Validate text field input against database

Hi @utkarshs

I’m not sure what you mean by testing against the Database. Are you trying to create your own validation before saving the input value to the db table?

Hi @utkarshs

Unfortunately, this requires customization on your end.

Here’s a sample code that validate a specific field on form submission:

function um_custom_validate_english_name( $key, $array, $args ) {
    
    if ( preg_match('/[^A-Za-z0-9]/', $args[$key] ) )  {
        UM()->form()->add_error( $key, __( 'Please use only English letters.', 'ultimate-member' ) );
    }
    // add your custom validation 

}
add_action( 'um_custom_field_validation_english_name', 'um_custom_validate_english_name', 30, 3 );

english_name is the field key. You can change it with your field key. The following line will let you display an error when the field is invalid:
UM()->form()->add_error( $key, __( 'Please use only English letters.', 'ultimate-member' ) );
