How do I add id's to a session?

[flit]

Hi there,

 

I am trying to add id's to a session, but when I click on a link to enter the id into the session,

it overwrites it and does not add an id to the session.

 

I have a page called 6.php with the following lines:

<a href="7.php<? php

session_start();

$_SESSION['id']='1';?>">Test 1</a>

-->writes to the session: id|s:1:"1";

 

<br>

 

<a href="7.php<? php

session_start();

$_SESSION['id']='2';?>">Test 2</a>

-->writes to the session: id|s:1:"2";

 

I want to be able to add an id into the session and not overwrite it.

Can anyone help me?

Try this:

 

<a href="7.php<? php
session_start();
$_SESSION['id'][] ='1';?>">Test 1[/url]
-->writes to the session: id|s:1:"1";




<a href="7.php<? php
session_start();
$_SESSION['id'][]='2';?>">Test 2[/url]
-->writes to the session: id|s:1:"2";

 

You need to treat it like an array

Thanks dude, it worked!

 

Another id was added to the session. Can I use the foreach statement later to retrieve data from a database like they are stored?

 

-> id|a:4:{i:1;s:1:"1";.........;}

I can't add the same id to the session more than once

When I added some more links, the program writes the id of the last link to the session thus 8

 

<a href="7.php<? php

session_start();

$_SESSION['id']='1';?>">Test 1[/url]

 

<a href="7.php<? php

session_start();

$_SESSION['id']='2';?>">Test 2[/url]

 

<a href="7.php<? php

session_start();

$_SESSION['id']='3';?>">Test 3[/url]

 

<a href="7.php<? php

session_start();

$_SESSION['id']='8';?>">Test 8[/url]

 

Help?

Where are the id's coming from, and what exactly is it that you want it to do?  You say that right now it's writing the id of the last link, what is it supposed to do?

[p2grace]

BTW you can use a foreach statement later to view the ids in the session.

When I press the first link I want to write 1 to the session file but when I press 1 it writes 8 to the session file

 

When I press the second link I want to write 2 to the session file but when I press 2 it writes 8 to the session file

 

When I press the third link I want to write 3 to the session file but when I press 3 it writes 8 to the session file

 

I want my session file to look like this:

1,2,3,8.......

 

I used to do this with <a href="99.php?action=add&id=1">Add id 1 to session</a>

but I don't want to use that technique. I don't want the action=add&id=1 message printed

in my web browser. I want to add id's like the links below.

 

<a href="7.php<? php

session_start();

$_SESSION['id']='1';?>">Test 1[/url]

 

<a href="7.php<? php

session_start();

$_SESSION['id']='2';?>">Test 2[/url]

 

<a href="7.php<? php

session_start();

$_SESSION['id']='3';?>">Test 3[/url]

 

<a href="7.php<? php

session_start();

$_SESSION['id']='8';?>">Test 8[/url]

 

All I want to do is insert a id value into a session by clicking on a link, and retrieve the id's later to print some mysql info on a page
