Hi Im using a php theme script and I want to use jcart with this script. The thing is my theme scrip dosen't use echo.

 

When I need to display something I have to use something like this $_PAGE = "<div id='jcart'>..."

 

and if i use echo i recieve header error. i changed couple of thing and now i cant see cart but when i click add to cart button it says Item added but all cart is disappearing. you can see here

 

 

 

could you help me please thanks.

 

<THEME Name={ShopNavDivEnd}>
         </ul>
      </div>  
      
<br /><br /><br /><br />
<VAR>_JCART</VAR>
</div>
            
</THEME>

 

this is shop.php

$_JCART .= "<div id='jcart'>".$jcart->display_cart()."</div>";

 

i changed the jcart.php class to like this. I mean all echo to $_PAGE .= "..."

// Return specified number of tabs to improve readability of HTML output
