im not sure if i should post it in php or html. but here it goes.


im trying to do an application with dropdown selection options where one selector depends on the last, two levels this way.

the options are in a mysql datbase so by using php im retrieving the array for each selector, but how can i make the selectors change live depending on which option you choose without refreshing the page?


do i need something else? like javascript or something like that? i know nothing about JS


Thanks for taking your time reading this,

Ajax!
Google Chained Selects + Ajax.

damn, i don't even know what ajax is, is it a complement of JS?

[patchido]

is it difficult?? maybe i could get a template and just populate it with my information? its 3 chained selects what i need

Ajax is quite simple. It stands for Asychronus Javascript and XML.

If you want to go the exceptionally easy route, you can use jQuery. Otherwise you could look up tutorials on YouTube on how to do pure javascript AJAX (which isn't harder than jQuery, it's just got longer variable names, so it looks harder).

maybe this helps finding the best way for me to make it,


what if i want to add more lines of selectables, something like this, when u open the first page you will see this.

/////////////////// /////////////////// //////////////////
choose type - choose food - choose size
////////////////// /////////////////// //////////////////



and there is a dropdown menu to add more lines. so if i add 2 lines ill have.

/////////////////// /////////////////// //////////////////
choose type - choose food - choose size
////////////////// /////////////////// //////////////////

/////////////////// /////////////////// //////////////////
choose type - choose food - choose size
////////////////// /////////////////// //////////////////

/////////////////// /////////////////// //////////////////
choose type - choose food - choose size
////////////////// /////////////////// //////////////////

thanks!

That is also something you would do with Javascript. 

Look into using jQuery.

AJAX vs Jquery? which one is easier for someone who hasn't code any JS?

[Jessica]

jQuery is a javascript library. It makes it easy to do AJAX.

[patchido]

ohh i see, ill look for some tuts on jquery then, any advice on any specific tuts?

 

thanks
