Meta Box

Hello,

I think it is possible. You can create your own custom JS code and listen to the submit button, when the action click is fired, run your own code to validate the field.

Otherwise, you can look for a PHP library or snippets and use the callback function to validate/sanitize the field value.

Hello Laurent,

There are two fields that have the same ID usure. The field ID must be unique, follow the documentation https://docs.metabox.io/field-settings/

Regarding the modele/marque field, please export the field group to a JSON file and share it here. I will take a look. Follow the documentation
https://docs.metabox.io/extensions/meta-box-builder/

Hello,

I use the time() function in the code block but do not save the time to the post content (a field value), the current timestamp displays correctly. Here is the screen record

Can you please share some screenshots of block settings on your site?

Hello,

Please try to remove the wpautop option in your code and recheck this issue

'options' => [
    'wpautop' => true,
],

I removed it and the <p> tags are added properly on my demo site.

Hello,

I see the attribute() function returns the value correctly on my demo site. You can use the WordPress function get_option() as you do or the Meta Box helper function rwbm_meta() to get a settings page value. Refer to the documentation https://docs.metabox.io/extensions/mb-settings-page/#getting-field-value

Hello,

So you can use another query to get the related catalog post from the session post ID. For example:

{% for post in posts %}

    {# get the course catalog post #}
    {% set catalog_args = { post_type: 'course_catalog', relationship: { id: 'catalog-to-session', to: post.ID } } %}
    {% set catalog_posts = mb.get_posts( catalog_args ) %}
    {% for catalog_post in catalog_posts %}
        {# get the catalog post image and other info #}
    {% endfor %}

{% endfor %}

You will need to change the post type and relationship ID with your own, just for example.

Hello Joe,

If you are on the single product page, you can use the function get_the_title() to get the current product title, assign it to a variable and output it in your code. For example:

$current_product_title = get_the_title();
$connected = new WP_Query( [ ] );
