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。
