Update 4.8.1 invalid callbacks

That’s what i’m getting. Been having an issue with the plugin for the last few hours.

Are you also having issues with an error page opening up after you update/save anything?

I’m getting the invalid callbacks on the error page, plus:

Warning: Cannot modify header information – headers already sent by (output started at /home/content/p3pnexwpnas13_data03/40/3053440/html/wp-content/plugins/meta-box/inc/meta-box.php:353) in /home/content/p3pnexwpnas13_data03/40/3053440/html/wp-includes/pluggable.php on line 1228

I am getting the same warning messages as tburnes (same line numbers and all). I turned off the plugin and a “fatal error” message popped up on my site, so I reactivated the plugin — but I’m not sure what it’s doing to my site, other than worrying me on the back-end. Hopefully the developer is resolving?

Is the plugin installed as normal or are you loading it in another plugin or theme?

Please update the Group extension to the latest version 1.0.5 to fix the bug.

Thanks.

I bought and upgraded the Meta-Box Group extension and I’m still getting the invalid callbacks on the WP Dashboard. On page/post update I’m getting the following on an error page:

Warning: call_user_func() expects parameter 1 to be a valid callback, class ‘RWMB__Field’ not found in /home/content/p3pnexwpnas13_data03/40/3053440/html/wp-content/plugins/meta-box/inc/meta-box.php on line 353

It looks like that upgrade created more errors than I had previously. The plugin is installed as normal, not through another theme or plugin. Any thoughts?

Here is something thatI found that may not be working. After updating to V4.8.0 and V4.8.1 of the plugin, and updating the group version to 1.0.5, I’m still having the issues. After looking into https://metabox.io/steps-fix-problems-meta-box-4-8-0/ and then looking at this https://metabox.io/docs/registering-meta-boxes/, in your doc on registering meta boxes, the id in the array calls for:

'id' => $prefix . 'fname',

When registering Meta Boxes in my code, I’ve got:

'id' => "{$prefix}banner_text",

When showing the content on the front end, I’m using this:

<?php if (rwmb_meta('orion_2016_banner_text') != '') {
				echo '<h1>';
				echo rwmb_meta('orion_2016_banner_text');
				echo '</h1>';
			} else {
	  		 	 the_title( '<h1 class="entry-title">', '</h1>' );
				 } ?>
                 <?php if (rwmb_meta('orion_2016_subhead_text') != '') {
				echo '<h4>';
				echo rwmb_meta('orion_2016_subhead_text');
				echo '</h4>';
			} ?>

Not sure if there is anything in that which would be causing the issue still, but figured it would be worth pointing out the variance.

I’m calling it from my /inc folder as follows:

require get_template_directory() . '/inc/meta-box.php';

Just found the bug. The code to declared messages is put inside fields which makes Meta Box *think* it’s a field ==> invalid:

It should be written like this:

For more info, please check this docs:

I’d love to give you good news that that worked, but now I’m getting this in the dashboard:

expects parameter 1 to be a valid callback, class ‘RWMB__Field’ not found in /home/content/p3pnexwpnas13_data03/40/3053440/html/wp-content/plugins/meta-box/inc/meta-box.php on line 353

I added the code you posted:

// TEXTAREA
			array(
				'name' => __( 'Textarea', 'orion-2016' ),
				'desc' => __( 'Textarea description', 'orion-2016' ),
				'id'   => "{$prefix}textarea",
				'type' => 'textarea',
				'cols' => 20,
				'rows' => 3,
			),
			'validation' => array(
				'rules'  => array(
					"{$prefix}password" => array(
						'required' => true,
						'minlength' => 7,
					),
				),

			// optional override of default jquery.validate messages
			'messages' => array(
				"{$prefix}password" => array(
					'required'  => __( 'Password is required', 'orion-2016' ),
					'minlength' => __( 'Password must be at least 7 characters', 'orion-2016' ),
				),
			)
		)
	));

Haven’t been able to upload an image, or even see my image library since the update. Does it make sense to downgrade to a previous version, and if so is there a way to do it that won’t require re-inputting the content?
