Minimum and Maximum Quantity per product

[juanpalomo]

I have installed the contribution Minimum Product Quantity with Admin but I need also to have a maximum of weeks for the products we sell (language courses). That's why I have tried to transform the contribution so that I can offer courses that can be booked for a time between e.g. 3 and 8 weeks.

 

I have got, more or less, that the things work, but I have a problem. When I use following code in catalog/shopping_cart.php

 

//Min_Max quantity code
if(MAXIMUM_ORDERS == 'true'){
  $max_order_query = tep_db_query("select p.maxorder as max_quant FROM " . TABLE_PRODUCTS . " p where p.products_id = '".$products[$i]['id']."'");
  $min_order_query = tep_db_query("select p.minorder as min_quant FROM " . TABLE_PRODUCTS . " p where p.products_id = '".$products[$i]['id']."'");

while ($max_order = tep_db_fetch_array($max_order_query))  {
  if ($products[$i]['quantity'] > $max_order['max_quant'] ) {
		$products[$i]['max_quant']=$max_order['max_quant'];
  }
}
 if ($products[$i]['quantity'] > $products[$i]['max_quant'] ) {
 	$products[$i]['quantity']=$products[$i]['max_quant'];
	$cart->add_cart($products[$i]['id'],$products[$i]['quantity'],$products[$i]['attributes']);
	$cart_notice = sprintf(MAXIMUM_ORDER_NOTICE, $products[$i]["name"], $products[$i]["max_quant"],$products[$i]['attributes']);
}

while ($min_order = tep_db_fetch_array($min_order_query))  {
  if ($products[$i]['quantity'] < $min_order['min_quant'] ) {
		$products[$i]['min_quant']=$min_order['min_quant'];
  }
}

	 if ($products[$i]['quantity'] < $products[$i]['min_quant'] ) {
 	$products[$i]['quantity']=$products[$i]['min_quant'];
	$cart->add_cart($products[$i]['id'],$products[$i]['quantity'],$products[$i]['attributes']);
	$cart_notice = sprintf(MINIMUM_ORDER_NOTICE, $products[$i]["name"], $products[$i]["min_quant"],$products[$i]['attributes']);
}

}
//End Min_Max quantity code

 

everything seems to work fine and I can put less than the minimum or more than the maximum weeks in the shopping cart, and the cart shows up the right quantity (min or max), but... when I leave the shopping_cart site in order to continue shopping and come back to her (cart contents), it falls ALWAYS to the minimum, the right quantity doesn't remains there.

 

Can anyone of you see a solution for this problem? thanks :blush:
