    Hi,

    Is it possible to get values from the 'field' data (the post fields) when using the filter 'rwmb_frontend_validate' so i can check what setting/attribute was used?

    apply_filters( 'rwmb_frontend_validate', $validate, $config );

    Like you can when sanitizing a field before saving to the database.

    If no is it possible to get this data somehow in the front end validation?

    thanks

    Nick

    Hello Nick,

    In the example code on the documentation page, we also share a way to get the post field data by using the global variable $_POST
    https://docs.metabox.io/extensions/mb-frontend-submission/#validation

    add_filter( 'rwmb_frontend_validate', function( $validate, $config ) {
    // Check only if you're on the right form.
    if ( 'your-meta-box-id' !== $config['id'] ) {
        return $validate;
    }
    // Check if users have selected files for an image upload field.
    if ( empty( $_POST['image_upload_field'] ) ) {
        $validate = false; // Return false to show an error message.
    }
    return $validate;
}, 10, 2 );

    Please try this on your end and let me know how it goes.

    Hi

    Sorry i must have not been clear enough, when i mentioned the 'field' data, this is the field settings like you can get when sanitizing a field e.g. of $field below. But can this be done in the front end validation? I need to check a form fields attribute value during the front end validation.

    function my_sanitize_money_field( $value, $field, $old_value, $object_id )

    Hello Nick,

    The filter rwmb_frontend_validate doesn't pass the field settings to the callback function. You can use the helper function rwmb_get_field_settings to get the field settings.
    Please follow the documentation https://docs.metabox.io/functions/rwmb-get-field-settings/
