Variables!!!

[rapmonkey]

Hi. I am wondering how I can carry over a variable to the next page. I imagine I could do it with cookies but is there any other way?

Here is what I want to do. At one page the varible $game has a value of 5. When the user clicks a link on that page, how would that same variable and its value carry over to the next page (wherever the link takes them)? 😕

im kinda a noob myself here...but what i have done is just make a form with hidden fields...and put a onClick="submit(this.form)" onto the link that takes them to the next page

Well, its not really a form. On one page, when they click a link, it takes them to a different page and sets the variable $game to a value of 5 (in PHP). Then, later on when a user clicks a link on that page (not part of a form just a direct hyperlink to another PHP page) it carries over the value of $game (5) to the next page, so that the final page can do things based on that variable value. 🙂

ya i here ya...i just put in a form with no submit...like say:
<form action=newpage.php method=post>
<input type=hidden name=game value=$game>
<a href="#" onClick="submit(this.form)">
</form>

its prolly very inefficient..but i had the same problem, and it seems to be workin for me fine now

Still I dont think that would work in my situation. Here are the full details. I have one PHP page (index.php) requiring 2 other PHP pages (menu.php and sidemenu.php). Here is where they are on the page:

-----------------------------Menu.PHP-----------------------------
s
i
d
e
m
e
n -----------Main page contents of index.PHP here---------
u
.
P
H
P

The variable $game is set within index.php. What I want is when the user clicks a hyperlink in the menu.php area, it carries the variable $game over to where the link in menu.php takes them. It just seems there must be some other way that makes more sense.

you can form a querry resonse url on the link like so:

echo "<a href=somehtml.phtml?value=" . $value . "> Some Link</a>";

the value can then be retreived from globals in the new page:

$value = $_POST['value'];

the other way is to use sessions. You should read the manual, but
here's what you do

in the page to send the data

session_start();
//must go before any html is ever sent to the client

//attach the variable to the session

$_SESSION['value']=$value;

and in the page you want to retrieve the value:

session_start();

$value= $_SESSION['value'];

good luck,
