Detect 'false' with laravel @forelse and stop looping
Tag : php , By : General Mills

hop of those help? I have a loop which sometimes has no data. I'm trying to prevent the looping of data if the array item is empty/false etc. , Why don't you just check it before you try to loop through it?
@if(!empty($section['menu_items']))
    @foreach($section['menu_items'] as $menu_item)
        MENU ITEMS
    @endforeach
@else
    {{ -- No menu items available --}}
@endif

is forelse remove in laravel 4.2.4?

will be helpful for those in need I don't think @forelse has been around since Laravel 3. I could be wrong. I know it was removed at some point though. You need to use a standard @if and @foreach now.
@if (empty($result))
  <tr><td>No name match</td></tr>
@else
  @foreach ($result as $data)
    <tr><td> $data->name </td></tr>
  @endforeach
@endif

Difference between foreach and forelse in Laravel

This might help you I believe the answer to your question is that, essentially, ForElse is a ForEach loop, but with extra handling for empty input(s).
From the Laravel 5 docs on Blade Templates, an example illustrating both loops with the same list of Users as Input:
@foreach ($users as $user)
    <p>This is user {{ $user->id }}</p>
@endforeach

@forelse ($users as $user)
    <li>{{ $user->name }}</li>
@empty
    <p>No users</p>
@endforelse
   /**
     * Compile the for-each statements into valid PHP.
     *
     * @param  string  $expression
     * @return string
     */
    protected function compileForeach($expression)
    {
        preg_match('/\( *(.*) +as *(.*)\)$/is', $expression, $matches);

        $iteratee = trim($matches[1]);

        $iteration = trim($matches[2]);

        $initLoop = "\$__currentLoopData = {$iteratee}; \$__env->addLoop(\$__currentLoopData);";

        $iterateLoop = '$__env->incrementLoopIndices(); $loop = $__env->getLastLoop();';

        return "<?php {$initLoop} foreach(\$__currentLoopData as {$iteration}): {$iterateLoop} ?>";
    }


   /**
     * Compile the for-else statements into valid PHP.
     *
     * @param  string  $expression
     * @return string
     */
    protected function compileForelse($expression)
    {
        $empty = '$__empty_'.++$this->forElseCounter;

        preg_match('/\( *(.*) +as *(.*)\)$/is', $expression, $matches);

        $iteratee = trim($matches[1]);

        $iteration = trim($matches[2]);

        $initLoop = "\$__currentLoopData = {$iteratee}; \$__env->addLoop(\$__currentLoopData);";

        $iterateLoop = '$__env->incrementLoopIndices(); $loop = $__env->getLastLoop();';

        return "<?php {$empty} = true; {$initLoop} foreach(\$__currentLoopData as {$iteration}): {$iterateLoop} {$empty} = false; ?>";
    }

laravel blade append to @section in @forelse


Tag : laravel , By : bdurbin

To fix this issue My main template blade has a @yield('section_name') in the tag to append css/ js. Now I have a forelse like this: , Use @append instead of @endsection
@forelse($collection as $item)
    some text
    @section('section_name')
        // link to stylesheet
    @append
@empty
 // something went wrong
@endforelse

Laravel @foreach and @forelse


Tag : laravel , By : sadboy

To fix this issue I have a problem with my view of laravel. I have a field that executes a loop, and if it has data in the field it list, but if it does not it only shows me nothing. , KISS and just use @if / @else:
<em>{{ $prices->price ?? ' - ' }}</em> <br>

@if($prices && $prices->infos_home)
    @foreach($prices->infos_home as $info)
        <em>{{ $info }}</em> <br>
    @endforeach
@else
    <em> - </em>
@endif

Access relation in forelse on the same model - laravel

This might help you To eager load a distant relationship you can use the dot notation like so:
$category = Category::with('translation', 'childCategories.translations')
    ->active()
    ->where('id', $id)
    ->first();
