Gravity Forms is hands down the best contact form plugin for WordPress. Gravity Forms WordPress Plugin allows you to quickly build and design your WordPress forms using the form editor. You just need to select your fields, configure your options, and easily embed forms on your WordPress powered site using the built in tools.
Worse, they don’t have anything on their website community, and mind you it’s not easy to access that info anyway. Only members and those who have provided their licensed key can get access and read those important bits which should be easily available to all IMO. Eveen after providng all that info, I still could not find solution and then i was forced to do soemthign on my own.
here;s what I did and could manage to do Gravity Forms client side validation using jQuery.
First of all, include jQuery library to your head like this:
After you have created and placed your Gravity Form on your blog, get it’s id and it;s submit button id. If it’s your first form, chances are that it’s id is “gform_1” and submit button id is “gform_submit_button_1”. Place following code inside your WordPress blog head tag, although you can add it anywhere in the page:
The above code will call the form validator function where you can put all your logic. Here’s a sample function that will allow you to check different fields, add this into your page anywhere:
With this client side validation using jQuery, you can now control everything and easily create forms in WordPress. There’s no better forum Plugin available for WordPress than Gravity Forms.
Hope that helps.
