Problem with php sessions

[flit]

Hi there,

 

I have the following links on a page:

 

<a href="7.php<?php session_start(); $_SESSION['id']=1;?>">Test 1</a>

<br>

<a href="7.php<?php session_start(); $_SESSION['id']=2;?>">Test 2</a>

<br>

<a href="7.php<?php session_start(); $_SESSION['id']=3;?>">Test 3</a>

<br>

<a href="7.php<?php session_start(); $_SESSION['id']=8;?>">Test 8</a>

 

When I click the first link [test 1], the value 8 is written in the session file and not the value 1

When I click the second link I want the value 2 to be added into the session file. I want my

session file to look like this:

id|i:1,2;

 

Can somebody tell me what I am doing wrong??

i don't know but....

 

<a href="7.php?id=<?php session_start(); $_SESSION['id']=1; ?>">Test 1</a>

I used to use <a href='"7.php?action=add&id=1">Test 1</a>

But I don't want anything displayed into my web browser after 7.php

You only need to call session_start() only once . You don't call it everytime you want to use a session variable. You should call session_start() before any output. If you have any form of output you'll get either a blank page or an "header already sent" error message.

 

If you don't want PHP to continue the script at a certain pioint use die(); or exit;
