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 . 'https://www.jb51.net/' . $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：
