php - 第 332 行的 fatal error : Call to a member function getId() on a non-object in C:\wamp\www\magentno\lib\Varien\Data\Tree\Dbp. php

Question

我正在使用 Magento 1.8.0.0，我通过本地主机在 WAMP 服务器上安装了一个测试版本，当我想添加类别时，出现下一个错误:

fatal error :在 C:\wamp\www\magentno\lib\Varien\Data\Tree\Dbp.php 中的非对象上调用成员函数 getId() 第 332 行

我还没有开店，因为我需要那个类别。

我已经在出现错误的行中添加了 try and catch 代码。

这是给出错误的代码:

    public function loadEnsuredNodes($category, $rootNode)
{
    $pathIds = $category->getPathIds();
    $rootNodeId = $rootNode->getId();
    $rootNodePath = $rootNode->getData($this->_pathField);

    $select = clone $this->_select;
    $select->order($this->_table.'.'.$this->_orderField . ' ASC');

    if ($pathIds) {
        $condition = $this->_conn->quoteInto("$this->_table.$this->_idField in (?)", $pathIds);
        $select->where($condition);
    }

    $arrNodes = $this->_conn->fetchAll($select);

    if ($arrNodes) {
        $childrenItems = array();
        foreach ($arrNodes as $nodeInfo) {
            $nodeId = $nodeInfo[$this->_idField];
            if ($nodeId<=$rootNodeId) {
                continue;
            }

            $pathToParent = explode('/', $nodeInfo[$this->_pathField]);
            array_pop($pathToParent);
            $pathToParent = implode('/', $pathToParent);
            $childrenItems[$pathToParent][] = $nodeInfo;
        }

        $this->_addChildNodes($childrenItems, $rootNodePath, $rootNode, true);
    }
}

这一行是 killer :

 $rootNodeId = $rootNode->getId();

Answer 1

此问题是由于重建索引问题引起的。您可以运行此查询以解决此问题

INSERT INTO catalog_category_entity(entity_id,entity_type_id,attribute_set_id,parent_id,created_at,updated_at,path,POSITION,level,children_count) 值 (1,3,0,0,'0000-00-00 00:00: 00','2009-02-20 00:25:34','1',1,0,1),(2,3,3,0,'2009-02-20 00:25:34',' 2009-02-20 00:25:34','1/2',1,1,0);插入 catalog_category_entity_int(value_id,entity_type_id,attribute_id,store_id,entity_id,value) VALUES (1,3,32,0,2,1),(2,3,32,1,2,1);插入 catalog_category_entity_varchar(value_id,entity_type_id,attribute_id,store_id,entity_id,value) VALUES (1,3,31,0,1,'Root Catalog'),(2,3,33,0,1,'root-catalog' ),(3,3,31,0,2,'默认类别'),(4,3,39,0,2,'产品'),(5,3,33,0,2,'默认类别');
