Multiple Select Menu Variables

brooky

Howdie folks,

I need a multiple select drop down menu as follows:

<form method="get" name="myFood">
<select name="food" size="5" multiple>
<option value="1">Peas</option>
<option value="2">Cabbage</option>
<option value="3">Carrots</option>
</select>
</form>

That results in the get variables like...

?food=1&food=3

I don't know how to pick this up with PHP as each GET variable seems to over wright the previous one.

Change the select to this

<select name="food[]" size="5" multiple="multiple">

and then you can access $GET['food'] as an array, ie

if(isset($_GET['food']) && is_array($_GET['food']))
  for($i=0; $i<count($_GET['food']); $i++)
    echo(($i+1).'. '.$_GET['food'][$i]."<br />\n");

HTH
