当我提交按钮时，很多东西都可以正常工作。它将视频文件保存到帖子中，所以标题和视频没问题，除了视频类别和标签外一切正常。

我只有 2 个问题。

1. 我需要将视频描述作为自定义字段。
2. 视频类别未保存。

Answer 1

对于帖子元中的视频描述：

 $postarr = array(
            'post_title'    =>  $post_title,
            'post_content'  =>  $post_title,// set any value here other wise it will stop inserting your post
            'post_type' =>  'post',
            'post_author'   =>  $user_id,
            'post_status'   =>  $post_status,
            'comment_status'    =>  'open'
        );

        $postarr    =   apply_filters( 'awpt_submit_data_args' , $postarr );

        $post_id = wp_insert_post($postarr, true);
        //this will update your post meta 
        update_post_meta( $post_id, 'videoDescrption', $post_content);
        //below line is write to give you the understanding that you need to pass it as a array
        $arrayoftags=$video_tag;
        wp_set_post_terms( $post_id, $arrayoftags);
        //below line is write to give you the understanding that you need to pass it as a array
        $arrayoftags = $video_category;
        wp_set_post_categories( $post_id, $arrayofcategories );

重要提示：

对于 post meta ：请记住，如果您没有 add_meta 功能，它将在您的管理部分中不可见，但您可以在 postmeta 表中检查数据库中的值。

对于标签：标签中必须有数组。我已将注释放在代码上方。

对于类别：类别中必须有数组。我已将注释放在代码上方。

对于帖子内容：帖子内容不能为空，否则它将停止创建您的帖子。

阅读我在代码中提到的每一条评论。

Answer 2

问题出在类别名称属性中，因为它需要数组，所以我将name="category" 更改为name="category[]"，它工作正常我将标签更改为 post_tag，现在它同时保存了标签和类别。

视频描述的问题是一样的，名称属性的错误现在一切正常。
