What is the best way to override text string in Magento module's Save.php?

Question

I just need to change one string which is hardcoded (this was surprise for me) in

vendor/magento/module-catalog/Controller/Adminhtml/Product/Attribute/Save.php ,

in execute() method:

 $this->messageManager->addSuccess(__('You saved the product attribute.'));

I must change 'You saved the product attribute.' to another text with plugins/rewrites. As far as I know, the plugin can change only arguments' values or return value. If I will use extending the class, I can just overwrite the method, but then I have to copy-paste all the method's code.

Is there a better way to change this one string?

Answer 1

To translate the text you can use translation feature of Magento2. If you are using custom theme then you just need to create en_US.csv (I am assuming you have this locale If you have different then you can create different csv i.e for German(de_DE.csv)).

app\design\adminhtml\YOUR_THEME_VENDOR\YOUR_THEMEN_NAME\Magento_Catalog\i18n\en_US.csv

In this CSV file, you need to write like this,

"You saved the product attribute.","Your custom message here"

Then just execute

php bin/magento s:s:d and clear your cache php bin/magento c:f
