在您提到的示例链接中，它假设您使用的是重力表单中内置的后期生成功能。我想，如果您试图在每个表单提交中创建多个post对象，您可能会想绕过这个问题。在gform_after_submission 胡克，我会这样做。。。

// add the new post EVENT
$event_post_args = array(
    \'comment_status\' => \'closed\', // or open
    \'ping_status\' => \'closed\',
    \'post_author\' => 1, // this represents admin by default.
                        // might need to pull user info if is real user

    \'post_title\' => $entry[1] . \' - \' . $entry[2], // note i have no clue
                                                   // what you want here
    \'post_status\' => \'publish\', 
    \'post_type\' => \'event\',                                 
);

// this returns an integer on success, 0 on failure - creates post!
$post_id = wp_insert_post( $event_post_args );

// add more meta values if you need
$event_meta_values = array(
    \'event_address\'     => $entry[3],
    \'event_phone\'       => $entry[4],
    \'event_something\'   => $entry[5],
);

// as long as wp_insert_post didnt fail...
if($post_id > 0){
    foreach($event_meta_values as $key => $value) {
        // add our post meta
        update_post_meta($post_id, $key, $value);
    }
}

// now we just do the same kind of thing for other Post Type
$club_post_args = array(
    ...
    ...
    \'post_title\' => $entry[6],
);

// etc.

您可能还需要在代码中使用一些条件，以确保这些值在尝试对其进行post或post meta之前不为空。

如果你需要更多的解释，请告诉我。
