Install attributes through the php installer of a custom module

Question

Can anybody tell me how I can add multiple attributes in 1 install file of a custom module? In this case I also want to add them to the tab attributes but it doesn't work.

Just a beginner so I hope somebody can help me

Answer 1

Method getAttributeId accepts two parameters:

public function getAttributeId($entityTypeId, $id)
{
 if (!is_numeric($id)) {
 $id = $this->getAttribute($entityTypeId, $id, 'attribute_id');
 }
 if (!is_numeric($id)) {
 return false;
 }
 return $id;
}

And in your code you have three:

$attributeId = $installer->getAttributeId(
 'catalog_product',
 'test1'
 'test2'
);

You just have to repeat getAttributeId and addAttributeToSet for each attribute.

EDIT:

$attributeId = $installer->getAttributeId(
 'catalog_product',
 'affiliate_link2'
);
$installer->addAttributeToSet(
 'catalog_product',
 $defaultSetId,
 $groupId,
 $attributeId
);
$attributeId = $installer->getAttributeId(
 'catalog_product',
 'affiliate_link3'
);
$installer->addAttributeToSet(
 'catalog_product',
 $defaultSetId,
 $groupId,
 $attributeId
);

• Sander van Zuidam: Thanks for the details, I am trying it but doesn't work yet. Not sure what to do with the addAttributeToSet. In this code only the affiliate_link3 is added to the new tab Affiliate ideone.com/XJ5Qth
• Lord Skeletor: Hehe, you got it ;)

Answer 2

The actual syntax error is because you have a missing comma between your parameters. e.g:

$attributeId = $installer->getAttributeId(
 'catalog_product',
 'test1'
 'test2'
)

should be

$attributeId = $installer->getAttributeId(
 'catalog_product',
 'test1',
 'test2'
)

but as Reindex 'Em All has said, this function only accepts 2 paramaters so it should be

$attributeId = $installer->getAttributeId(
 'catalog_product',
 'test1'
)

You can only get an attributeId for one product at a time.
