yii2.0 learning journey (b)

Introduction: The last time we simply know a bit yii2.0 installation, basic model (add, delete, change, search) operations

First, the front and back data exchange

* If you think the default top style ugly, it can be turned off *

* Bottom may be so turned off *

(1) mvc cooperative operation data

A controller (c), a display method and a receiving method

    /**
     * 列表
     * @return string
     */
    public function actionIndex(){
        $where = array();
        $is_page = false;
        FcArticle::getConditionByList('a_id,article_title,author',$where,'a_id desc',$is_page,10);
        return $this->render('index', [
            'list' => FcArticle::$countries,
            'pagination' => FcArticle::$pagination,
            'is_page'=>$is_page
        ]); 
    } 

    / * * 
     * Add 
     * @return String 
     * / 
    public  function actionAdd () 
    { 

        $ Model = new new FcArticle ();

        IF ( $ Model -> Load (\ Yii :: $ App -> request-> POST ()) && $ model -> the validate ())

            $ model -> INSERT ();

                 'Model' => $ Model , 
            ]); 
        } 
    } 

    / * * 
     * Edit 
     * @return String 
     * / 
    public  function actionUpdate () 
    {

        } the else  IF (\ Yii :: $ App-> request-> isPost) {
             $ postParams = \ Yii :: $ App -> request-> bodyParams; // POST request method, a multidimensional array 
            $ A_ID = $ postParams [ 'FcArticle'] [ 'A_ID' ]; 
        } 

        $ Model = FcArticle the findOne :: ( Array ( 'A_ID' => $ A_ID ));
         IF ( $ Model -> Load (\ Yii :: $ App -> request-> POST ()) && $ Model -> the validate () ) 
        { 
            // edited rules model which, by then, the operation data storage 
            // https://www.jianshu.com/p/4d5a3a8256d3 include the URL, here is how to remove the index.php approach 
            $ Model ->update();
            return $this->redirect('index.php?r=test/index');
        }
        else
        {
            return $this->render('update', [
                'model' => $model,
                'a_id'=>$a_id
            ]);
        }
    }

Models (m), himself a bit in the original package basis

To reference a page framework document

use Yii \ Data \ Pagination;     // paging class

            Self:: $ the pagination = new new Pagination ([
                 'defaultPageSize' => $ pageSize , // page shows the number of

    public function getOneConditionInfo($field = '',$condition = array()){
        $query = self::find();

yii2.0 Notes

1, the controller method name must be a small hump way;

For example: actionFormadd, error: actionFormAdd (This visit is less than)

2, was going to be a native form tag, however, found not compatible with validation rules, so do strike
