I’ve just tried this and it works fine.
You can add this to your functions.php for the plugin
/**
* Modify the post array
**/
function wpufe_change_post_status( $my_post ) {
$my_post[‘post_status’] = ‘pending’;
//want to change the post author?
$my_post[‘post_author’] = 3;
//must return
return $my_post;
}
add_filter( ‘wpuf_add_post_args’, ‘wpufe_change_post_status’ );
In the submit_post function, comment out the line:
var_dump( $_POST );
You should be fine now.
