如果（$ _server request_method == post）在表單發佈時不起作用

我有一個註冊表單，我在我的項目中使用了securimage captcha。當我想session_start();後session_start();如print_r($_post)結果是array()但當我評論所有if條件，這是工作，爲什麼？當我提交表單此頁面，但這種情況並不只提交頁面刷新：

if ($_server request_method == post)//stop here don't go inside if condition

這是我register.php頁面代碼：

<?PHP 
    session_start(); 


if ($_SERVER['REQUEST_METHOD'] == 'POST') 
{ 
    include_once dirname(__FILE__).'/process/dbconfig.php'; 

    $flag=true; 
    echo"Asb"; 
    if(isset($_POST['captcha_code'])){ 
     include_once dirname(__FILE__) . '/captcha/securimage.php'; 
     $captcha = $_POST['captcha_code']; 
     $image = new Securimage(); 

     echo $_POST['captcha_code']; 
     if ($image->check($_POST['captcha_code'] ) == false) { 
      $flag=false; 
      $_SESSION['caperr']='Invalid captcha code'; 
      //$err='Invalid captcha code'; 
      header('Location: '.'reister.php'); 
     } 
     //print_r($_SESSION['caperr']); 
     if(isset($_POST['firstname']) && isset($_POST['lastname']) && isset($_POST['username']) && isset($_POST['password1']) 
      && isset($_POST['password2']) && isset($_POST['day']) && isset($_POST['year']) && isset($_POST['month']) 
      && isset($_POST['cell']) && isset($_POST['agree']) && isset($_POST['gen']) && ($_POST['password1']==$_POST['password2']) && $flag && isset($_POST['agree'])){ 

      $conn = new PDO("mysql:host=$host;dbname=$dbname", $username, $password); 
      $sql = $conn->prepare('Insert into users(firstname,lastname,username,password,birthday,gender,phone)values(:firstname,:lastname,:user,:pass,:birth,:gen,:phone)'); 
      $user=$_POST['username']; 
      $firstname=$_POST['firstname']; 
      $lastname=$_POST['lastname']; 
      $pass=md5($_POST['password1']); 
      $birth=$_POST['day'].'-'.$_POST['month'].'-'.$_POST['year']; 
      $gen=$_POST['gen']; 
      $phone=$_POST['cell']; 

      $sql->bindParam(':user',$user,PDO::PARAM_STR,60); 
      $sql->bindParam(':firstname',$firstname,PDO::PARAM_STR,50); 
      $sql->bindParam(':lastname',$lastname,PDO::PARAM_STR,80); 
      $sql->bindParam(':pass',$pass,PDO::PARAM_STR,60); 
      $sql->bindParam(':gen',$gen,PDO::PARAM_BOOL); 
      $sql->bindParam(':birth',$birth,PDO::PARAM_STR,10); 
      $sql->bindParam(':phone',$phone,PDO::PARAM_STR,11); 
      if($sql->execute()){ 
       $_SESSION['success']='Your register is successful! '; 
      } 
     } 
     else{ 
      if(!($_POST['password1']==$_POST['password2'])){ 
       $_SESSION['errsubmitp']='Your passwords must same!'; 
      } 
      else 
       $_SESSION['errsubmit']='Please fill all inputs!'; 
      $_SESSION['caperr']='Invalid captcha code'; 

      header('Location: '.'reister.php'); 
     } 
    } 
    else{ 
     echo "uuuuuuuuuuuuuuuuuuu"; 
     $_SESSION['captchafill']='Please Fill captcha code'; 
     header('Location: '.'reister.php'); 

    } 
}

我看到同樣的問題，但任何的主題有我的問題答案。請幫我解決這個問題。 我贊同var_dump($_SERVER)if ($_SERVER['REQUEST_METHOD'] == 'post')之前，這是我的結果：

'if（$ _server request_method == post）'←這是你的代碼嗎？試試'if（$ _SERVER ['REQUEST_METHOD'] =='POST'）'。 –

+0

如果工作，我將'POST'更改爲小寫，但沒有在結果中回顯任何內容！ – Farshid

+0

你也加了引號嗎？如果您看到一個空白頁面，PHP可能會由於解析錯誤而中止。檢查你的服務器的錯誤日誌，看看有沒有錯誤報告。另外，將'error_reporting（E_ALL）'行添加到您的PHP腳本的頂部。 –

PHP的字符串比較是區分大小寫的。既然你有method="post"，你會得到$_SERVER['REQUEST_METHOD']post，並POST == post是false：

php > var_dump('POST' == 'post'); 
bool(false)

我測試過，但不迴應任何事 – Farshid

+1

所以基本調試：'var_dump（$ _ SERVER ['REQUEST_METHOD']）'看看你真的得到了什麼。 –

+0

我將結果添加到我的問題！ – Farshid

也許嘗試IF

之前呼應你 $_SERVER['REQUEST_METHOD']變量

OR var_dump($_SERVER)和檢查什麼是錯的這個數組中 - 也許您的服務器不設置REQUEST_METHOD關鍵

或嘗試：

if(count($_POST)){/*....*/};
