No products are added to the shopping cart

nachotator · April 12, 2010

Hello, I have a problem with one of my oscommerce, the fact is that testing it I realize that none of the buttons to add to cart works properly.

For you to see what the shop where the problem if you want to try is http://www.lascositasdepatry.com, well if you want to try you say that if I give the button "Add to Cart" that exist in the home page of any of the products is that instead of adding to cart button it does is go to the category of product, and you have the button code is this:

This is in the file includes / modules / new_products.php

 <td width="94"> <a href = "'. Tep_href_link (FILENAME_DEFAULT, tep_get_all_get_params (array (' action ')).' Action = buy_now & products_id = '. $ New_products [' products_id ']).'" > '. tep_image_button ('lyly2.jpg' IMAGE_BUTTON_IN_CART). '</ A> </ td>

Then it turns out that the button "Buy" from the screen that brings me to tighten it does not work, leads me to nowhere or I carried the same screen and the button code is this:

It is found in the file includes / modules / product_listing.php

 case 'PRODUCT_LIST_BUY_NOW': 
           $ Lc_align = 'center'; 
           $ Lc_text = '<a href="'. Tep_href_link(basename($PHP_SELF), tep_get_all_get_params(array('action')).'action=buy_now&products_id='. $listing['products_id']).'">'. tep_image_button ('Button_buy_now.gif' Buy Now). '</ A>';

Then I go is within each product, where the decryption and I to add to cart button'm the same as the previous, that does not lead me to any site or leads me to the same page where I am and the button code is this:

It is in the file product_info.php

 class="main" <td align="right"> <? Tep_draw_hidden_field php echo ('products_id', $ product_info ['products_id']). tep_image_submit ('button_in_cart.gif' IMAGE_BUTTON_IN_CART);?> </ td>

As you can see it does not work either, someone can tell me that is? Somebody help me please.

I tried even to other oscommerce code I have and working properly but here do not work, it might be something from the database? Is not think of anything.

A greeting.

check the following code:

// 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'], $HTTP_POST_VARS['id']))+$_POST['quantity'], $HTTP_POST_VARS['id']);
	}
	tep_redirect(tep_href_link($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;

in /catalogue/includes/application_top.php file

I just checked and can not find the code, is this code? Where I have to put it? If you want to put all the code so you can see aplication_top.php.

try to add the following code:

// 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'], $HTTP_POST_VARS['id']))+$_POST['quantity'], $HTTP_POST_VARS['id']);
}
tep_redirect(tep_href_link($goto, tep_get_all_get_params($parameters)));
break;

after:

case 'cust_order' : if (tep_session_is_registered('customer_id') && isset($HTTP_GET_VARS['pid'])) {
if (tep_has_product_attributes($HTTP_GET_VARS['pid'])) {
tep_redirect(tep_href_link(FILENAME_PRODUCT_INFO, 'products_id=' . $HTTP_GET_VARS['pid']));
} else {

}
}
tep_redirect(tep_href_link($goto, tep_get_all_get_params($parameters)));

Hi, nachotator

I have exactly the same problem. No products can be added to the shopping cart.

Did you solve the problem? If yes, could you tell me how, please?

Thanks and greetings

No products are added to the shopping cart
