 How to make a field editable only if blank

Hi - I'd like to make a field that can only be edited if there is not a value already in it. This would end up always being editable on the add page and editable on the edit page if there is no value already in it.
Thanks!

Hey Stucco,
I am trying to solve the same problem without success...
Can you post your working example ?
Thank you.

Hi - For mine, it was just adding the following.
'device' is my field - I added the following to Events - Before Display

if($values['device'] != "") {

$xt->assign('device_editcontrol',$values['device']);

}


You may want to do some trim or something before checking if it is empty in case your users are in the habit of saving fields with only whitespace.

Thank you, Stucco
Your code snippet gave me insight.
This worked for me. This snippet hides the TaxCounty field.



if ($values["TaxCounty"] !== '0')

$pageObject->hideField("TaxCounty");


'TaxCounty' is fieldname
below also worked great.



if($values['TaxCounty'] != "0") {

$xt->assign('TaxCounty_editcontrol',$values['TaxCounty']);

}
