I'm trying to set cookies from a form on page 1 and echo the information to page 2 but page 2 just keeps showing a blank page when i try.

I set the cookies on page1 and then called them on page 2. I expected the information to show on page2 but it did not.When i run the code as a whole on page1 it prints out the information under the form. This is the code when I put it together as a whole on page one it runs normally .

Please refer to PHP manual

setcookie() defines a cookie to be sent along with the rest of the HTTP headers. Like other headers, cookies must be sent before any output from your script (this is a protocol restriction). This requires that you place calls to this function prior to any output, including and tags as well as any whitespace.

https://www.php.net/manual/en/function.setcookie.php

As per I can see you're creating the cookie after the HTML outoput.

This example is working for me:

     <?php 
      if($_SERVER["REQUEST_METHOD"] == "POST") {
        if(isset($_POST["fname"], $_POST["lname"], $_POST["email"], $_POST["dob"], $_POST["password"], $_POST["cpassword"])) {
      $fname = $_POST["fname"];
      $lname = $_POST["lname"];
      $email = $_POST["email"];
      $dob = $_POST["dob"];
      $password = $_POST["password"];
      $cpassword = $_POST["cpassword"];

      setcookie("fname", $fname, time() + (86400 * 30), "/");
      setcookie("lname", $lname, time() + (86400 * 30), "/");
      setcookie("email", $email, time() + (86400 * 30), "/");
      setcookie("dob", $dob, time() + (86400 * 30), "/");

      if(isset($_COOKIE["fname"], $_COOKIE["lname"], $_COOKIE["email"], $_COOKIE["dob"])) {
          $fname = $_COOKIE["fname"];
          $lname = $_COOKIE["lname"];
          $email = $_COOKIE["email"];
          $dob = $_COOKIE["dob"];
          echo "First Name: $fname <br>";
          echo "Last Name: $lname <br>";
          echo "Email: $email <br>";
          echo "Date of Birth: $dob <br>";
      } else {
          echo "Cookies not set";
      }
    }
  

    } else {
    ?>
