如何从重力表单条目对象中获取复选框的值？

Question

This seems like it should be a fairly easy question, but Google is not yielding results.

I'm writing a WordPress plugin that processes data from Gravity Forms after the submission is complete. I'm using the gform_after_submission hook.

This passes an "Entry Object" to my function for processing. Most of the values I can extract just fine. So for example:

$eventDate = $e[2];

...Works just fine. This is a date field. All I have to do is pull the value out of the entry object with the proper index.

My issue is getting the value of a particular checkbox. I need to see if it was checked or not.

This doesn't work:

$checkbox = $e[4];

I'm guessing it's because a checkbox field can have multiple values. Unfortunately I'm not sure how to get to the value of each specific checkbox.

Thank you in advance for your help!

Answer 1

If no checkbox value is set manually, the variable will have the value "on". Please do a var_dump($e); and post the result.
