Question

I have 2 pages. After the user inserts all their info on page 1, they go to page 2. All the inputted information gets correctly stored in $_POST so I can access it in the next page. I can also insert into mysql database just fine no problem. The thing I’m trying to do is to ONLY execute the insert into the database code IF they click the submit button on the second page. I tried doing this:

Page2.php

<script>
$(document).ready(function(e) {
    $("#PaySubmit").click(function() {
        $.ajax({
            url: 'Insert.php'
        });
    });
});
</script>
<input type="submit" name="PaySubmit" id="PaySubmit" value="Continue"/>

Insert.php

try {
    $link = new PDO('mysql:host=****;dbname=****;charset=UTF-8','****','****');
    $first = $_POST["fname"];
    $last = $_POST["lname"];

    $stmt = $link -> prepare("INSERT INTO Conference (`First Name`, `Last Name`) VALUES (:first, :last)");
        $stmt->bindParam(':first', $first);
        $stmt->bindParam(':last', $last);
    $stmt->execute();

} catch(PDOException $e) {
    print "Error!: " . $e->getMessage() . "<br/>";
    die();
}

The problem is, when you click submit on the 2nd page $_POST gets replaced with data from the second page, so I no longer have access to the 1st page’s data. Any ideas on how to go about this?

Answer 1

Store all the values from the first post in the current SESSION.

You can then access them with the $_SESSION global.

Have a look at the serialize function, it might be able to help you a lot. Or json_encode. They are very useful for storing arrays in one variable and retrieving it later.
