The cached Blade views may be removed using the view:clear Artisan command. Typically, this method should be called from the boot method of one of your application's service providers:Īfter updating the logic of a Blade directive, you will need to delete all of the cached Blade views. As you will see in the example below, the "namespace" will be prefixed to the component's name when the component is rendered. The anonymousComponentNamespace method accepts the "path" to the anonymous component location as its first argument and the "namespace" that components should be placed under as its second argument. To inform Laravel of this anonymous component location, you may use the anonymousComponentNamespace method provided by the Blade facade. However, you may occasionally want to register other anonymous component paths with Laravel in addition to the default path.įor example, when building a vacation booking application, you may wish to place flight booking related anonymous components within a resources/views/flights/bookings/components directory. Default values that are not explicitly passed to the parent component can not be accessed by the directive.Īs previously discussed, anonymous components are typically defined by placing a Blade template within your resources/views/components directory. The directive can not access parent data that is not explicitly passed to the parent component via HTML attributes. If the array element has a numeric key, it will always be included in the rendered class list: The directive accepts an array of classes where the array key contains the class or classes you wish to add, while the value is a boolean expression. The directive conditionally compiles a CSS class string. When in a nested loop, the parent's loop variable. Whether this is an odd iteration through the loop. Whether this is an even iteration through the loop. Whether this is the last iteration through the loop. Whether this is the first iteration through the loop. The total number of items in the array being iterated. The current loop iteration (starts at 1). The index of the current loop iteration (starts at 0). Of course, as mentioned in the documentation on views, data may be passed to the Blade view using the view helper's second $loop variable also contains a variety of other useful properties: Property blade.php file extension and are typically stored in the resources/views directory.īlade views may be returned from routes or controllers using the global view helper. In fact, all Blade templates are compiled into plain PHP code and cached until they are modified, meaning Blade adds essentially zero overhead to your application. Unlike some PHP templating engines, Blade does not restrict you from using plain PHP code in your templates. Let's rewrite the example of if….Blade is the simple, yet powerful templating engine that is included with Laravel. code to be executed if n doesn't match any constant code to be executed if n is equal to constant2 code to be executed if n is equal to constant1 The examples below will help us better understand the switch statements. But in the cases where your conditions are complicated like you need to check a condition with multiple constant values, a switch statement is preferred to an if.else. The switch statement is very similar to the if.else statement. Let's check if a mark entered is greater than or equal to 80. code to be executed when condition is true With the if statement your code only executes only when the condition is true. There are basically 4 different types of conditional statements in PHP, 1) The if statement Conditional statements are statements that can only be executed based on the fulfillment of a particular condition(s). While coding, you may get to a point where your results can only be gotten when a condition is valid.
