考虑到WP挂钩的功能，在这里设置额外内容的唯一方法是使用挂钩重新组织回复/编辑表单本身。

下面的示例演示如何在“回复”表单上添加额外的HTML内容。找出代码中的“这是您的自定义内容”标签，以检查魔法发生的地方。

add_filter(\'wp_comment_reply\', \'test_reply_comment_func\', 10, 2);

function test_reply_comment_func($str, $input) {
    extract($input);
    $table_row = TRUE;
    if ($mode == \'single\') {
        $wp_list_table = _get_list_table(\'WP_Post_Comments_List_Table\');
    } else {
        $wp_list_table = _get_list_table(\'WP_Comments_List_Table\');
    }
    // Get editor string
    ob_start();
    $quicktags_settings = array(\'buttons\' => \'strong,em,link,block,del,ins,img,ul,ol,li,code,spell,close\');
    wp_editor(\'\', \'replycontent\', array(\'media_buttons\' => false, \'tinymce\' => false, \'quicktags\' => $quicktags_settings, \'tabindex\' => 104));
    $editorStr = ob_get_contents();
    ob_end_clean();`

        wp_nonce_field("unfiltered-html-comment", "_wp_unfiltered_html_comment", false);

Result

此代码覆盖默认答复表单代码。回复注释和编辑注释内部连接。当您触发“快速编辑”时<div> 属于.addhead 和.edithead 可见，.replyhead - 隐藏的当您触发“回复”时.addhead 和.edithead 是隐藏的，.replyhead - 看得见的
