将CSV文件导入数据库

Question

我正在使用以下功能将csv文件导入db。 一切正常。 但是我也希望它也插入$_SESSION['userid']与CSV文件。 请帮我。 谢谢

    function csv_file_to_mysql_table($source_file, $target_table, $max_line_length=10000) { 
            if (($handle = fopen("$source_file", "r")) !== FALSE) { 
                $columns = fgetcsv($handle, $max_line_length, ","); 
                foreach ($columns as &$column) { 
                    $column = str_replace(".","",$column); 
                } 
                $insert_query_prefix = "INSERT INTO $target_table (".join(",",$columns).")\nVALUES"; 
                while (($data = fgetcsv($handle, $max_line_length, ",")) !== FALSE) { 
                    while (count($data)<count($columns)) 
                        array_push($data, NULL); 
                    $query = "$insert_query_prefix (".join(",",quote_all_array($data)).");"; 
                    mysql_query($query); 
                } 
                fclose($handle); 
            } 
        } 

        function quote_all_array($values) { 
            foreach ($values as $key=>$value) 
                if (is_array($value)) 
                    $values[$key] = quote_all_array($value); 
                else 
                    $values[$key] = quote_all($value); 
            return $values; 
        } 

        function quote_all($value) { 
            if (is_null($value)) 
                return "NULL"; 

            $value = "'" . mysql_real_escape_string($value) . "'"; 
            return $value; 
        }
        csv_file_to_mysql_table($uploadfile,"import_csv");
        echo "file is imported successfully!";
    }

我想象这样的事情会起作用。 在执行数组连接后，只需追加额外的字段即可。

我不知道您的user_id列叫什么，我只是假设user_id

$insert_query_prefix = "INSERT INTO $target_table (".join(",",$columns).",user_id)\nVALUES";

将user_id值添加到values参数

$query = "$insert_query_prefix (".join(",",quote_all_array($data)).",".$_SESSION['userid'].");";

查找“ ADD HERE” ...，只要在获取列名称后加上它们，然后在建立数组后就将数据添加到数组的末尾...应该就这么简单。

            foreach ($columns as &$column) { 
                $column = str_replace(".","",$column); 
            }
//ADD HERE
$columns[] = "userid";
            $insert_query_prefix = "INSERT INTO $target_table (".join(",",$columns).")\nVALUES"; 
            while (($data = fgetcsv($handle, $max_line_length, ",")) !== FALSE) { 
                while (count($data)<count($columns)) 
                    array_push($data, NULL); 
//ADD HERE
$data[] = $_SESSION['userid']

                $query = "$insert_query_prefix (".join(",",quote_all_array($data)).");"; 
                mysql_query($query);
