黄聪：wordpress如何扩展TinyMCE编辑器，添加自定义按钮及功能

Posted 2020-06-13

在functions.php文件里面添加：

add_action( ‘admin_init‘, ‘my_tinymce_button‘ );

function my_tinymce_button() {
     if ( current_user_can( ‘edit_posts‘ ) && current_user_can( ‘edit_pages‘ ) ) {
          add_filter( ‘mce_buttons‘, ‘my_register_tinymce_button‘ );
          add_filter( ‘mce_external_plugins‘, ‘my_add_tinymce_button‘ );
     }
}

function my_register_tinymce_button( $buttons ) {
     array_push( $buttons, "button_eek", "button_green" );
     return $buttons;
}

function my_add_tinymce_button( $plugin_array ) {
     $plugin_array[‘my_button_script‘] = get_bloginfo(‘template_directory‘) . "/editor.js";
     return $plugin_array;
}

 

在你主题文件夹里面创建一个js文件，命名为editor.js

(function() {
     /* Register the buttons */
     tinymce.create(‘tinymce.plugins.MyButtons‘, {
          init : function(ed, url) {
               /**
               * Inserts shortcode content
               */
               ed.addButton( ‘button_eek‘, {
                    text : ‘Insert shortcode‘,
                    title : ‘Insert shortcode‘,
                    onclick : function() {
                         ed.selection.setContent(‘[myshortcode]‘);
                    }
               });
               /**
               * Adds html tag to selected content
               */
               ed.addButton( ‘button_green‘, {
                    text : ‘Add span‘,
                    title : ‘Add span‘,
                    cmd: ‘button_green_cmd‘
               });
               ed.addCommand( ‘button_green_cmd‘, function() {
                    var selected_text = ed.selection.getContent();
                    var return_text = ‘‘;
                    return_text = ‘<h1>‘ + selected_text + ‘</h1>‘;
                    ed.execCommand(‘mceInsertContent‘, 0, return_text);
               });
          },
          createControl : function(n, cm) {
               return null;
          },
     });
     /* Start the buttons */
     tinymce.PluginManager.add( ‘my_button_script‘, tinymce.plugins.MyButtons );
})();

效果如图：
