Autoloader
==========
* [Home](help)
There is some initial support to class autoloading in Friendica core.
The autoloader code is in `include/autoloader.php`.
It's derived from composer autoloader code.
Namespaces and Classes are mapped to folders and files in `library/`,
and the map must be updated by hand, because we don't use composer yet.
The mapping is defined by files in `include/autoloader/` folder.
Currently, only HTMLPurifier library is loaded using autoloader.
## A quick introdution to class autoloading
The autoloader it's a way for php to automagically include the file that define a class when the class is first used, without the need to use "require_once" every time.
Once is setup you don't have to use it in any way. You need a class? you use the class.
At his basic is a function passed to the "spl_autoload_register()" function, which receive as argument the class name the script want and is it job to include the correct php file where that class is defined.
The best source for documentation is [php site](http://php.net/manual/en/language.oop5.autoload.php).
One example, based on fictional friendica code.
Let's say you have a php file in "include/" that define a very useful class:
```
file: include/ItemsManager.php
<?php
namespace \Friendica;
class ItemsManager {
public function getAll() { ... }
public function getByID($id) { ... }
}
```
The class "ItemsManager" has been declared in "Friendica" namespace.
Namespaces are useful to keep things separated and avoid names clash (could be that a library you want to use defines a class named "ItemsManager", but as long as is in another namespace, you don't have any problem)
If we were using composer, we had configured it with path where to find the classes of "Friendica" namespace, and then the composer script will generate the autoloader machinery for us.
As we don't use composer, we need check that the autoloader knows the Friendica namespace.
So in "include/autoloader/autoload_psr4.php" there should be something like
```
$vendorDir = dirname(dirname(dirname(__FILE__)))."/library";
$baseDir = dirname($vendorDir);
return array(
"Friendica" => array($baseDir."/include");
);
```
That tells the autoloader code to look for files that defines classes in "Friendica" namespace under "include/" folder. (And btw, that's why the file has the same name as the class it defines.)
*note*: The structure of files in "include/autoloader/" has been copied from the code generated by composer, to ease the work of enable autoloader for external libraries under "library/"
Let's say now that you need to load some items in a view, maybe in a fictional "mod/network.php".
Somewere at the start of the scripts, the autoloader was initialized. In Friendica is done at the top of "boot.php", with "require_once('include/autoloader.php');".
The code will be something like:
```
file: mod/network.php
<?php
function network_content(&$a) {
$itemsmanager = new \Friendica\ItemsManager();
$items = $itemsmanager->getAll();
// pass $items to template
// return result
}
```
That's a quite simple example, but look: no "require()"!
You need to use a class, you use the class and you don't need to do anything more.
Going further: now we have a bunch of "*Manager" classes that cause some code duplication, let's define a BaseManager class, where to move all code in common between all managers:
```
file: include/BaseManager.php
<?php
namespace \Friendica;
class BaseManager {
public function thatFunctionEveryManagerUses() { ... }
}
```
and then let's change the ItemsManager class to use this code
```
file: include/ItemsManager.php
<?php
namespace \Friendica;
class ItemsManager extends BaseManager {
public function getAll() { ... }
public function getByID($id) { ... }
}
```
The autoloader don't mind what you need the class for. You need a class, you get the class.
It works with the "BaseManager" example here, it works when we need to call static methods on a class:
```
file: include/dfrn.php
<?php
namespace \Friendica;
class dfrn {
public static function mail($item, $owner) { ... }
}
```
```
file: mod/mail.php
<?php
mail_post($a){
...
\Friendica\dfrn::mail($item, $owner);
...
}
```
If your code is in same namespace as the class you need, you don't need to prepend it:
```
file: include/delivery.php
<?php
namespace \Friendica;
// this is the same content of current include/delivery.php,
// but has been declared to be in "Friendica" namespace
[...]
switch($contact['network']) {
case NETWORK_DFRN:
if ($mail) {
$item['body'] = ...
$atom = dfrn::mail($item, $owner);
} elseif ($fsuggest) {
$atom = dfrn::fsuggest($item, $owner);
q("DELETE FROM `fsuggest` WHERE `id` = %d LIMIT 1", intval($item['id']));
} elseif ($relocate)
$atom = dfrn::relocate($owner, $uid);
[...]
```
This is real "include/delivery.php" unchanged, but as the code is declared to be in "Friendica" namespace, you don't need to write it when you need to use the "dfrn" class.
But if you want to use classes from another library, you need to use the full namespace, e.g.
```
<?php
namespace \Frienidca;
class Diaspora {
public function md2bbcode() {
$html = \Michelf\MarkdownExtra::defaultTransform($text);
}
}
```
if you use that class in many places of the code and you don't want to write the full path to the class everytime, you can use the "use" php keyword
```
<?php
namespace \Frienidca;
use \Michelf\MarkdownExtra;
class Diaspora {
public function md2bbcode() {
$html = MarkdownExtra::defaultTransform($text);
}
}
```
Note that namespaces are like paths in filesystem, separated by "\", with the first "\" being the global scope.
You can go more deep if you want to, like:
```
<?php
namespace \Friendica\Network;
class DFRN {
}
```
or
```
<?php
namespace \Friendica\DBA;
class MySQL {
}
```
So you can think of namespaces as folders in a unix filesystem, with global scope as the root ("\").

HTML.AllowedElements
TYPE: lookup/null
VERSION: 1.3.0
DEFAULT: NULL
--DESCRIPTION--
<p>
If HTML Purifier's tag set is unsatisfactory for your needs, you
can overload it with your own list of tags to allow. Note that this
method is subtractive: it does its job by taking away from HTML Purifier
usual feature set, so you cannot add a tag that HTML Purifier never
supported in the first place (like embed, form or head). If you
change this, you probably also want to change %HTML.AllowedAttributes.
</p>
<p>
<strong>Warning:</strong> If another directive conflicts with the
elements here, <em>that</em> directive will win and override.

<?php
/**
* Takes a well formed list of tokens and fixes their nesting.
*
* HTML elements dictate which elements are allowed to be their children,
* for example, you can't have a p tag in a span tag. Other elements have
* much more rigorous definitions: tables, for instance, require a specific
* order for their elements. There are also constraints not expressible by
* document type definitions, such as the chameleon nature of ins/del
* tags and global child exclusions.
*
* The first major objective of this strategy is to iterate through all the
* nodes (not tokens) of the list of tokens and determine whether or not
* their children conform to the element's definition. If they do not, the
* child definition may optionally supply an amended list of elements that
* is valid or require that the entire node be deleted (and the previous
* node rescanned).
*
* The second objective is to ensure that explicitly excluded elements of
* an element do not appear in its children. Code that accomplishes this
* task is pervasive through the strategy, though the two are distinct tasks
* and could, theoretically, be seperated (although it's not recommended).
*
* @note Whether or not unrecognized children are silently dropped or
* translated into text depends on the child definitions.
*
* @todo Enable nodes to be bubbled out of the structure.
