[RESOLVED] Mimic JS functionality in PHP?

duckduckgoose

I'm wondering if it's possible to create something in PHP that behaves like the below JavaScript example...

I have two dropdowns, one for size, one for color. Depending upon what size or color is selected, the other dropdown is filtered so that the colors or sizes listed always correspond.

For example, the following T-Shirt is available in the following colors & sizes:

Baby Tee - Red - S, M
Baby Tee - Blue - S, M, L, XL
Baby Tee - Green - XS, L, XL
Baby Tee - Yellow XS, S, M, L, XL
Baby Tee - Orange, S, M, XL

So, if you select "Red" from the color dropdown, the only sizes that the user sees is S, M. If the user selects "L" from the size dropdown, the only colors the user sees is Blue, Green, Yellow. It works fine in JS, but I want to create the same effect using PHP exclusively.

Is it possible to do this? How would I go about something like that?

As the user's selection is happening client-side, it will require some sort of client-side processing. This could be pure JavaScript, or JavaScript requests to a server-side PHP script (a.k.a. "AJAX"). Alternatively, for a purely PHP solution, you would need a sequence of pages: one where you submit the desired color, and the second then providing the choice of sizes.

The JavaScript and AJAX solutions are the most user-friendly, but have the drawback of not working if the client does not support JS or has it disabled. Perhaps with some clever use of the <noscript> tag you could provide both a JS-based method and a pure PHP server-side method?

Thanks for the response.

I understand, I think.

What if I used JavaScript to submit the form upon the initial select? For example, my product page is located at:

www.example.com/product.php?c=Shirts

Can I direct the user to www.example.com/product.php?c=Shirts&s=S

Then build the color select menu based on what's found in the URL?
