mysqli_stmt_bind_param不能处理时间类型吗？

mysqli_stmt_bind_param($stmt, 'idii', $c, $a, $t, $w);

 1)) ) {		$c = mysqli_real_escape_string ($conn, $trimmed['city']);;	} else {		$errors[] = '请选择区域';	}		if (is_numeric($trimmed['taoshu']) && ($trimmed['taoshu'] > 0)) {		$t = mysqli_real_escape_string ($conn, (int) $trimmed['taoshu']);	} else {		$errors[] = '请输入一个正确的套数';	}	if (is_numeric($trimmed['area']) && ($trimmed['area'] > 0)) {		$a = mysqli_real_escape_string ($conn, (float) $trimmed['area']);	} else {		$errors[] = '请输入一个正确的面积';	}			if (empty($errors)) {		$q = 'INSERT INTO f_chengjiao (city_id, area, taoshu, fang_time, os_time) VALUES (?, ?, ?, ?, ?, NOW())';		$stmt = mysqli_prepare($conn, $q);		mysqli_stmt_bind_param($stmt, 'idii', $c, $a, $t, $w);		mysqli_stmt_execute($stmt);		if (mysqli_stmt_affected_rows($stmt) == 1) {			echo '
这条数据已经被添加

发生下列错误:

出错文件是 'D:\wamp\www\zhuzhai_add.php' 出错行号是 36: mysqli_stmt_bind_param() expects parameter 1 to be mysqli_stmt, boolean givenDate/Time: 9-11-2014 03:52:53Array(    [_GET] => Array        (        )    [_POST] => Array        (            [wdate] => 2014-09-11            [city] => 1            [taoshu] => 50            [area] => 10000            [submit] =>         )    [_COOKIE] => Array        (        )    [_FILES] => Array        (        )    [_ENV] => Array        (        )    [_REQUEST] => Array        (            [wdate] => 2014-09-11            [city] => 1            [taoshu] => 50            [area] => 10000            [submit] =>         )

你的$conn 在哪初始化的？ 且inser 语句的字段与值个数没匹配上吧。

mysqli_stmt_bind_param($stmt, 'idi s', $c, $a, $t, $w);
