💡 Hint

Common Mistakes

Choosing 'public' instead of 'local' as default disk.

Using cloud disks like 's3' without proper setup.

The default filesystem disk is usually set to 'local' for local storage in Laravel.

Complete the code to define a disk driver in Laravel's filesystem config.

Laravel

'disks' => [
    'local' => [
        'driver' => '[1]',
        'root' => storage_path('app'),
    ],
],

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using 'ftp' or 's3' drivers for local disk configuration.

Confusing 'public' with 'local' driver.

The 'local' disk uses the 'local' driver to store files on the server's local filesystem.

Fix the error in the disk configuration to correctly set the visibility.

Laravel

'public' => [
    'driver' => 'local',
    'root' => storage_path('app/public'),
    'visibility' => '[1]',
],

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Setting visibility to 'private' or 'hidden' for public disk.

Using invalid visibility values.

The 'visibility' option should be set to 'public' to allow public access to files in the 'public' disk.

Fill both blanks to configure an S3 disk with correct driver and region.

Laravel

's3' => [
    'driver' => '[1]',
    'region' => '[2]',
    'bucket' => env('AWS_BUCKET'),
],

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using 'local' as driver for S3 disk.

Setting region to an invalid value.

The S3 disk requires the 's3' driver and a valid AWS region like 'us-east-1'.

Fill all three blanks to create a custom FTP disk configuration.

Laravel

'ftp_custom' => [
    'driver' => '[1]',
    'host' => env('FTP_HOST'),
    'username' => env('FTP_USERNAME'),
    'password' => env('FTP_PASSWORD'),
    'port' => [2],
    'root' => '[3]',
],

Drag options to blanks, or click blank then click option'

Attempts:

💡 Hint

Common Mistakes

Using 's3' as driver for FTP disk.

Setting port to a string instead of a number.

Leaving root path empty or incorrect.

FTP disks use the 'ftp' driver, default port 21, and a root path for file storage.

Practice

1. What is the purpose of the default key in Laravel's config/filesystems.php file?

easy

A. It sets the default storage disk Laravel uses for file operations.

B. It defines the maximum file size allowed for uploads.

C. It specifies the encryption method for stored files.

D. It lists all available storage disks in the application.

Solution

1. Step 1: Understand the role of the default key

   The default key in config/filesystems.php tells Laravel which disk to use when no specific disk is mentioned.

2. Step 2: Compare with other options

   Options A, B, and C describe unrelated settings. Only "It sets the default storage disk Laravel uses for file operations." correctly describes the default disk setting.

3. Final Answer:

   It sets the default storage disk Laravel uses for file operations. -> Option A

4. Quick Check:

   Default disk = storage location [OK]

Hint: Default disk means where files go if no disk specified [OK]

Common Mistakes:

• Confusing default disk with file size limits
• Thinking default sets encryption
• Assuming default lists all disks

2. Which of the following is the correct syntax to define a local disk in config/filesystems.php?

easy

A. 'local' => ['driver' => 'ftp', 'root' => storage_path('app')],

B. 'local' => ['driver' => 'local', 'root' => storage_path('app')],

C. 'local' => ['driver' => 's3', 'root' => storage_path('app')],

D. 'local' => ['driver' => 'local', 'root' => public_path('app')],

Solution

1. Step 1: Identify the correct driver for local disk

   The local disk uses the 'local' driver, so options with 'ftp' or 's3' are incorrect.

2. Step 2: Check the root path for local storage

   The root path for local disk is usually storage_path('app'), not public_path('app').

