Loop over and include Blade views simultaneously using @each in Laravel
Sometimes, there comes a scenario where you want to loop over a collection or array and include Blade views based on the iteration of that collection/array. You can use @foreach and @include for this purpose but there’s a handy way using which you can simplify this process.
The @each directive
Laravel provides an @each directives in which you can pass in a Blade view and a collection/array and it will handle including the view on each iteration automagically.
So, for instance, let’s say, you have an array called $books like so.
$books = [
'Angry River',
'Harry Potter',
'Deep Work'
];
And you want to loop over this array and simultaneously render a view called resources/views/books.blade.php with the following content…
// This will be called on each iteration of `$books`
<li>{{ $key }} - {{$book}}</li>
…inside another view on each iteration, you can do it using @each directive like so.
<ul class="list-disc">
@each('books', $books, 'book')
</ul>
As you can tell, the @each directive accepts three arguments.
- The first argument is the view partial (
resources/views/books.blade.php) to render for each element in the array or collection. - The second argument is the array (
$books) or collection you wish to iterate over. - The third argument is the variable name (
$bookinbooks.blade.php) that will be assigned to the current iteration within the view.
The iteration key is available in the form of the $key variable.
The example above will render the HTML something like this.
<ul class="list-disc">
<li>0 - Angry River</li>
<li>1 - Harry Potter</li>
<li>2 - Deep Work</li>
</ul>
Note: Views rendered via
@eachdo not inherit the variables from the parent view. If the child view requires these variables, you should use@foreachand@includeinstead.
Default view
The @each accepts an optional fourth argument which is a default view if in any case the collection/array is empty like so.
@each('books', $books, 'book', 'nobooks')
Here, nobooks is the resources/views/nobooks.blade.php Blade view which will be rendered when $books is empty.
You can play around with this example live at Laravel Playground below.
