php - Programmatically Update Image Labels -


i'm trying update product images' labels. want them same name of product.

what i've tried

$mediamodel = mage::getmodel("catalog/product_attribute_backend_media"); $images = $product->getmediagalleryimages(); foreach ($images $image) {     $mediamodel->updateimage(         $product->getid(),         $image->getfile(),         array("label" => $title)     ); }

but error

fatal error: call member function getattributecode() on non-object in app/code/core/mage/catalog/model/product/attribute/backend/media.php on line 401

i've tried

$mediamodel = mage::getmodel("catalog/product_attribute_media_api"); $images = $mediamodel->items($product->getid()); foreach ($images $image) {         $mediamodel->update(         $product->getid(),         $image['file'],         array("label" => $title)     ); }

which runs fine, values aren't updated in admin.

how go this?

$product = mage::getmodel('catalog/product')->loadbyattribute('sku','xxxxxxxxx');  $mediamodel = mage::getmodel("catalog/product_attribute_media_api"); $images = $mediamodel->items($product->getid()); foreach ($images $image) {  $mediamodel->update(      $product->getid(),      $image['file'],      array("label" => 'image label here')   );  }  $product->getresource()->saveattribute($product, 'media_gallery');

this code works me. clear cache before refresh backend
