capturing multiple select values?

[Anon]

i have a form with a multiple select box. when it's submitted via POST, i need to capture all of the values if the user has selected more than one. i tried to show all the key | value elements of the POST array, but it's only showing one key for my select - even when i've selected three or four values.

how can i capture all the values? anyone have a function for this? when i change the form submit to GET, i can see duplicate keys, like:

&focus=value1&focus=value2&focus=value3, etc. but they don't how up in the php array.

thanks.

in your HTML you need to name the selectbox with an array (i.e. select_box_name[]) then the values get posted in the array... I think.

yeah. thanks. i figured it out last night.

for anyone else who reads this, you can loop through the select array and place commas between your values for input into a mySQL table:

//$levels is one array from <select name ="levels[]'" MULTIPLE> on my form. same with $focus

$c1 = count($clevels);
$c2 = count($focus);

for ($i = 0, $z = 1; $i < $c1; $i++, $z++)
{
if ($z == 1)
{
$var_clevels = $var_clevels.$clevels[$i];
}
else
{
$var_clevels = $var_clevels.', '.$clevels[$i];
}
}

for ($i = 0, $z = 1; $i < $c2; $i++, $z++)
{
if ($z == 1)
{
$var_focus = $var_focus.$focus[$i];
}
else
{
$var_focus = $var_focus.', '.$focus[$i];
}
}
