functions random from database in php? - php

Question

I have a function:
function nomor_registrasi() {
$sql=mysql_query("select * from pendaftaran order by no_registrasi DESC LIMIT 0,1");
$data=mysql_fetch_array($sql);
$kodeawal=substr($data['no_registrasi'],6,7)+1;
if($kodeawal<10) {
$kode='SMKGJ00'.$kodeawal;
} else if ($kodeawal > 9 && $kodeawal <=99) {
$kode='SMKGJ0'.$kodeawal;
} else {
$kode='SMKGJ'.$kodeawal;
}
return $kode;
}
If a user registers from a form, the user will have no_registrasi, for example: last no_registrasi record in the table is SMKGJ006, so the user will have SMKGJ007, etc..
I'm starting learning the php framework: laravel.
How can I code this function using laravel?

Answer 1

I use laravel 4!
If you want to put your function to run when user register you need to put it in Controller that respond for registration of users.
The Controllers are in folder /app/controllers .
If you recent(1 minute ago) installed **laravel 4.1 and not have the Controller that respond for registration of users (like me, after installation I have a page on with is only image and you arrived and no link to register and login like after installation of yii), when you need to create it.
To create controller UsersController put in /app/controllers file with name UsersController.php and code:
<?php
class UsersController extends BaseController {
//!!show the form for registration from root /app/views/some_file name_like_register.blade.php in witch is html form
public function getRegister() {
return View::make('users/register');
}
//!! register user when post data come from form
public function postRegister() {
//Here you can put your function
$rules = User::$validation;
$validation = Validator::make(Input::all(), $rules);
if ($validation->fails()) {
return Redirect::to('public/users/register')->withErrors($validation)->withInput();
}
$user = new User();
$user->fill(Input::all());
$id = $user->register();
return $this->getMessage("Registered successfull.");
}
}
Add changes to User model. After
class User extends Eloquent implements UserInterface, RemindableInterface {
add
//form validation
public static $validation = array(
'email' => 'required|email|unique:users',
'username' => 'required|alpha_num|unique:users',
'password' => 'required|confirmed|min:6',
);
//for registration
protected $fillable = array('username', 'email', 'password');
//
public function register() {
//Here you can put your function
$this->password = Hash::make($this->password);
$this->activationCode = $this->generateCode();
$this->save();
Log::info("User [{$this->email}] registered. Activation code: {$this->activationCode}");
/*$this->sendActivationMail();*/ //send email with activation code, set 1 to isActive value
return $this->id;
}
protected function sendActivationMail() { /*do*/}
protected function generateCode() {
return Str::random();
}
Make file with name register.blade.php in /app/views/ with code:
#section('title')
#section('content')
<div class="container">
#if ($errors->all())
<div class="alert alert-danger">
#foreach ($errors->all() as $error)
<p>{{ $error }}</p>
#endforeach
</div>
#endif
<h1>Registration</h1>
{{ Form::open(array('url' => '/users/register', 'role' => 'form', 'class' => 'form-horizontal')) }}
<div class="form-group">
{{ Form::label('email', 'E-Mail', array('class' => 'col-sm-2 control-label')) }}
<div class="col-sm-5">
{{ Form::email('email', null, array('class' => 'form-control')) }}
</div>
</div>
<div class="form-group">
{{ Form::label('username', 'login', array('class' => 'col-sm-2 control-label')) }}
<div class="col-sm-5">
{{ Form::text('username', null, array('class' => 'form-control')) }}
</div>
</div>
<div class="form-group">
{{ Form::label('password', 'password', array('class' => 'col-sm-2 control-label')) }}
<div class="col-sm-5">
{{ Form::password('password', array('class' => 'form-control')) }}
</div>
</div>
<div class="form-group">
{{ Form::label('password_confirmation', 'retype pass', array('class' => 'col-sm-2 control-label')) }}
<div class="col-sm-5">
{{ Form::password('password_confirmation', array('class' => 'form-control')) }}
</div>
</div>
<div class="form-group">
<div class="col-sm-2"> </div>
<div class="col-sm-5">
<button type="submit" class="btn btn-primary">Go</button>
</div>
</div>
{{ Form::close() }}
In table user add your registraci cell. Table structure is
Schema::create('users', function(Blueprint $table) {
$table->increments('id');
$table->string('email')->unique();
$table->string('password', 60);
$table->string('username')->unique();
$table->boolean('isAdmin');
$table->boolean('isActive')->index();
$table->string('activationCode');
$table->rememberToken();
$table->timestamps();
// also add your registraci
$table->string('registraci', 200);
});
To turn on database driver open /app/config/database.php and change if need
//select mysql or other
'default' => 'mysql'
...
//database and other change here
'mysql' => array(
'driver' => 'mysql',
'host' => 'localhost',
'database' => 'laravel',
'username' => 'root',
'password' => '',
'charset' => 'utf8',
'collation' => 'utf8_unicode_ci',
'prefix' => '',
)
If I lost something you will get errors messages not like oops but real problems
To see errors go to /app/config/app.php and set to
'debug' => true,

Add a column with name no_registrasi in laravel table with users and use your old code when register new user, only change table name and other columns name.
https://laravel.com/docs/5.0/schema
Schema::table('users', function($table)
{
$table->string('no_registrasi');
});
