3.7 – Fatal error: Cannot access private property WPCF7_Pipes

Hi all,

Wondering if anyone can help me. I’m using a function to dynamically get all of the posts within a custom post type into a Select field in CF7.

Since upgrading to CF7 3.7 the above error presents itself. If I roll back to 3.6 the problem disappears! Here’s my code:

function my_add_game_list_to_contact_form ( $tag, $unused ) {  

	if ( $tag['name'] != 'game-list' )
		return $tag;  

	$args = array ( 'post_type' => 'game',
					'numberposts' => -1,
					'orderby' => 'title',
					'order' => 'ASC',
					'post_status' => 'publish' );
	$game_list = get_posts($args);  

	if ( ! $game_list )
		return $tag;  

	foreach ( $game_list as $single_game ) {
		$tag['raw_values'][] = $single_game->post_title;
		$tag['values'][] = $single_game->post_title;
		$tag['labels'][] = $single_game->post_title;
		$tag['pipes']->pipes[] = array ( 'before' => $single_game->post_title, 'after' => $single_game->post_title);
	}  

	return $tag;
}
add_filter( 'wpcf7_form_tag', 'my_add_game_list_to_contact_form', 10, 2);

Is there a fix I can implement to the above code to make it work with 3.7, or is this a bug in 3.7?

Cheers!

Alex
