Yii2实现增删改查后留在当前页的方法详解

前端之家收集整理的这篇文章主要介绍了Yii2实现增删改查后留在当前页的方法详解前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。

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、链接效果

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','Update'),],[
'url' => 'delete','icon' => 'trash-o','class' => 'btn btn-danger btn-xs','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,$action,$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($model,$index)
{
if ($this->callbackButtons instanceof Closure) {
$btns = call_user_func($this->callbackButtons,$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(
$button['url'],$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;
}

}

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['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:

'common\components\ActionColumn','urlCreator' => function($action,$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',//是否保留当前URL,默认为true 'url_append' => '',不传设置null ],[ 'url' => 'update','class' => 'btn btn-primary btn-xs btn-sm','appendReturnUrl' => true,[ 'url' => 'delete','class' => 'btn btn-danger btn-xs btn-sm',

3、新增的话,这么引用 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。
