Creating & Installing a Plugin in FCKeditor
Writing a plugin
The directory structure for a plugin must always follow the same pattern. The plugin directory must have the same name as the plugin and it must contain a fckplugin.js file. It may also optionally include a language directory with various localized language definitions for your Users Interface (UI). Each file defines a single language, and the filenames (without .js) are what should be passed to FCKConfig.Plugins.Add. If your command has no UI then you don't need to supply any language files.
For the 'findreplace' plugin the structure would look like this (assuming the default plugin path is editor/plugins/):
/editor/plugins/findreplace/fckplugin.js /editor/plugins/findreplace/lang/en.js /editor/plugins/findreplace/lang/it.js
The fckplugin.js file defines your plugin. It should register the command(s) that it implements, and create a toolbar button for each one.
// Register the related commands. FCKCommands.RegisterCommand( 'My_Find' , new FCKDialogCommand( FCKLang['DlgMyFindTitle'] , FCKLang['DlgMyFindTitle'] , FCKConfig.PluginsPath + 'findreplace/find.html' , 340, 170 ) ) ; FCKCommands.RegisterCommand( 'My_Replace' , new FCKDialogCommand( FCKLang['DlgMyReplaceTitle'], FCKLang['DlgMyReplaceTitle'] , FCKConfig.PluginsPath + 'findreplace/replace.html', 340, 200 ) ) ; // Create the "Find" toolbar button. var oFindItem = new FCKToolbarButton( 'My_Find', FCKLang['DlgMyFindTitle'] ) ; oFindItem.IconPath = FCKConfig.PluginsPath + 'findreplace/find.gif' ; FCKToolbarItems.RegisterItem( 'My_Find', oFindItem ) ; // 'My_Find' is the name used in the Toolbar config. // Create the "Replace" toolbar button. var oReplaceItem = new FCKToolbarButton( 'My_Replace', FCKLang['DlgMyReplaceTitle'] ) ; oReplaceItem.IconPath = FCKConfig.PluginsPath + 'findreplace/replace.gif' ; FCKToolbarItems.RegisterItem( 'My_Replace', oReplaceItem ) ; // 'My_Replace' is the name used in the Toolbar config.
Installing and adding plugin
Installing
To install a new plugin, copy the unzipped plugin to your editor's plugin directory 'editor/plugins' (e.g. for the placeholder plugin the path to its fckplugin.js file would be 'editor/plugins/placeholder/fckplugin.js'). That's all!
Adding
You can then add the plugin in your custom Configuration File. You can either change the default path, and add it, or use the third paramter to FCKConfig.Plugins.Add to specify the path to the plugin:
// Change the default plugin path. FCKConfig.PluginsPath = FCKConfig.BasePath.substr(0, FCKConfig.BasePath.length - 7) + '_samples/_plugins/' ; // Add our plugin to the plugins list. // FCKConfig.Plugins.Add( pluginName, availableLanguages ) // pluginName: The plugin name. The plugin directory must match this name. // availableLanguages: a list of available language files for the plugin (separated by a comma). FCKConfig.Plugins.Add( 'findreplace', 'en,it,fr' ) ; FCKConfig.Plugins.Add( 'samples' ) // If you want to use plugins found on other directories, just use the third parameter. var sOtherPluginPath = FCKConfig.BasePath.substr(0, FCKConfig.BasePath.length - 7) + 'editor/plugins/' ; FCKConfig.Plugins.Add( 'placeholder', 'en,it,de,fr', sOtherPluginPath ) ; FCKConfig.Plugins.Add( 'tablecommands', null, sOtherPluginPath ) ; FCKConfig.Plugins.Add( 'simplecommands', null, sOtherPluginPath ) ;
Plugins Recipes
Here you can find additional configuration methods which allow you to customize the plugins more properly:
- Establishing a button in the toolbar
- Example on how to access the editor from a popup window
- Example on how to associate a context menu (right click menu) option
Additional information
You can download plugins from Sourceforge Plugins Page. Instructions sometimes are included with the plugin. Otherwise you can try the common instructions just described.
There are a few nice examples on the actual creation of a plugin which include interaction with the editor:
- Dialog based (new window opens) http://sourceforge.net/forum/forum.php?thread_id=1268047&forum_id=257180.
- Selection based (select then click the button) http://sourceforge.net/forum/message.php?msg_id=3091867
