如何使用自定义脚本更新Magento数据库中已存在的类别

Question

我已经使用自定义脚本在Magento中创建了类别， 但问题是，当我再次运行相同的URL时，我的脚本会创建另一组相同的类别。因为我想更新现有类别并插入新类别（如果存在于csv。

中）

我的csv结构是：

Category 1,Description,Category 2,Description,Category 3,Description,Category 4,Description

1,COSTUMES,1,ADULTS,1,MENS
1,COSTUMES,1,ADULTS,1,MENS,2,ASIAN
1,COSTUMES,1,ADULTS,1,MENS,3,BIKER
1,COSTUMES,1,ADULTS,1,MENS,1,CAPES & ROBES
1,COSTUMES,1,ADULTS,1,MENS,5,CAVE PEOPLE

提前感谢你们所有人的答案

以下是我创建多级别类别的代码：

define('MAGENTO', realpath(dirname(__FILE__))); 
require_once MAGENTO . '/app/Mage.php';
umask(0);
Mage::app()->setCurrentStore(Mage_Core_Model_App::ADMIN_STORE_ID);
$count = 0;
$file = fopen('export/web categories.csv', 'r');
function odd($var)
{

    $odd = array();

     foreach ($var as $k => $v) {
        if ($k % 2 !== 0) {
            $odd[$k] = $v;
        }
    }
    return $odd;
}
function even($var)
{
    $even = array();
     foreach ($var as $k => $v) {
        if ($k % 2 == 0) {
            $even[$k] = $v;
        }
    }
    return $even;
}

function strcount($str,$sy){
    $ch=  explode($sy, $str);
    return count($ch);
}

$pos=0;
$row_config= array();
$test=array();
$catgoryID=array();
$parID = 1;
while (($line = fgetcsv($file)) !== FALSE) {
    if(!in_array($valtest,$row_config)){
    if($count == 0){
        $count++;
        continue;
    }

    $count++;
    $filterd_data=array_filter($line);
    $odd_cell_data=odd($filterd_data);
    $even_cell_data=even($filterd_data);
   $config=array();
   $string='';
    $intialID=$even_cell_data[0];
    foreach($odd_cell_data as $key=>$val){

        if(!in_array($val,$config)){

            $config[] = $val;
            $data['general']['name'] =$val;
            $data['general']['meta_title'] = "";

            $data['general']['position'] =1 ;
            $storeId = 0;
            $string .=$val.'~';
            if(!array_key_exists($string, $row_config)){
            $catID=createCategory($data, $storeId);
            $catgoryID[$string]=$catID;
            $row_config[$string]=$parID;

            } else {
               $parID =$row_config[$string] ;
                $row_config[$string]=$row_config[$string];
            } 

            if( strcount($string,'~')==2){

             }

           assignCat($catgoryID[$string],$parID);
           $parID = $catgoryID[$string];


            sleep(0.5);
            unset($data);

        }


    }

    } 

}
