Question

我正在尝试使用多个SET更新我的SQL数据库。我想要实现的是更新表中的客户记录。例如，客户可能会更改其地址。

这是我的代码：

            <?php
            $con = mysql_connect("localhost","root","");
               if (!$con){
                  die('Could not connect: ' . mysql_error());
               }
                   mysql_select_db("floras", $con);
                   for ($i=count($_POST['id']); $i--;) {
                           $id = $_POST['id'][$i];
                           $custf = $_POST['fname'];
                           $custs = $_POST['sname'];
                           $custe = $_POST['email'];
                           $custp = $_POST['phone'];
                           $custm = $_POST['mobile'];
                           $custa1 = $_POST['add1'];
                           $custa2 = $_POST['add2'];
                           $custt = $_POST['town'];
                           $custc = $_POST['county'];
                           $custpc = $_POST['postc'];
                       $sql="UPDATE tbl_customer SET
                              customer_forename=$custf,
                              customer_surname=$custs,
                              customer_email=$custe,
                              customer_phone=$custp,
                              customer_mobile=$custm,
                              customer_address1=$custa1,
                              customer_address2=$custa2,
                              customer_town=$custt,
                              customer_county=$custc,
                              customer_postcode=$custpc
                            WHERE customer_id=$id";
                }
                if (!mysql_query($sql,$con)){
                   die('Error: ' . mysql_error());
                }
            mysql_close($con); 
            ?>

显然，这已全部通过帖子发送，并且$ _POST变量已在SQL命令之前设置为另一个变量。

当我打开页面时，我得到的错误是：

错误：您的SQL语法出错;查看与您的MySQL服务器版本对应的手册，以便在'1，customer_address2 =地址2，customer_town = Town，customer_county = County，cust'第1行附近使用正确的语法

任何帮助？

谢谢大家！

Answer 1

您需要将字符串变量括在单引号内。您的更新查询将如下所示：

$sql="UPDATE tbl_customer SET customer_forename='$custf', 
customer_surname='$custs',
customer_email='$custe', customer_phone='$custp',customer_mobile='$custm',
customer_address1='$custa1', customer_address2='$custa2',
customer_town='$custt', 
customer_county='$custc', customer_postcode='$custpc' 
WHERE customer_id=$id";

Answer 2

您的查询中有错误。从查询中移除>并添加'单引号

$sql="UPDATE tbl_customer SET `customer_forename`='$custf',
`customer_surname`='$custs',
`customer_email`='$custe', `customer_phone`='$custp',`customer_mobile`='$custm',
`customer_address1`='$custa1', `customer_address2`='$custa2',
`customer_town`='$custt',
`customer_county`='$custc', `customer_postcode`='$custpc' 
 WHERE `customer_id`='$id'"

Answer 3

删除＆gt;来自字段名称＆gt; customer_surname

Answer 4

从字段中删除额外的>符号，并在'单引号内传递值。像这样：

$sql="UPDATE tbl_customer SET customer_forename='$custf', customer_surname='$custs', customer_email='$custe', customer_phone='$custp', customer_mobile='$custm', customer_address1='$custa1', customer_address2='$custa2', customer_town='$custt', customer_county='$custc', customer_postcode='$custpc' WHERE customer_id='$id'"; }

使用多个SET更新SQL数据库？
