Templating

Templating in WordPress should be delightful -- Mantle hopes to make it that way.

Views

WordPress template parts can be returned for a route.

Route::get( '/', function () {
return response()->view( 'template-parts/block', [ 'variable' => '123' ] );
} );

Blade Templates

Mantle also supports loading Laravel's Blade template parts. Blade and WordPress template parts can be used interchangeably. Mantle uses the illuminate/view package directly to provide complete compatibility with Blade templating.

Hello, {{ $name }}

View File Location

By default WordPress will only load a template part from the active theme and parent theme if applicable. Mantle supports loading views from a dynamic set of locations. Mantle support automatically register the current theme and parent theme as view locations. Additional paths can be registered through View_Loader.

View_Loader::add_path( '/path-to-add' );

View_Loader::remove_path( '/path-to-remove' );

Default View Locations

  • Active Theme
  • Parent of Active Theme
  • {root of mantle site}/views

Passing Variables to Views

Frequently you will need to pass variables down to views from controllers and routes. To ensure a global variable isn't overwritten the variables are stored in the helper method mantle_get_var().

// Call the view with a variable.
echo view( 'view/to/load', [ 'foo' => 'bar' ] );

// Inside the view...
echo mantle_get_var( 'foo' );

Inside of Blade Templates variables can access the variables directly. Blade will automatically escape the contents of a variable when using {{ ... }}.

Hello {{ $foo }}!

Passing Global Variables

Service Providers and other classes in the application can pass global variables to all views loaded. This can be very handy when you want to pass template variables to a service provider without doing any additional work in the route.

// Pass 'variable-to-pass' to all views.
View::share( 'variable-to-pass', 'value or reference to pass' );

Setting the Global Post Object.

Commonly views need to set the global post object in WordPress for a view. This will allow WordPress template tags such as the_ID() and the_title() to work properly.

Route::get( '/article/{article}', function ( App\Article $article ) {
// Supports passing a model, ID, or core WordPress object.
return View::make( 'template-parts/block', [ 'post' => $article ] )->set_post( $article );
} );

View Helpers

loop()

Loop over a collection/array of post objects. Supports a collection or array of WP_Post objects, Mantle Models, post IDs, or a WP_Query object. The post object will be automatically setup for each template part. We don't have to while ( have_posts() ) : the_post(); ... endwhile;, keeping our code nice and DRY.

$posts = Post::all();
echo loop( $posts, 'view-to-load' );

iterate()

Iterate over a collection/array of arbitrary data. Each view is passed index and item as a the current item in the loop.

echo iterate( [ 1, 2, 3 ], 'view-to-load' );

View Shortcuts

When inside of a partial, you can prefix your path slug with _ to load a sub-partial, appending everything after the _ to the current partial's file name (with a dash separating them).

// Inside of template-parts/homepage/slideshow.php.
view( '_slide', [ 'text' => 'Variable to Pass' ] );

// Inside of template-parts/homepage/slideshow-slide.php.
echo mantle_get_var( 'text', "Slide data!" );
