[SOLVED] Returning values problem - please help

[greg]

Sorry, I'm new to php and I need some help.

 

I have the following code to return the recent products viewed by visitors. I want to return these values, EXCEPT the last product viewed. Could anyone help me please.

hummm.. and the code is ?

[greg]

OH my God!!!  ... here is it.

if (!tep_session_is_registered('recently_viewed'))
	{
	tep_session_register('recently_viewed');
	$recently_viewed = $HTTP_GET_VARS['products_id'] . ';';
	}
$check_not_duplicate = $HTTP_GET_VARS['products_id'];
$temp_recent = $recently_viewed;
if (!ereg($check_not_duplicate, $temp_recent ) )
 	$recently_viewed = $HTTP_GET_VARS['products_id'] . ';' . $recently_viewed ;
?>

you mean something like this

<?php
if (!isset($_SESSION['recently_viewed']) )
{
      //set session as array
      $_SESSION['recently_viewed'] = array();
}
//add to array
$_SESSION['recently_viewed'][] = $HTTP_GET_VARS['products_id'];
//remove dups
$_SESSION['recently_viewed'] = array_unique($_SESSION['recently_viewed']);
?>

//remove last item
$tmp = array_pop($tmp);
//create ; delimited string
$tmp = implode(";",$tmp);
//display string
echo $tmp;

[greg]

Thank you MadTechie.

I still have a little problem with this. The first part produce only one value in the array, the last product viewed.

On the second part, I don't get any results at all. This is what I did:

//remove last item

$tmp = array_pop($_SESSION['recently_viewed']);

//create ; delimited string

$tmp = implode(";",$_SESSION['recently_viewed']);

//display string

echo $tmp;

 

I think may be the other part of the code has something to change but I don't know how do it.

 

Thank you for your help.

Heres a quick script to show how i would use it..

Please note i upgraded 
$HTTP_GET_VARS to $_GET and
changed the way sessions are called

i also added some emulation to save entering lots of different URLs but it grabs the first one

[code?tester.php?products_id=123456789]
<?php
session_start();
Add(); //Grab First one from URL
echo "<br>---<br>";

/*EMULATE START -- remove from live code*/
$_GET['products_id'] = 1; //emulate new entry
Add();
echo "<br>---<br>";
$_GET['products_id'] = 2; //emulate new entry
Add();
echo "<br>---<br>";
$_GET['products_id'] = 4; //emulate new entry
Add();
echo "<br>---<br>";
$_GET['products_id'] = 8; //emulate new entry
Add();
echo "<br>---<br>";
$_GET['products_id'] = 10; //emulate new entry
Add();
echo "<br>---<br>";
$_GET['products_id'] = 20; //emulate new entry
Add();
echo "<br>---<br>";
/*EMULATE END*/

$tmp = $_SESSION['recently_viewed'];
//remove last item
array_pop($_SESSION['recently_viewed']);
//create ; delimited string
$tmp = implode(";",$tmp);
//display string
echo $tmp;

//reset (comment out to keep them)
#unset($_SESSION['recently_viewed']);

function Add()
{
if (!isset($_SESSION['recently_viewed']) )
{
      //set session as array
      $_SESSION['recently_viewed'] = array();
}
//add to array
$_SESSION['recently_viewed'][] = $_GET['products_id'];
//remove dups
$_SESSION['recently_viewed'] = array_unique($_SESSION['recently_viewed']);
echo "Added:->".$_GET['products_id'];
}
