我是 php 新手,并试图开发一个登录脚本,但是当我输入值时它不起作用。我什至找不到错误,因为当我点击提交时,它只会刷新页面
这是我的代码
<?php include "../utilities/config.php";
foreach($_GET as $key=>$value)
{
${$key} = trim($value);
}
$error = '';
if($checking_member_availability == 'yes'){
if(empty($user_name)){
$error .= "Please enter user name.<br />";
}
if(empty($password)){
$error .= "Please enter password.<br />";
}
if(empty($error)){
$sql = "select * from `".SITE_TABLE_PREFIX."user` where email='".$user_name."' and pwd='".$password."'";
$resultUser = mysql_query($sql) or die(mysql_error().$sql);
if(mysql_num_rows($resultUser)>0){
$rowUser = mysql_fetch_array($resultUser);
$error .= '';
$_SESSION['email']=$user_name;
}else{
$error .= "Please check Email and Password.";
}
}
if(empty($error)){
echo "myaccount.php";
}
else{
echo "<font color='#A01D49'>$error</font>";
}
}
?>
请任何人都可以帮助我我花了很多时间都没有成功
这是html代码
<script type="text/javascript" language="javascript">
function validation()
{
var password = trim(document.form1.password.value);
var user_name = trim(document.form1.user_name.value);
var type = trim(document.form1.type.value);
http.open("GET", "processor.php?checking_member_availability=yes&password="+
escape(password)+"&user_name="+ escape(user_name)+"&type=" + escape(type) , true);
http.onreadystatechange = handleHttpResponse;
http.send(null);
return false;
}
</script>
