Magento – How to set thumbnail image programmatically in Magento 2

imagemagento2products

How can I set main product image as thumbnail image programmatically in Magento 2?

Scenario:

I have a loop running trough all products and each product has a main image, only some products have not defined an image for thumbnail. So I want to set the main image also as the product thumbnail for each product.

Thank you for the reply.

I already found the answer by myself and I will share it below.

foreach ($products as $product){

    $smallImage = $product->getSmallImage();
    $imagePath  = '/catalog/product' . $product->getImage();

    if( $smallImage == 'no_selection' ){
        echo 'FIXING ' . $imagePath . "\r\n";
        $product->addImageToMediaGallery( $imagePath, array( 'small_image' ), false, false );
        $product->save();
    }
}

But still, I'm curious to know what are the Boolean variables are here.

$product->addImageToMediaGallery( $imagePath, array( 'small_image' ), false, false );

Programmatically Set or Change Thumbnail Image from Gallery

If I understand you correctly, you just want to change FR to FL for the thumbnail?

Just do this:

$collection = Mage::getModel('catalog/product')->getCollection()->addAttributeToSelect('thumbnail);
foreach($collection as $product) {
    $product->setThumbnail(str_replace('_FR', '_FL', $product->getThumbnail());
}
$collection->save();

Here is given programmatically adding media images to product, you can adjust this code to your own importing script:

    $mediaGalleryAttribute = Mage::getModel('catalog/resource_eav_attribute')
        ->loadByCode(Mage_Catalog_Model_Product::ENTITY, 'media_gallery');
    $mediaGallery          = $mediaGalleryAttribute->getBackend();
    $attrCode              = $mediaGalleryAttribute->getAttributeCode();


    $product          = Mage::getModel('catalog/product')->load($productId);
    $mediaGalleryData = $product->getData($attrCode);
    /**
     * If you want to remove old images use this code
     */
    if (isset($mediaGalleryData['images'])) {
        foreach ($mediaGalleryData['images'] as &$image) {
            $image['removed'] = 1;
        }
        $product->setData($attrCode, $mediaGalleryData);
    }
    /**
     * Here is real image file path
     */
    $thumbnailFile = 'real/path/to/thumbnail/file.jpg';
    $imageFile     = 'real/path/to/image/file.jpg';
    try {
        //Set thumbnail
        $imageFileUri = $mediaGallery->addImage($product, $thumbnailFile, null, false, false);
        $mediaGallery->setMediaAttribute($product, 'thumbnail', $imageFileUri);

        //Set image (or base image, small image whatever you want
        $imageFileUri = $mediaGallery->addImage($product, $imageFile, null, false, false);
        $mediaGallery->setMediaAttribute($product, 'image', $imageFileUri);
        $product->save();
    } catch (Exception $e) {
        Mage::logException($e);
    }
