optgroup and $_POST

niconiko · 08-19-2009, 09:28 AM

I cannot retrieve all the values of an optgroup set to multiple.

When I use the following PHP script, I get only one of the multiply-selected optgroup values:

PHP Code:


			
<?php

foreach (array_keys($_POST) as $key) {

$$key = $_POST[$key];

print "$key is ${$key}<br />";

}

?>

The html form script is:

html Code:

<form name="myform" action="process.php" method="POST">

<div align="center">

<select name="Vote101" multiple="multiple" size="5">

  <optgroup label="Swedish Cars">

    <option value="volvo">Volvo</option>

    <option value="saab">Saab</option>

  </optgroup>

  <optgroup label="German Cars">

    <option value="mercedes">Mercedes</option>

    <option value="audi">Audi</option>

  </optgroup>

</select>

</div>

<br><input type="submit" value="Send"><br>

</form>

What I expect to happen is that, if someone selects "Volvo" and "Audi", then, when rerieving $_POST, I should see both "Volvo" and "Audi". As it is now, the PHP print command is only returning "Audi".

Thank you.
