Minimum quantity for different attributes

[camfab]

Hi,

I cannot find a solution to set a minimum order quantity for a product which have different attributes.

 

I explain with an example the problem (I sell t-shirt printed on demand):

 

I have a product "T-Shirt A". This product has several attributes: color (red,yellow,blue, etc) and size (S,M,L etc).

The costumer should buy at least 200 "T-Shirt", but this limit of 200 I would like to be present only on the entire product, not on the single attributes.

In other words, the costumers could buy 50 T-Shirt red S , 100 blue M and 50 red XL.

 

I've installed minimum order contribution, but this contrib set to 200 pcs each choice which I made (200 red S - 200 blue M and so on)

 

Is there a mod or contrib which can help me?

 

Thanks (and sorry for my english :blush: )

Pheraps I found a solution:

 

in the shopping_cart for each products (also with different attributes and options) I calculate the global quantity (i.e. 2 t-shirt red, 3 t-shirt royal, 1 t-shirt black --> total of 4 t-shirts)

 

If this result (4 t-shirt) is above the minimum order per quantity, I hide the "checkout" button to the user, and suggest him to add/change values of the articles that are under minimum

 

Here is the code:

 

shopping_cart.php, after about line 98

	$any_out_of_stock = 0;
$products = $cart->get_products();

 

insert

// BOF Minumum per Attribute

$any_under_minimum = 0;

//First loop: for each product "name" set initial quantity to 0
for ($i=0, $n=sizeof($products); $i<$n; $i++)
{
  $total_prod_qty[$products[$i]['name']]=0;
}

// Second loop: for each product get the quantity, indipendently by attributes and options
for ($i=0, $n=sizeof($products); $i<$n; $i++)
{
  if(MINIMUM_ORDERS == 'true')
  {
	$min_order_query = tep_db_query("select p.minorder as min_quant FROM " . TABLE_PRODUCTS . " p where p.products_id = '".$products[$i]['id']."'");
	while ($min_order = tep_db_fetch_array($min_order_query))
	{
		$total_prod_qty[$products[$i]['name']] += $products[$i]['quantity'];
	  $products[$i]['min_quant']=$min_order['min_quant'];
	}
  }
}
// Third loop: notice in case of products under minimum
for ($i=0, $n=sizeof($products); $i<$n; $i++)
{
  if ($total_prod_qty[$products[$i]['name']] < $products[$i]['min_quant'] )
  {
	$difference = $products[$i]['min_quant'] - $total_prod_qty[$products[$i]['name']];
	$any_under_minimum = 1;
	$cart_notice .= sprintf(MINIMUM_ORDER_NOTICE, $products[$i]["name"], $products[$i]["min_quant"], $difference);
  }
}
// EOF MINIM

 

and comments the part of code related to mimimum quantity contribution, about line 250

/*
//Minimum quantity code
if(MINIMUM_ORDERS == 'true'){
  $min_order_query = tep_db_query("select p.minorder as min_quant FROM " . TABLE_PRODUCTS . " p where p.products_id = '".$products[$i]['id']."'");
while ($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"]);
}

}
*/
//End Minimum quantity code

 

Finally, to hide checkout button:

				<td align="right" class="main">
			<?php
			if ($any_under_minimum == 0 && $any_out_of_stock == 0)
			{
			   echo '<a href="' . tep_href_link(FILENAME_CHECKOUT_SHIPPING, '', 'SSL') . '">' . tep_image_button('button_checkout.gif', IMAGE_BUTTON_CHECKOUT) . '</a>';
			}
			?></td>

 

Finally, I changed also the language files (languages/shopping_cart.php) :

define('MINIMUM_ORDER_NOTICE', 'The minimum order for article  "%s" is %d.<br>Insert at least %d articles also on different colours/size<br>');

 

What are you thinking about this solution ?
