Recall/use a variable

[liteon]

How can I recall/use a variable and it content when I am moving to another page?

Example: the integer $s in file 1.php (result of a calculation) will be used/recall with it content in script 2.php, and in 2.php script it will be multiple by 40.15.

1.php
…
$s=3; /result of the calculation/
…

2.php
…
$force=$s*40.15;
…

Thx.

one. Either make it in the url(Which unless you want secret you can do it.)

But best is to register a session (In an array would be good). Then just check the session on the next page and output the data if nesscary

[cgraz]

pass it in the url

<a href="2.php?s=<? echo $s; ?>">Page 2</a>

Then on page 2.php

$force = $_GET['s'] * 40.15; 

Really depends on what you're doing. You could also pass it using hidden inputs or even use sessions. URL is probably the easiest, but like I said, depends on what you're doing.

Can you explain ”register a session (In an array would be good). Then just check the session on the next page and output the data if necessary”.

I will also thank you a lot if you can add a small example.

session_start(); would be the way you start it off

then

session_register("session_name");

now if you have an array called $array

make sure you do this before any output what so ever.

session_start();
$array=array(/*your array stuff here*/);
session_register("array");

//Next page do this
session_start("array");
//check if session registered
if(session_is_registered("array))
{
//echo the data
}
else
{
//do you stuff
}

Read up on sessions in the Manaul. Thats not the greatest example as it was done in less then 5mins
