💡 Hint

Common Mistakes

Using @endforeach which ends a loop

Using @stop or @endsection which end sections

The @endif directive closes an @if block in Blade templates.

3fill in blank

hard

💡 Hint

Common Mistakes

Using plural variable names inside the loop

Omitting the $ sign in the variable

The variable inside the loop should be a singular form with the $ sign inside the parentheses. In Blade you keep the $ sign for variables.

4fill in blank

hard

Fill both blanks to display a variable safely and end the section.

Laravel

@section('content')
    [1]
@[2]

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

A$title

B$content

Cstop

Dendsection

Attempts:

3 left

💡 Hint

Common Mistakes

Using raw PHP tags instead of Blade syntax

Confusing @stop and @endsection

Use {{ $title }} to display the variable safely. @stop ends the section and is an alternative to @endsection.

5fill in blank

hard

Fill all three blanks to create a Blade component with a slot and pass a variable.

Laravel

<x-alert type="[1]">
    [2]
        [3]
    @endslot
</x-alert>

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

Aerror

B{{ $message }}

C@slot('title')

Dsuccess

Attempts:

3 left

💡 Hint

Common Mistakes

Using incorrect slot syntax

Forgetting to pass the variable inside curly braces

The component type is set to 'error'. Use @slot('title') to define a slot, and {{ $message }} to display the message inside the component.

Practice

1. Which Blade directive is used to display a variable safely escaped in a Laravel view?

easy

A. @foreach($variable as $item)

B. @php $variable @endphp

C. {{ $variable }}

D. @if($variable)

Solution

1. Step 1: Understand Blade variable display

   Blade uses double curly braces {{ }} to safely display variables with HTML escaping.

2. Step 2: Identify correct directive for safe output

   The {{ $variable }} syntax outputs the variable safely, preventing XSS attacks.

3. Final Answer:

   {{ $variable }} -> Option C

4. Quick Check:

   Safe variable display = {{ $variable }} [OK]

Hint: Use double curly braces {{ }} for safe variable output [OK]

Common Mistakes:

• Using @php for output instead of {{ }}
• Confusing @if with variable display
• Using @foreach for single variable output

2. Which of the following is the correct syntax to start a Blade loop over an array $items?

easy

A. @loop($items as $item)

B. @for($items as $item)

C. @while($items as $item)

D. @foreach($items as $item)

Solution

1. Step 1: Recall Blade loop directives

   Blade uses @foreach to loop over arrays or collections.

2. Step 2: Match correct syntax

   The correct syntax is @foreach($items as $item), which loops through each item.

3. Final Answer:

   @foreach($items as $item) -> Option D

4. Quick Check:

   Loop over array = @foreach [OK]

Hint: Use @foreach for looping arrays in Blade [OK]

Common Mistakes:

• Using @loop which does not exist
• Using @for incorrectly for arrays
• Using @while for array loops

3. What will be the output of this Blade snippet if $count = 3?

@if($count > 5)
  Large
@elseif($count > 1)
  Medium
@else
  Small
@endif

medium

A. Large

B. Medium

C. Small

D. No output

Solution

1. Step 1: Evaluate the condition $count > 5

   Since $count = 3, 3 > 5 is false, so skip the first block.

2. Step 2: Evaluate the @elseif($count > 1) condition

   3 > 1 is true, so Blade outputs "Medium" and skips the @else.

3. Final Answer:

   Medium -> Option B

4. Quick Check:

   3 > 1 but not > 5 = Medium [OK]

Hint: Check conditions top to bottom; first true block runs [OK]

Common Mistakes:

• Choosing Large because 3 is close to 5
• Ignoring @elseif and picking @else
• Thinking all blocks output

4. Identify the error in this Blade snippet:

@foreach($users as $user)
  
{{ $user->name }}
@endforeach
@endfor

medium

A. Incorrect closing directive @endfor instead of @endforeach

B. Missing closing @endforeach directive

C. Incorrect variable name $user instead of $users

D. Missing opening @for directive

Solution

1. Step 1: Check loop opening and closing directives

   The loop starts with @foreach but incorrectly ends with @endfor.

2. Step 2: Match correct closing directive

   Blade requires @endforeach to close a @foreach loop, so @endfor is invalid here.

3. Final Answer:

   Incorrect closing directive @endfor instead of @endforeach -> Option A

4. Quick Check:

   Match @foreach with @endforeach [OK]

Hint: Close @foreach with @endforeach, not @endfor [OK]

Common Mistakes:

• Using @endfor to close @foreach
• Confusing $user and $users variables
• Missing closing directive entirely

5. You want to include a Blade template named header.blade.php inside your main view. Which directive correctly includes it and passes a variable $title with value 'Welcome'?

hard

A. @include('header', ['title' => 'Welcome'])

B. @include('header', $title = 'Welcome')

C. @include('header', ['title' => Welcome])

D. @include('header', title = 'Welcome')

Solution

1. Step 1: Recall correct syntax for @include with data

   Blade's @include accepts the view name and an associative array of data.

2. Step 2: Check array syntax for passing variables

   The correct way is @include('header', ['title' => 'Welcome']) with quotes around string values.

3. Final Answer:

   @include('header', ['title' => 'Welcome']) -> Option A

4. Quick Check:

   Pass variables as array in @include [OK]

Hint: Pass variables as array in @include(['key' => value]) [OK]

Common Mistakes:

• Passing variable without array brackets
• Missing quotes around string values
• Using assignment syntax inside @include
