How to display a defined quantity other then 1 in basket

Tuesday 03 February 2004 11:39:30 am

I'using 3.3-2
I want to display the minimum quantity to be purchased for a product in the quantity text field in basket.tpl, which has this value: "{$Basket:ProductItem:item.item_count}"

I created a integer datatype in product class and gave it as identifier "item_count", in which to insert the minimum quantity.
Then I modified basket.php changing the string:

$item->setAttribute( "item_count", '1' );

into

$item->setAttribute( "item_count", $item_count );

The result is that after clicking 'Add to basket' it displays 0 as quantity.

I found no documentation for help. May someone give me some advice?

Regards.

Hi, Paul.
I think the code now is OK but basket still displays quantity 0.
This is now my basket.tpl code:

if ( $http->hasPostVariable( "ActionAddToBasket" ) )
{
    $objectID = $http->postVariable( "ContentObjectID" );
    $optionList =& $http->postVariable( "eZOption" );
    $object = eZContentObject::fetch( $objectID );
    $nodeID = $object->attribute( 'main_node_id' );
    $http->setSessionVariable( "FromPage", "/content/view/full/" . $nodeID . "/" );
    $item_count = 0;
    $price = 0.0;
    $isVATIncluded = true;
    $attributes = $object->contentObjectAttributes();
    foreach ( $attributes as $attribute )
    {
        $dataType =& $attribute->dataType();

        if ( $dataType->isA() == "ezprice" )
        {
            $priceObj =& $attribute->content();
            $price += $priceObj->attribute( 'price' );
        }
    }
       if ($attribute->attribute("name") == "item_count")
       {
        $item_count=$attribute->content();
        }

    $basket =& eZBasket::currentBasket();
    $sessionID = $http->sessionID();

    $item =& eZProductCollectionItem::create( $basket->attribute( "productcollection_id" ) );

    $item->setAttribute( "contentobject_id", $objectID );
    $item->setAttribute( "item_count", $item_count );
    $item->setAttribute( "price", $price );

Do you think integer datatype for item_count is ok? I see there is also an identifier datatype...

Thanks.

You are right Paul: I copied your code and cleared all caches manually, but the result is always 0 quantity.
In ezproductcollectionitem.php item_count is already defined this way:

  "item_count" => array( 'name' => "ItemCount",
                                                                'datatype' => 'integer',
                                                                'default' => 0,
                                                                'required' => true ),

This is maybe in contrast with what we added in basket.php:

if ($attribute->attribute("name") == "item_count")

Am I wrong?

Cheers.

Welcome back, Paul.

Changing the value works, so this is confirmed.
The debugging gives this output:

eZDebug::writeDebug( 'Checking for '.$attribute->attribute("name") ); if ($attribute->attribute("name") == "item_count")

Maybe I inserted the debug code badly in basket.tpl?

Hi Paul.
Sorry for the delay, just back from flu :(
This is the output I get now:

$attributeName=$attribute->attribute("name"); 
eZDebug::writeDebug( 'Checking for '.$attributeName ); 
if ($attribute->attribute("name") == "item_count") 

I was thinking to a more flexible solution. Suppose in product class we create an attribute (integer) called min_quantity, and suppose we want to display it in place of item_count attribute in basket.tpl (item_count must be equal to min_quantity)... Can we work directly in the template, without changing the kernel?

I receive no debug output if I insert the debugging code inside basket.php
If I insert the debugging code in basket.tpl I receive the same output wherever I insert it.

Unfortunately I'm a nerd with debugging.
What is the right place to put it?

Thanks a lot Paul!
These are the only three warnings I receive:
