[Plugin: eShop] Display shopping cart in sidebar WITHOUT using widgets

After some digging around I found some advice that I mangled into a wordpress function as follows:

// eShop Cart
function limelight_eshopcart()
{
echo display_cart($_SESSION[‘shopcart’.$blog_id],’true’, get_option(‘eshop_checkout’));
}

Very basic, and it did work to display the cart, but it would be much better if I could make it so the cart only appeared when it had something in it. I tried this, as I saw suggested in another thread:

// eShop Cart
function limelight_eshopcart()
{
if(isset($_SESSION[‘shopcart’.$blog_id]))
{
echo display_cart($_SESSION[‘shopcart’.$blog_id],’true’, get_option(‘eshop_checkout’));
}
}

but that caused it to not display at all. Any suggestions?

I would have thought control freaks would love widgets, as it gives them more control!

No widgets cannot be used other than via the widget interface, and this one in particular would be difficult to include by any other means, sorry.

What about my second post above? It’s working, sort of, as in it does display the cart….

set the 4th variable to ‘widget’ and see if that helps.

Sorry, but I’m pretty dumb with things like this, which is the fourth variable?

display_cart($_SESSION['shopcart'.$blog_id],'true', get_option('eshop_checkout'),'widget')

Unfortunately that didn’t make a difference. Oh well.

well you are trying to do something it wasn’t coded for ??

Hey,

The mistake in the code is pretty obvious, if anyone is still interested in this. You haven’t defined $blog_id; just add “global $blog_id;” to the beginning of your function and it works great.

Peace,

LOL, so simple I missed it.

I tired to follow this thread and edited my code so it looks like this:

// eShop Cart
function limelight_eshopcart()
{
global $blog_id;
if(isset($_SESSION['shopcart'.$blog_id]))
{
echo display_cart($_SESSION['shopcart'.$blog_id],'true', get_option('eshop_checkout'),'widget');
}
}

but still nothing is displayed with that code.

This version still works, though of course it displays the cart at all times, not just when it has something in it, which is not the desired behaviour.

// eShop Cart
function limelight_eshopcart()
{
echo display_cart($_SESSION['shopcart'.$blog_id],'true', get_option('eshop_checkout'));
}
