Control flow

Control flow decides what a view renders. It uses the same directives as Blade: @if, @foreach and @forelse, each closed by its own end directive.

@if, @elseif and @else

The first true branch renders, and the rest are skipped. The condition is a field of the context. A value is false when it is null, false, zero, an empty string, or an empty list. A struct is true.

@if ($is_admin)
  <p>Admin</p>
@elseif ($is_member)
  <p>Member</p>
@else
  <p>Guest</p>
@endif

Live example

Member

@foreach

Repeats the body for each item. Inside the loop, the loop variable (here tag) holds the current item.

@foreach (tag in tags)
  <li>{{ $tag }}</li>
@endforeach

Live example

• rust
• rocket
• propel

@forelse and @empty

Like @foreach, but it renders the @empty branch when the list has no items. A null list counts as empty.

@forelse (item in items)
  <li>{{ $item }}</li>
@empty
  <li>Nothing here yet.</li>
@endforelse

Live example, with an empty list

• Nothing here yet.

Optional values

Reading a field of a null value is an error, as in Blade. Check an optional value with @if first. A null value at the end of a path, such as $author on its own, prints nothing.

@if ($author)
  <p>Author: {{ $author.name }}</p>
@else
  <p>No author yet.</p>
@endif

Live example, with no author

No author yet.
