我正在尝试制作一个插件，根据用户填写表单的方式重定向用户。我很难找到我的问题，我已经把它缩小到一个小片段，似乎工作。

function cf7pp_after_send_mail( $contact_form ) {

    global $postid;

    $submission = WPCF7_Submission::get_instance();

    if ( $submission ) {
        $posted_data = $submission->get_posted_data();

        $postid = $posted_data[\'_wpcf7\'];

        $enable = get_post_meta( $postid, "_cf7pp_enable", true);
        $email = get_post_meta( $postid, "_cf7pp_email", true);

        $valuepassed = get_post_meta($post_id, "_cf7pp_text_menu_b", true);

        if ($enable == "1") {
            if ($valuepassed == "1") {
                if ($email == "2") {

                    include_once (\'includes/redirect.php\');

                    exit;

                }
            }
        }
    }
}

如果我更改：

if ($valuepassed == "1") 

至

if ($valuepassed == "0")

行为改为不重定向，这很好，但我想看看传递给$valuepassed的值是什么，因为此时我无法使它像应该的那样动态地运行。我想看看是否发生了完全出乎意料的事情。

function cf7pp_after_send_mail( $contact_form ) {

    global $postid;

    $submission = WPCF7_Submission::get_instance();

    if ( $submission ) {
        $posted_data = $submission->get_posted_data();

        $postid = $posted_data[\'_wpcf7\'];

        $enable = get_post_meta( $postid, "_cf7pp_enable", true);
        $email = get_post_meta( $postid, "_cf7pp_email", true);

        $valuepassed = get_post_meta($post_id, "_cf7pp_text_menu_b", true);

        if ($enable == "1") {
           // if ($valuepassed == "1") {
                if ($email == "2") {
                      die( $valuepassed );
                //    include_once (\'includes/redirect.php\');

                    exit;

                }
           // }
        }
    }
}
