Meta Box

Hi,

This is a hard question :). I think the filter allows you to change the value of whole group, as the group is the actual field you're filtering. So, $old and $new are arrays (of sub-field values). I guess you're using a cloneable group? If so, then $old and $new are arrays (of clones), each clone is an array of sub-fields.

Let's try with the code below:

add_filter('rwmb_GROUP_ID_value', 'prefix_change_value',10,3);
function prefix_change_value ( $new, $field, $old )
{
    $text_field_id = 'SUB_FIELD_ID';
    foreach ( $new as $k => $clone )
    {
        $new[$k][$text_field_id] = uniqid();
    }
    return $new;
}

Glad to see you figured it out. To echo nothing if the field is empty, you just need to change the code a little bit:

<?php
$field_id = 'twitter-url';
if ( !empty( $settings[$field_id] ) ) {
    echo '<li><a href=" ' . $settings[$field_id] . '"><i class="fa fa-twitter"></i></a></li>';
}
?>

If it comes with the theme, then you don't need to install the extension as a standalone plugin. Just use it 😉

Hi,

Yes, that's possible. Just define the validation rules in YAML format.

Hi mate,

Can you please export that meta box and send it to me via email: [email protected] then I can look into it. Also, can you please create another test meta box with tabs? Is this works with new meta box?

Best regards,

Hi Sinusite,

You can use native file input with file field. It's the default browser file input, which allows us to select files from computer only.

Did you use any of these plugins: Conditional Logic, Show Hide, Include Exclude? Can you please check the conditions to show or hide the meta boxes?
