我创建了一个使用标准编辑器的自定义帖子类型插件。同样在页面上，我有一个按钮，可以弹出一个jQuery对话框，其中还包含用创建的tinyMCE编辑器wp_editor. 我想修改工具栏上的按钮列表，但仅限于第二个编辑器（对话框中的编辑器）。下面是我现在得到的：

class MyPlugin {
    function MyPlugin() {
        // AJAX action that instantiates the second editor
        add_action( \'wp_ajax_show_my_editor\', array( &$this, \'show_my_editor\' );

        // enqueue the javascript that displays the editor in a dialog
        add_action( \'admin_enqueue_scripts\', array( &$this, \'admin_enqueue_scripts\' ) );

        /**
         * Things I\'ve tried to get the buttons I don\'t want to go away
         */
        // filter buttons directly
        add_filter( \'mce_buttons\', array( &$this, \'mce_buttons\' ), 10, 2 );
        // filter tinyMCE settings pre-init
        add_filter( \'tiny_mce_before_init\', array( &$this, \'tiny_mce_before_init\' ), 10, 2 );
    }

    /**
     * Enqueues the javascript/css that displays the editor in a dialog
     */
    function admin_enqueue_scripts() {
        wp_enqueue_script( \'editor_dialog_js\', plugins_url( \'js/editor_dialog.js\', __FILE__ ), array( \'jquery\', \'jquery-ui-dialog\' ), false, true );
        wp_enqueue_style( \'jquery_ui_smoothness\', \'http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.7/themes/smoothness/jquery-ui.css\' );
    }

    /**
     * Instantiates a wp_editor instance via AJAX call
     */
    function show_my_editor() {
        wp_editor( \'\', \'myeditor\', array(
            \'media_buttons\' => false,
            \'textarea_rows\' => 5,
            \'teeny\'         => false,
            \'quicktags\'     => true,
            \'tinymce\'       => array(
                \'skin\'                    => \'wp_theme\',
                \'plugins\'                 => \'wordpress, wplink\',
                // setting buttons here should work, but doesn\'t
                \'theme_advanced_buttons1\' => \'bold,italic\',
                \'theme_advanced_buttons2\' => \'\',
                \'theme_advanced_buttons3\' => \'\'
            )
        ));
        exit;
    }

    /**
     * Supposed to filter out buttons I don\'t want
     * Possibly redundant since \'theme_advanced_buttons1\' is set above
     */
    function mce_buttons( $buttons, $editor ) {
        // filter out buttons ONLY for the editor loaded via AJAX
        if ( \'myeditor\' == $editor ) {
            $buttons = array_diff( $buttons, array( \'strikethrough\' /* ...other buttons */ ) );
        }
        return $buttons;
    }

    /**
     * Supposed to filter out buttons I don\'t want
     * Possibly redundant since \'theme_advanced_buttons1\' is set above
     */
    function tiny_mce_before_init( $settings, $editor ) {
        // filter out buttons ONLY for the editor loaded via AJAX
        if ( \'myeditor\' == $editor ) {
            $settings[ \'theme_advanced_buttons1\' ] = \'bold,italic\';
        }
        return $settings;
    }
} // end MyPlugin class

jQuery( document ).ready( function( $ ) {
    $( \'#show_editor_dialog_button\' ).click( function() {
        $.get( ajaxurl, { action: \'show_my_editor\' } )
        .success( function( editor ) {
            $( \'<div></div>\' ).html( editor )
            .dialog({
                modal: true,
                buttons: { \'OK\': function() { $( this ).dialog( \'close\' ); } },
                width: 500
            });
            tinymce.execCommand( \'mceAddControl\', true, \'myeditor\' );
            quicktags( { id: \'myeditor\' } );
        });
    });
});

如果我删除if ( \'myeditor\' == $editor ) 然后，所有编辑器的按钮都会被过滤掉，而不仅仅是我想要的AJAX编辑器，如果我使用print_r( $buttons ) 或print_r( $settings[ \'theme_advanced_buttons1 ] )` 在我的任何一个过滤器中，我都可以看到我的过滤器正在运行，它们只在加载AJAX编辑器时运行，并且我想要过滤掉的按钮似乎被过滤掉了。
