Laravel 5.1 @can, how use OR clause

Question

I did not find how to use a clause (OR, AND) in view with @can, for checking multiple abilities ...

I tried:

@can(['permission1', 'permission2']) 
@can('permission1' or 'permission2')
@can('permission1' || 'permission2')

But dont work ;(

Solution 1

You can use the Gate facade:

@if(Gate::check('permission1') || Gate::check('permission2'))

@endif

Solution 2

The @canany blade directive has been added to Laravel v.5.6.23 on May 24, 2018

Usage:

@canany(['edit posts', 'delete posts'])
    <div class="actions">
        @can('edit posts')
            <button>Edit post</button>
        @endcan
        @can('delete posts')
            <button>Delete post</button>
        @endcan
    </div>
@endcanany

Solution 3

I've added this directive in my Laravel 5.4 app that allows me to use a new @canany('write|delete') directive in my blade views.

// AppServiceProvider.php@boot()

Blade::directive('canany', function ($arguments) {
    list($permissions, $guard) = explode(',', $arguments.',');

    $permissions = explode('|', str_replace('\'', '', $permissions));

    $expression = "<?php if(auth({$guard})->check() && ( false";
    foreach ($permissions as $permission) {
        $expression .= " || auth({$guard})->user()->can('{$permission}')";
    }

    return $expression . ")): ?>";
});

Blade::directive('endcanany', function () {
    return '<?php endif; ?>';
});

Example in blade view:

@canany('write|create')
    ...
@endcanany

Here's the doc for extending Blade on 5.4

Solution 4

You can call @can multiple times.

@if( @can('permission1') || @can('permission2') )

@if( Gate::check('permission1') || Gate::check('permission2') )

Solution 5

Use can method on Authenticated User,

@if ( Auth::user()->can('permission1', App\Model::class) || Auth::user()->can('permission2',  App\Model::class) )

@endif

@Marcaum54 What about it doesn't work? Does it give an error?

[Marcaum54]

Follow error: FatalErrorException in /.../0681985e98a64fda6c3db7d157508293 line 53: Call to undefined function can() when generating the view he returned this: <?php if( @can('inscricoes') || @can('inscricoes-opec') ): ?>

This compiles to <?php if(@can('permission1') || @can('permission2')): ?>. Note that @can() is a valid function call (the at-symbol suppresses warnings), but the can() method does not exist.

Is there difference from @can and this way? in this case, wich?

[titleistfour]

Very nice! This should be in Laravel core.

Do you know if @ canany supports passing the policy model? For example with @ can you can do @ can('edit', 'App\Post').

[Clément Baconnier]

@ScottSalisbury you can use e.g. @canany(['post.update', 'post.create'], [$post]) But it's not ideal since it's the same argument for both policies. I would recommend to make your own directive for the example I provided.
