Detailed explanation of the method of staying on the current page after adding, deleting, modifying and checking in Yii2-PHP Tutorial-php.cn

ImplementationAdd, Delete, Modify and CheckIt will remain on the current page after the operation is successful, which can give the user a good experience. However, the Yii2 framework itself does not have the effect of remaining on the current page after theadd, delete, modify,operation is successful. To achieve such an effect, you have to write it yourself. My principle is not to leave the core code alone and always stick to my own principles. Now that I have achieved it, I will share it. Different paths lead to the same goal. If there is a better way to implementAdd, Delete, Modify and Check, please feel free to communicate.

Encapsulation code

There are two files ActionColumn.php and Helper.php

1 , ActionColumn.php file

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 .= '

'; return $data; } }

Copy after login

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; } }

1. Call it directly and replace the ['class' => 'yiigridActionColumn'] that comes with Yii2 with the new one we wrote ['class' => 'common\components\ActionColumn'].

2. If the direct call cannot meet your requirements, you can customize the link. The custom link is written as follows:

[ '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 ], ], ],

1. Use get to get returnUrl, code: $returnUrl = Yii::$ app->request->get('returnUrl'); .

1. The advantage of this method is that it does not leave the core code, and the calling method retains the Yii2 built-in method.

2. The disadvantage is that when customizing the link, you need to write out each operation update, view, and delete. You cannot use this kind of 'template' => '{view}{ update}{delete}' is simple and comfortable to look at. You can write it according to your needs.

Okay, that’s the entire content of this article. I hope the content of this article can be of some help to everyone’s study or work. If you have any questions, you can leave a message to communicate.
