为什么<输入=“文件”>模态不能通过图像到PHP

Question

我新秀在PHP和HTML，我有这个模态具有在它，我需要用于插入图像..

if (isset($_POST['add_roomtype_action'])) { 
    require 'script/addRoomType.php'; 
} 

<div class="modal fade" id="add_roomtype_modal" tabindex="-1" role="dialog" 
aria-labelledby="add_roomtype_modal" aria-hidden="true"> 
     <div class="modal-dialog"> 
     <div class="modal-content"> 
     <div class="modal-header"> 
      <button type="button" class="close" data-dismiss="modal" aria- 
hidden="true">&times;</button> 
     <h4 class="modal-title" id="myModalLabel">Add Room Type</h4> 
      </div> 
      <form action="room_management.php" method="post" 
autocomplete="off"> 
      <div class="modal-body"> 

      <input type="hidden" id="upd_roomtype_id" name = 
"add_roomtype_idnm"> 
      <label style="font-size: 10pt">Room Type : </label> 
      <input type="text" id="add_roomtype" name = "add_roomtypenm" 
style="font-size: 10pt" ><br></br> 
      <label style="font-size: 10pt">Rate : </label> 
      <input type="text" id="addupd_rate" name = "add_ratenm" 
style="font-size: 10pt" ><br></br> 
      <label style="font-size: 10pt">Image : </label> 

      <input type="file" id ="add_roomtypeImgid" 
name="add_roomtypeImgnm" accept="image/x-png,image/jpeg"> 

      </div> 

      <div class="modal-footer"> 
      <button type="button" class="btn" data- 
dismiss="modal">Close</button> 
      <button type="submit" class="btn" id = "add_roomtype_action" 
name = "add_roomtype_action">Add</button> 
      </div>  
      </form> 
     </div> 
     </div> 
    </div> 

，这是PHP文件，该文件的模式将调用

<?php 

    $servername = "localhost"; 
    $username = "root"; 
    $password = ""; 
    $dbname = "afgroms"; 


    $conn = new mysqli($servername, $username, $password, $dbname); 

    if ($conn->connect_error) { 
    die("Connection failed: " . $conn->connect_error); 
    } 

    if(isset($_POST['add_roomtype_action'])){ 
    $roomtypeid = $_POST['add_roomtype_idnm']; 
    $roomtype = $_POST['add_roomtypenm']; 
    $rate = $_POST['add_ratenm']; 
    $file = $_FILES['add_roomtypeImgnm']; 
    $fileName = $file['name']; 
    $fileTmpName = $file['tmp_name']; 
    $fileSize = $file['size']; 
    $fileError = $file['error']; 
    $fileType = $file['type']; 






    $fileExt = explode('.', $fileName); 
    $fileActualExt = strtolower(end($fileExt)); 

    $allowed = array('jpg','jpeg','png'); 

    if(in_array($fileActualExt, $allowed)){ 
     if($fileError === 0) 
     { 
      if ($fileSize > 500000) { 
       mysql_query("UPDATE `tbl_roomtype` SET `RoomType` = 
'$roomtype', `Rate` = '$rate', `Image` = '$img' WHERE RoomTypeID = 
".$roomtypeid); 
       echo "<script>"; 
     echo "alert(\"Successfully Added!\");"; 
     echo "</script>"; 
      }else{ 
       echo "<script>"; 
     echo "alert(\"File size too big!\");"; 
     echo "</script>"; 
      } 
     }else 
     { 
     echo "<script>"; 
     echo "alert(\"There was an error\");"; 
     echo "</script>"; 
     } 

    }else 
    { 
     echo "<script>"; 
     echo "alert(\"You cannot upload this type of file\");"; 
     echo "</script>"; 

    } 
    } 
?> 

，但这个错误继续发生：注意：未定义指数：add_roomtypeImgnm ... 帮我在这里的家伙，我不知道什么问题。我已经试图改变我的名字和身份证，同样的错误不断发生。

您无法发布文件的原因不是您的模式对话框，而是您的表单中没有使用enctype="multipart/form-data"这一事实。

尝试这样，它应该工作。
