General Guidelines ¶

External Links ¶

To protect the users control panel URL from ending up in web server referrer logs, use the masked_url() function from the Control Panel Class.

$this->EE->cp->masked_url('http://www.google.com');

Will result in:

http://example.com/index.php?URL=http://www.google.com

Internal Links ¶

<?='<a href="'.BASE.AMP.'C=controller_name'.AMP.'M=method_name">link text</a>';?>

Control Panel Constants ¶

BASE - Name of control panel file with the users session id.
AMP - Will render &
AJAX_REQUEST - Returns Boolean TRUE if a request was made via an Ajax Request.
QUERY_MARKER - Renders a query marker (?).
APPPATH - Server path to the system/expressionengine directory.
BASEPATH - Server path to the system/codeigniter directory.
PATH_MOD - Server path to the system/expressionengine/modules directory.
PATH_PI - Server path to the system/expressionengine/plugins directory.
PATH_THIRD - Server path to the system/expressionengine/third_party directory
PATH_JQUERY - Server path to jQuery files at system/expressionengine/javascript/compressed/jquery

Customizing the Control Panel Theme ¶

To modify the default control panel theme, we recommend creating a new theme rather than directly editing default. Create a new theme folder, my_theme for example, and copy the images from the default theme so that you end up with:

themes/cp_themes/my_theme
themes/cp_themes/my_theme/images

For any PHP or CSS files that are not present in your theme, ExpressionEngine will “fall back” and retreive them from default instead. This means that your custom theme need only consist of the PHP and CSS files you have actually modified.

As a security precaution, the default theme’s PHP files are not actually located in themes/cp_themes/default but are instead located within the system folder at system/expressionengine/views. If you would like to override any of those files in your own theme, copy them to your own theme’s directory, making sure that the copied files maintain the same directory structure in your theme as they do in the views directory.

Overriding Control Panel Style ¶

ExpressionEngine attempts to load an override.css stylesheet after all others, allowing for easy customization of styling. For example, if you just want to change the color of some elements, your theme might consist of only one CSS file:

themes/cp_themes/my_theme/css/override.css

This stylesheet will be loaded just prior to the cp_css_end hook.

Design Snippets ¶

The following are basic design snippets that may be used:

Basic Control Panel Layout ¶

<div id="mainContent">
        <div class="contents">
                <div class="heading">
                        <h2 class="edit">Page Title</h2>
                </div>
                <div class="pageContents">
                        // Page Content Goes Here
                </div> <!-- pageContents -->
        </div> <!-- contents -->
</div> <!-- mainContent -->

When designing for the module and extension control panel pages, all third-party markup will be rendered in the pageContents div.

Table-based Layout ¶

The ExpressionEngine Control Panel makes usage of the CodeIgniter HTML Table library. You may load this library in your controller using:

$this->EE->load->library('table');

Two default table styles are defined in the Control Panel Library.

$cp_table_template
$cp_pad_table_template

Example Table-based Layout ¶

The following example is from the Updated Sites Module index.php view file.

<?php
        $this->table->set_template($cp_table_template);
        $this->table->set_heading(
                lang('updated_sites_config_name').'/'.lang('edit'),
                lang('view_pings'),
                lang('updated_sites_config_url'),
                form_checkbox('select_all', 'true', FALSE, 'class="toggle_all" id="select_all"').NBS.lang('delete', 'select_all')
        );

        $base_url = BASE.AMP.'C=addons_modules'.AMP.'M=show_module_cp'.AMP.'module=updated_sites'.AMP;

        foreach($pings as $ping)
        {
                $this->table->add_row(
                        '<a href="'.$base_url.AMP.'method=modify'.AMP.'id='.$ping['id'].'">'.$ping['name'].'</a>',
                        '<a href="'.$base_url.AMP.'method=pings'.AMP.'id='.$ping['id'].'">'.lang('view_pings').'</a>',
                        $ping['url'],
                        form_checkbox($ping['toggle'])
                        );
        }
?>
<?=$this->table->generate();?>

Submit Buttons ¶

Form submit buttons should be constructed with the CodeIgniter Form Helper. Basic implementation is as follows:

<?=form_submit(array('name' => 'submit', 'value' => lang('submit'), 'class' => 'submit'));?>

Note that in order to use the table based layout sample code you must first load the table library in your module’s method.

