Use the product and attribute manager:

Code: Select all

$attrManager = \Aimeos\MShop::create( $context, 'attribute' );
$manager = \Aimeos\MShop::create( $context, 'product' );

$attrItem = $attrManager->create()->setCode( 'value' )->setType( 'test' );
$prodItem = $manager->create()->setCode( 'test' );
$listItem = $manager->createListItem();

$prodItem->addListItem( 'attribute', $listItem, $attrItem );
$manager->save( $prodItem );
This creates a new attribute item and attaches it to a new product item.

Use e.g.

Code: Select all

$manager = \Aimeos\MShop::create( $context, 'product' );
$manager->get( $product_id, ['attribute', 'media', 'price', 'text'] );

I use this code

Code: Select all

        $manager = \Aimeos\MShop::create( $context, 'product' );
        $attrManager = \Aimeos\MShop::create( $context, 'attribute' );
        $manager->get( $product_id, ['attribute', 'media', 'price', 'text'] );
        $attrItem = $attrManager->create()->setCode( 'value' )->setType( 'test' );
        $prodItem = $manager->create()->setCode( 'test' );
        $listItem = $manager->createListItem();
        $prodItem->addListItem( 'attribute', $listItem, $attrItem );
        $manager->save( $prodItem );
But it appears

You have to use the product item you are fetching and not create another one afterwards. Use this code instead:

Code: Select all

        $manager = \Aimeos\MShop::create( $context, 'product' );
        $attrManager = \Aimeos\MShop::create( $context, 'attribute' );
        $prodItem = $manager->get( $product_id, ['attribute', 'media', 'price', 'text'] );
        $attrItem = $attrManager->create()->setCode( 'value' )->setType( 'test' );
        $listItem = $manager->createListItem();
        $prodItem->addListItem( 'attribute', $listItem, $attrItem );
        $manager->save( $prodItem );
Note: This code will fail when running twice because the attribute and listitem will be created again and you will receive a duplicate error from the database.

Thank you for this, it works :o :o :o .

Last question how about to validate if attribute exist ? just add it on a product only.

Use something like this:

Code: Select all

$attrMap = [];
foreach( $prodItem->getListItems( 'attribute', null, null, false ) as $listItem ) {
	if( $refItem = $listItem->getRefItem() ) {
		$attrMap[$refItem->getType()][$refItem->getCode()] = $listItem;
	}
}

if( !isset( $attrMap['test']['value'] ) ) {
        $attrItem = $attrManager->create()->setCode( 'value' )->setType( 'test' );
        $listItem = $manager->createListItem();
        $prodItem->addListItem( 'attribute', $listItem, $attrItem );
}
