插入数据库错误的问题?问题出在哪里?

数据库 exception 刚开始写留言板,通过mysqlconnect类的insert方法讲留言信息插入数据库
错误信息如下:
Fatal error: Uncaught exception 'Exception' with message ' SQL insert into message(name,addtime,content,reply) values('test14','2013-09-07 01:59:02','and0s8jsfn89233j2r87hyfw','')' in D:\AppServ\www\forum\util\MySqlConnect.class.php

下面是insert方法代码:

public function insert($table_name, $data_array){		$field_array = array();		$value_array = array();		foreach($data_array as $k => $v){			$field_array[] = $k;			if(gettype($v) != "integer"){				$value_array[] = "'".$v."'";			}else{				$value_array[] = $v;			}		}		$sql = "insert into ".$table_name."(".implode(",",$field_array).") values(".implode(",",$value_array).")";		//echo $sql;		//exit();		$boolean = $this->execute($sql);		$this->insertId = mysql_insert_id($this->connection);		return $boolean;	}

$vname = $_POST["name"];	$vcontent = $_POST["content"];	$vaddtime = date("Y-m-d h:i:s");	$vreply = "";	$arr = array("name"=>$vname,"addtime"=>$vaddtime,"content"=>$vcontent,"reply"=>$vreply);	$message = new message;	$done = $message->insert("message", $arr);

回复讨论(解决方案)

不好意思,SQL语句输入的差数有问题.已解决,版主帮忙把帖删了,谢谢!
