Laravel Application Helper Function: back
The back helper function in Laravel creates a redirect response to the user's previous location. It takes two optional parameters to control the status code and headers of the response. You can change the status code to be either "Found" or "Moved Permanently" and you can supply additional headers. There are different ways to return a redirect response using the Redirect facade, the response helper function, or the back helper function itself. You can also change the status code or supply additional headers as needed.
Laravel Application Helper Function: dispatch
The dispatch helper function allows you to easily push a new job onto the job queue. It resolves the Dispatcher instance from the Service Container and calls the dispatch method. You can also use app(Dispatcher::class)->dispatch($job) or Bus::dispatch($job) as alternatives to the helper function.
Laravel Application Helper Function: event
The event helper is a useful function for dispatching events and notifying their listeners. It allows you to pass a payload of data when dispatching the event, and the responses from the listeners are stored in an array. By setting the $halt parameter to true, the dispatcher will stop calling listeners after a non-null response is received. You can fire an event by specifying the class name or by instantiating a new instance of the event class itself. If no payload is supplied, the event instance itself will be used as the payload.
Laravel Application Helper Function: factory
The factory() function is used to create Eloquent models, primarily for testing applications. This method allows you to generate one or more instances of a specific model, with the option to apply modifications previously defined using the bind method. Example uses include returning a single instance of a user model, returning multiple instances, or applying modifications bound to a specific description like 'admin'.
Laravel Application Helper Function: method_field
The method_field helper function in Laravel returns an instance of Illuminate\Support\HtmlString containing a hidden HTML input field. This field has the name _method and a value passed as an argument to the function. See examples with different methods: PUT, POST, GET, PATCH, DELETE. The return value is an HtmlString instance, corresponding to an HTML hidden input field.
Laravel Application Helper Function: redirect
The redirect helper function in Laravel is used to redirect users to different URLs. When the $to parameter is set to null, the function returns an instance of the Illuminate\Routing\Redirector class. You can use the redirect function to access various methods of the Redirector, such as back(), home(), and to('/'), to control user flow in your application. If you provide a URL as the $to parameter, the redirect function internally calls the to method on the Redirector instance. You can also generate secure (HTTPS) URLs by setting the $secure parameter to true. Additionally, you can change the HTTP status code and supply additional headers by providing arguments for the $status and $headers parameters, respectively.
Laravel Application Helper Function: request
The request helper function in Laravel is used to retrieve data from the user's input. To retrieve an instance of Illuminate\Http\Request, call the request method without any arguments. To retrieve an input value, provide at least the $key argument. You can also use the request function as a shortcut to the Request::input method. It can be used to retrieve a subset of the user's input data or to retrieve input with a default value if no input is found.
Laravel Application Helper Function: validator
Learn how to use the validator helper function in Laravel to validate input data. The validator function is a versatile helper function that can be used with or without arguments. When used without arguments, it returns an instance of Illuminate\Contracts\Validation\Factory that provides access to validation methods. You can also use the validator function with arguments to directly call the make method on the factory instance.
Laravel Application Helper Function: view
The view function in Laravel can be used to return a view instance or a view factory. When called without arguments, it returns the view factory. When called with arguments, it creates a view instance based on the provided view file name, initial data, and additional data to be merged. The provided data can be an array or an object that implements the Arrayable interface. To render a view to a string, you can use the render method on the view instance.
Laravel Application Helper: old
The old helper function is used to retrieve an old input item from a previous request. It accepts a $key argument that should be the name of the input item to retrieve. A $default value can also be supplied to be returned if the given $key does not exist. There are alternative methods to achieve the same result, such as using the Input facade or the request() helper function.
