notes
my notes for development, it may be useful sometimes when I forget something, so I try to look for it here if I already done it before.
PHP
empty
I encounted in <input type="number"> that even the field is empty, the empty() is not returning true;
I have found it in Stackoverflow.
$quantity = $_POST['quantity'];
foreach ($quantity as $key => $value) {
if (empty($value)) {
unset($quantity[$key]);
}
}
if(!empty($quantity)){
echo 'not empty';
} else {
echo 'empty';
}
