Hi,

Well if you have a select in html form named select_one and the item that is selected has a value of "2" you would access it like this:

GET:

<?php

$var = $_GET["select_one"];

?>

or for POST:

<?php

$var = $_POST["select_one"];

?>

In the above example $var would now equal 2.

<?
print("<select name=Bunny>
<option value=one>One</option>
<option value=two>Two</option>
</select>
?>

whichever one they select will be the value of Bunny.

for example if the select the first one you could say:

if($Bunny)
{
printf("Bunny equals %s", $Bunny);
}

which would print: Bunny equals one

you don't listen very well do you?

<form action="<?=$PHP_SELF?>" method="POST">
<select name="foo">
<option value="bar">bar
</select>
</form>
<?

if (isset($foo) && !empty($foo) {
  echo $foo;
}

?>

I think Elfyn is absolutley correct, but would add that you should be screening the parameters for unwanted php or html tags, length etc.....
