Working with $form object and $entry object

var_dump and print_r will both work. How are you using them? I usually use print_r($entry) or print_r($form) in a gform_after_submission hook, to see what they contain. I normally write that information to a log file and then check that.

I've never gotten that complex. I just do this, which works for me:

<?php
// this will work for form 150
add_action('gform_after_submission_150', 'dump_variables', 10, 2);
// generic logging function
function dump_variables($entry, $form) {
    $logfile = '/var/www/htdocs/gravity/gravity_log.txt';
    $fh = fopen($logfile, 'a');
    $ebody  = "FORM:\n" . print_r($form, TRUE);
    $ebody .= "\n\nENTRY:\n" . print_r($entry, TRUE);
    $ebody .= "\n\nPOST:\n" . print_r($_POST, TRUE);
    fwrite($fh, $ebody);
    fclose($fh);
}

I called it $ebody at one point because I was emailing the data to myself. I just log it now.

Let us know if you need help. It was some quick and dirty rudimentary logging I set up a couple times, but it seems to work OK for debugging and getting at the exact format of the $form and $entry objects.
