Question

In index.php, I have created a form and in the action attribute of the form tag I have specified “page2.php”.

page2.php is also a form, (which continues on from index.php) and in the action attribute of the form tage I have specified “page3.php”. I can retrieve what the user entered into the “location” text box, in the form on index.php and display it in page2.php through the method
<?php echo $_GET["location"]; ?>

but, I now also want to display the user location in page3.php, but when I use the above method it does not work. It give me the error: “Undefined index: location”. I take it is because page3.php can not access the fields from index.php, but how do I get this to work?

Thanks in advance

Answer 1

You will need to store the value of $_GET[“location”]; in a hidden field on page2.php within the form that gets submitted to page3.php.

Update Example

page2.php

<form action="page3.php">
    <input type="hidden" value="<?php print $_GET['location']; ?>" name="location_from_page2" />

page3.php

$location = $_GET["location_from_page2"];

What you’re doing here is printing out the contents of location into the value of a hidden field and then you’re reading this hidden field in page3.php

This is one way to do it but you might want to consider looking into the php sessions.
