yii2.0增删改查实例讲解
一.创建数据库文件.
创建表 CREATE TABLE `resource` ( `id` int(10) NOT NULL AUTO_INCREMENT, `texture` varchar(50) NOT NULL COMMENT \'材质\', `mark` varchar(50) NOT NULL COMMENT \'牌号\', `manufacturers` varchar(100) NOT NULL COMMENT \'厂家\', `price` int(11) NOT NULL COMMENT \'价格\', PRIMARY KEY (`id`) ) ENGINE=MyISAM AUTO_INCREMENT=10 DEFAULT CHARSET=utf8;
INSERT INTO `resource` VALUES (\'1\', \'PP\', \'300H\', \'中沙石化\', \'8300\'); INSERT INTO `resource` VALUES (\'2\', \'LDPE\', \'LD605\', \'燕山石化\', \'9850\'); INSERT INTO `resource` VALUES (\'3\', \'ABS\', \'D-190 \', \'镇江奇美\', \'11300\'); INSERT INTO `resource` VALUES (\'4\', \'ABS\', \'D-180 \', \'镇江奇美\', \'11500\'); INSERT INTO `resource` VALUES (\'5\', \'ABS\', \'D-2400 \', \'镇江奇美\', \'17600\'); INSERT INTO `resource` VALUES (\'6\', \'YH\', \'YH100\', \'测试\', \'199466\'); INSERT INTO `resource` VALUES (\'7\', \'YH\', \'YH200\', \'测试\', \'56256\'); INSERT INTO `resource` VALUES (\'8\', \'QW\', \'QW-21\', \'压紧\', \'19865\'); INSERT INTO `resource` VALUES (\'9\', \'ZX\', \'ZX-82\', \'水果\', \'98632\'); INSERT INTO `resource` VALUES (\'10\', \'OP\', \'OP98\', \'叶城\', \'38941\');
二.定义控制器controller
namespace app\\controllers;
use Yii;
use yii\\web\\Controller;
use yii\\data\\Pagination;
use app\\models\\Resources;
class ResourcesController extends Controller
{
/**
* 数据列表
*/
public function actionIndex($id = \'\')
{
$query = Resources::find();
$pages = new Pagination([
\'defaultPageSize\' => \'4\',
\'totalCount\' => $query->count(),
]);
$model = $query->orderBy(\'id DESC\')
->offset($pages->offset)
->limit($pages->limit)
->all();
return $this->render(\'index\', [
\'model\' => $model,
\'pages\' => $pages,
\'id\' => $id,
]);
}
/**
* 添加数据
*/
public function actionAdd($id = \'\')
{
if($id){
$model = Resources::findOne($id);
}else{
$model = new Resources();
}
if($model->load(Yii::$app->request->post()) && $model->validate()){
$model->save();
return $this->redirect(array(\'resources/index\'));
}
return $this->render(\'add\', [
\'model\' => $model,
\'id\' => $id,
]);
}
/**
* 更新数据
*/
public function actionUpdate($id)
{
return $this->redirect(array(\'resources/add\',\'id\' => $id));
}
/**
* 删除数据
*/
public function actionDelete($id)
{
Resources::findOne($id)->delete();
return $this->redirect(array(\'resources/index\'));
}
}
三.定义model
namespace app\\models;
use Yii;
/**
* This is the model class for table "resource".
*
* @property integer $id
* @property string $texture
* @property string $mark
* @property string $manufacturers
* @property integer $price
*/
class Resources extends \\yii\\db\\ActiveRecord
{
/**
* @inheritdoc
*/
public static function tableName()
{
return \'resource\';
}
/**
* @inheritdoc
*/
public function rules()
{
return [
[[\'texture\', \'mark\', \'manufacturers\', \'price\'], \'required\'],
[[\'price\'], \'integer\'],
[[\'texture\', \'mark\'], \'string\', \'max\' => 50],
[[\'manufacturers\'], \'string\', \'max\' => 100],
];
}
/**
* @inheritdoc
*/
public function attributeLabels()
{
return [
\'id\' => "ID",
\'texture\' =>"材质",
\'mark\' => Yii::t(\'app\', \'牌号\'),
\'manufacturers\' => Yii::t(\'app\', \'厂家\'),
\'price\' => Yii::t(\'app\', \'价格\'),
];
}
}
四.定义视图view
1.index.php
<?php use yii\\helpers\\html; use yii\\widgets\\LinkPager; ?> <!DOCTYPE html> <html> <head> <meta charset="utf-8" /> <title>资源列表</title> <style type="text/css"> .list-head{margin-bottom:10px;overflow:hidden;} .list-head strong{padding:6px 0;font-size:16px;} .list-table{width:100%;} .list-table thead{font-weight:bold;} .list-table td{line-height:30px;text-align:center;border:1px solid #eee;} .fl{float:left;} .fr{float:right;} </style> </head> <body> <?= $id ?> <div class="list-head"> <strong class="fl">资源列表</strong> <a href="index.php?r=resources/add" class="btn btn-primary fr">添加</a> </div> <table class="list-table"> <thead> <tr> <td>ID</td> <td>材质</td> <td>牌号</td> <td>厂家</td> <td>价格</td> <td>操作</td> </tr> </thead> <tbody> <?php foreach($model as $resource): ?> <tr> <td><?= Html::encode($resource->id) ?></td> <td><?= Html::encode($resource->texture) ?></td> <td><?= Html::encode($resource->mark) ?></td> <td><?= Html::encode($resource->manufacturers) ?></td> <td><?= Html::encode($resource->price) ?></td> <td> <a href="index.php?r=resources/update&id=<?= Html::encode($resource->id) ?>">编辑</a> <a href="index.php?r=resources/delete&id=<?= Html::encode($resource->id) ?>" onclick="if(confirm(\'确定删除该条数据?\')==false)return false;">删除</a> </td> </tr> <?php endforeach; ?> </tbody> </table> <?= LinkPager::widget([\'pagination\' => $pages]) ?> </body> </html>
2.add.php
<?php
use yii\\helpers\\Html;
use yii\\widgets\\ActiveForm;
?>
<?php $form = ActiveForm::begin(); ?>
<?php if($id): ?>
<?= $form->field($model, \'id\')->textInput([\'value\' => $id, \'disabled\' => \'disabled\']) ?>
<?php endif; ?>
<?= $form->field($model, \'texture\') ?>
<?= $form->field($model, \'mark\') ?>
<?= $form->field($model, \'manufacturers\') ?>
<?= $form->field($model, \'price\') ?>
<div class="form-group">
<?php if($id): ?>
<?= Html::submitButton(\'修改\', [\'class\' => \'btn btn-primary\']) ?>
<?php else:?>
<?= Html::submitButton(\'添加\', [\'class\' => \'btn btn-primary\']) ?>
<?php endif; ?>
</div>
<?php ActiveForm::end(); ?>
五.运行结果如下:
