kartik 树视图显示每个节点单击的不同视图
kartik tree view show different views on each node click
我正在研究 Yii2。我使用 kartik tree manager 创建了一棵树。默认情况下，在每个节点上单击它会显示 ID、name 等。但我想显示其他数据。下面是我的代码
<?=
TreeView::widget([
'query' => \common\models\MdcNode::find()->addOrderBy('root, lft'),
'headingOptions' => ['label' => 'Root'],
'rootOptions' => ['label'=>'<span class="text-primary">Root</span>'],
'topRootAsHeading' => true, // this will override the headingOptions
'fontAwesome' => true,
'isAdmin' => false,
//'nodeView' => '',
'toolbar' => [
TreeView::BTN_REFRESH => false,
TreeView::BTN_CREATE => false,
TreeView::BTN_CREATE_ROOT => false,
TreeView::BTN_REMOVE => false,
TreeView::BTN_SEPARATOR => false,

经过一些RnD我发现细节window在<div id="w0-detail" class="kv-detail-container">
下
在我的 JS 中，我试图隐藏它 $('#w0-detail').hide();。现在我想根据点击的不同节点显示视图。

现在我收到一个错误 Setting unknown property: kartik\tree\TreeView::treeViewSettings。我不知道为什么会显示此错误。我一定是遗漏了一些我不知道的东西，我坚持了下来
非常感谢任何帮助。
以下结果是在 不需要 js 隐藏细节的情况下得到的。通过隐藏细节，将不会显示 nodeAddlViews。这些节点包含在 {detail} 中。如果您要取消隐藏细节，您将在 5 个 nodeAddlViews 之一中显示额外数据。

我发现上面的 Treeview 设置，仍然打开了 {Detail} 的面包屑部分，保存和重置按钮仍然启用。
下面模型中的 isDisabled 部分特别重要，因为它不允许访问与 vendor\kartik-v\yii2-tree-manager\src\views_form.php.（第 184 行）的内置面包屑部分关联的保存和重置按钮这里：
if ($node->isDisabled()) {
$inputOpts['disabled'] = true;
}

use Yii;
class KrajeeProductTree extends \kartik\tree\models\Tree

{
return \frontend\components\Utilities::userdb();
}
public static function tableName()
{
return 'works_krajee_product_tree';
}
public function isDisabled()
{
//so if the user is an admin he will be able to edit the tree otherwise the tree will be disabled
//but the nodes will be clickable and section 5 will be available.
if (Yii::$app->user->can('Manage Admin')) {
return false;
} else { return true; }
}
public function rules()
{
return [
[['product_id','productcategory_id','productsubcategory_id'],'integer'],
[['product_id','productcategory_id','productsubcategory_id'],'default','value'=>null],
[['product_id','productcategory_id','productsubcategory_id'],'safe']
];
}
}
上面的模型反映了添加了 3 个外键，每个主键在它们各自的 table 中已经被添加到 Krajeeproducttree table.
下面的控制器从这 3 个 table 构建了一棵树。每次用户单击刷新面包屑时，都会重建树。
frontend\controllers\KrajeeproducttreeController.php
<?php
namespace frontend\controllers;
use frontend\models\KrajeeProductTree;
use frontend\models\Productcategory;
use frontend\models\Productsubcategory;
use frontend\models\Product;

