why My $ _POST cannot be called whereas my form method connects

Question

form.php

<form method="POST" target='_blank' action='CF.php' id="cf" name="cf">
    <input type='text' id='test' name='test' value='0' > 
    <button form="cf">Proses</button>

cf.php

if ($_SERVER["REQUEST_METHOD"] == "POST") {
$test = $_POST['test']; 
if (empty($test)) {
    echo "test is empty";
  } else {
    echo $test;
  }
echo "connect";
}else{
    echo "error";
}
?>

result is "test is empty connect"

did I do a little wrong ? or big wrong ? T.T

You have to consider that empty('0') is equal to true. See docs here

You mean `empty('0')` is *true*… – deceze Apr 08 '21 at 05:25
Yes because`'0'` is coerced to `false` – KmoSkillz Apr 08 '21 at 05:32
