Cookie複選框故障

當我勾選複選框（cookie）並按登錄時，它沒有標題到成員頁面。它的頭部索引頁面（當前頁面）。Cookie複選框故障

，但是當我再次點擊複選框（餅乾），然後按日誌這頭到會員頁面

有人能幫助我哪裏出了問題？

<?PHP 
session_start(); 

function loggedin(){ 
    if(isset($_SESSION['log_email']) || isset($_COOKIE['log_email'])){ 
    $loggedin=TRUE; 
    return $loggedin; 
    } 
} 

$log_email=""; 

if(loggedin()){ 
header("Location:member.php");} 

if(isset($_POST['login'])){ 

    $log_email=strtolower($_POST['log_email']); 
    $log_password=$_POST['log_password']; 

    if(isset($_POST['cookie'])){ 
    $cookie=$_POST['cookie']; 
    } 


    if($log_email && $log_password){ 
     $connect=mysql_connect("localhost", "root", ""); 
     $database=mysql_select_db("phplogin", $connect); 

     $SQL=mysql_query("SELECT * FROM users WHERE email='$log_email'"); 
     $numrows=mysql_num_rows($SQL); 

     if($numrows!=0){ 
      while($result=mysql_fetch_assoc($SQL)){ 
       $db_email=$result['email']; 
       $db_password=$result['password']; 
       $db_firstname=$result['firstname']; 
       $db_lastname=$result['lastname']; 
      } 

      if($log_email==$db_email && md5($log_password)==$db_password){  
        if($cookie){ 
         setcookie("log_email", $log_email, time()+7200); 
        } 
        else{ 
        $_SESSION['log_email']=$log_email; 
        header("location:member.php"); 
        exit(); 
        } 
      } 
      else{echo"wrong username or password";} 
     } 
     else{echo "Can't find the user";} 
    } 
    else{echo "Please enter email or password";} 
}

不要HTML或其他輸出之前打印發送標題。 – MrCode

你<?php打開之前，你開始<html>此頁面，更多的數據。只有在沒有輸出到瀏覽器的情況下，頁眉才能正常工作，所以這不會起作用（除非在顯示的代碼之前，頁面上有某種輸出緩衝處於活動狀態）。

只需從<?php開始，然後移動<html>和其他標籤（包括換行符）在php代碼之後檢查登錄。

然後，而不是與echo直接outputing的錯誤信息，將它們存儲在像$error = "wrong username or password";一個變種，然後在HTML代碼稍後打印<?php echo $error; ?>

<?PHP 
    session_start(); 

    function loggedin(){ 
     if(isset($_SESSION['log_email']) || isset($_COOKIE['log_email'])){ 
     $loggedin=TRUE; 
     return $loggedin; 
     } 
    } 

    $log_email=""; 
    $error = ""; 

    if(loggedin()){ 
    header("Location:member.php");} 

    if(isset($_POST['login'])){ 

     $log_email=strtolower($_POST['log_email']); 
     $log_password=$_POST['log_password']; 

     if(isset($_POST['cookie'])){ 
     $cookie=$_POST['cookie']; 
     } 


     if($log_email && $log_password){ 
      $connect=mysql_connect("localhost", "root", ""); 
      $database=mysql_select_db("phplogin", $connect); 

      $SQL=mysql_query("SELECT * FROM users WHERE email='$log_email'"); 
      $numrows=mysql_num_rows($SQL);
