dynamic select menus

[ksmatthews]

I want to create 2 select menus - one static (Menu 1) and the other (Menu 2) populated according to the selection made in Menu 1.

Data will will be pulled from a CSV file.

 

Menu 2 will not have any values in it until an option from Menu 1 has been selected. Then, the options available will be limited based on the Item 1 selection.

PHP must be used to read the CSV file and to capture the data (using arrays)

 

I met this problem before and my approach then was to call a function using the onChange event for Menu1 ...

 

<script type = "text/javascript">function update_select(obj){     

  window.location.href="./call_stats_main.php?choice=" + obj.value;}

</script>

 

onchange="update_select(this)

 

This would reload the page passing a parameter to the URL (?choice=)

 

I could then use $_GET['choice'] to capture the selected value and dynamically populate Menu 2 according to this value.

 

It is the onchange event that triggers the population of menu 2.

 

I would like to know IF THERE IS A BETTER WAY, other than using ajax ?
