I'm new to WordPress development and any advice would be appreciated! I have been a front-end developer for a while and have always handed off forms I created to a back end guy or gal for them to create the functionality via PHP. My knowledge of PHP is extremely lacking.
Anywho what I'd like to do is take all the info the user checked off or typed etc, and send it... (you know, like forms do) but since I created this custom form that I designed and coded in HTML and CSS, is it too late to apply a plugin? Basically, I'm wondering if since it's all already coded do I have to code the PHP myself or can I pull FUNCTIONALITY ONLY from a form plugin?
