Laravel Filament Upload Issue: "Failed to open stream: No such file or directory"

When working with Laravel Filament, a popular admin panel for Laravel, users might encounter an issue while uploading files. The error message "Failed to open stream: No such file or directory" can be quite frustrating. In this answer, we will discuss the possible causes and solutions for this issue.

First, let's discuss the possible causes for this error:

Incorrect file path: The most common cause for this error is an incorrect file path. Make sure that the file path specified in the Filament configuration is correct and accessible.
File permissions: Another possible cause is incorrect file permissions. Make sure that the directory where you want to store the uploaded files has the correct permissions.
PHP extensions: Ensure that the required PHP extensions for handling the file types you want to upload are installed and enabled.
CORS issue: If you are making an AJAX request to upload a file, there might be a CORS issue. Make sure that the server is configured to allow the request.

Now, let's discuss the possible solutions for this issue:

Check the file path: Make sure that the file path specified in the Filament configuration is correct and accessible. You can check the file path by adding the following line to your .env file:

FILAMENT_UPLOADS_DISK=public

Then, run the following command to check the disk path:

php artisan config:cache
php artisan config:clear

php artisan vendor:publish --provider="Spatie\MediaLibrary\MediaLibraryServiceProvider" --tag="config"

Check the config/filament.php file to ensure that the uploads key is set to the correct directory.

Check file permissions: Make sure that the directory where you want to store the uploaded files has the correct permissions. You can set the permissions using the following command:

sudo chmod -R 775 /path/to/directory

Replace /path/to/directory with the actual directory path.

Install and enable PHP extensions: Ensure that the required PHP extensions for handling the file types you want to upload are installed and enabled. You can check the installed PHP extensions by running the following command:

php -m

If the required extension is not installed, you can install it using your package manager or by downloading it from the official PHP website.

Configure CORS: If you are making an AJAX request to upload a file, there might be a CORS issue. You can configure CORS by adding the following lines to your .env file:

CORS=web:*
CORS_ALLOW_METHODS=GET,HEAD,PUT,POST,DELETE,OPTIONS
CORS_ALLOW_HEADERS=Accept,Accept-Language,Content-Language,Content-Type,DNT,Origin,User-Agent,X-CSRF-Token,X-Requested-With,X-Browser-ID,X-Browser-Name,X-Browser-Version,X-Device-ID,X-Device-Name,X-Installed-Channel,X-Platform,X-UA-Compatible,X-Requested-With,X-Proto,Access-Control-Expose-Headers,Access-Control-Allow-Credentials,Authorization,X-CSRF-Token,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-With,X-Requested-
