编辑WordPress主题中function.php文件，通过添加部分代码可以让WordPress自带的编辑器增加丰富的编辑功能

编辑function.php文件代码，在末尾添加如下代码：

//增强编辑器开始
function add_editor_buttons($buttons) {
    $buttons[] = 'fontselect';
    $buttons[] = 'fontsizeselect';
    $buttons[] = 'cleanup';
    $buttons[] = 'styleselect';
    $buttons[] = 'hr';
    $buttons[] = 'del';
    $buttons[] = 'sub';
    $buttons[] = 'sup';
    $buttons[] = 'copy';
    $buttons[] = 'paste';
    $buttons[] = 'cut';
    $buttons[] = 'undo';
    $buttons[] = 'image';
    $buttons[] = 'anchor';
    $buttons[] = 'backcolor';
    $buttons[] = 'wp_page';
    $buttons[] = 'charmap';

    return $buttons;
}

//增强编辑器结束
add_filter("mce_buttons_3", "add_editor_buttons");
