Reloading a PHP form without using submit button

[raknin]

Hi,

I have a list that I want every time the list is changed I want to change other elemnets in the form automatically without pressing any submit button, for example an update second list. All this will be done with PHP and Javascript.
Is it possible?

Hi,

try to use the onChange-property of the select-element to call the form again. (You can use JavaScript-code to pass variables (e.g. with the selection) to a PHP-script, which then does the changes you want.)
Maybe just using JavaScript might do the job as well.

<form action="select.htm">
  <p>Your ordering:</p>
  <p>
    <select name="Pizza" size="5"
        onchange="alert(this.form.Pizza.options[this.form.Pizza.selectedIndex].value)">
      <option value="P101">Pizza Napoli</option>
      <option value="P102">Pizza Funghi</option>
      <option value="P103">Pizza Mare</option>
      <option value="P104">Pizza Tonno</option>
      <option value="P105">Pizza Mexicana</option>
      <option value="P106">Pizza Regina</option>
      <option value="P107">Pizza de la Casa</option>
      <option value="P108">Pizza Calzone</option>
      <option value="P109">Pizza con tutti</option>
    </select>
  </p>
</form>

Look into AJAX -- it's based off of javascript. I just started learning it, so I won't begin to post any examples, but if you google it, you can find some good tutorials.

Why would you loook into Ajax? Using just plain JavaScript will do what you want, without going to the server.

Sorry, I meant use Ajax if you needed to populate from a database or elsewhere.

I have no idea what or where he needs to populate the second list from, so Ajax might be a perfectly legitimate solution.
