Brackets showing when no value

Hi Bob,
I am not to sure if this is a bug, or a feature or even if there is an on/off switch.

In some of my text inputs I require values brought in from the url (e.g ?pu=blahblahblah) so in the values i my {pu} to catch the values, which works well. Though. if there is no value in {pu} then it displayes the brackets and the text input name.

Can you please advise?

Thank you.
Ben

Hi Ben,

You need to check if there is a value and set a default if there isn't one set. A Custom Code action with PHP like this should do what you need:

<?php
if ( empty($form->data['pu']) ) {
  $form->data['pu'] = '';
}
?>
