未定義指數：UsernamesInput在

當我嘗試上傳文本文件時得到「未定義指數：UsernamesInput在」未定義指數：UsernamesInput在

我想看着，我發現一些例子中的問題，但我，他們沒有任何意義我具體代碼

這是我的HTML代碼：

 <div class="container forms"> 
      <form action="verify.php" method="POST"> 
      <div class="col-sm-4"> 
       <fieldset class="form-group"> 
        <label for="exampleTextarea">Emails</label> 
        <textarea class="form-control" id="exampleTextarea" rows="5" placeholder="Emails here..."></textarea> 
       </fieldset> 
       <fieldset class="form-group middle"> 
        <label for="exampleInputFile">Email input</label> 
        <input type="file" class="form-control-file" id="exampleInputFile"> 
        <small class="text-muted">Upload the E-mail adresses for registering</small> 
       </fieldset> 
      </div> 
      <div class="col-sm-4"> 
       <fieldset class="form-group"> 
        <label for="exampleTextarea">Passwords</label> 
        <textarea class="form-control" id="exampleTextarea" rows="5" placeholder="Passwords here..."></textarea> 
       </fieldset> 
       <fieldset class="form-group middle"> 
        <label for="exampleInputFile">Password input</label> 
        <input type="file" class="form-control-file" id="exampleInputFile"> 
        <small class="text-muted">Upload the Passwords for registering</small> 
       </fieldset> 
      </div> 
      <div class="col-sm-4"> 
       <fieldset class="form-group"> 
        <label for="exampleTextarea">Usernames</label> 
        <textarea class="form-control" id="exampleTextarea" rows="5" placeholder="Usernames here..."></textarea> 
       </fieldset> 
       <fieldset class="form-group middle"> 
        <label for="exampleInputFile">Username input</label> 
        <input type="file" name="UsernamesInput" class="form-control-file" id="exampleInputFile"> 
        <small class="text-muted">Upload the Usernames for registering</small> 
       </fieldset> 
      </div> 
      <input type="submit" name="submit" value="Create Accounts!" class="btn btn-info btn-block"> 
      </form> 
    </div>

和我的PHP代碼：

  <?php 

      $_SERVER['REQUEST_METHOD']; 

      $name  = $_FILES['UsernamesInput']['name']; 
      $extention = strtolower(substr($name, strpos($name, '.') + 1)); 
      $type  = $_FILES['UsernamesInput']['type']; 

      //$size = $_FILES['UsernamesInput']['size']; 


      $tmp_name = $_FILES['UsernamesInput']['tmp_name']; 

      if (isset($name)) { 
       if (!empty($name)) { 

        if (($extention == 'txt') and ($type == 'text/plain')) { 

         $location = 'uploads/'; 

         if (move_uploaded_file($tmp_name, $location . $name)) { 
          echo 'Uploaded!'; 
         } else { 
          echo 'There was an error'; 
         } 

        } else { 
         echo 'Error, file must be in text format.'; 
        } 
       } 
      } 



      ?>

由於提前，

我覺得輸入類型=「文件」還需要一個名稱的屬性，它是什麼你在這裏失蹤。 – Maximus2012

你真的上傳了與該字段對應的文件嗎？ – Maximus2012

@ Maximus2012是無所謂我上傳或保留空它不斷返回相同的錯誤 – Naomi

每種類型添加名稱= '文件' 的投入，並嘗試在形式

<form action="verify.php" method="POST" enctype="multipart/form-data"> 
<input type="file" name="UsernamesInput" class="form-control-file" id="exampleInputFile"> 
</form>

你需要在你的HTML表單中添加enctype="multipart/form-data"加入ENCTYPE =「的multipart/form-data的因爲您在HTML中使用輸入類型文件。

<form action="actionFile" method="post" enctype="multipart/form-data">

HTML Form Enctype
