Laravel blade check empty foreach
PhpLaravelForeachPhp Problem Overview
I want to check if my foreach is empty so the basic html markup isn't displayed with no results inside. I'm trying to wrap it in an if statement and then if it is empty do nothing else loop the foreach.
@if ($status->replies === '')
@elseif
<div class="media-body reply-body">
@foreach ($status->replies as $reply)
<p>{{ $reply->body }}</p>
@endforeach
</div>
@endif
@if (!(empty($status->replies))
<div class="media-body reply-body">
@foreach ($status->replies as $reply)
<div class="media">
<a class="pull-left" href="{{ route('profile.index', ['username' => $reply->user->username]) }}">
<img class="media-object" alt="{{ $reply->user->getNameOrUsername() }}" src="{{ $reply->user->getAvatarUrl() }}">
</a>
<div class="media-body">
<h5 class="media-heading"><a href="{{ route('profile.index', ['username' => $reply->user->username]) }}">{{ $reply->user->getNameOrUsername() }}</a></h5>
<p>{{ $reply->body }}</p>
<ul class="list-inline list-replies">
<li>
<a href="{{ route('status.like', ['statusId' => $reply->id]) }}"><i class="fa fa-thumbs-up"></i></a>
{{ $reply->likes->count() }} {{ str_plural('like', $reply->likes->count()) }}</li>
<li>{{ $reply->created_at->diffForHumans() }}</li>
</ul>
</div>
<hr>
</div>
@endforeach
</div>
@endif
Php Solutions
Solution 1 - Php
Check the documentation for the best result:
@forelse($status->replies as $reply)
<p>{{ $reply->body }}</p>
@empty
<p>No replies</p>
@endforelse
Solution 2 - Php
I think you are trying to check whether the array is empty or not.You can do like this :
@if(!$result->isEmpty())
// $result is not empty
@else
// $result is empty
@endif
Reference isEmpty()
Solution 3 - Php
You should use empty()
@if (!empty($status->replies))
<div class="media-body reply-body">
@foreach ($status->replies as $reply)
<p>{{ $reply->body }}</p>
@endforeach
</div>
@endif
You can use count, but if the array is larger it takes longer, if you only need to know if its empty, empty is the better one to use.
Solution 4 - Php
It's an array, so ==== '' won't work (the === means it has to be an empty string.)
Use count() to identify the array has any elements (count returns a number, 1 or greater will evaluate to true, 0 = false.)
@if (count($status->replies) > 0)
// your HTML + foreach loop
@endif
Solution 5 - Php
> ###Echoing Data If It Exists > Sometimes you may wish to echo a variable, but you aren't sure if the variable has been set. We can express this in verbose PHP code like so: > {{ isset($name) ? $name : 'Default' }} > However, instead of writing a ternary statement, Blade provides you with the following convenient short-cut: > {{ $name or 'Default' }} > In this example, if the $name variable exists, its value will be displayed. However, if it does not exist, the word Default will be displayed.
Solution 6 - Php
Using following code, one can first check variable is set or not using @isset of laravel directive and then check that array is blank or not using @unless of laravel directive
@if(@isset($names))
@unless($names)
Array has no value
@else
Array has value
@foreach($names as $name)
{{$name}}
@endforeach
@endunless
@else
Not defined
@endif
Solution 7 - Php
This is my best solution if I understood the question well:
Use of $object->first() method to run the code inside if statement once, that is when on the first loop. The same concept is true with $object->last().
@if($object->first())
<div class="panel user-list">
<table id="myCustomTable" class="table table-hover">
<thead>
<tr>
<th class="col-email">Email</th>
</tr>
</thead>
<tbody>
@endif
@foreach ($object as $data)
<tr class="gradeX">
<td class="col-name"><strong>{{ $data->email }}</strong></td>
</tr>
@endforeach
@if($object->last())
</tbody>
</table>
</div>
@endif
