Meta Box

Hi Sean,

You're using field ID coaching_lesson_summary in the helper function. But the real ID is $prefix . 'coaching_lesson_summary', which is prefix-coaching_lesson_summary. So, your code should be:

$value = rwmb_meta( 'prefix-coaching_lesson_summary' );
echo $value;

Hi Ale, can you var_dump( $image_fields ) to see what values it has?

Hi, thanks for your feedback. I'm checking it now.

Hi Jiro, you're right about the missing user in the update_user_meta call. I've just added that fixed.

Regarding the var_dump, it's not strange as the field registry (where all fields are stored) is structured like this:

object_type
  specific_type
    field 1
    field 2

For posts, object_type is post and specific_type is post type. For terms, it's term and taxonomy. For users, as there's no specific type, we use user and user.

Hi, please change the priority in the add_action from 0 to something greater than 20. Meta Box plugin register fields at priority 20 (to make sure all custom post types and custom taxonomies are available when they also use the init hook with priority 10). So, changing it to a number greater than 20 makes the meta boxes and fields available and you're able to use the helper functions to get the value.

Hi,

I think this can be done with custom JavaScript only. So you need to enqueue your JS file on the page that has the form, then in the code, when the form is being submitted, check if the value of the textarea is a mobile number or email address. If it is, then return false to prevent the submission.

This is a pseudo-code that might give you some idea:

jQuery( function( $ ) {
    $( '.your-form' ).on( 'submit', function() {
        var value = $( '#your-field' ).val();
        if ( checkIfIsMobileNumberOrEmail( value ) ) {
            return false;
        }
    } );
} );

Hi Jiro, please change the code for meta boxes to:

add_action( 'rwmb_meta_boxes', 'prefix_register_meta_boxes' );
function prefix_register_meta_boxes( $meta_boxes ) {
    $meta_boxes[] = array(
        'id' => 'personal',
        'title' => 'Personal Information',
        'type' => 'user', // Specifically for user
        'fields' => array(
            array(
                'name'  => 'test mb for user',
                'desc'  => '',
                'id'    => 'test4',
                'type'  => 'text',
            ),
        )
    );
    return $meta_boxes;
}

Your code has 2 issues:

• The type of the field should not be string, it's text.
• The function doesn't return $meta_boxes.

I've just made a test with Postman and here is the result:

Assume you have this code to register your meta box:

add_filter( 'rwmb_meta_boxes', 'prefix_register_meta_boxes' );
function prefix_register_meta_boxes( $meta_boxes ) {
    $meta_boxes[] = array(
        // Your meta box code goes here
    );
}

Then change it to:

add_action( 'init', function() {
     add_filter( 'rwmb_meta_boxes', 'prefix_register_meta_boxes' );
} );
function prefix_register_meta_boxes( $meta_boxes ) {
    $meta_boxes[] = array(
        // Your meta box code goes here
    );
}
