we use magento 2.1.9ce
Our products are made through an api. And they fill in the ean number at the image alt location. And unfortunatly they can't change that.
But i would like to have the products title on the img alt.
Can anyone help me with a script that copies the product title to the img alt?
I want to add another answer and leave my existing answer as feel this one is more what you are after but like both solutions. Below creates a new cli command within Magento for updating image alt tags so you can run on demand or via cron like you have requested.
<?xml version="1.0"?>

</argument>
</arguments>
</type>
</config>
etc/di.xml
This informs Magento about our new command and where to find it.

Console/Command/UpdateAltCmd.php
This is the logic for our new command and is added within the Console/Command directory of the module along with the usual module files. The above tells Magento what command initiates the script and then grabs all products. This then loops through each product adding the product name to each of the image alt tags.
Once module is installed or remade on your installation run the command by using bin/magento harrigo:updatealt from Magento root. I have currently only tested this with a handful of products with Magento 2.1.8 however seems to work fine.
Run from Specific Product ID:
This command can also be run with a starting product id by adding the ID to the end of the updatealt command.
e.g:
bin/magento harrigo:updatealt 100
Example of this module here: https://github.com/harrigo/ProductUpdateCmd
app/code/Harrigo/ProductUpdateCmd folder from Magento root directory.bin/magento setup:upgrade from Magento rootNot entirely sure that this is what you want but I would fix all your current products with an import.
From then on in use the below observer to make sure the products are saved with your name attribute in the alt tags.
Create a new module with below code:
<?php
namespace Harrigo\ProductUpdate\Observer\Catalog;
class ProductSaveBefore implements \Magento\Framework\Event\ObserverInterface
{
/**
* Execute observer
*
* @param \Magento\Framework\Event\Observer $observer
* @return void
*/
public function execute(
\Magento\Framework\Event\Observer $observer
) {
$_product = $observer->getProduct(); // get product object
//get title
$title = $_product->getName();
//get the images
$existingMediaGalleryEntries = $_product->getMediaGalleryEntries();
foreach ($existingMediaGalleryEntries as $key => $entry) {
//set new title for each image
$entry->setLabel($title);
}
//set the new labels for product
$_product->setMediaGalleryEntries($existingMediaGalleryEntries);
}
}
Harrigo/ProductUpdate/Observer/Catalog/ProductSaveBefore.php
Then set this to run before product save event:
<?xml version="1.0" ?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Event/etc/events.xsd">
<event name="catalog_product_save_before">
<observer instance="Harrigo\ProductUpdate\Observer\Catalog\ProductSaveBefore" name="harrigo_productupdate_observer_catalog_productsavebefore_catalog_product_save_before"/>
</event>
</config>
Harrigo/ProductUpdate/etc/events.xml
This was added within app/code with all the usual module files. Harrigo was the vendor and ProductUpdate the module name here.
Update
During testing this I have noticed an issue when deleting images for a products with this will post a further update when i get a chance.
