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
<?phpuse Closure;use kartikiconsIcon;use Yii;use yiigridColumn;use yiihelpersArrayHelper;use yiihelpersHtml;use yiihelpersUrl;use commoncomponentsHelper;/**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
<?phpuse 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" => "commoncomponentsActionColumn"] 。
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" => "commoncomponentsActionColumn", "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, ]; $params["returnUrl"] = commoncomponentsHelper::getReturnUrl(); return yiihelpersUrl::toRoute($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。
