Re: [PHP] checking if an array is empty
There are many different states, in which an array would be empty. Can you post the output of a var_dump($array); in that special case you want to check? In general: 1. the variable may not have been set: if (!isset($myarray)) echo 'error'; 2. the variable is set, but ain't an array: if (!isarray($myarray) echo 'error'; 3. the variable is set and is an array, but contains no data: if (array_count($myarray) == 0) echo 'error'; I think the 3rd case could apply to your problem, but only a print_r or var_dump of the $_POST['myarray'] can show this.

Oh, I see. Without seeing your code, the best recommendation I have
is to loop through the array and remove the empty elements, then check
to see if the array is empty, something like this:
if (is_array($array)) {
foreach ($array as $key = $element) {
if ($element == ) {
unset($array[$key]);
}
}
}
if (empty($array)) {
...
}
Sorry if I'm still misunderstanding...
