JavaScript API

Introduction

Client-side API is used in WebMail plugins when it's necessary to have some interface changes, e.g. add another user setting screen, modify menu layout, etc.

Plugin architecture

To invoke client-side API, it's necessary to create 2 directories under data/plugins/plugin-name-here dir, called js and templates. They'll hold JavaScript files and HTML templates, respectively.

Let's assume the plugin is called my-custom-plugin, and the plugin class name is CMyCustomPlugin. We'll create data/plugins/my-custom-plugin/index.php file with the following content:

class_exists('CApi') or die();

class CMyCustomPlugin extends AApiPlugin
{
	/**
	 * @param CApiPluginManager $oPluginManager
	 */
	public function __construct(CApiPluginManager $oPluginManager)
	{
		parent::__construct('1.0', $oPluginManager);
	}

	public function Init()
	{
		parent::Init();

		/* This is where JS files and HTML templates are included */

		$this->AddJsFile('js/include.js');
	}
}

return new CMyCustomPlugin($this);

Including files

Under Init function, the following functions can be used to include JS files and HTML templates:

AddJsFile

Includes JavaScript file. Parameters:

$sJsFileName (string) — relative file path

AddTemplate

Includes HTML template. Parameters:

$sTemplateName (string) — template name for referencing in JS files. Will be prefixed with 'Plugin_'; so if the name is set to MyCustomTemplate, it's referenced as 'Plugin_MyCustomTemplate' in JS files.

$sTemplateFileName (string) — relative file path.

$sLayoutName (string, optional) — layout name this template will be used in. By default, mail template is used.

$sLayoutPosition (string, optional) — layout position this template will be used at. Available positions are are 'Layout-Top', 'Layout-Screens-Top', 'Layout-Screens-Middle' (default), 'Layout-Screens-Bottom', 'Layout-Bottom', Login-Footer.

IncludeTemplate

Include template into existing view model. Parameters:

$sParsedTemplateID (string) — template name we're including this template into. Currently, 'Login_LoginViewModel' is available.

$sParsedPlace (string) — template location this template is placed to.

$sTemplateFileName (string) — relative file path.

Screen	Location
Login_LoginViewModel	Login-Before-Submit-Button Login-Before-Description Login-After-Description.
Mail_ComposeViewModel	Compose-Attach-Buttons
Settings_AccountFoldersViewModel	Account-Folders-After-Buttons
Mail_LayoutSidePane_MessagePaneViewModel	Message-Pane-More-Actions-Menu
Common_HeaderViewModel	Header-Middle
Common_HtmlEditorViewModel	Html-Editor-Buttons

Including images and fonts

You might need to have images or fonts included in your plugin. However, standard security measures disallow accessing files found under the data directory. To work around that restriction, special methods were introduced.

AddFontFile

Includes font file for using it within a plugin. Parameters:

$sFontName (string) — font name.

:$sFontPath (string) — relative filesystem path from plugin directory to font file.

Once you have a font included that way, you can reference it in CSS as follows:

url("?plugins/fonts/plugin_name/font_name")

AddFontFile

Includes font file for using it within a plugin. Parameters:

$sImageName (string) — image name.

$sImagePath (string) — relative filesystem path from plugin directory to image file.

Once you have an image included that way, you can reference it in CSS as follows:

url("?plugins/images/plugin_name/image_name")
