I am getting an error on Magento on one of my web-forms:

Fatal error: Call to a member function getId() on a non-object in /home/excalibur/public_html/includes/src/VladimirPopov_WebForms_Model_Fields.php on line 577

This is the code:

  • Please add more code lines, I don't see your $result object.

In absence of more code, the odds are good that your $result object is null when you try and call getId() on it.

To fix this use this:

if($result) {
   $resultId = $result->getId();
}

if ($resultId) {
   .......
}

  • Thanks. Just posted more of the code. I attempted to add the piece of code you suggested but now it just hangs and does not submit.

  • Looking over this a little more, there might be a required field in the admin set up of this code that is missing. Has this extension worked for you in the past? The basic problem is that the value $result is not getting set when it calls $result = $this->getData('result'); in the toHtml() method. The why is a little more tricky to figure out.

  • Yeah it has worked for me before. This is an error I am getting from adding and image upload field on the admin to one of my forms.
