💡 Hint

Common Mistakes

Using 'controller' instead of 'mailable' will create a controller, not an email class.

Using 'model' or 'middleware' creates unrelated classes.

Use make:mailable to generate a new mailable class in Laravel.

Complete the code to send the mailable class named WelcomeEmail to a user.

Laravel

Mail::to($user->email)->[1](new WelcomeEmail());

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

💡 Hint

Common Mistakes

Using 'queue' sends the email later, not immediately.

Using 'make' or 'create' are not valid methods for sending emails.

The send method sends the email immediately.

Fix the error in the build method to return the email view named 'emails.welcome'.

Laravel

public function build()
{
    return $this->[1]('emails.welcome');
}

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

Brender

Cview

Dmake

Attempts:

💡 Hint

Common Mistakes

Using 'send' causes an error because it's not a method of the mailable class.

Using 'render' returns the HTML but does not set the email view.

The build method must return $this->view('view.name') to set the email template.

4fill in blank

hard

Fill both blanks to pass data to the email view in the build method.

Laravel

public function build()
{
    return $this->view('emails.notification')->with([1] => [2]);
}

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

A'userName'

B$this->userName

C'email'

D$this->email

💡 Hint

Common Mistakes

Using variable names without quotes for the key causes errors.

Passing wrong property names that don't exist in the class.

Use with('key' => value) to pass data to the view. Here, 'userName' is the key and $this->userName is the value.

5fill in blank

hard

Fill all three blanks to define a constructor that accepts a User object and assigns it to a class property.

Laravel

public function __construct([1] $user)
{
    $this->[2] = [3];
}

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

Buser

C$user

DUserData

💡 Hint

Common Mistakes

Using wrong class names or variable names.

Forgetting the dollar sign in the parameter variable.

The constructor receives a User object named $user and assigns it to the property $this->user.

Practice

1. What is the main purpose of a Mailable class in Laravel?

easy

A. To organize email content and settings in one place

B. To handle database migrations

C. To manage user authentication

D. To define API routes

Solution

1. Step 1: Understand the role of Mailable classes

   Mailable classes are designed to organize email content and settings such as subject, recipients, and views.

2. Step 2: Compare with other Laravel features

   Database migrations, authentication, and routing are handled by other parts of Laravel, not Mailable classes.

3. Final Answer:

   To organize email content and settings in one place -> Option A

4. Quick Check:

   Mailable class purpose = Organize email content [OK]

Hint: Mailable classes bundle email setup and content [OK]

Common Mistakes:

• Confusing Mailable with database or routing features
• Thinking Mailable handles user login
• Assuming Mailable manages API endpoints

2. Which method must you define inside a Laravel Mailable class to set the email's view and subject?

easy

A. send()

B. compose()

C. build()

D. render()

Solution

1. Step 1: Recall Mailable class structure

   The build() method is where you define the email's view and subject in Laravel Mailable classes.

2. Step 2: Eliminate incorrect methods

   Methods like send(), compose(), and render() are not used in Laravel Mailable classes for this purpose.

3. Final Answer:

   build() -> Option C

4. Quick Check:

   Set email view and subject = build() method [OK]

Hint: Use build() to configure email content and subject [OK]

Common Mistakes:

• Using send() instead of build()
• Confusing build() with render()
• Trying to use compose() which is not a Laravel Mailable method

3. Given this Mailable class snippet, what will be the subject of the sent email?

class OrderShipped extends Mailable {
  public function build() {
    return $this->subject('Your order has shipped')->view('emails.shipped');
  }
}

medium

A. Your order has shipped

B. emails.shipped

C. OrderShipped

D. No subject set

Solution

1. Step 1: Analyze the build() method

   The build() method sets the subject using subject('Your order has shipped').

2. Step 2: Understand what the subject() method does

   This method sets the email's subject line to the given string.

3. Final Answer:

   Your order has shipped -> Option A

4. Quick Check:

   Email subject = 'Your order has shipped' [OK]

Hint: Subject is set by subject() inside build() [OK]

Common Mistakes:

• Confusing view name with subject
• Assuming class name is subject
• Thinking no subject is set without explicit call

4. Identify the error in this Mailable class code:

class WelcomeUser extends Mailable {
  public $user;

  public function __construct($user) {
    $this->user = $user;
  }

  public function build() {
    return $this->view('emails.welcome')->with('user');
  }
}

medium

A. Wrong method name instead of build()

B. Incorrect property declaration

C. Missing return statement in constructor

D. Missing argument in with() method

Solution

1. Step 1: Check the with() method usage

   The with() method requires a key-value pair or an array to pass data to the view, but here it only has a key string without a value.

2. Step 2: Verify other parts of the class

   Property declaration and constructor are correct, and the method name build() is correct.

3. Final Answer:

   Missing argument in with() method -> Option D

4. Quick Check:

   with() needs key and value [OK]

Hint: with() needs key and value to pass data [OK]

Common Mistakes:

• Passing only key without value to with()
• Forgetting to return in build()
• Misnaming build() method

5. You want to send an email with a Mailable class that passes a user's name and order ID to the view. Which is the correct way to pass this data inside the build() method?

hard

A. return $this->view('emails.order')->with('name', $this->name, 'orderId', $this->orderId);

B. return $this->view('emails.order')->with(['name' => $this->name, 'orderId' => $this->orderId]);

C. return $this->view('emails.order')->with('name', $this->name)->with('orderId');

D. return $this->view('emails.order')->with(['name', $this->name, 'orderId', $this->orderId]);

Solution

1. Step 1: Understand how to pass multiple data items

   The with() method accepts an associative array to pass multiple variables to the view.

2. Step 2: Analyze each option's syntax

   return $this->view('emails.order')->with(['name' => $this->name, 'orderId' => $this->orderId]); correctly uses an array with keys and values. return $this->view('emails.order')->with('name', $this->name)->with('orderId'); misses value for 'orderId'. return $this->view('emails.order')->with('name', $this->name, 'orderId', $this->orderId); passes too many arguments. return $this->view('emails.order')->with(['name', $this->name, 'orderId', $this->orderId]); uses a numeric array instead of associative.

3. Final Answer:

   return $this->view('emails.order')->with(['name' => $this->name, 'orderId' => $this->orderId]); -> Option B

4. Quick Check:

   Pass multiple data as associative array in with() [OK]

Hint: Use associative array in with() for multiple data [OK]

Common Mistakes:

• Passing multiple arguments instead of one array
• Omitting values for keys in with()
• Using numeric array instead of associative
