Blade Helpers

A collection of Blade Directive to speed up tasks that are common in Blade templates

Installation

1. Move the two included php files in to /app/Providers/.
2. In /config/app.php add

        /**
         * Custom Service Providers
         */
        App\Providers\BladeDirectiveProvider::class,
        App\Providers\BladeIfDirectiveProvider::class,

3. The above will enable the directives in your Blade templates.

Since Blade tags get compiled into normal PHP inside your template you are REQUIRED to clear your compiled views via a php artisan view:clear call!

Usage

Blade Helper Directives

*A Blade directive is just a shorter syntax to generate markup.

asset

*The @asset directive provides chache busting functionality by appending the Unix timestamp value of the files modified timestamp

<link href="@asset('/css/app.css')" rel="stylesheet">

The above markup produces...

<link href="/css/app.css?v=1506526109" rel="stylesheet">

This effectively eliminates unwanted caching since any time app.css is deployed the files modified timestamp will get updated and consequently change the v= value in the url for the css file.

A CSS example is shown above, but this can be used for ANY local file you wish to have cache busting enabled on

icon

The @icon directive allows you to generate the full syntax for a simple icon (more complex icons i.e. layered, rotating, etc will still need to be written out). Font-awesome is the assumed font library.

In its simplest form you just pass the name of the icon.

<a href="#/">@icon('envelope')Messages</a>
<!-- Produces -->
<!-- <a href="#"><i class="fa fa-envelope"></i></a> -->

You can also pass two additinal parameters. The second parameter is the $provider so an example would be glyphicon. This should be the class that gets added to the element. The third parameter you can use the the tag type (i, span, etc). If you need access to the third tag you are required to pass the second!

A full example of this would be...

<a href="#">@icon('envelope', 'glyphicon', 'span') Messages</a>
<!-- Produces -->
<!-- <a href="#"><span class="glyphicon glyphicon-envelope"></span></a> -->

Blade If Directives

Blade "If" directives allow you to shorthand an if statment that you'd normally have to write out. These inherently have an else block available

hasPermission

The has permission directive allows you to wrap markup that you only want displayed if a user has a given permission. Can be used in place of the @can directive.

@hasPermission('manage-users')
    <li><a href="...">Manage Users</a></li>
@else
    <!-- Alternate link if they can't manage users -->
@endhasPermission
...

isInRole

Checks that the user is in a given Role

...
@isInRole('admin')
    <li><a href="...">Manage Users</a></li>
@else
    <!-- Alternate link if they can't manage users -->
@endisInRole
...

isActive

This is used to see if a link is currently the active link

<a href="#" @isActive('/')class="active"@endisActive>Home</a>

This directive calls the Request::is(...) function internally so you can pass any string to check that would work there. i.e. @isActive('users*) would match /users as wells /users/manage/1

As with all if directives there is an else block available. i.e. <a href="/users" class="@isActive('users')active @else muted@endisActive>Users</a>