{
return [
'verbs' => [
'class' => VerbFilter::className(),

'rules' => [

'allow' => true,
'roles' => ['@'],
],
[
'allow' => false,
'roles' => ['?'],
],
[
'allow' => true,
'verbs' => ['POST']
],
],
],
];
}
public function actionIndex()
{
return $this->render('index');
}
public function actionPopulate()
{
//remove all data in the database
KrajeeProductTree::deleteAll();
//rebuild the database given data from productcategory ie. postcode, productsubcategory ie. street, product ie. house
//create the root and call it Run
$root = new KrajeeProductTree(['name'=>'Run']);
$root->makeRoot();
//create the postcode nodes
$allpostcodes =[];
$allpostcodes = Productcategory::find()->orderBy('id')->all();
foreach ($allpostcodes as $key => $value)
{
$newpostcodenode = new KrajeeProductTree(['name'=>$allpostcodes[$key]['name']]);
$newpostcodenode->productcategory_id = $allpostcodes[$key]['id'];
$newpostcodenode->prependTo($root);
$allstreets = [];
$allstreets = Productsubcategory::find()
->where(['productcategory_id'=>$allpostcodes[$key]['id']])
->all();
//create the street nodes associated with this new node
$allhouses = [];
foreach ($allstreets as $key => $value)
{
$newstreetnode = new KrajeeProductTree(['name'=>$allstreets[$key]['name']]);
$newstreetnode->productsubcategory_id = $allstreets[$key]['id'] ;
$newstreetnode->prependTo($newpostcodenode);
$allhouses = Product::find()
->where(['productsubcategory_id'=>$allstreets[$key]['id']])
->andWhere(['productcategory_id'=>$allstreets[$key]['productcategory_id']])
->andWhere(['isactive'=>1])
->all();
//create the house nodes associated with this new steet node
foreach ($allhouses as $key => $value)
{
$newhousenode = new KrajeeProductTree(['name'=>$allhouses[$key]['productnumber']]);
$newhousenode->product_id = $allhouses[$key]['id'];
$newhousenode->prependTo($newstreetnode);
}
}
}
return $this->render('index');
}
}
frontend\config\main.php 在模块部分下。
'treemanager' => [
'class' => 'kartik\tree\Module',
'treeViewSettings'=> [
'nodeView' => '@kvtree/views/_form',
'nodeAddlViews' => [
1 => '',
2 => '',
3 => '',
4 => '',
5 => '@app/views/krajeeproducttree/product',
]]
],
正如 Kartik-v 所提到的，如果视图在 frontend\config\main.php.
中的 treeViewSettings 下列出，则 $node 变量由视图继承
frontend\views\krajeeproducttree\product.php
<?php
use Yii;
use yii\helpers\Url;
use yii\helpers\Html;
?>
<div class="krajeeproducttree-product">
<br>
<?php
if ($node->product_id > 0){
echo Html::a('<h4>View House Details: ' .$node->name. '</h4>',Url::toRoute(['/product/view','id'=>$node->product_id]));
}
if ($node->productsubcategory_id > 0){
echo Html::a('<h4>View Street Details: ' .$node->name. '</h4>',Url::toRoute(['/productsubcategory/view','id'=>$node->productsubcategory_id]));
}
if ($node->productcategory_id > 0){
echo Html::a('<h4>View Postcode Details: ' .$node->name. '</h4>',Url::toRoute(['/productcategory/view','id'=>$node->productcategory_id]));
}
?>
<br>
</div>
希望这对您或将来的某个人有所帮助。
对费萨尔的回应：
令人困惑...是的，product.php 只有在扩展模型中有指向它们的 table 的外部 ID 键时才有用，这样您就可以 link 带有 [=148= 的节点] 到与 table 关联的 controller/action/id。我这样做是为了避免点击每个节点时显示大量信息。
这是没有外键的控制器：
public function actionPopulate()
{
//remove all data in the database
KrajeeProductTree::deleteAll();
//rebuild the database given data from productcategory ie. postcode, productsubcategory ie. street, product ie. house
//create the root and call it Run
$root = new KrajeeProductTree(['name'=>'Run']);
$root->makeRoot();
