Html Code:
<html><head><title>Sales Rep Maintenance</title></head><?php// Address error handlingini_set('display_errors',1);error_reporting(E_ALL & ~E_NOTICE);// Attempt to Connectif ($connection = @mysql_connect ('localhost', '***', '***')){ print '<p>Successfully connected to MySQL.</p>'; //mysql_close(); // close the connection}else { die('<p>Could not connect to MySQL because: <b>' .mysql_error() .

error_reporting(E_ALL & ~E_NOTICE);
改作
error_reporting(E_ALL);
可能就知道了
把 $row 的关联键改成小写看看
error_reporting(E_ALL & ~E_NOTICE);
改作
error_reporting(E_ALL);
可能就知道了
把 $row 的关联键改成小写看看
我试了, 错误提示为:
Undefined index: submit ... on line 28
Undefined index: submit ... on line 33
28行是 if(!$_REQUEST['submit']) 接受的是表单提交的数据
但你的表单中并没有名为 submit 的控件
楼上正解,给type为submit的input加name=submit
28行是 if(!$_REQUEST['submit']) 接受的是表单提交的数据
但你的表单中并没有名为 submit 的控件
那应该怎么改呢?
