Objective

This article is mainly about Yii 2.0 in the form of the use of small parts of the relevant content, shared out for everyone to refer to the study, the following to see the detailed introduction:

How to use

First create the model layer, because to use the form widget, so to load the corresponding components, the components required here are Yii\widgets\activeform yii\helpers\html

Next we write the method in the model definition class, first we define the name value that needs to use the form widget

Not much to say on the code

<?phpnamespace frontend\models;use yii\base\model;use yii\widgets\activeform;use yii\helpers\Html;class Form Extends model{public    $name;    public $pwd;    public $sex;    public $hobby;    public $age;    Public Function Rules () {        return[                ];    }    Public Function Attributelabels () {        return[        ' name ' = ' username ',        ' pwd ' = ' password ',        ' sex ' = ' gender ',        ' hobby ' = ' hobby ',        ' age ' = ' ages '        ;    }    static public Function Dataarr ($data) {        $arr = array ();        foreach ($data as $key = + $value) {        $arr [$value [' kid ']] = $value [' Kname '];        }        return $arr;    }}

In this model there is a way to convert English headers into Chinese attributulabels

And we're dealing with a single-choice multi-Select and a drop-down box worth the way Dataarr

Next we need to create a controller

<?phpnamespace frontend\controllers;use yii\web\controller;use yii;use db;use frontend\models\Form;class Logincontroller extends Controller{public function Actionindex () {$sql = ' select Kid,kname from Exam_tiku '; $data = Yii:: $a Pp->db->createcommand ($sql)->queryall () $arr = Form::d ataarr ($data);//var_dump ($arr);d ie; $model = new Form return $this->render (' Index ', [' model ' = ' $model, ' data ' = $arr]); Public Function Actionadd () {$data = Yii:: $app->request->post (); echo $name = $data [' Form '] [' name '];}}

And then it's on the view level of my door.

<?php/*** Created by phpstorm.* user:jinlei* date:2017/5/10* time:9:41*/use yii\helpers\html;use yii\widgets\Active Form; $form = Activeform::begin ([' id ' = ' login-form ', ' options ' = ' = ' class ' = ' form-horizontal '], ' action ' = > '? R=login/add ', ' method ' = ' post ', '])? ><?= $form->field ($model, ' name ')? ><?= $form->field ($ Model, ' pwd ')->passwordinput ()? ><?= $form->field ($model, ' sex ')->radiolist ([' 0 ' = ' male ', ' 1 ' + ') Female '])? ><?= $form->field ($model, ' hobby ')->checkboxlist ([' basketball ' = ' basketball ', ' baseball ' = ' baseball ', ' Swim ' = ' swim ']? ><?= $form->field ($model, ' age ')->dropdownlist ($data)? ><p class= "Form-group" ><p class= "col-lg-offset-1 col-lg-11″><?= Html::submitbutton (' Login ', [' class ' = ' btn btn-primary '])? ></p></p><?php activeform::end ()?>

In this page we show the text box password box single-select multi-select dropdown box where the data for the drop-down box is read from the DB
