I am sorry for the stupid question, I realize that what I want to do must be extremely simple, but I can't find my way to do it.
I learned basic programing, mostly front end, and enough php to interact with databases and other basics. I can use jquery, javascrip, ajax, no problem in normal situations. But I am not fluent at all in using object-oriented php and I work on a Yii environment.
I have a contact form on the website I'm working on and it works perfectly sending the data to the database. Now I have to re-create the same form, and use it on a pop up box, but I have no idea how to do the php validation and saving to the database in that situation. I've always used Ajax and I tried it, but apparently you need special synthax with ajax on Yii that I am not familiar with.
So is there any way to have the php validation and saving being performed without ajax, (and without the form submitting that refreshes the page and closes the lightbox)?