//create the postcode nodes
$allpostcodes =[];
$allpostcodes = Productcategory::find()->orderBy('id')->all();
foreach ($allpostcodes as $key => $value)
{
$newpostcodenode = new KrajeeProductTree(['name'=>$allpostcodes[$key]['name']]);
$newpostcodenode->prependTo($root);
$allstreets = [];
$allstreets = Productsubcategory::find()
->where(['productcategory_id'=>$allpostcodes[$key]['id']])
->all();
//create the street nodes associated with this new node
$allhouses = [];
foreach ($allstreets as $key => $value)
{
$newstreetnode = new KrajeeProductTree(['name'=>$allstreets[$key]['name']]);
$newstreetnode->prependTo($newpostcodenode);
$allhouses = Product::find()
->where(['productsubcategory_id'=>$allstreets[$key]['id']])
->andWhere(['productcategory_id'=>$allstreets[$key]['productcategory_id']])
->andWhere(['isactive'=>1])
->all();
//create the house nodes associated with this new steet node
foreach ($allhouses as $key => $value)
{
$newhousenode = new KrajeeProductTree(['name'=>$allhouses[$key]['productnumber']]);
$newhousenode->prependTo($newstreetnode);
}
}
}
return $this->render('index');
}
您会注意到子节点被添加到 ie 之前。 prependTo 父节点。您可以为您打算为其创建树的模块中的所有模型执行此操作。您还会注意到控制器是从 NodeController 扩展而来的。
Here is the format of the tables themselves.
产品类别即。邮政编码有一个 id 自动增量字段。产品子类别即。 streets 也有一个 id autoincrement 字段。此外，Productsubcategory 有一个指向 Productcategory table.
的外键 productcategory_id
产品table 即。 houses 有它的 id autoincrement 字段。此外，它还有两个外键，即。 productsubcategory_id 指向产品子类别 table。它还有一个指向产品类别 table.
的外键 productcategory_id
这个结构有助于link三个层次，也可以在上面link.
中使用上面模型中使用的Yii2的关系建模结构
每条街道 link 对应一个邮政编码，即。 productcategory_id 来自 table
Productsubcategory (street) 与 Productcategory table 的 id 字段相同，
此结构还有助于检索每个节点的数据。所以下面的代码在controller links 两级：
$allstreets = Productsubcategory::find()
->where(['productcategory_id'=>$allpostcodes[$key]['id']])
->all();
你在frontend\config\main.php下添加了nodeView，这个有必要吗？我也找不到 ...krajeeproducttree/product 在你的代码中。
nodeView 是一个别名，与指向呈现细节的视图的路径相连，可在 vendor\kartik-v\yii2-tree-manager\src\Module 的第 81 行找到。如果config\main.php下没有提到，默认值为'@kvtree/views/_form'。 This _form is extended by the nodeAddlViews and has to exist if you want to show additional information. _form 可以修改并插入模型的视图下，但必须正确别名，例如@app \ views \krajeeproducttree \ _form.php.
现在我收到错误设置未知 属性: kartik\tree\TreeView::treeViewSettings...
treeViewSettings 不是 \vendor\kartik-v\yii2-tree-manager\src\TreeView 下列出的变量，但是在第 137 行存在 nodeView，在第 153 行存在 nodeAddlViews，因此您可以单独使用这些变量。
IE。不在您选择构建的每个单独树的 treeViewSettings 中。
我在你的代码中也找不到.....krajeeproducttree/product...
是的，控制器 KrajeeproductreeController 应该有一个名为 product 的操作来调用产品视图 product.php。这通常是预期的，但如果您在为 nodeAddlViews 创建的任何视图中执行 var_dump($node)，您将获得 $node 的数组。通常你必须在控制器中传递一个带有渲染的参数，例如。
return $this->render('index', [
'node' => $node
]);
但是 Krajee 在这里提到了您自动获得此信息的事实。
上面的每个视图都将直接接收并读取与上面 nodeView 部分中提到的相同的参数（例如，这些视图将以 $node、$modelClass、$action 等形式提供给视图.).此外，views还会接收到$form参数，即ActiveForm实例（来自kartik-v/yii2-widget-activeform）。
所以没有必要采取行动。 $node值在这里生成：
供应商文件夹中 TreeView 中的第 1211 行
public function renderDetail()
{
/**
* @var Tree $modelClass
* @var Tree $node
*/
$modelClass = $this->query->modelClass;
$node = $this->displayValue ? $modelClass::findOne($this->displayValue) : null;
if (empty($node)) {
$node = new $modelClass;
}
渲染细节时创建 $node 值。
我正在研究 Yii2。我使用 kartik tree manager 创建了一棵树。默认情况下，在每个节点上单击它会显示 ID、name 等。但我想显示其他数据。下面是我的代码
<?=
TreeView::widget([
'query' => \common\models\MdcNode::find()->addOrderBy('root, lft'),

