给wordpress默认编辑器增强添加h1h2h3等常用标签

前面小编讲过怎样增强wordpress默认编辑器，为怎样修改wordpess编辑器中文章内容字体的字号大小今天给大家讲下怎样给wp编辑器添加h1h2h3常用标签，其实方法都是一样的，只是改变了标签的类型说明而已。

wordpress增加h1h2自定义标签办法：找到wp主题的functions.php文件，路径为：/home/wp-content/themes/主题文件夹/functions.php，然后将以下代码添加：

//添加HTML编辑器自定义快捷标签按钮
add_action('after_wp_tiny_mce', 'add_button_mce');
function add_button_mce($mce_settings) {
?>
<script type="text/javascript">
    QTags.addButton( 'hr', 'hr', "n<hr />n", "" );
    QTags.addButton( 'h1', 'h1', "n<h1>", "</h1>n" );
    QTags.addButton( 'h2', 'h2', "n<h2>", "</h2>n" );
    QTags.addButton( 'h3', 'h3', "n<h3>", "</h3>n" );
    QTags.addButton( 'pre', 'pre', "n<pre>n", "n</pre>n" );
</script>
<?php
}

//pre防html转义代码
 // convert htmlentity for pre tag
 add_filter('the_content', 'htmlspecialchars_pre', 12);
 add_filter('get_comment_text', 'htmlspecialchars_pre');
 function htmlspecialchars_pre ($content) {
             return preg_replace_callback ("<pre>(.*?)<\/pre>/si", create_function('$matches','return "<"."pre".">" . htmls_pecial_chars($matches[1]) ."<"."/pre>";'),$content);
 }

 function htmls_pecial_chars($content=''){
        $content = str_replace("<","<",$content);
        $content = str_replace(">",">",$content);
        $content = str_replace("&","&",$content);
        $content = str_replace('"',""",$content);
        $content = str_replace("'","'",$content);
        $content = str_replace(" "," ",$content);
       return $content;
 }
