Meta Box

Hello Rebecca,

I understand that you want to set the post type based on the select field after submitting the frontend submission form. I share with you an example of how to make it work:

1. I have a field group and a simple select field with the options is the CPT slug and label:

[
    'name'              => __( 'Content type', 'your-text-domain' ),
    'id'                => 'content_type',
    'type'              => 'select',
    'options'           => [
        'book' => __( 'Book', 'your-text-domain' ),
        'post' => __( 'Post', 'your-text-domain' ),
        'page' => __( 'Page', 'your-text-domain' ),
    ],
],

2. This field group is added to the frontend form.

3. I use this code to update the post type of the submitted post based on the select:

add_action( 'rwmb_frontend_after_process', function( $config, $post_id ) {
    if ( isset( $_POST['content_type'] ) ) {
        $post_type = $_POST['content_type'];

        $my_post = [
            'ID' => $post_id,
            'post_type' => $post_type

        ];

        wp_update_post( $my_post );
    }
}, 10, 2 );

Hello,

I add your code to the file functions.php in the theme folder, edit a post, add some sample value and save. The value is saved to the database properly, without any issues. Here is the screen record https://imgur.com/pMriFJ1

If it still doesn't work on your site, please share the site admin account by submitting this contact form https://metabox.io/contact/
I will take a look.

Hello Francesco,

Does it work if you use only Meta Box plugins and a WordPress theme? And please edit the post in the admin area to check if the subscriber is the author of the post. Also, let me know which versions of Meta Box plugins are on your site.

Following the documentation https://docs.metabox.io/extensions/mb-frontend-submission/

Hello Oskar,

This issue is still in progress. I will get back to you when it is fixed. Thank you.

Hello Simon,

Currently, the remote validation callback function only supports accessing one field value that you use the validation rule. It doesn't support accessing other field values in the callback function so you won't have value to compare dates like that.
If you want to compare 2 field values on live, you should create some custom Javascript code and validate the field value before saving it.

Hello,

You can create/edit a settings page and create tabs on the settings page. Then create/edit the field group and select the tab on which the field group will show. Please check these screenshots https://imgur.com/a/UVNHHLN
