Introduction
There are several ways to extend the core functionality of e107. One of those ways is by using so-called "addons". These addons are files which reside in each plugin's folder and allow a plugin to embed itself inside e107's core pages and functions.
The addons can be recognised by their e_xxxxx.php naming format. By simply placing them inside your plugin's folder, they will be auto-detected during installation and integrated into the system.
Please note: If addons are added after plugin installation, you may need to run the "Scan plugin directories" option in Admin Area > Tools > Database.
TIP: The _blank plugin in the e107_plugins folder contains example addons that may be an easy reference for you.

Plugin addons
e_admin.php
TODO: Add example. See social plugin for an example.
e_bb.php
TODO: Add example.
e_comment.php
TODO: Add example. See social plugin for an example.
e_cron.php
This addon allows a plugin to add additional scheduled task options to e107. (see Admin Area > Tools > Scheduled Tasks).
Example:
class plugindir_cron // plugin-folder name + '_cron'
{
function config() // Setup
{
$cron = array();
$cron[] = array(
'name' => "Name of my function", // Displayed in admin area. .
'function' => "myFunction", // Name of the function which is defined below.
'category' => 'mail', // Choose between: mail, user, content, notify, or backup
'description' => "Description of what my function does" // Displayed in admin area.
);
return $cron;
}
public function myFunction()
{
// Do something.
}
}
e_dashboard.php
This addon adds custom plugin information to the dashboard of e107's admin area. The 'latest', 'status' and 'website stats' areas may all contain information from your plugin.
Previously, the e_latest and e_status addons were used separately for this. They have now been incorporated into the e_dashboard addon.
Example:
class plugindir_dashboard // plugin-folder name + '_dashboard'
{
private $title; // dynamic title.
function chart()
{
$config = array();
$config[] = array(
'text' => $this->activity(),
'caption' => $this->title,
);
return $config;
}
/**
* Non-functional example.
*/
function activity()
{
// do something
}
function status() // Status Panel in the admin area
{
$var[0]['icon'] = "<img src='".e_PLUGIN."plugindir/images/blank_16.png' alt='' />";
$var[0]['title'] = "My Title";
$var[0]['url'] = e_PLUGIN_ABS."plugindir/plugin.php";
$var[0]['total'] = 10;
return $var;
}
function latest() // Latest panel in the admin area.
{
$var[0]['icon'] = "<img src='".e_PLUGIN."plugindir/images/blank_16.png' alt='' />";
$var[0]['title'] = "My Title";
$var[0]['url'] = e_PLUGIN_ABS."plugindir/plugin.php";
$var[0]['total'] = 10;
return $var;
}
}
e_emailprint.php
Deprecated!
This addon has been deprecated. Use e_print.php instead.
e_event.php
This addon allows a plugin to easily hook into system events and trigger their own methods and functions using data provided by those events.
class plugindir_event // plugin-folder + '_event'
{
function config()
{
$event = array();
// Hook into a core event, in this case "login".
$event[] = array(
'name' => "login", // when this is triggered...
'function' => "myfunction", // ..run this function (see below).
);
// Hook into a custom plugin event (created by that plugin author)
$event[] = array(
'name' => "pluginfolder_customevent", // hook into a custom plugin event
'function' => "otherfunction", // ..run another function (see below).
);
return $event;
}
function myfunction($data) // the method to run.
{
// var_dump($data);
}
function otherfunction($data) // the method to run.
{
// var_dump($data);
}
}
e_featurebox.php
TODO: Add example.
e_footer.php
This addon allows a plugin to include code in the footer of every page of the site.
TODO: Add example. See "news" plugin folder for an example.

This addon allows a plugin developer to add data to the <head> of every page. This file is loaded in the header of each page of your site. ie. Wherever you see require_once(HEADERF) in a script.
Typically you would use one or all of the following functions within this file: e107::js(), e107::css() or e107::meta()
Warning: Output should never be echoed or printed from this file!
Example:
if(deftrue('USER_AREA')) // prevents inclusion of JS/CSS/meta in the admin area.
{
e107::js('_blank', 'js/blank.js'); // loads e107_plugins/_blank/js/blank.js on every page.
e107::css('_blank', 'css/blank.css'); // loads e107_plugins/_blank/css/blank.css on every page
e107::meta('keywords', 'blank,words'); // sets meta keywords on every page.
}

$tag_regexp = "'(^|,)(".str_replace(",", "|", $tags).")(,|$)'";
$query = "SELECT * FROM `#_blank` WHERE _blank_id != ".$parm['current']." AND _blank_keywords REGEXP ".$tag_regexp." ORDER BY _blank_datestamp DESC LIMIT ".$parm['limit'];
if($sql->gen($query))
{
while($row = $sql->fetch())

);
return $search;
}
/* Compile Database data for output */
function compile($row)
{
preg_match("/([0-9]+)\.(.*)/", $row['blank_nick'], $user);
$res = array();
$res['link'] = e_PLUGIN."blank_menu/_blank.php?".$row['blank_id'].".fs";
$res['pre_title'] = LAN_SEARCH_7;
$res['title'] = $user[2];
$res['summary'] = $row['blank_message'];
$res['detail'] = e107::getParser()->toDate($row['blank_datestamp'], "long");
return $res;
}
/**

The $override property can be used to override existing core/plugin shortcodes. When set to true existing core/plugin shortcodes matching methods below will be overridden.
Example:
class plugindir_shortcodes extends e_shortcode
{
public $override = false; // when set to true, existing core/plugin shortcodes matching methods below will be overridden.
// Example: {PLUGINDIR_CUSTOM} shortcode - available site-wide.
function sc_plugindir_custom($parm = null) // Naming: "sc_" + [plugin-directory] + '_uniquename'

$config = array();
$config['index'] = array(
'regex' => '^_blank/?$', // matched against url, and if true, redirected to 'redirect' below.
'sef' => '_blank', // used by e107::url(); to create a url from the db table.
'redirect' => '{e_PLUGIN}_blank/blank.php', // file-path of what to load when the regex returns true.
);
$config['other'] = array(
'alias' => '_blank', // the below {alias} is substituted with this value. Default alias '_blank', w which can be customized within the admin area.
'regex' => '^{alias}/other/?$', // matched against url, and if true, redirected to 'redirect' below.
'sef' => '{alias}/other/', // used by e107::url(); to create a url from the db table.

* Experimental and subject to change without notice.
* @return mixed
*/
function delete()

$config['user'] = array(
'user_id' => '[primary]',
'user_name' => '[unique]',
'user_loginname' => '[unique]',
'user_email' => '[unique]',
'user_ip' => '',
// etc.
'WHERE' => 'user_id = '.USERID,
'MODE' => 'update'
);
$config['user_extended'] = array(
'WHERE' => 'user_extended_id = '.USERID,
'MODE' => 'delete'
);
return $config;
}
}
// (plugin-folder)_user_form - only required when using custom methods.
class plugindir_user_form extends e_form
{
// user_plugin_(plugin-folder)_(fieldname)
public function user_plugin_plugindir_field3($curVal, $mode, $att = array())
{
$opts = array(1, 2, 3, 4);
