目前，我已经成功地在WordPress的TinyMCE编辑器中添加了一行快捷键。问题是，只有管理员才能看到该行，我也需要贡献者和编辑器来查看它。我已经检查了法典中的add\\u action和add\\u filter，我看不到任何指示用户角色或类似角色的特定参数。如何修改此代码，以便所有登录的用户都可以看到新行，而不仅仅是管理员？下面是我用来将行添加到编辑器窗口的代码：

// add shortcode buttons to the tinyMCE editor row 3
function add_button_3() {
   if ( current_user_can(\'edit_posts\') &&  current_user_can(\'edit_pages\') )
   {
     add_filter(\'mce_external_plugins\', \'add_plugin_3\');
     add_filter(\'mce_buttons_3\', \'register_button_3\');
   }
}
//setup array of shortcode buttons to add
function register_button_3($buttons) {
   array_push($buttons, "dropcap", "divider", "quote", "pullquoteleft", "pullquoteright", "boxdark", "boxlight", "togglesimple", "togglebox", "tabs", "signoff", "columns", "smallbuttons", "largebuttons", "lists");  
   return $buttons;
}
//setup array for tinyMCE editor interface
function add_plugin_3($plugin_array) {
   $plugin_array[\'lists\'] = get_template_directory_uri().\'/js/customcodes.js\';
   $plugin_array[\'signoff\'] = get_template_directory_uri().\'/js/customcodes.js\';
   $plugin_array[\'dropcap\'] = get_template_directory_uri().\'/js/customcodes.js\';
   $plugin_array[\'divider\'] = get_template_directory_uri().\'/js/customcodes.js\';
   $plugin_array[\'quote\'] = get_template_directory_uri().\'/js/customcodes.js\';
   $plugin_array[\'pullquoteleft\'] = get_template_directory_uri().\'/js/customcodes.js\';
   $plugin_array[\'pullquoteright\'] = get_template_directory_uri().\'/js/customcodes.js\';
   $plugin_array[\'boxdark\'] = get_template_directory_uri().\'/js/customcodes.js\';
   $plugin_array[\'boxlight\'] = get_template_directory_uri().\'/js/customcodes.js\';
   $plugin_array[\'togglesimple\'] = get_template_directory_uri().\'/js/customcodes.js\';
   $plugin_array[\'togglebox\'] = get_template_directory_uri().\'/js/customcodes.js\';
   $plugin_array[\'tabs\'] = get_template_directory_uri().\'/js/customcodes.js\'; 
   $plugin_array[\'columns\'] = get_template_directory_uri().\'/js/customcodes.js\';
   $plugin_array[\'smallbuttons\'] = get_template_directory_uri().\'/js/customcodes.js\';
   $plugin_array[\'largebuttons\'] = get_template_directory_uri().\'/js/customcodes.js\';
   return $plugin_array;
}
add_action(\'init\', \'add_button_3\'); // add the add_button function to the page init
