Filter product collection which only has image

Question

i try to filter product collection to get a product collection which only has at least one image like this:

  $collection->addAttributeToFilter('image', array("neq"=>'no_selection'));
  $collection->addAttributeToFilter('small_image', array("neq"=>'no_selection'));

but it's not working at all, it still shows the product with the placeholder image

Answer 1

Other idea ... get all unique entity_id (product Ids) from catalog_product_entity_media_gallery table and use result to filter collection.

$resource = Mage::getSingleton('core/resource');
$read     = $resource->getConnection('core_read');
$query    = $read->select()
    ->from($resource->getTableName('catalog_product_entity_media_gallery'), array('entity_id'))
    ->distinct(true)
    ->group('entity_id');
$result = $read->query($query);

$productIds = array();
while ($row = $result->fetch()) {
    $productIds[] = $row['entity_id'];
}

For your collection

$collection->addIdFilter($productIds);

Edit:

$collection->addAttributeToSelect('small_image, thumbnail, image');
$collection->addAttributeToFilter(
    array(
        array('attribute' => 'image','neq' => 'no_selection'),
        array('attribute' => 'small_image','neq' => 'no_selection'),
        array('attribute' => 'thumbnail','neq' => 'no_selection'),
    )
);

Note: for performance I'd use first approach.
