How to change default quantity in add to shopping cart?

[jashnu]

Hi!

 

I'd like to change the default quantity added to the shopping cart when you click add to cart from 1 to 4. I think it should be changed in classes/shopping_cart.php

 

function add_cart($products_id, $qty = '1', $attributes = '', $notify = true) {

 

but that doesn't work? Can anyone help me please? Thanks in adcance.

This is easiest done by changing the (catalog)/includes/application_top.php

Search for

	  // customer adds a product from the products page
  case 'add_product' :	if (isset($HTTP_POST_VARS['products_id']) && is_numeric($HTTP_POST_VARS['products_id'])) {
							$cart->add_cart($HTTP_POST_VARS['products_id'], $cart->get_quantity(tep_get_uprid($HTTP_POST_VARS['products_id'], $HTTP_POST_VARS['id']))+1, $HTTP_POST_VARS['id']);
						  } else {
							  if (isset($HTTP_GET_VARS['products_id'])) {
							  $cart->add_cart($HTTP_GET_VARS['products_id'], $cart->get_quantity($HTTP_GET_VARS['products_id'])+1);
							}
						  }
						  tep_redirect(tep_href_link($goto, tep_get_all_get_params($parameters)));
						  break;
  // performed by the 'buy now' button in product listings and review page
  case 'buy_now' :		if (isset($HTTP_GET_VARS['products_id'])) {
							if (tep_has_product_attributes($HTTP_GET_VARS['products_id'])) {
							  tep_redirect(tep_href_link(FILENAME_PRODUCT_INFO, 'products_id=' . $HTTP_GET_VARS['products_id']));
							} else {
							  $cart->add_cart($HTTP_GET_VARS['products_id'], $cart->get_quantity($HTTP_GET_VARS['products_id'])+1);
							}
						  }
						  tep_redirect(tep_href_link($goto, tep_get_all_get_params($parameters)));
						  break;

and change the

+1

to

+4

 

This will add always 4 of a product with buy now and add to cart

Thanks a lot! I wouldn't have thought it's there. Seems to be working perfectly.

Can this be done on a per product basis?

This is kind of per product ?! Instead of 1 there will always be 4, in the above case, added of a certain product.

Let me clarify. What I mean is quantity 1 for most items, but quantity 5 or 10 for others.

 

TIA.

I see what you mean. That could be fairly simple done I guess. Somewhere you can assign quantities to your products, ie. by adding an extra database field for that purpose, and make the +1, +4 or whatever a variable depending on that value.

So something like

$cart->add_cart($HTTP_GET_VARS['products_id'], $cart->get_quantity($HTTP_GET_VARS['products_id'])+$product_quantitiy);

where $product_quantity is assigned a value before.

I'll give it a shot it. Thanks.

Thanks this information was very helpful in finding a solution to a problem I was having -- knowing the cart quantity was handled in the application top helped me to troubleshoot the changes.
