如果一個textfiled爲空，pdo插入不起作用

Question

我已經在下面發佈了我的代碼。我試圖將數據插入數據庫。問題是如果用戶沒有選擇一個文本字段，它不會將剩餘的數據插入到數據庫中。例如，我有一個註冊表單。用戶應填寫所有文本框，但userprofilepicture是可選的。所以，如果用戶沒有選擇他/她的圖像文件，它不會插入剩餘的數據。如果一個文本字段爲空，如何插入數據？

if(isset($_POST['sub_values'])) 
{ 
    $c_uname = $_POST['uname']; 
    // some codes 
    // some codes 
    // some codes 
    $token = md5(uniqid(mt_rand(), true)); 

    if (isset($_FILES['image']) && $_FILES['image']['size'] > 0) 
    { 
     $tmpName = $_FILES['image']['tmp_name']; 

     $fp = fopen($tmpName, 'r'); 
     $data = fread($fp, filesize($tmpName)); 
     $data = addslashes($data); 
     fclose($fp); 

     try 
     { 
      $stmt = $conn->prepare("INSERT INTO ebusers (UserName, UserPassword, ConfirmPassword, FirstName, LastName, Address, UserEmail, UserPhone, Gender, UserProfilePicture, CreatedOn, isAdmin, UserSecretID) VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?, '$data', NOW(), ?, ?)"); 
      $conn->errorInfo(); 
      $stmt->bindParam('1', $c_uname, PDO::PARAM_STR); 
      $stmt->bindParam('2', $c_pwd, PDO::PARAM_STR); 
      $stmt->bindParam('3', $c_cpwd, PDO::PARAM_STR); 
      $stmt->bindParam('4', $c_name, PDO::PARAM_STR); 
      $stmt->bindParam('5', $c_lname, PDO::PARAM_STR); 
      $stmt->bindParam('6', $c_address, PDO::PARAM_STR); 
      $stmt->bindParam('7', $c_email, PDO::PARAM_STR); 
      $stmt->bindParam('8', $c_phone, PDO::PARAM_STR); 
      $stmt->bindParam('9', $c_fm, PDO::PARAM_STR); 
      $stmt->bindParam('10', $type, PDO::PARAM_STR); 
      $stmt->bindParam('11', $token, PDO::PARAM_STR); 
      $stmt->execute(); 
     } 
     catch(PDOException $e) 
     { 
      'Error : ' .$e->getMessage(); 
     } 
     } 

     if($stmt) 
     { 
      echo "<script> alert('Registration successfully completed. You can login now'); </script>"; 
      echo "<script> location.href='index.php' </script>"; 
     } 
     else 
     { 
      echo "<script> alert('Registration Unsuccessfull. Try again or contact your administrator'); </script>"; 
      echo "<script> location.href='createuser.php' </script>"; 
     } 

}

    `UserID` int(11) NOT NULL AUTO_INCREMENT, 
    `UserName` char(25) NOT NULL,

你的INSERT語句如下塊內：

if (isset($_FILES['image']) && $_FILES['image']['size'] > 0) 

意義，如果沒有設置，它永遠不會運行INSERT語句。

我會更新的代碼是這樣的：

if (isset($_FILES['image']) && $_FILES['image']['size'] > 0) { 
    //do your stuff in here 
    //etc etc 
    $data = addslashes($data); 
} else { 
    $data = NULL; 
} 

再經過運行你的INSERT語句。