Tab Menu ¶

<ul class="tab_menu" id="tab_menu_tabs">
        <li class="content_tab<?=($_current_tab == 'forum_board_home') ? ' current': ''?>">
                <a href=""></a>
        </li>
        <?php if ($reduced_nav == FALSE): ?>
        <li class="content_tab<?=($_current_tab == 'forum_management') ? ' current': ''?>">
                <a href="<?=$_id_base.AMP.'method=forum_management'?>"><?=lang('forum_management')?></a>
        </li>
        <li class="content_tab<?=($_current_tab == 'forum_admins') ? ' current': ''?>">
                <a href="<?=$_id_base.AMP.'method=forum_admins'?>"><?=lang('forum_admins')?></a>
        </li>
        <li class="content_tab<?=($_current_tab == 'forum_moderators') ? ' current': ''?>">
                <a href="<?=$_id_base.AMP.'method=forum_moderators'?>"><?=lang('forum_moderators')?></a>
        </li>
        <li class="content_tab">
                <a rel="external" href="<?=$board_forum_url?>"><?=lang('forum_launch')?></a>
        </li>
        <?php endif; ?>
</ul>

<div class="clear_left shun"></div>
<?php endif; ?>

Member Preferences Accordion ¶

The Member Preferences accordion makes use if the jQuery UI Accordion Widget. The basic setup in an addon controller would be:

<?php
function my_cp_function()
{
        $this->EE->load->library('table');
        $this->EE->load->helper('form');

        $this->EE->cp->add_js_script('ui', 'accordion');
        $this->EE->javascript->output('
                        $("#my_accordion").accordion({autoHeight: false,header: "h3"});
                ');

        $this->EE->javascript->compile();
}

And in the view file:

<?=form_open('C=addons_modules'.AMP.'M=show_module_cp'.AMP.'module=my_module',
              array('id'=>'my_accordion'))?>

<?php
        $this->EE->table->set_template($cp_pad_table_template);
        $this->EE->table->template['thead_open'] = '<thead class="visualEscapism">';
?>

<div>
        <h3 class="accordion"><?=lang('accordion_header_1)?></h3>
        <div>
        <?php
                // Add Markup into the table
                echo $this->table->generate();
                // Clear out of the next one
                $this->table->clear();
        ?>
        </div>
        <h3 class="accordion"><?=lang('accordion_header_2)?></h3>
        <div>
        <?php
                // Add Markup into the table
                echo $this->table->generate();
                // Clear out of the next one
                $this->table->clear();
        ?>
        </div>

</div>

Forum Preferences Accordion ¶

Controller Code:

function forum_prefs($is_new = FALSE)
{
        // Preferences Matrix

        $P = array(
                'general'       => array(
                                'board_label'           => array('t', '150'),
                                'board_name'            => array('t', '50'),
                                'board_forum_url'       => array('t', '150'),
                                'board_site_id'         => array('f', '_forum_site_menu'),
                                'board_forum_trigger'   => array('t', '70'),
                                'board_enabled'         => array('r', array('y' => 'yes', 'n' => 'no'))
                ),

                'php'   => array(
                                'board_allow_php'       => array('r', array('y' => 'yes', 'n' => 'no')),
                                'board_php_stage'       => array('r', array('i' => 'input', 'o' => 'output'))
        );

Javascript

$(".editAccordion > div").hide();
        $(".editAccordion > h3").css("cursor", "pointer").addClass("collapsed").parent().addClass("collapsed");

        $(".editAccordion").css("borderTop", $(".editAccordion").css("borderBottom"));

        $(".editAccordion h3").click(function() {
                if ($(this).hasClass("collapsed")) {
                        $(this).siblings().slideDown("fast");
                        $(this).removeClass("collapsed").parent().removeClass("collapsed");
