Meta Box

Hello,

Thank you for looking at this.

The page (being within an iframe; let's call it "primary" page) with form tries to create PHPSESSID cookie when opened on "secondary" page. As for now it works in Firefox, doesn't work in Chrome (session, when https, should be started with params: 'Secure' => 1 'SameSite' => 'None') and doesn't work in Safari (is blocking third party cookies like this one PHPSESSID by default).

As the form submission relies on this session cookie, I think nothing can be done to override Safari policy here.

Did you test with a non-Ajax form as well?

I can for example add comment to the host site but I cannot submit MBFS form. It just reloads.

By the way, I'm using Metabox All in One and it claims about the missing CSS file:

https://(...)/wp-content/plugins/meta-box-aio/vendor/meta-box/mb-frontend-submission/assets/css/frontend-submission.css?ver=2.0.0

Hello, thank you for taking a look at that.

So far I'm using a workaround to keep MB Builder and validations together.

1. I disabled Ajax for front-end forms
2. I added a filter which modifies existing meta boxes by inserting validation formulas

add_filter( 'rwmb_meta_boxes', 'prefix_meta_boxes_validation_rules', 999 );
/**
 * Add validation rules to existing meta boxes.
 *
 * Filter hook: 'rwmb_meta_boxes'
 *
 * @since 1.0.0
 *
 * @param array $meta_boxes Meta Box plugin's meta boxes.
 */
function prefix_meta_boxes_validation_rules( $meta_boxes ) {

    foreach ( $meta_boxes as $i => $meta_box ) :
        $required = [];
        foreach ( $meta_box['fields'] as $field ) :
            if ( isset( $field['required'] ) && $field['required'] ) :
                $required[] = [ $field['id'] => [ 'required' => 1 ] ];
            endif;
        endforeach;
        if ( ! empty( $required ) ) :
            $meta_boxes[$i]['validation'] = [ 'rules' => $required ];
        endif;
    endforeach;

    return $meta_boxes;
}

Such small while so useful!
Thank you!

I just had clients recently who needed to fill a large number of inputs within multiple blocks across many posts and they didn't want to click edit every single time.

Also, I have some blocks that do not render anything interesting but store important data.

Thank you Anh, there are so few tools that make it easy, that it could be a very valuable feature of your plugin.
