PHP Concepts - page loading
I am very new so please bare with me.
I know how to submit a form with POST and echo a page in php.
I have a feeling that i am missing a general concept though.
Lets say i have a start page where the user selects a brand of car; ford, Chevy etc. I want to load a second page called for example selectedPage.html that has generic items no matter the car selected and then selection specific data as well.
My question is I essentially need a method to get the selection from the first page to the second and load data based on that selection via AJAX or some other method.
Please advise, sorry not sure if this is a JS, php or general question.
Thanks for the help.
