passing vars to new php doc

eas442

Im a bit new to php syntax so I need to know how to pass a variable from one php page to another when I click a href link....

Then to access both the variables:

$_GET['var']

and

$_GET['var2']

Notice the first variable has a ? before it (following the .php), then after that, all new variables have &

index.php?var=bla&var2=ads&var3=value&var4=had

and so on

i have a question, can you give me an example of what you would pass vars to another page for?

A very simple example is if you have a new user to your site and you want to display their name on each page of the site. You need their name first, so you ask them for their name and then it gets passed onto each page, like so:

Code for page 1:

<html>
<form method="get" action="page2.html">
<input type="text" name="fname"><br>
<input type="text" name="lname"><br>
</html>

Code for page 2:

<?php
echo("Welcome to the site, "  . $_GET['fname'] .  " " . $_GET['lname'] . "!");
?>

well i've done that.. but hmm, would sessions do the same thing as that? lol, cause i dont remember doing that

cgraz

You could do that many different ways; that's just an example of using the url to pass variables. Although why use a session; it'd just complicate things.

For that particular example, most people usually set the method to POST and just access the variable with $_POST['fname'] (but that wouldn't be going through the URL. radon was just giving an example). Sessions are probably the last way I would do something like that, unless you were going to be passing the variable along more pages (such as if the form was a login form)

thanks cgraz - that helped, it's starting to make sense.
