Example
if(checkEmptyFields(['name', 'phone', 'email'], $_POST) {
echo 'Fill in all fields!';
}

// [2] =>
// int(4)
// }
echo parseURL(2);
// Result: "bar"
redirect
void redirect(string $url [, array $data = [] ])
Redirect to the specified URL. It allows you to save data from the array to a session. It is useful to memorize unsaved data from forms.
Arguments
url— address to redirectdata— an array that will be passed to the session (optional)
Example
redirect('http://www.example.com/');
// Save the array to session:
redirect('http://www.example.com/', $_POST);

Database
The database used in Batflat is SQLite version 3. For its use CMS uses a simple class that makes it easy to build queries. You do not need to know SQL to be able to operate it.
In addition, we recommend phpLiteAdmin tool for database management. This is a one-file PHP script similar to phpMyAdmin, where you can administer Batflat tables. This will allow you to familiarize yourself with the structure of existing tables.
The database file is located in inc/data/database.sdb.
SELECT
Select multiple records:
// JSON
$rows = $this->core->db('table')->toJson();
// Array
$rows = $this->core->db('table')->select('foo')->select('bar')->toArray();
// Object
$rows = $this->core->db('table')->select(['foo', 'b' => 'bar'])->toObject();
Select a single record:
// JSON
$row = $this->core->db('table')->oneJson();
// Array
$row = $this->core->db('table')->select('foo')->select('bar')->oneArray();
// Object
$row = $this->core->db('table')->select(['foo', 'b' => 'bar'])->oneObject();
WHERE
Select a record with the specified number in the id column:
$row = $this->core->db('table')->oneArray(1);
// or
$row = $this->core->db('table')->oneArray('id', 1);
// or
$row = $this->core->db('table')->where(1)->oneArray();
// or
$row = $this->core->db('table')->where('id', 1)->oneArray();
Complex conditions:
// Fetch rows whose column value 'foo' is GREATER than 4
$rows = $this->core->db('table')->where('foo', '>', 4)->toArray();
// Fetch rows whose column value 'foo' is GREATER than 4 and LOWER than 8
$rows = $this->core->db('table')->where('foo', '>', 4)->where('foo', '<', 8)->toArray();
OR WHERE:
// Fetch rows whose column value 'foo' is EQUAL 4 or 8
$rows = $this->core->db('table')->where('foo', '=', 4)->orWhere('foo', '=', 8)->toArray();
WHERE LIKE:

$rows = $this->core->db('table')->like('foo', '%bar%')->orLike('foo', '%baz%')->toArray();
WHERE NOT LIKE:
// Fetch rows whose column 'foo' DOES NOT CONTAIN the string 'bar' OR 'baz'
$rows = $this->core->db('table')->notLike('foo', '%bar%')->orNotLike('foo', '%baz%')->toArray();
WHERE IN:
// Fetch rows whose column value 'foo' CONTAINS in array [1,2,3] OR [7,8,9]
$rows = $this->core->db('table')->in('foo', [1,2,3])->orIn('foo', [7,8,9])->toArray();
WHERE NOT IN:
// Fetch rows whose column value 'foo' DOES NOT CONTAIN in array [1,2,3] OR [7,8,9]
$rows = $this->core->db('table')->notIn('foo', [1,2,3])->orNotIn('foo', [7,8,9])->toArray();
Grouping conditions:
// Fetch rows those column value 'foo' is 1 or 2 AND status is 1
$rows = $this->core->db('table')->where(function($st) {
$st->where('foo', 1)->orWhere('foo', 2);
})->where('status', 1)->toArray();
Allowed comparison operators: =, >, <, >=, <=, <>, !=.
JOIN
INNER JOIN:
$rows = $this->core->db('table')->join('foo', 'foo.table_id = table.id')->toJson();
LEFT JOIN:

$rows = $this->core->db('table')->orHaving('COUNT(*)', '>', 5)->toArray();
INSERT
The save method can add a new record to the table or update an existing one when it has a condition. When you add a new record, identification number will be returned.
// Add a new record
$id = $this->core->db('table')->save(['name' => 'James Gordon', 'city' => 'Gotham']);
// Return value: ID number of new record
// Update an existing record
$this->core->db('table')->where('age', 50)->save(['name' => 'James Gordon', 'city' => 'Gotham']);
// Return value: TRUE on success or FALSE on failure
UPDATE
Updating records in case of success will return TRUE. Otherwise it will be FALSE.
// Changing one column
$this->core->db('table')->where('city', 'Gotham')->update('name', 'Joker');
// Changing multiple columns
$this->core->db('table')->where('city', 'Gotham')->update(['name' => 'Joker', 'type' => 'Villain']);
SET
$this->core->db('table')->where('age', 65)->set('age', 70)->set('name', 'Alfred Pennyworth')->update();
DELETE
Successful deletion of records returns their number.
// Delete record with `id` equal to 1
$this->core->db('table')->delete(1);
// Deletion of record with condition
$this->core->db('table')->where('age', 20)->delete();
ORDER BY
Ascending order:
$this->core->db('table')->asc('created_at')->toJson();
Descending order:
$this->core->db('table')->desc('created_at')->toJson();
Combine order:
$this->core->db('table')->desc('created_at')->asc('id')->toJson();
GROUP BY
$this->core->db('table')->group('city')->toArray();
OFFSET, LIMIT
// Fetch 5 records starting at tenth
$this->core->db('table')->offset(10)->limit(5)->toJson();
PDO
Not all queries can be created using the above methods (e.g. creating or deleting a table), so you can also write queries using PDO:
$this->core->db()->pdo()->exec("DROP TABLE `example`");
Template system
Operating the template system is easy and is based primarily on two methods. One allows assigning variables, while the other returns the compiled code. In exceptional situations, the other two methods are useful.
set
void set(string $name, mixed $value)
Assigns a value to a variable that can be used in views.
Arguments
name— variable namevalue— variable value
Example
$foo = ['bar', 'baz', 'qux'];
$this->tpl->set('foo', $foo);
draw
string draw(string $file)
Returns a compiled view code that has previously used template system tags.
Arguments
file— file path
Return value
A string, i.e. a compiled view.
Example
$this->tpl->draw(MODULES.'/galleries/view/admin/manage.html');
noParse
string noParse(string $text)
Protects against compiling template system tags.
Arguments
text— string to be left unchanged
Example
$this->tpl->noParse('Place this tag in website template: {$contact.form}');
noParse_array
array noParse_array(array $array)
Protects against compiling template system tags inside the array.
Arguments
array— array to be left unchanged
Example
$this->tpl->noParse_array(['{$no}', '{$changes}']);
Languages
All language files are located in the lang directories inside the modules and under the inc/lang path.
In this last path there are folders corresponding to the language names in the following format: en_english. The first part is the abbreviation of the language and the second is the full name.
Within the directory is the general.ini file, which contains general language variables for the system.
After creating a new language folder, Batflat automatically detects the added language and allows it to be selected in the admin panel. Note that the procedure for creating a new language should be repeated for each module.
