Yii2实现增删改查后留在当前页的方法详解

　　前言

　　实现增删改查操作成功后仍留在当前页，能给用户一个良好的体验。但是 Yii2 框架本身是没有在增删改查操作成功后仍留在当前页的效果的，要实现这样的一个效果得自己写。我的原则是不动核心代码，始终坚持自己的原则，现实现了我把它分享出来。殊途同归，如有更好的实现方法，欢迎交流。

　　需求分析

　　一、实现增删改查后操作成功后仍然留在当前页面。

　　1、链接的效果图

　　封装代码

　　共有两个文件ActionColumn.php和Helper.php1、ActionColumn.php文件

　　 <?php use Closure; use kartik\icons\Icon; use Yii; use yii\grid\Column; use yii\helpers\ArrayHelper; use yii\helpers\Html; use yii\helpers\Url; use common\components\Helper; /* *重写ActionColumn */ class ActionColumn extends Column { public $buttons; private $defaultButtons = []; private $callbackButtons; public $controller; public $urlCreator; public $url_append = ; public $appendReturnUrl = true; //默认为true,返回当前链接 public function init() { parent::init(); $this->defaultButtons = [ [ url => view, icon => eye, class => btn btn-success btn-xs, label => Yii::t(yii, View), appendReturnUrl => false, url_append => , keyParam => id,//是否传id,不传设置null ], [ url => update, icon => pencil, class => btn btn-primary btn-xs, label => Yii::t(yii, Update), ], [ url => delete, icon => trash-o, class => btn btn-danger btn-xs, label => Yii::t(yii, Delete), options => [ data-action => delete, ], ] ]; if (null === $this->buttons) { $this->buttons = $this->defaultButtons; } elseif ($this->buttons instanceof Closure) { $this->callbackButtons = $this->buttons; } } public function createUrl( $action, $model, $key, $index, $appendReturnUrl = null, $url_append = null, $keyParam = id, $attrs = [] ) { if ($this->urlCreator instanceof Closure) { return call_user_func($this->urlCreator, $action, $model, $key, $index); } else { $params = []; if (is_array($key)) { $params = $key; } else { if (is_null($keyParam) === false) { $params = [$keyParam => (string)$key]; } } $params[0] = $this->controller ? $this->controller . / . $action : $action; foreach ($attrs as $attrName) { if ($attrName === model) { $params[model] = $model; } elseif ($attrName === mainCategory.category_group_id && $model->getMainCategory()) { $params[category_group_id] = $model->getMainCategory()->category_group_id; } else { $params[$attrName] = $model->getAttribute($attrName); } } if (is_null($appendReturnUrl) === true) { $appendReturnUrl = $this->appendReturnUrl; } if (is_null($url_append) === true) { $url_append = $this->url_append; } if ($appendReturnUrl) { $params[returnUrl] = Helper::getReturnUrl(); } return Url::toRoute($params) . $url_append; } } protected function renderDataCellContent($model, $key, $index) { if ($this->callbackButtons instanceof Closure) { $btns = call_user_func($this->callbackButtons, $model, $key, $index, $this); if (null === $btns) { $this->buttons = $this->defaultButtons; } else { $this->buttons = $btns; } } $min_width = count($this->buttons) * 34; //34 is button-width $data = Html::beginTag(div, [class => btn-group, style => min-width: . $min_width . px]); foreach ($this->buttons as $button) { $appendReturnUrl = ArrayHelper::getValue($button, appendReturnUrl, $this->appendReturnUrl); $url_append = ArrayHelper::getValue($button, url_append, $this->url_append); $keyParam = ArrayHelper::getValue($button, keyParam, id); $attrs = ArrayHelper::getValue($button, attrs, []); Html::addCssClass($button, btn); Html::addCssClass($button, btn-sm); $buttonText = isset($button[text]) ? . $button[text] : ; $data .= Html::a( $button[label] . $buttonText, $url = $this->createUrl( $button[url], $model, $key, $index, $appendReturnUrl, $url_append, $keyParam, $attrs ), ArrayHelper::merge( isset($button[options]) ? $button[options] : [], [ //data-pjax => 0, // data-action => $button[url], class => $button[class], title => $button[label], ] ) ) . ; } $data .= </div>; return $data; } }

　　2、Helper.php文件

　　 <?php use Yii; class Helper { private static $returnUrl; public static $returnUrlWithoutHistory = false; /** * @param int $depth * @return string */ public static function getReturnUrl() { if (is_null(self::$returnUrl)) { $url = parse_url(Yii::$app->request->url); $returnUrlParams = []; if (isset($url[query])) { $parts = explode(&, $url[query]); foreach ($parts as $part) { $pieces = explode(=, $part); if (static::$returnUrlWithoutHistory && count($pieces) == 2 && $pieces[0] === returnUrl) { continue; } if (count($pieces) == 2 && strlen($pieces[1]) > 0) { $returnUrlParams[] = $part; } } } if (count($returnUrlParams) > 0) { self::$returnUrl = $url[path] . ? . implode(&, $returnUrlParams); } else { self::$returnUrl = $url[path]; } } return self::$returnUrl; } }

　　视图调用

　　1、直接调用，把Yii2自带的[class => yiigridActionColumn]换成我们新写的[class => common\components\ActionColumn] 。

　　2、如直接调用不能满足你的要求可以自定义链接，自定义链接的写法如下：

　　 [ class => common\components\ActionColumn, urlCreator => function($action, $model, $key, $index) use ($id) { //自定义链接传的参数 $params = [ $action, option_id => $model->option_id, id => $id, ]; $params[returnUrl] = common\components\Helper::getReturnUrl(); return yii\helpers\Url::toRoute($params); }, buttons => [ [ url =>view, class => btn btn-success btn-xs, label => Yii::t(yii, View), appendReturnUrl => false,//是否保留当前URL，默认为true url_append => , keyParam => id, //是否传id,不传设置null ], [ url => update, class => btn btn-primary btn-xs btn-sm, label => Yii::t(yii, Update), appendReturnUrl => true,//是否保留当前URL，默认为true url_append => , keyParam => id, //是否传id,不传设置null ], [ url => delete, class => btn btn-danger btn-xs btn-sm, label => Yii::t(yii, Delete), options => [ data-action => delete, ], appendReturnUrl => true,//是否保留当前URL，默认为true url_append => , keyParam => id, //是否传id,不传设置null ], ], ],

　　3、新增的话，这么引用<?= Html::a(Yii::t(yii, Create), [create,returnUrl => Helper::getReturnUrl()], [class => btn btn-success]) ?> 。

　　控制器逻辑

　　1、用get获取returnUrl，代码：$returnUrl = Yii::$app->request->get(returnUrl); 。

　　2、跳转到的URL：return $this->redirect($returnUrl); 。

　　分析总结

　　1、此方法的好处是不动核心代码，调用方式保留了Yii2自带的方式。

　　2、不足之处是在自定义链接的时候需要把每一个操作update、view、delete都写出来，不能用这种template => {view}{update}{delete}简单且看着舒服能根据需求去写了。
