This evening I released beta-2 of the upcoming v0.64 release of WordPress Google Forms. This build addresses a problem recently reported on the Support Forum where the responses for checkboxes wasn’t being recorded properly.
I was able to verify this problem using one of my test forms and began looking into it. It turns out, the changes made in v0.63 to allow the plugin to work with later versions of PHP 5.4 breaks the ability to uses checkboxes. This build employs a similar method of submitting parameters to Google that versions prior to v0.63 did.
Handling checkboxes has long been a challenge due to the different ways which Python (used by Google) and PHP (used by WordPress) handle the assignment of checkbox values to a named parameter.
Please download this build and test and let me know if you run into any issues.Google Forms Beta (1982 downloads)
