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>

Answer 1

您可以包括的原初語境您問題？什麼是錯誤/不正確的行爲？這是託管在某處測試嗎？

從我可以告訴它基於

if(empty($error)){ 
    echo "myaccount.php"; 
} 

此行只輸出「myaccount.php」不是重定向在成功登錄。我相信如果你改變你的空（$ error）檢查包含重定向，它應該工作。

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; 

     /* Redirect user if successful login */ 
     header('Location: myaccount.php'); 
    } else { 
     $error .= "Please check Email and Password."; 
}
