multi-page web applications

[Anon]

I was wondering if anyone knows how to send variables that you're using in one php code to another. I'd like to have a user login, then for whatever page the user goes to the webpage will have a custom greeting.

Are cookies the only way to do that.

Question number 2: Can php link to another php page (like a next button on a form) and send certain important variables? Is there a way to just send all variables to the next php function?

Thanks so much

I'm kinda new at this so someone tell me if I'm wrong 🙂

1. Variables in a form will automatically be passed to the next php page. On the second page just declare the variables you've passed as global. Example:

<form action='loggedin.php'>
Name: <input type='text' name='username'><br>
Pass: <input type='text' name='pass'><br>
<input type='submit' value='Log In'>
</form>

Then on the next page:

global $username, $password;

2. You can definitely link to another page. Example:

$out = "<a href=nextpage.php><img src='next.gif'></a>";

echo $out;

If you want to pass variables that aren't in the form:

$out = "<a href=nextpage.php?username=$username><img src='next.gif'></a>";

echo $out;

I hope this answers your questions!
