Meta Box

Hi Hazmi, sorry for the delay in replying.

The image_advanced fields loads saved value via ajax request, so it takes a little time. Only when it's loaded, the field inputs are added. So, please don't update the post before it finishes loading (in that case all inputs are not fully added, and updating will make the post lost saved values).

Hello,

The logic should work. There is just a small typo in your code. In the response, the param should be id instead of id:.

However, loading selected posts to show after updating is the next problem. We need to update options parameter to make the field renders properly. So, I added 2 more functions to get the saved data and put them in the options:

Hi Martin,

Sorry for the confusion. The Builder extension is behind some extensions and we're updating it to catch the others. Specifically:

- The validation module has not yet been added to the Builder. You can do that via the Custom Attributes for meta box (via the Settings tab) like this:

It's not intuitive yet. But it should works (you can verify by seeing the exported Code). Here is the guide to work with custom attributes (written for field settings, but also works for meta box settings).

- Regarding "Why could MB Frontend not allow in the visual interface to select post_title and post_excerpt", my first attempt to build the extension is to make it also work with existing meta box in the backend, where post fields already exist. Adding post fields to the form will duplicate them in the backend. So, they must be removed somehow.

Anyway, can you send me an admin account to check why the code doesn't work via contact form?

Thanks,
Anh

Please add the validation rules to the meta box code exported from the Builder extension. Here is the code:

And the code to show form is just:

$form = '[mb_frontend_form id="question" post_fields="title" submit_button="Submit Question" confirmation="Thank you for submitting your question, which will be addressed shortly!"]';
echo do_shortcode( $form );

Hi Martin,

You can add validation rules for post title, just like normal custom fields:

$meta_boxes[] = [
	'title'      => 'Simple form',
	'id'         => 'simple-form',
	'fields'     => [], // Your fields
	'validation' => [
		'rules' => [
			'post_title' => [
				'required'   => true,
				'minlength' => 5,
			],
		],
	],
];

See more validation rules.

I guess we have some misconception about "template". The template that plugin provides is the "text" version of the meta box settings, which is different from the page template that you imagine in the frontend. Am I correct?

Hello,

Yes, you can. Just create different meta boxes for different pages. You might want to use the MB Include Exclude to show specific meta boxes for a specific page. This extension works well with the MB Template extension.
