Variables

Nickosssss

Hello,

I have a series of php files. in the first php file i have 3 text fields in a form in which i have the 3 variables....

How can i use the same variables on the other php files without the need ot submitting a form?

For example:

one.php -> has the form and the text fields

sumbit

two.php displays the variables

but

three.php cannot

Probably the easiest way is to use sessions. You would place

<?
session_start();
?>

at the top of one.php and two.php. In one.php, you'd set the session variables as

$_SESSION['var1']="somevar";
$_SESSION['var2']="somevar";
etc.

and in two.php

$var1=$_SESSION['var1'];
$var2=$_SESSION['var2'];
$_SESSION=array();  //clears vars so three.php cannot access them

thanks for the help

well it works if i have simples code files

but because i need to verify the value of text fields with the database...there it doesnt work 🙁

Can you post your code? It's not really clear to me what you are trying to do.

------------------------------- FILE: 1 -> stud.php -------------------------

OK! Well, the first file has the form in which the user inputs the details!

The second file verifies if the details exist on the database!

The third file is just for going on...But i need the details inputed from the 1st file to the 3rd file so can do some other select. However, the values do not pass and although i tried the session_start().

If i dont use the mysql statements then its ok i can access them.

NOTE: i have erased some lines in order ot be less confusing...thanks