正如 Kartik-v 所提到的，如果视图在 frontend\config\main.php.
中的 treeViewSettings 下列出，则 $node 变量由视图继承frontend\views\krajeeproducttree\product.php
<?php
use Yii;
use yii\helpers\Url;
use yii\helpers\Html;
?>
<div class="krajeeproducttree-product">
<br>
<?php
if ($node->product_id > 0){
echo Html::a('<h4>View House Details: ' .$node->name. '</h4>',Url::toRoute(['/product/view','id'=>$node->product_id]));
}
if ($node->productsubcategory_id > 0){
echo Html::a('<h4>View Street Details: ' .$node->name. '</h4>',Url::toRoute(['/productsubcategory/view','id'=>$node->productsubcategory_id]));
}
if ($node->productcategory_id > 0){
echo Html::a('<h4>View Postcode Details: ' .$node->name. '</h4>',Url::toRoute(['/productcategory/view','id'=>$node->productcategory_id]));
}
?>
<br>
</div>
希望这对您或将来的某个人有所帮助。
对费萨尔的回应： 令人困惑...是的，product.php 只有在扩展模型中有指向它们的 table 的外部 ID 键时才有用，这样您就可以 link 带有 [=148= 的节点] 到与 table 关联的 controller/action/id。我这样做是为了避免点击每个节点时显示大量信息。
这是没有外键的控制器：
public function actionPopulate()
{
//remove all data in the database
KrajeeProductTree::deleteAll();
//rebuild the database given data from productcategory ie. postcode, productsubcategory ie. street, product ie. house
//create the root and call it Run
$root = new KrajeeProductTree(['name'=>'Run']);
$root->makeRoot();
//create the postcode nodes
$allpostcodes =[];
$allpostcodes = Productcategory::find()->orderBy('id')->all();
foreach ($allpostcodes as $key => $value)
{
$newpostcodenode = new KrajeeProductTree(['name'=>$allpostcodes[$key]['name']]);
$newpostcodenode->prependTo($root);
$allstreets = [];
$allstreets = Productsubcategory::find()
->where(['productcategory_id'=>$allpostcodes[$key]['id']])
->all();
//create the street nodes associated with this new node
$allhouses = [];
foreach ($allstreets as $key => $value)
{
$newstreetnode = new KrajeeProductTree(['name'=>$allstreets[$key]['name']]);
$newstreetnode->prependTo($newpostcodenode);
$allhouses = Product::find()
->where(['productsubcategory_id'=>$allstreets[$key]['id']])
->andWhere(['productcategory_id'=>$allstreets[$key]['productcategory_id']])
->andWhere(['isactive'=>1])
->all();
//create the house nodes associated with this new steet node
foreach ($allhouses as $key => $value)
{
$newhousenode = new KrajeeProductTree(['name'=>$allhouses[$key]['productnumber']]);
$newhousenode->prependTo($newstreetnode);
}
}
}
return $this->render('index');
}
您会注意到子节点被添加到 ie 之前。 prependTo 父节点。您可以为您打算为其创建树的模块中的所有模型执行此操作。您还会注意到控制器是从 NodeController 扩展而来的。
Here is the format of the tables themselves.
产品类别即。邮政编码有一个 id 自动增量字段。产品子类别即。 streets 也有一个 id autoincrement 字段。此外，Productsubcategory 有一个指向 Productcategory table.
的外键 productcategory_id产品table 即。 houses 有它的 id autoincrement 字段。此外，它还有两个外键，即。 productsubcategory_id 指向产品子类别 table。它还有一个指向产品类别 table.
的外键 productcategory_id这个结构有助于link三个层次，也可以在上面link.
中使用上面模型中使用的Yii2的关系建模结构每条街道 link 对应一个邮政编码，即。 productcategory_id 来自 table Productsubcategory (street) 与 Productcategory table 的 id 字段相同， 此结构还有助于检索每个节点的数据。所以下面的代码在controller links 两级：
$allstreets = Productsubcategory::find()
->where(['productcategory_id'=>$allpostcodes[$key]['id']])
->all();
你在frontend\config\main.php下添加了nodeView，这个有必要吗？我也找不到 ...krajeeproducttree/product 在你的代码中。
nodeView 是一个别名，与指向呈现细节的视图的路径相连，可在 vendor\kartik-v\yii2-tree-manager\src\Module 的第 81 行找到。如果config\main.php下没有提到，默认值为'@kvtree/views/_form'。 This _form is extended by the nodeAddlViews and has to exist if you want to show additional information. _form 可以修改并插入模型的视图下，但必须正确别名，例如@app \ views \krajeeproducttree \ _form.php.
现在我收到错误设置未知 属性: kartik\tree\TreeView::treeViewSettings...
treeViewSettings 不是 \vendor\kartik-v\yii2-tree-manager\src\TreeView 下列出的变量，但是在第 137 行存在 nodeView，在第 153 行存在 nodeAddlViews，因此您可以单独使用这些变量。 IE。不在您选择构建的每个单独树的 treeViewSettings 中。
我在你的代码中也找不到.....krajeeproducttree/product...
是的，控制器 KrajeeproductreeController 应该有一个名为 product 的操作来调用产品视图 product.php。这通常是预期的，但如果您在为 nodeAddlViews 创建的任何视图中执行 var_dump($node)，您将获得 $node 的数组。通常你必须在控制器中传递一个带有渲染的参数，例如。
return $this->render('index', [
'node' => $node
]);
但是 Krajee 在这里提到了您自动获得此信息的事实。
上面的每个视图都将直接接收并读取与上面 nodeView 部分中提到的相同的参数（例如，这些视图将以 $node、$modelClass、$action 等形式提供给视图.).此外，views还会接收到$form参数，即ActiveForm实例（来自kartik-v/yii2-widget-activeform）。
所以没有必要采取行动。 $node值在这里生成：
供应商文件夹中 TreeView 中的第 1211 行
public function renderDetail()
{
/**
* @var Tree $modelClass
* @var Tree $node
*/
$modelClass = $this->query->modelClass;
$node = $this->displayValue ? $modelClass::findOne($this->displayValue) : null;
if (empty($node)) {
$node = new $modelClass;
}
渲染细节时创建 $node 值。
