我正在尝试设置一个前端帖子提交表单。我得到一个错误：

Warning: Cannot modify header information - headers already sent by (output started at /home/sadlight/public_html/members/wp-content/themes/default-child/announcement-submit.php:1) in /home/sadlight/public_html/members/wp-includes/pluggable.php on line 876

我试过了this solution, 但是不行。

此外，当我在下面的代码中使用wp\\u重定向时，它会插入两篇文章，而不是一篇。当我移除它时，它只进入一个。任何帮助都会很好！

仅供参考：我正在使用buddypress和默认的buddypress主题。

<?php

    if ( trim( $_POST[\'postTitle\'] ) === \'\' ) {
        $postTitleError = \'Please enter a title.\';
        $hasError = true;
    }
