I have the following, which is not outputting "OK" in my browser. I assume the concatenation is wrong. I would be grateful for any help. Cheers.
<?php
$x = array("submit","submit1");
foreach ($x as $value){
if ((isset($_POST['$value . "_" . " x"']))){
echo "OK";
}
?>
I want the content of $_POST to be submit_x, submit1_x etc
As requested, print_r($POST) gives in the browser:
OK
Notice: Undefined index: submit1_x in C:\xampp\htdocs\lotto\test1.php on line 18
