Need help..my script didn't work in PHP 5.2.1

[marmozzz]

hi 

i want to ask about script that i made..

it is about making cart using session

here the scripts

 

i summarize the script become like this:

 

<?php

session_start();

 

$menu=$_REQUEST["menu"];

 

$basket=$_REQUEST["id"];

 

if($basket!=""){

$_SESSION["basket"][$basket]=1;

}

 

$arrbasket=$_SESSION["basket"];

$count=count($arrbasket);

 

 

echo $count;

?>

<br>

<br>

P001 <a href="index.php?id=P001">Add</a><br>

P002 <a href="index.php?id=P002">Add</a><br>

P003 <a href="index.php?id=P003">Add</a><br>

P004 <a href="index.php?id=P004">Add</a><br>

 

<a href="index.php?menu=basket">show</a>

<br>

<br>

<?php

 

if($menu=="basket"){

echo "amount =$count<br>";

print_r($arrbasket);

}

 

?>

 

nah here comes the problem and i do not know the problem..

i am using PHP 5.1.2 and the scripts is OK, there is no problem...

 

but when I upload to my hosting and it user PHP 5.2.1

the session is error..

so when i add the id to the session it is done, but when i click show the session seems to be gone

the array in the session is gone exactly..

 

 

Please if you have any suggestion....

thanks before...

Try:

<?php
session_start();

// you should always check whether client defined variables (eg: _GET, _POST, _COOKIE, _SESSION, _REQUEST etc)
// exists before using them
if(isset($_REQUEST['id']) && !empty($_REQUEST['id']))
{
    $basket = $_REQUEST['id'];

    // check that the id has not already been added
    if(!isset($_SESSION['basket'][$basket]))
    {
        // not been add
        // we'll add the id to the basket session
        $_SESSION['basket'][$basket] = 1;

        // count how many items are in the basket session array
        echo count($_SESSION['basket']);
    }
    else
    {
        // id already added so we just notify the user
        echo $basket . ' - Already added';
    }

    echo '<hr>';
}
?>

P001 <a href="?id=P001">Add</a><br />

P002 <a href="?id=P002">Add</a><br />

P003 <a href="?id=P003">Add</a><br />

P004 <a href="?id=P004">Add</a><br /><br />

<a href="?menu=basket">show</a>


<?php

// again we check whether the variabe exists first before using it
// and that _REQUEST['menu''] is set to basket
if(isset($_REQUEST['menu']) && $_REQUEST['menu'] == 'basket')
{
    // count how many items are in the basket session array
    $count = count($_SESSION['basket']);

    // echo out the no. of items
    echo '<hr><br />amount = ' . $count;

    // show whats in the basket session
    echo '<pre>' . print_r($_SESSION['basket'], true) . '</pre>';
}

?>

yups, thank you very for much for the scripts..

 

I have learned much from your scripts

 

i have try it offline and there is no problem,

but still when i upload it

 

the amount is always 1

 

you can check it in this link (if you do not mind)

i wonder is it because of the PHP 5.2.1 in the hosting or else?

???

 

thank you very much

Looks like your site has a setting called regsiter_globals on. See if you can disable this setting as it is affecting your sessions.

 

When register_globals is on PHP automatically registers variables from user data, eg instead of using $_SESSION['basket'] you can just use $basket straight away. Having regsiter_globals on can cause security exploits within your code.

 

For now though change all $basket variables to $basket_id and your script should function as normal. But you should still try and get register_globals disabled.
