[eluser]the_unforgiven[/eluser]
Hi all,

I'm getting the following error:

Code:

A PHP Error was encountered

Severity: Warning
Message:  Invalid argument supplied for foreach()
Filename: inc/header.php
Line Number: 76

On or around the above mentioned line is this:

Code:

<img src="&lt;?php echo base_url(); ?&gt;images/bag.png" width="29" height="29" alt="Cart" />&nbsp;You have: <a href="&lt;?php echo base_url(); ?&gt;">
   &lt;?php $cart = $this->session->userdata('cart');
    if (count($this->session->userdata('cart'))){
    $count = 1;
     foreach ($this->session->userdata('cart') as $PID => $row) {    
        echo $row['count'];
           }  
     }
   ?&gt;
</a> <span>items in your cart</span>
