Web Hosting Talk : Web Hosting Main Forums : Programming Discussion : PHP save values in classes from page to page

[TranceNote]

Hello!

I have just started to use classesin php, I did this because I wanted my webbapplikation to work more like a ordinary software.

Now im trying to figure how I should make the variables keep their values from page to page,

Ive read on php.net that I can use session_register() for this, and that I can save a whole class in with this. But how do I "extract" it from the session afterwards?

for example I got this class:

PHP Code:

class test {

         var $test1;
         var $test2;

          function write() {
                      $this->test1 += 1;
                      $this->test2 += 1;
                      echo "$this->test1 and $this->test2";

          }
} 


I call for the function write

$this->write();

and then I call for it once again but later on another page
Now I want it to output "2 and 2" not "1 and 1"

I dont know more how I can explain it, can someone help me on this, or show an example how you save the class in a session and can use its methods on other pages (I know I have to include the class on all pages) with the values left.

Best Regards

Hi,

You have to call the function session_start() on the second page, and then you can retrieve the values you stored in session variable by simply specifying the variable name.

Gaah stupid me, I used session_start() but I re-declared the variable =)

Thank you!
