Forelse Without Empty

[ryangurn]

I have been switching most of my code over to using @forelse (finally, took a while to realize this existed).

I realized that the @forelse directive requires that you use an @empty tag to work without erroring.

There are many times in which @forelse would be useful without an @empty tag.

An example of this is that you want to verify that a collection is not empty but if it is empty, there is nothing displayed.

Using the @forelse in this way would reduce the amount of extra blade directive in quite a large way.

The below example shows the current method versus the current method with @forelse as well as the functionality I am requesting.

{{-- current solution with @if & @foreach directives to ensure a collection is non empty before looping --}}
@if(!$collection->isEmpty())
    @foreach($collection as $collect)
        {{-- do something --}}
    @endforeach
@endif

{{-- current solution with @forelse directives to ensure a collection is non empty before looping --}}
@forelse($collection as $collect)
    {{-- do something --}}
@empty
@endforelse

{{-- requested functionality with @forelse directives to ensure a collection is non empty before looping --}}
@forelse($collection as $collect)
    {{-- do something --}}
@endforelse

Let me know what you think, I could be misunderstanding the use of the @forelse directive but it seems that including an @empty directive with nothing to show is a bit useless.

Its quite possible that there is a better way too!

Hi there ✋🏻 .

TLDR:
Use @forelse if you want an elegant way to handle empty states using Blade.
Use @foreach for regular loop statements.

Kind of...

The idea of the @foresle is to add an elegant way to handle empty states using Blade.

e.g. This displays a message when the posts collections is empty

@forelse ($posts as $post)
    {{ $post->title }}
@empty
    ¡There are not posts!
@endforelse

If you don't want to display any message when the when the posts collections is empty, you can use the regular @foreach blade statement.
e.g.

@foreach ($posts as $post)
    {{ $post->title }}
@endforeach

hm, I see.

The issue that arises is that in most cases when I just use @forelse with say and empty collection. I just get errors.

Let me see if I can find an example of when this happens.

I cannot find an example that works. Thanks so much for your advice! It will greatly help me in making better decisions in the future between @forelse and @foreach.
