问题描述

错误:警告:mysql_query()期望参数1为字符串，第8行的C:\ wamp \ www \ cdij \ editquantity.php中提供的资源

Error:Warning: mysql_query() expects parameter 1 to be string, resource given in C:\wamp\www\cdij\editquantity.php on line 8

这是代码:

<?php
$con=mysql_connect("localhost","root","","test");
$quantity=$_POST['txt_quantity'];
$name=$_POST['Fields'];
$table=$_POST['editwhat'];

$que="UPDATE `material` SET `material_quantity`='".$quantity."' WHERE `material_name`='".$name."'";
mysql_query($con,$que);
mysql_close($con);
?>

推荐答案

您需要在mysql_query函数中交换$ con和$ que参数.

You need to swap the $con and $que paramters in your mysql_query function.
