Set Base Image Programmatically - php

Question

I've got this problem that I can't solve. Partly because I can't explain it with the right terms. I'm new to this so sorry for this clumsy question.
Below you can see an overview of my goal.
I am trying to sell Similar product in my magento for this i wrote some code that every thing is working fine..
But i have only one problem with images..
that is I am getting all images of current product but the base image is not selected, How can i set the very first image as base image Programmatically.
Any ideas ?

Answer 1

Hello You can do as follows :
$image =$imagePath."image.png";
$product->setMediaGallery(array('images'=>array (), 'values'=>array ()));
if(is_file($image))
{
$product->addImageToMediaGallery($image, array ('image', 'small_image', 'thumbnail'), false, false);
}
i.e you need to first set the media gallery, P.S This is a necessary step.
then add all images to gallery using addImageToMediaGallery where 'image' ref to 'base_image'
i.e in above example we are setting image.png to base_image, small_image and thumbnail image in a single call.
hope this helps you.

I've achieved the same result by using:
$product->setSmallImage($path)
->setThumbnail($path)
->setImage($path)
->save();
Works better for the case where your media gallery has one or more pictures in it.
I'm doing
$product->load();
$gallery = $product->getMediaGalleryImages();
$paths = array();
foreach ($gallery as $image) {
$paths[] = $image->getFile();
}
sort($paths);
$path = array_shift($paths);
try {
$product->setSmallImage($path)
->setThumbnail($path)
->setImage($path)
->save();
} catch (Exception $e) {
echo $e->getMessage();
}
Which gets all the product images, sort's them by file name and sets the first to the product primary image. As I ran a import and added all my pictures, but didn't set the primary image.
To grab a set or "broken" products I used:
$collection = Mage::getModel('catalog/product')
->getCollection()
->addAttributeToFilter('small_image', array('eq' => ''));
