How to Set Variables in a Laravel Blade Template

How to Set Variables in a Laravel Blade Template

It is discouraged to do in a view so there is no blade tag for it.
If you do want to do this in your blade view, you can either just open a php tag as you wrote it or register a new blade tag. Just an example:

<?php
/**
 * <code>
 * {? $old_section = "whatever" ?}
 * </code>
 */
Blade::extend(function($value) {
    return preg_replace('/\{\?(.+)\?\}/', '<?php ${1} ?>', $value);
});

assign a value to a variable in blade file

@if($user_role=='2')
  @php $status='1'; @endphp
@endif

@if($user_role=='3')
  @php $status='2'; @endphp
@endif

@if($user_role=='4')
  @php $status='3'; @endphp
@endif

you can check the value by adding echo

 @if($user_role=='4')
  @php echo $status='3'; @endphp
@endif

laravel blade template variables

Assume due_at is a timestamp.

@foreach ($farmer->tasks as $task)
    @if (Carbon::parse($task->pivot->due_at) < Carbon::now())
        <?php $style = 'alert alert-danger'; ?>
    @elseif (Carbon::parse($task->pivot->due_at) > Carbon::now())
        <?php $style = 'alert alert-success'; ?>
    @else
        <?php $style = ''; ?>
    @endif
    <div class="list-group-item {{ $style }}">{{$task->name}} <span class="glyphicon glyphicon-calendar"> {{ $task->pivot->due_at }}</span> <span class="glyphicon glyphicon-pencil"></span><span class="glyphicon glyphicon-trash"></span></div>
@endforeach 

declaring simple variables in views in Laravel

The Blade {{ }} will echo out what you are doing.

You should do it like this:

<?php $a = 0; ?>
@foreach($fans as $fan)
        @foreach ($array as $x)
             @if ($fan->fbid == $x)
                 <?php $a++; ?>                  
             @endif
        @endforeach
@endforeach

{{$a}}

I agree with @Kiril Ivanov answer, but if you still want to do that you can use

@php ($variable = 'test')

How to set a variable in blade (laravel 5.3)?

You are using laravel-4 template comment syntax to define/set variables which is may be not working with L5.x.

But you can try @php ($p3 = $key['p3'])

OR

@php
$p3 = $key['p3']
@endphp

Above both are same.

Further you go with create own service provider like
1 create BladeServiceProvider:

<?php 
//app/Providers/BladeServiceProvider.php
namespace App\Providers;

use Illuminate\Support\ServiceProvider;

class BladeServiceProvider extends ServiceProvider
{
    public function boot()
    {
        /* @datetime($var) */
        \Blade::extend(function($view, $compiler)
        {
            $pattern = $compiler->createOpenMatcher('datetime');

            return preg_replace($pattern, '$1<?php echo $2->format(\'m/d/Y H:i\')); ?>', $view);
        });

        /* @eval($var++) */
        \Blade::extend(function($view)
        {
            return preg_replace('/\@eval\((.+)\)/', '<?php ${1}; ?>', $view);
        });
    }

    public function register()
    {
        //
    }
}

2 Register BladeServiceProvider:

<?php
//in config/app.php add
return [

    // ...

    'providers' => [

        // ...

        'App\Providers\BladeServiceProvider',

Clear complied artisan clear-compiled
Assign value to variable @datetime($updated_at)

OR

@eval($var = 1)
