Create a movie website using Yii framework

With the popularity of the Internet and people's love for movies, movie websites have become a popular website type. When creating a movie website, a good framework is very necessary. Yii framework is a high-performance PHP framework that is easy to use and has excellent performance. In this article, we will explore how to create a movie website using the Yii framework.

1. Install the Yii framework

Before using the Yii framework, you need to install the framework first. Installing the Yii framework is very simple, just execute the following command in the terminal:

composer create-project yiisoft/yii2-app-basic

This command will create a basic Yii2 application in the current directory. Now you are ready to start creating your movie website.

2. Creating databases and tables

Yii framework provides ActiveRecord, a way to make operating databases easy. In this example, we will create a data table called movies, which contains information such as movie ID, title, director, actors, year, genre, and rating. To create the table, go to the application root directory in the terminal and run the following command:

php yii migrate/create create_movies_table

Then edit the generated migration file to the following content:

<?php

use yiidbMigration;

/**
 * Handles the creation of table `{{%movies}}`.
 */
class m210630_050401_create_movies_table extends Migration
{
    /**
     * {@inheritdoc}
     */
    public function safeUp()
    {
        $this->createTable('{{%movies}}', [
            'id' => $this->primaryKey(),
            'title' => $this->string()->notNull(),
            'director' => $this->string()->notNull(),
            'actors' => $this->text()->notNull(),
            'year' => $this->integer()->notNull(),
            'genre' => $this->string()->notNull(),
            'rating' => $this->decimal(3,1)->notNull(),
        ]);
    }

    /**
     * {@inheritdoc}
     */
    public function safeDown()
    {
        $this->dropTable('{{%movies}}');
    }
}

Now run the migration to create the movies data sheet.

php yii migrate

3. Create movie model

In the Yii framework, it is very easy to define the model of the data table using ActiveRecord. We can create a model named Movie in the models directory and specify the table name and field name in the model definition.

<?php

namespace appmodels;

use yiidbActiveRecord;

class Movie extends ActiveRecord
{
    /**
     * {@inheritdoc}
     */
    public static function tableName()
    {
        return '{{%movies}}';
    }

    /**
     * {@inheritdoc}
     */
    public function rules()
    {
        return [
            [['title', 'director', 'actors', 'year', 'genre', 'rating'], 'required'],
            [['year'], 'integer'],
            [['rating'], 'number'],
            [['actors'], 'string'],
            [['title', 'director', 'genre'], 'string', 'max' => 255],
        ];
    }

    /**
    * {@inheritdoc}
    */
    public function attributeLabels()
    {
        return [
            'id' => 'ID',
            'title' => 'Title',
            'director' => 'Director',
            'actors' => 'Actors',
            'year' => 'Year',
            'genre' => 'Genre',
            'rating' => 'Rating'
        ];
    }
}

4. Create Movie Controller

The movie controller will be responsible for handling all requests regarding movies, such as requests to add, edit, delete, and display movie lists. We can create a controller named MovieController in the controllers directory and add the following code:

<?php

namespace appcontrollers;

use Yii;
use yiiwebController;
use appmodelsMovie;

class MovieController extends Controller
{
    /**
     * Shows all movies.
     *
     * @return string
     */
    public function actionIndex()
    {
        $movies = Movie::find()->all();
        return $this->render('index', ['movies' => $movies]);
    }

    /**
     * Creates a new movie.
     *
     * @return string|yiiwebResponse
     */
    public function actionCreate()
    {
        $model = new Movie();

        if ($model->load(Yii::$app->request->post()) && $model->save()) {
            return $this->redirect(['index']);
        }

        return $this->render('create', [
            'model' => $model,
        ]);
    }

    /**
     * Updates an existing movie.
     *
     * @param integer $id
     * @return string|yiiwebResponse
     * @throws yiiwebNotFoundHttpException
     */
    public function actionUpdate($id)
    {
        $model = $this->findModel($id);

        if ($model->load(Yii::$app->request->post()) && $model->save()) {
            return $this->redirect(['index']);
        }

        return $this->render('update', [
            'model' => $model,
        ]);
    }

    /**
     * Deletes an existing movie.
     *
     * @param integer $id
     * @return yiiwebResponse
     * @throws yiiwebNotFoundHttpException
     */
    public function actionDelete($id)
    {
        $this->findModel($id)->delete();

        return $this->redirect(['index']);
    }

    /**
     * Finds the Movie model based on its primary key value.
     * If the model is not found, a 404 HTTP exception will be thrown.
     *
     * @param integer $id
     * @return ppmodelsMovie
     * @throws NotFoundHttpException if the model cannot be found
     */
    protected function findModel($id)
    {
        if (($model = Movie::findOne($id)) !== null) {
            return $model;
        }

        throw new NotFoundHttpException('The requested page does not exist.');
    }
}

Among them, the actionIndex method will display the list of all movies, and the actionCreate and actionUpdate methods will be used to create and edit movies, The actionDelete method will delete the movie.

