how to store values in one session in a certain condition

Question

**I want to store data from the $_POST to $_SESSION which fits on certain condition when ever user clicks submit button. and i need to send that certified $_Session array to another page. However, my code is not working right. Could somebody help me on this? :( **

'''

session_start();
$errorFound = 0;

function test_input($data)
{
  $data = trim($data); 
  $data = stripslashes($data);
  $data = htmlspecialChars($data);
  return $data;
}

$cleanData_CUST_name = $_POST['cust']['cust[name]'];


if (isset($_POST['submit_booking'])){
    if (empty($_POST["cust[name]"])) {
        $nameErr = "Name is required";
        $errorFound++;
      } else {
            $name = test_input($_POST["cust[name]"]);
            if (!preg_match("/^[a-zA-Z ]*$/", $name)){
                $nameErr = "Only letters and whitespace are allowed.";
                $errorFound++;
       }if($errorFound ==0){
        $_SESSION['CUST'] =  $_POST['cust[name]']; 
       }
}

is your `$_POST` is a multi dimensional array as this: `$cleanData_CUST_name = $_POST['cust']['cust[name]'];` — Rohit Sahu, May 22 '20 at 10:28
oh so if not, $cleanData_CUST_name = $_POST['cust[name]']; this is gonna be correct? — user13595472, May 22 '20 at 10:45
you're checking if `if (empty($_POST["cust[name]"])) {` empty — Rohit Sahu, May 22 '20 at 10:47
yeah if $_POST["cust[name]"] (which is user input name), it will display error. but my session array is still empty :( — user13595472, May 22 '20 at 10:51

if (isset($_POST['submit_booking'])){
if (empty($_POST["cust[name]"])) {
    $nameErr = "Name is required";
    $errorFound++;
  } else {
        $name = test_input($_POST["cust[name]"]);
        if (!preg_match("/^[a-zA-Z ]*$/", $name)){
            $nameErr = "Only letters and whitespace are allowed.";
            $errorFound++;
   }if($errorFound ==0){
    $_SESSION['CUST'] =  $_POST['cust[name]']; 
   }
}
}

you're missing to close a semicolon for if (isset($_POST['submit_booking'])){
