Re: Dynamic dropdown lists (select)

After reading the rest of the conversation, I think the best solution is the next thing: First, if I got this correct, you can extract the makes select-element from the mysql using a query? if so, then extract it and host is in a temp variable. The next thing is writing down a js code, that contains an array of models for each make. Personally, I'd use a 2 dimension array, the first dimension for the make id/name and the second for the model id/name. The 2 dimm. array you write with something like > echo '<script type="text/javascript">var whatever = new Array();'; > foreach ($cars as $idx => $car) > echo 'whatever['.$idx.'] = > "'.$car->getName().'";'; > echo '</script>'; as Zoltan said. Then you have just simplefied it to a JS based script, i think this is the best way you will figure out which does NOT contains AJAX, only static JS ;) HTH, Nitsan On 04/04/2008, Nathan Nobbe <quickshiftin@gmail.com> wrote: > > On Fri, Apr 4, 2008 at 1:11 PM, Daniel Brown <parasane@gmail.com> wrote: > > > On Fri, Apr 4, 2008 at 9:33 AM, Ryan Yagatich <ryagatich@pantek.com> > > wrote: > > > Angelo Zanetti wrote: > > > > Hi all, > > > > > > > > I am looking at options for creating a dynamic dropdown list. > > > <snip> > > > > > > > > > > Is there any other idea or thing I can do?
