This tutorial is the end of this series. What we need to do is the detailed management function of Pages, Form Verification and deep use of namespaces, and a better notification component, and a simple big job is arranged.

1. Build Pages management functions

Run the following command:

Php artisan generate: controller admin/PagesController

Modify PagesController. php content:

<? Php
Namespace App \ Controllers \ Admin;
Use Page;
Use Input, Notification, Redirect, Sentry, Str;
Use App \ Services \ Validators \ PageValidator;
Class PagesController extends \ BaseController {
Public function index ()
{
Return \ View: make ('admin. pages. Index')-> with ('page', Page: all ());
}
Public function show ($ id)
{
Return \ View: make ('admin. pages. show ')-> with ('page', page: find ($ id)-> withAuthor (Sentry: findUserById (Page: find ($ id) -> user_id)-> name );
}
Public function create ()
{
Return \ View: make ('admin. pages. create ');
}
Public function store ()
{
$ Validation = new PageValidator;
If ($ validation-> passes ())
{
$ Page = new Page;
$ Page-> title = Input: get ('title ');
$ Page-> body = Input: get ('body ');
$ Page-> user_id = Sentry: getUser ()-> id;
$ Page-> save ();
Notification: success ('page added successfully! ');
Return Redirect: route ('admin. pages. edit', $ page-> id );
}
Return Redirect: back ()-> withInput ()-> withErrors ($ validation-> errors );
}
Public function edit ($ id)
{
Return \ View: make ('admin. pages. edit')-> with ('page', page: find ($ id ));
}
Public function update ($ id)
{
$ Validation = new PageValidator;
If ($ validation-> passes ())
{
$ Page = Page: find ($ id );
$ Page-> title = Input: get ('title ');
$ Page-> body = Input: get ('body ');
$ Page-> user_id = Sentry: getUser ()-> id;
$ Page-> save ();
Notification: success ('page updated successfully! ');
Return Redirect: route ('admin. pages. edit', $ page-> id );
}
Return Redirect: back ()-> withInput ()-> withErrors ($ validation-> errors );
}
Public function destroy ($ id)
{
$ Page = Page: find ($ id );
$ Page-> delete ();
Notification: success ('deleted successfully! ');
Return Redirect: route ('admin. pages. Index ');
}
}

Then, go to the: 8000/admin page and log on with the account password entered in the previous seed. We will get an error:

Class App \ Controllers \ Admin \ PagesController does not exist

This file already exists. Why does Laravel report an error ?! The reason is that in the second tutorial, I will talk about it here. Because this class is not in the top-level namespace, we didn't tell Laravel that we have added a new class in the sub-namespace. Let's tell it now:

Composer dump-autoload

OK, refresh, and we will get the following error:

View [admin. pages. index] not found.

Copy the entire pages folder in my view.

Refresh. You will get the following error:

Class 'notification' not found

This is because we have not installed this composer package, edvinaskrucas/notification. Please install version 3.0.1 On Your Own (4 is prepared for Laravel 5). This is the third small job. It must be placed in require. The package in require-dev is only used during development.

The Notification here is the better Notification component.

After packaging, run:

Composer dump-autoload

Add the following two lines in the appropriate position in config/app. php:

'Krucas \ Notification \ icationicationserviceprovider'
'Notification' => 'krucas \ Notification \ Facades \ notification'

The proper location many people do not understand, resulting in many people errors, the solution is also very simple: Please refer to my sample code: https://github.com/johnlui/Learn-Laravel-4/blob/master/app/config/app.php

Refresh. If you see the following interface:

Congratulations ~ Pages Management page complete!

2. Form Verification
