How to implement laravel_admin registration function

PHPzOriginal: 2023-04-12 09:12:40624browse

Laravel_admin is a background management system that separates the front and back ends. Implementing the registration function in Laravel_admin requires two aspects of front-end page design and back-end logic writing. This article will introduce the implementation process of these two aspects respectively.

1. Front-end interface implementation

To implement the registration function in Laravel_admin, you need to design a front-end page where users can fill in relevant information and submit it. First, create the register.blade.php file in the view layer to place the HTML code of the registration page. The code is as follows:

<!DOCTYPE html>
<html>
<head>
    <meta charset="utf-8">
    <title>Register page</title>
</head>
<body>
    <form method="post" action="{{ route(&#39;register&#39;) }}">
        {{ csrf_field() }}
        <label for="name">Username:</label>
        <input type="text" name="name" id="name"><br>
        <label for="email">Email:</label>
        <input type="email" name="email" id="email"><br>
        <label for="password">Password:</label>
        <input type="password" name="password" id="password"><br>
        <label for="password_confirmation">Confirm Password:</label>
        <input type="password" name="password_confirmation" id="password_confirmation"><br>
        <button type="submit">Submit</button>
    </form>
</body>

The above code is a basic registration form. Fields such as username, email, password, and password confirmation are provided in the form, and the route to which the form is submitted is specified through the route function provided by Laravel_admin. At the same time, in order to ensure data security, the csrf_field function provided by Laravel_admin is used in the form to generate a hidden _token form field.

2. Back-end logic writing

After the front-end page design is completed, the back-end logic program needs to be written, which involves the writing of the controller. In Laravel_admin, controller classes are generally stored in the app/Http/Controllers directory.

In the controller file, two methods need to be implemented: showRegistrationForm and register.

showRegistrationForm method

This method is used to render the registration form page, the code is as follows:

public function showRegistrationForm()
{
    return view('auth.register');
}

This method simply returns a view template, where The template name is auth.register. The view template corresponding to this template name is the register.blade.php file we defined earlier.

This method is used to process the data submitted by the form and store the data in the database. The code is as follows:

public function register(Request $request)
{
    $validator = Validator::make($request->all(), [
        'name' => 'required|string|max:255|unique:users',
        'email' => 'required|string|email|max:255|unique:users',
        'password' => 'required|string|min:6|confirmed',
    ]);

    if ($validator->fails()) {
        return redirect('register')
                    ->withErrors($validator)
                    ->withInput();
    }

    $this->create($request->all());

    return redirect('login');
}

protected function create(array $data)
{
    return User::create([
        'name' => $data['name'],
        'email' => $data['email'],
        'password' => bcrypt($data['password']),
    ]);
}

In this method, first use Laravel_admin's built-in validator Validator to verify the submitted data to ensure that there will be no duplicate user names or emails. If the verification fails, the error message and the form data submitted by the user (withInput()) are returned to the front-end page, prompting the user with the error message and filling back the form data to facilitate user modification.

If the verification is successful, the create method is called to store the user information in the database. In the create method, call the create method of laravel's built-in User model class to store fields such as username, email, and password in the database. It should be noted that the password needs to be encrypted by the bcrypt method to ensure data security.

Finally, after the logical processing is completed, the user is redirected to the login page to ensure that the registration process is completed.

3. Routing settings

In addition to the above implementation process, you also need to add two routes to the routing file, corresponding to the registration page and registration form submission processing. Add the following code to routes/web.php:

Route::get('register', 'Auth\RegisterController@showRegistrationForm')->name('register');
Route::post('register', 'Auth\RegisterController@register');

The above codes correspond to two methods: showRegistrationForm and register. Among them, the get method handles the request for the registration page, and the post method handles the request submitted by the registration form.

At this point, the registration function implementation under Laravel_admin has been completed. Throughout the process, issues that need attention include: the csrf_field form field in the front-end page must exist, the data submitted by the form needs to be verified in the register method and corresponding information prompted, the user password needs to be encrypted in the create method, etc. Only by properly handling these details can the stability and healthy operation of the registration process be ensured.
