i even tried
echo "<pre>";
print_r($formdetails['taglist']);
echo "</pre>";

foreach ($formdetails['taglist'] AS $k => $v)
{
if ($v == $tagtodelete)
{
echo $v . $tagtodelete;
unset($formdetails['taglist'][$tagtodelete]);
}
}
echo "<pre>";
print_r($formdetails['taglist']);
echo "</pre>";
die;

I THINK it should be :


echo "<pre>";
print_r($formdetails['taglist']);
echo "</pre>";

foreach ($formdetails['taglist'] AS $k => $v)
{
if ($v == $tagtodelete)
{
echo $v . $tagtodelete;
unset($formdetails['taglist'][$k]);
}
}
echo "<pre>";
print_r($formdetails['taglist']);
echo "</pre>";
die;

thanks amy, i'll give it a whirl :)

or an array flip will work if you just process the element value.

alternatively for anyone else baffled by this in the future (probably me).

$tagtodelete = urldecode($_POST['tagdelete']);

$formdetails['taglist'] = explode(',', $formdetails['taglist']);

unset($formdetails['taglist'][array_search($tagtodelete, $formdetails['taglist'])]);
$formdetails['taglist'] = implode(',', array_values($formdetails['taglist']));
