【问题描述】：

我在 Yii 框架中使用了 CTreeView，因为我想显示一个用户列表。所有用户都显示在我的树中，但我想将 css 添加到我正在读取节点信息的节点中。
例如：如果我转到用户/视图/[id]，所有用户都会显示树而 [id] 的用户是突出显示的怎么办？

控制器：

 public function actionAjaxFillTree()
{
    // accept only AJAX request (comment this when debugging)
    if (!Yii::app()->request->isAjaxRequest) {
        exit();
    }
    // parse the user input
    $parentId = Yii::app()->user->id;
    if (isset($_GET['root']) && $_GET['root'] !== 'source') {
        $parentId = (int) $_GET['root'];
    }
    // read the data (this could be in a model)
    $children = Yii::app()->db->createCommand(
        "SELECT m1.id, m1.username AS text, m2.id IS NOT NULL AS hasChildren "
        . "FROM psh_users AS m1 LEFT JOIN psh_users AS m2 ON m1.id=m2.parent_id "
        . "WHERE m1.parent_id <=> $parentId "
        . "GROUP BY m1.id ORDER BY m1.username ASC"
    )->queryAll();

    echo str_replace(
        '"hasChildren":"0"',
        '"hasChildren":false',
        CTreeView::saveDataAsJson($children)
    );
}

查看：

<?php
$this->widget(
    'CTreeView',
    array('url' => array('ajaxFillTree'),

        )
);
?>
</div>

阅读是指点击时。对吗？
我不确定，但它可能会有所帮助yiiframework.com/wiki/215/…
@kumar_v 不，当我单击任何用户并转到查看页面时，有一个用户列表，在视图（用户详细信息）页面中有一个所有用户的树，但我想显示突出显示这个用户，我不点击节点树，
@Rafay Zia Mir ，我认为你的建议很好，谢谢，如果我得到好的结果，我就离开这里解决

【解决方案1】：

我可以突出显示相关页面的节点：

 public function actionAjaxFillTree() {
    // accept only AJAX request (comment this when debugging)
    if (!Yii::app()->request->isAjaxRequest) {
        exit();
    }
    $node = $_GET[id];
    // parse the user input

    $parentId = Yii::app()->user->id;
    if (isset($_GET['root']) && $_GET['root'] !== 'source') {
        $parentId = (int) $_GET['root'];
    }
    // read the data (this could be in a model)
    $children = Yii::app()->db->createCommand(
                    "SELECT m1.id, m1.username AS text, m2.id IS NOT NULL AS hasChildren "
                    . "FROM psh_users AS m1 LEFT JOIN psh_users AS m2 ON m1.id=m2.parent_id "
                    . "WHERE m1.parent_id <=> $parentId "
                    . "GROUP BY m1.id ORDER BY m1.username ASC"
            )->queryAll();
    $treedata = array();
    foreach ($children as $child) {
        $options =  ($child['id'] == $node)? array('href' => '#', 'id' => $child['id'], 'class' => 'treenode selected_node'):
        array('href' => '#', 'id' => $child['id'], 'class' => 'treenode');
        $nodeText = CHtml::openTag('a', $options);
        $nodeText.= $child['text'];
        $nodeText.= CHtml::closeTag('a') . "\n";
        $child['text'] = $nodeText;
        $treedata[] = $child;
    }
    echo str_replace(
            '"hasChildren":"0"', '"hasChildren":false', CTreeView::saveDataAsJson(**$treedata**)
    );
}
