Laravel Routing

# Basic Routing

Route::get('/page', function() {
    return view('page'); 
   // get is the request method, it may be get, post, put, patch, delete  
   // view is helper function  
   // page is the blade template file i.e page.blade.php

In above example, view helper function retrieves a view instance i.e page is the view blade template file.

open a route file i.e route.php inside routes directory and paste the above code.

<!DOCTYPE html>
<html lang="en">
<meta charset="utf-8">
<title>Laravel Basic Routing</title>
      <h1><center>Laravel Basic Routing</center></h1>

create a file page.blade.php save it to your resources/views/ directory:

To try basic routing, visit your site using a URL similar to this one:

Route::get('product/{id}', function($id) {
    echo 'Product Id: '. $id;
Route::get('product/{id?}', function($id = 0) {
    echo 'Product Id: '. $id;

# Regular Expression

Route::get('user/{name}', function($name) {
    // executed if {name} is alphabetic characters ;
})->where('name', ['A-Za-z]+');
Route::get('user/{id}', function($id) {
     // executed if {id} is numeric 
})->where('id', ['0-9]+');
Route::get('user/{id}/{name}', function($id, $name) {
     // executed if {id} is numeric and {name} is alphabetic characters
})->where(['id' => '[0-9]+', 'name' => '[a-z]+']);

# Global Constraints

If we want the id parameter in all route should be integer, so we need to define it as a global constraint. we'll use pattern method to define global constraint under app/Providers/RouteServiceProvider.php

public function boot() 
      Route::pattern('id', '[0-9]+');

Once the pattern has been defined, it is automatically applied to all routes.

# Redirect Routes

If we want to redirect a url to another url, we can use Route::redirect('/from', '/to');

we want to redirect a url to another url withs status code, we can pass status code as a third parameter. we can use Route::redirect('/from', '/to', 301); where 301 is status code and 301 is used for permanent redirection.

For permanent redirection, We can use Route::permanentRedirect('/from', '/to'); as well

# Named Routes

We can specify a name for a route by chaining the name method onto the route definition:

Route::get('user/profile', 'UserController@showProfile')->name('profile');

# Accessing The Current Route

To understand the accessing the current route, we'll use the routing of named route

$route = Route::current();
$route = Route::currentRouteName();
$route = Route::currentRouteAction();
