Help adding a checkbox

[slamdunk]

Hello Guys,

 

I'm a novice. I'm using oscommerce for a small shopping cart. I want to replace each "add to cart" button with a checkbox and display only one "add to cart" button at the bottom of the page which adds every product checked in the product listing to the shopping cart.

 

I found a addon on oscommerce which does this job but it displays only 1 item per row while I want to display 4 item. But I'm not able to replace "add to cart" button with a checkbox on the original file. Please help adding the checkbox to the original file. I'm very new to php. The files are attached to give more idea.

 

product_listing.php is the original with “add to cart” button

 

product_listing_multi.php does the job however it displays only one item per row. Both screenshots are attached.

 

Thanks in advance!
