Custom validation for unique number

@enkoes

You can try to use the “Unique Metakey value” UM builtin validation.

Thanks for your reply.

I changed the validate from “Numeric value only” to “Unique metakey value” for NRIC number field in my both registration and profile forms. When I tested it by registering new user with one of member’s NRIC no, there wasn’t any error message prompted. Something missing?

Regards.

Something missing?

Yes, UM must test for the UM Mode ie if it’s during Registration or a Profile update.

I have made an UM Bug report about your issue.

@missveronicatv Thanks for your help! Hope it will be fixed in the next plugin update.

You can try this code snippet until fixed by the UM developers.

For the Registration form set Custom Validation of the NRIC Number field
and set Custom Action to: custom_unique_value_NRIC_Number

add_action( "um_custom_field_validation_custom_unique_value_NRIC_Number", 'custom_unique_value_NRIC_Number', 10, 3 );
function custom_unique_value_NRIC_Number( $key, $array, $submitted_data ) {

    if ( $submitted_data[ $key ] != '' ) {

        $args_unique_meta = array(
            'meta_key'      => $key,
            'meta_value'    => $submitted_data[ $key ],
            'compare'       => '=',
        );

        $meta_key_exists = get_users( $args_unique_meta );

        if ( $meta_key_exists ) {
            UM()->form()->add_error( $key , __( 'You must provide a unique value', 'ultimate-member' ) );
        }
    }
}

Install the code snippet into your active theme’s functions.php file
or use the “Code Snippets” plugin.

Thanks a lot. It works perfectly!

I will keep this code running until UM fix the “Unique Metakey value” issue.
