I am writing a module where I need to grab the submission values of a webform

I am using the webform_submission_insert hook found here however when I print out the $submission array using this:

drupal_set_message('<pre>'.print_r($submission).'</pre>', 'warning');

All I get is this:

<pre>1</pre>

It appears to me this hook is not working correctly and is not populating the array. How can I get the submission values?

I am using Webform version 7.x-4.0-alpha6. The webform I created has about 10 different input fields.

  • I am also getting the same results when I downgrade to 7.x-3.18 and use webform conditional 7.x-1.0-beta1. – joshmmo Nov 15 '12 at 16:05

I was printing the array out incorrectly. Using this code to print works:

drupal_set_message(''. print_r($submission, TRUE) .'');