3. Final Answer:

   'local' => ['driver' => 'local', 'root' => storage_path('app')], -> Option B

4. Quick Check:

   Local driver + storage_path = correct syntax [OK]

Hint: Local disk uses 'local' driver and storage_path root [OK]

Common Mistakes:

• Using wrong driver like 'ftp' or 's3' for local disk
• Setting root to public_path instead of storage_path
• Mixing driver and root paths

3. Given this config/filesystems.php snippet:

'disks' => [
    's3' => [
        'driver' => 's3',
        'key' => env('AWS_ACCESS_KEY_ID'),
        'secret' => env('AWS_SECRET_ACCESS_KEY'),
        'region' => env('AWS_DEFAULT_REGION'),
        'bucket' => env('AWS_BUCKET'),
    ],
],
'default' => 's3',

What happens when you call Storage::put('file.txt', 'Hello') in your app?

medium

A. An error occurs because the local disk is not set.

B. The file is saved to the local storage folder.

C. The file is saved to the configured Amazon S3 bucket.

D. The file is saved to a temporary directory.

Solution

1. Step 1: Identify the default disk

   The default disk is set to 's3', so all Storage calls use the S3 disk unless specified otherwise.

2. Step 2: Understand Storage::put behavior

   Calling Storage::put saves the file to the default disk, which is the S3 bucket configured.

3. Final Answer:

   The file is saved to the configured Amazon S3 bucket. -> Option C

4. Quick Check:

   Default disk 's3' means files go to S3 [OK]

Hint: Default disk controls Storage::put location [OK]

Common Mistakes:

• Assuming file saves locally despite default 's3'
• Thinking missing local disk causes error
• Confusing temporary directory with storage

4. You added a new disk in config/filesystems.php but get an error when using it. Which of these is the most likely cause?

medium

A. You forgot to run php artisan config:cache after changing the config.

B. You used the wrong PHP version for Laravel.

C. You did not install the Laravel UI package.

D. You set the disk name to 'default' instead of a unique name.

Solution

1. Step 1: Understand Laravel config caching

   Laravel caches config files for performance. Changes in config files require clearing or caching again.

2. Step 2: Identify the common fix

   Running php artisan config:cache refreshes the cached config and applies new disk settings.

3. Final Answer:

   You forgot to run php artisan config:cache after changing the config. -> Option A

4. Quick Check:

   Config cache must refresh after edits [OK]

Hint: Run config:cache after config changes [OK]

Common Mistakes:

• Ignoring config cache after edits
• Blaming PHP version for config errors
• Confusing unrelated packages with filesystem config

5. You want to configure a new disk in config/filesystems.php that stores files on a remote FTP server. Which of these is the correct minimal configuration?

hard

A. 'ftp' => [ 'driver' => 's3', 'key' => env('FTP_KEY'), 'secret' => env('FTP_SECRET') ],

B. 'ftp' => [ 'driver' => 'local', 'root' => env('FTP_HOST') ],

C. 'ftp' => [ 'driver' => 'ftp', 'bucket' => env('FTP_BUCKET') ],

D. 'ftp' => [ 'driver' => 'ftp', 'host' => env('FTP_HOST'), 'username' => env('FTP_USERNAME'), 'password' => env('FTP_PASSWORD') ],

Solution

1. Step 1: Identify the correct driver for FTP

   The driver must be 'ftp' to connect to an FTP server, so options with 'local' or 's3' are incorrect.

2. Step 2: Check required connection details

   FTP requires host, username, and password. 'ftp' => [ 'driver' => 'ftp', 'host' => env('FTP_HOST'), 'username' => env('FTP_USERNAME'), 'password' => env('FTP_PASSWORD') ], includes these minimal required keys.

3. Final Answer:

   'ftp' => [ 'driver' => 'ftp', 'host' => env('FTP_HOST'), 'username' => env('FTP_USERNAME'), 'password' => env('FTP_PASSWORD') ], -> Option D

4. Quick Check:

   FTP driver + host, username, password needed [OK]

Hint: FTP disk needs driver 'ftp' and host, user, password [OK]

Common Mistakes:

• Using wrong driver like 'local' or 's3' for FTP
• Missing required host or credentials
• Confusing bucket with FTP config