5. Create a movie view

Next, we need to create a view file to display the movie list, add movie, and edit movie forms. Store view files in the views/movie directory.

• index.php - used to display the list of movies

<?php

use yiihelpersHtml;
use yiigridGridView;

/* @var $this yiiwebView */
/* @var $movies appmodelsMovie[] */

$this->title = 'Movies';
$this->params['breadcrumbs'][] = $this->title;
?>

<h1><?= Html::encode($this->title) ?></h1>

<p>
    <?= Html::a('Create Movie', ['create'], ['class' => 'btn btn-success']) ?>
</p>

<?= GridView::widget([
    'dataProvider' => new yiidataArrayDataProvider([
        'allModels' => $movies,
        'sort' => [
            'attributes' => [
                'title',
                'director',
                'year',
                'genre',
                'rating',
            ],
        ],
    ]),
    'columns' => [
        ['class' => 'yiigridSerialColumn'],

        'title',
        'director',
        'actors:ntext',
        'year',
        'genre',
        'rating',

        ['class' => 'yiigridActionColumn'],
    ],
]); ?>

• create.php - used to create new movies

<?php

use yiihelpersHtml;
use yiiwidgetsActiveForm;

/* @var $this yiiwebView */
/* @var $model appmodelsMovie */

$this->title = 'Create Movie';
$this->params['breadcrumbs'][] = ['label' => 'Movies', 'url' => ['index']];
$this->params['breadcrumbs'][] = $this->title;
?>
<h1><?= Html::encode($this->title) ?></h1>

<div class="movie-form">

    <?php $form = ActiveForm::begin(); ?>

    <?= $form->field($model, 'title')->textInput(['maxlength' => true]) ?>

    <?= $form->field($model, 'director')->textInput(['maxlength' => true]) ?>

    <?= $form->field($model, 'actors')->textarea(['rows' => 6]) ?>

    <?= $form->field($model, 'year')->textInput() ?>

    <?= $form->field($model, 'genre')->textInput(['maxlength' => true]) ?>

    <?= $form->field($model, 'rating')->textInput() ?>

    <div class="form-group">
        <?= Html::submitButton('Save', ['class' => 'btn btn-success']) ?>
    </div>

    <?php ActiveForm::end(); ?>

</div>

• update.php - for editing movies

<?php

use yiihelpersHtml;
use yiiwidgetsActiveForm;

/* @var $this yiiwebView */
/* @var $model appmodelsMovie */

$this->title = 'Update Movie: ' . $model->title;
$this->params['breadcrumbs'][] = ['label' => 'Movies', 'url' => ['index']];
$this->params['breadcrumbs'][] = ['label' => $model->title, 'url' => ['view', 'id' => $model->id]];
$this->params['breadcrumbs'][] = 'Update';
?>
<h1><?= Html::encode($this->title) ?></h1>

<div class="movie-form">

    <?php $form = ActiveForm::begin(); ?>

    <?= $form->field($model, 'title')->textInput(['maxlength' => true]) ?>

    <?= $form->field($model, 'director')->textInput(['maxlength' => true]) ?>

    <?= $form->field($model, 'actors')->textarea(['rows' => 6]) ?>

    <?= $form->field($model, 'year')->textInput() ?>

    <?= $form->field($model, 'genre')->textInput(['maxlength' => true]) ?>

    <?= $form->field($model, 'rating')->textInput() ?>

    <div class="form-group">
        <?= Html::submitButton('Save', ['class' => 'btn btn-primary']) ?>
    </div>

    <?php ActiveForm::end(); ?>

</div>

6. Run the movie website

Now we have completed the creation of the Yii framework movie website, all The code is all ready. To run the movie website locally, go to the application root directory in the terminal and execute the following command:

php yii serve

This will start a local web server and run your application on port 8000. Now, you can open http://localhost:8000/ in your browser and see your movie website.

In this article, we have demonstrated how to create a movie website using Yii framework. Using the Yii framework will speed up your development and provide many useful features, such as ActiveRecord, MVC architecture, form validation, security, and more.
