Re: Dynamic dropdown lists (select)

Angelo Zanetti írta:

Hi all, I am looking at options for creating a dynamic dropdown list. Ok here is the scenario: All values in the dropdown list (select/option field) are coming from the database. So there will be 2 dropdown lists. First one say gets (for example) a list of cars, Then once the car is choosen the second list is populated with the list of models for the car choosen. I would like to know if its possible to do this without posting as well as without the use of JS. I have seen js examples where the values are all stored in arrays.

without JS it is not possible, unless you put a submit button next to the first select

This is not desireable as I will be getting the values from the the DB using PHP, unless I can write the JS values to the arrays using PHP? Also not sure of that.

sure you can generate the JS arrays with php. just echo out the necessary js, like: echo '<script type="text/javascript">var whatever = new Array();'; foreach ($cars as $idx => $car) echo 'whatever['.$idx.'] = "'.$car->getName().'";'; echo '</script>';

Is there any other idea or thing I can do? Im thinking maybe AJAX but this is for a mobile site (WAP/xHTML) site and Im not sure if the functionality will work on these devices.

I would go for ajax, if possible, but I don't know if it works on wap or not greets, Zoltán Németh

Please advise. Thanks in advance Angelo Web: http://www.elemental.co.za
