[Resolved] Auto create child post if generic checkbox is checked

I have a post type Maintenance Task that has a one => many relationship with post type Log Item.

I have a CRED form to create Maintenance Tasks. It's got a generic checkbox field on it with slug auto-add-log-item.

What I need to happen: when adding a Maintenance Task, and if the auto-add-log-item checkbox is ticked, I want to add a Log Item as a child.

Here's where my code is at the moment:

function create_child_log_item($post_id, $form_data) {

	if ( $_POST['auto-add-log-item'] != '' ) {

		$parent_id = get_the_ID();

		$log_item = array(
			'post_title' => $title,
			'post_content' => '',
			'post_status' => 'publish',
			'post_type' => 'log-item',
			'meta_input' => array(
			),
		);

		$log_item_id = wp_insert_post( $log_item , $wp_error );

		if ( $form_data["id"]==283 ) {
			toolset_connect_posts( 'maintenance-task-log-item', $parent_id, $log_item_id );
		}

	}

}
add_action("cred_save_data","create_child_log_item",10,2);

However, when submitting the form, I get a 500 error. Any idea why that might be?

It could be because of this line:

$parent_id = get_the_ID();

Delete this line. The function get_the_id won't give you the information you need in this context. Use the $post_id variable instead (from the callback params). Then update your toolset_connect_posts API call:

toolset_connect_posts( 'maintenance-task-log-item', $post_id, $log_item_id );

If that does not resolve the problem, I'll need to take a look at the server logs to get more information about the error. If you're not familiar with server logs, I can show you how to activate them. Go in your wp-config.php file and look for

define('WP_DEBUG', false);

Change it to:

define('WP_DEBUG', true);

Then add these lines, just before it says 'stop editing here':

ini_set('log_errors',TRUE);
ini_set('error_reporting', E_ALL);
ini_set('error_log', dirname(__FILE__) . '/error_log.txt');

Create a new post to trigger the 500 error again. This should create an error_log.txt file in your site's root directory. Please send me its contents. Once that is done, you can revert the changes you made to wp-config.php.

Ahh- thanks. It now works!

I did have to comment out the

if ( $_POST['auto-add-log-item'] != '' ) {

to get it to actually create a Log Item- so that line obviously isn't getting the value of the checkbox. Any idea why that may be?

If it's a Types field, then you must add the wpcf- prefix to your slug:

if ( $_POST['wpcf-auto-add-log-item'] != '' ) {

[davidS-53]

Hmm, doesn't work with or without the prefix. auto-add-log-item is a generic field- does that matter? Is the value not passed through or something?

[Christian Cox]

If it's a generic field, the wpcf- prefix should NOT be used. Sorry for the confusion on that. In the conditional you should test whether or not the key exists. It will not exist if the checkbox is unchecked:

if ( isset( $_POST['auto-add-log-item']  )  ) {

Ahh right- thanks. All working now.
