• PHP框架 Laravel Eloquent ORM 批量插入数据 && 批量更新目前没有


    foreach ($products as $v=>$a)
    {
     $count[] = array('product_name' => $a['name'], 'product_weight' => $a['weight'], 'product_id' => $a['pid'], 'product_price' => $a['price'], 'order_id' => $order->id, 'card_phone' => $user->phone);
    }
    CountOrder::insert($count);
    

    在使用 laravel 的批量插入数据时,

    插入的数据的创建时间却都是 0000000;

    图片描述

    创建时间 和 更新时间字段 如何正常保存呢 ,难道也要在数组里面写入吗?

     
     
     
     

    框架封装好的方法目前是没有的,但是随手google了一下,在stackoverflow上看到一个和你的这个问题非常匹配的回答,以下复制于stackoverflow,原链接http://stackoverflow.com/questions/26133977/laravel-bulk-update
    I have created My Custom function for Multiple Update like update_batch in CodeIgniter.
    Just place this function in any of your model or you can create helper class and place this function in that class:

    //test data
    /*
    $multipleData = array(
       array(
          'title' => 'My title' ,
          'name' => 'My Name 2' ,
          'date' => 'My date 2'
       ),
       array(
          'title' => 'Another title' ,
          'name' => 'Another Name 2' ,
          'date' => 'Another date 2'
       )
    )
    */
    
    /*
     * ----------------------------------
     * update batch 
     * ----------------------------------
     * 
     * multiple update in one query
     *
     * tablename( required | string )
     * multipleData ( required | array of array )
     */
    static function updateBatch($tableName = "", $multipleData = array()){
    
        if( $tableName && !empty($multipleData) ) {
    
            // column or fields to update
            $updateColumn = array_keys($multipleData[0]);
            $referenceColumn = $updateColumn[0]; //e.g id
            unset($updateColumn[0]);
            $whereIn = "";
    
            $q = "UPDATE ".$tableName." SET "; 
            foreach ( $updateColumn as $uColumn ) {
                $q .=  $uColumn." = CASE ";
    
                foreach( $multipleData as $data ) {
                    $q .= "WHEN ".$referenceColumn." = ".$data[$referenceColumn]." THEN '".$data[$uColumn]."' ";
                }
                $q .= "ELSE ".$uColumn." END, ";
            }
            foreach( $multipleData as $data ) {
                $whereIn .= "'".$data[$referenceColumn]."', ";
            }
            $q = rtrim($q, ", ")." WHERE ".$referenceColumn." IN (".  rtrim($whereIn, ', ').")";
    
            // Update  
            return DB::update(DB::raw($q));
    
        } else {
            return false;
        }
    }

    It will Produces:

    UPDATE `mytable` SET `name` = CASE
    WHEN `title` = 'My title' THEN 'My Name 2'
    WHEN `title` = 'Another title' THEN 'Another Name 2'
    ELSE `name` END,
    `date` = CASE 
    WHEN `title` = 'My title' THEN 'My date 2'
    WHEN `title` = 'Another title' THEN 'Another date 2'
    ELSE `date` END
    WHERE `title` IN ('My title','Another title')
