Laravel-Validation-TR Turkish Validation file for Laravel. Copy the contents of the Resources > lang > en folder and create a folder named tr in the same directory path and paste the files you copied into it. Open the "validation.php" file in the tr folder we just created, delete everything in its content and paste the content I shared there. Go to Config > app.php. Change the code in the " 'locale' => 'en' " section here to " 'locale' => 'tr' ". All transactions will be completed.
