Smarty

[smartt]

i try to access the values of a multiple select field in php, but that doesn´t work:

my php, which assigns the associative array looks like this:

$sql="SELECT * FROM laender ORDER BY name ASC";
$laenderrs=$conn->select($sql);
$smarty->assign("laenderrs", $laenderrs);


my tpl looks like this:

<select name="laender[]" size="5" multiple>
{foreach from=$laenderrs item=land}
<option value="{$land.id}">{$land.name}</option>
{/foreach}
</select>

the html-output looks normal:

<select name="laender[]" size="5" multiple>
<option value="3">Botswana</option>
<option value="1">Namibia</option>
<option value="2">Südafrika</option>
<option value="4">Zimbabwe</option> </select>

if i try to access $_POST[laender] in a foreach loop like this:

foreach ($_POST[laender] as $key=>$value){
echo "$key, $value";
}

i get the following error:

Warning: Invalid argument supplied for foreach() in d:\htdocs\admin.php on line 29

if i try this without smarty, it works fine...what is wrong?

Worked fine when I tried it but first use $_POST['laender'] because a string not inside quotes will thorw a constant error and also foreach on a normal array just use foreach($array as $value) then the select value field was displayed for me.
