ShoppingCart Infobox

[martigan]

Hi fellow Oscers,

 

What I search for here on the forums and in the contribution section

is a tool that can make the cart info box dissappearing when it?s empty and

to pop up when the first item has been added.

 

Ithink a simple if script will do but im not good with php :(..

 

Like:

 

If shopping cart is not empty do

 

show cart info box

 

else

 

......

 

Who can make this little if statement in php for me?

 

Thanks a lot,

Erik Ottens

Ok fixed it myself here is the code for in column_right.php :

 

$cart_contents_string = '';

if ($cart->count_contents() > 0) {

 

require(DIR_WS_BOXES . 'shopping_cart.php');

}

 

Thats all... show the shopping cart infobox only when needed ...

 

Maybe admins could move this topic to tips and tricks?

 

regards, erik.

Oh, man that is exactly waht I need!! Is there any way to implement that exact feature if you us the STS contribution? Any help would be great!!

Hi there,

 

Happy someone could use it ... I dont use sts myself but try

to search for

 

echo $sts_block['cartbox'];

 

in sts_display_output.php and replace it with

 

$cart_contents_string = '';

if ($cart->count_contents() > 0) {

 

echo $sts_block['cartbox'];

}

 

Please let me know if it worked out, can't test it here...

 

Regards Erik.

Thank you very much for your code and fast reply! :)

It looks like the code doesn't change anything, I can actually even remove all of this and it doesnt affect anything, strange...

This altered code

echo $sts_block['cartbox']; 

in sts_display_output.php and replace it with 

$cart_contents_string = '';
if ($cart->count_contents() > 0) {

echo $sts_block['cartbox']; 
}

 

make no difference at all, I can even remove it all and nothing happens. The cart box show up as usual, no change in behaviour.

 

This is how my cart box code looks like(bottom). I have added som a nice table layout that has the same looks as the rest of my shop. It's easy to make the cart disappear just by changing the code:

  $cart_contents_string = '????';

the '????' will show up when the cart is empty. I have removed all the usual box-graphics/tables so it only shows the text '????' so it does the job. The big problem is that I don't know how to add the extra html code for the new tablestructure that resides above and below the PHP-code. The html code shows also show up. I need to merge the html code into the php code I think so that it doesn't show upp when the cart is empty. I've already tried to merge it into the php-code but my php skills aren't really good so the result was not really that good.... Anyone? Regards, Markus!
