Forms and WordPress Nonce

WordPress nonce快把我逼疯了！当我启动插件并删除它时，我遇到了这个问题，但现在我又回来了，仍然不知道该怎么办。

我到处寻找解决办法。我的代码与其他示例相同/相似。我得到一个“未定义索引‘mrlpt\\u client\\u check’”错误。

在基于用户功能检查权限时，我也会遇到与“mrlpt\\U客户端”相同的错误，但这是我创建的自定义帖子类型，所以我不确定为什么这也不起作用？

这是nonce元素所在的代码。include只是在一个自定义元框中包含一个简短的表单，其中有两个输入字段，一个用于电子邮件地址，一个用于电话号码。

我已经尝试将wp\\u nonce\\u字段（）包含在HTML表单include中，但同样的错误也不起作用。

有人能帮忙吗？谢谢

function mrlpt_client_details( $client_post ) {

    // Retrieve saved metadata if it exists
    $mrlpt_clientEmail = get_post_meta( $client_post->ID, \'_mrlpt_client_email\', true );
    $mrlpt_clientPhoneNum = get_post_meta( $client_post->ID, \'_mrlpt_client_phone_num\', true );

    // Create a nonce field for verification
    wp_nonce_field( \'mrlpt_submit_client\', \'mrlpt_client_check\' );

    // Includes the form elements inside the meta box
    require_once( \'includes/mrlpt-client-form.php\' );
}

    if ( defined( \'DOING_AUTOSAVE\' ) && DOING_AUTOSAVE ) {

    }

metabox upload file

我有一个带有上传文件功能的自定义元文件，但问题是，当点击下面的jQuery代码“插入到帖子”时，我无法获得fileurl按钮的值 window.send_to_editor = function(html) { dlink = jQuery(\'button.urlfile\',html).attr(\'title\'); jQuery(\'#download_link\').val(dlink);
