How to automatically populate input fields and save cookies with PHP?

I'm trying to make a sign-up form, where some fields would be populated (First Name and Last Name) by the email values.

How do I achieve this? And also, I want to make it to save cookies, 2 values. One "accepted", other "declined". "Accepted" cookies would lead users to accepted.php and "Declined" cookies would lead users to declined.php page.

Here is my code:

<?php

///Check for errors and display them 
ini_set('display_errors', 1);
ini_set('display_startup_errors', 1);
error_reporting(E_ALL);
if(isset($_POST['submit'])){
// Fetching variables of the form which travels in URL
$firstname = $_POST['firstname'];
$lastname = $_POST['lastname'];
$title = $_POST['positiontitle'];
$company = $_POST['companyname'];
$comment = $_POST['comment'];
$all = array($firstname, $lastname, $title, $company);
if($firstname !=''&& $lastname !=''&& $title !=''&& $company !='')
{
//  To redirect user to accepted page
header("Location:accepted.php");
}
}
//  To redirect user to declined page
if (isset($_POST['notsubmit'])) {
    header("Location:declined.php");
}
?>

    <input class="lst-name" type="text" name="lastname" value="<?php echo htmlentities($_GET['lastname']);?>">
    <br /><br />
    Position title:<br />
    <input class"pos-title" type="text" name="positiontitle" value="Position Title"/>
    <br /> <br />
    Company name:<br />
    <input class="cmp-name" type="text" name="companyname" value="Company Name"/>
    <br /><br />
    <input id="save-me" type="submit" value="Save me a seat" name="submit">&nbsp;&nbsp;&nbsp;&nbsp;<input id="not-int" type="submit" value="Not interested, thank you" name="notsubmit">
    <br /><br />

You can set cookies with PHP's setcookie() function: http://php.net/manual/en/function.setcookie.php

As for auto-populating the form fields, you could either echo the variables into the form elements manually:

<input type="text" name="something" value="<?php echo $varname; ?>" />

...or you could use this bit of PHP/jQuery I wrote a while back to do it for me automatically.

On the page that processes your posted data set a session var with an input index to your posted data:

$_SESSION['input'] = $_POST;

Then on your page with the form place this in the head of your page...

<?php
//Place in the <head> of your page. Requires jQuery
if($_SESSION['input']) {
    //reject sensitive fields
    $reject = array("password","cc_num");
    foreach($reject as $r) {
        unset($_SESSION['input'][$r]);
    }

    echo '
<script>
$(document).ready(function() {
  var inputs = '.json_encode($_SESSION['input']).';
  $.each(inputs,function(index,value) {
      $("[name="+index+"]").val(value);
  });
});
</script>
';
    unset($_SESSION['input']);
}
?>

Hope that helps you get where you need to be.
