How to pass multiple variables across multiple pages?

Question

My website involves a user submitting data over several pages of forms. I can pass data submitted on one page straight to the next page, but how do I go about sending it to

Answer 1

Use SESSION variable or hidden input field

Answer 2

if you don't want cookies or sessions: use a hidden input field in second page and initialize the variable by posting it like:

page2----

$name=$_POST['name'];  /// from page one

<form method="post" action="page3.php">
 <input type="text" name="req">
 <input type="hidden" name="holdname" value="<? echo "$name"?>"> 
 ////////you can start by making the field visible and see if it holds the value
</form>

page3----

$name=$_POST['holdname'];    ////post the form in page 2
$req=$_POST['req'];    ///// and the other field
echo "$name, Your name was successfully passed through 3 pages";

Answer 3

You can create sessions, and use posts. You could also use $_GET to get variables from the URL.

Remember, if you aren't using prepared statements, make sure you escape all user input...

Answer 4

You could store the data in a cookie on the user's client, which is abstracted into the concept of a session. See PHP session management.

Answer 5

As mentioned by others, saving the data in SESSION is probably your best bet.

Alternatly you could add the data to a hidden field, to post it along:

page2:

 <input type="hidden" name="username" value="<?php echo $name;?>"/>

page3

echo "hello $_POST['username'};

Answer 6

Use sessions:

session_start(); on every page

$_SESSION['name'] = $_POST['name'];

then on page3 you can echo $_SESSION['name']
