PHP表單與非必需的文件上傳

我試圖修復此表單，以使文件上傳一個選項，而不是要求，因爲我不會總是有圖像可用。到目前爲止，這是我從研究中得出的結果，但我仍然收到一條消息，要求提供文件。PHP表單與非必需的文件上傳

else if (isset($_POST['add_news_btn'])) { 
    include 'connect.php'; 
    $newsdate = (isset($_POST['newsdate']) ? $_POST['newsdate'] : null); 
    $newstitle = (isset($_POST['newstitle']) ? $_POST['newstitle'] : null); 
    $newscatagory = (isset($_POST['newscategory']) ? $_POST['newscategory'] : null); 
    $newstext = (isset($_POST['newstext']) ? $_POST['newstext'] : null); 

    // upload file 
    if (!empty($_FILES['newsuploader'])) { 
     if(move_uploaded_file($_FILES["newsuploader"]["tmp_name"], "../media/images/" .$_FILES["newsuploader"]["name"])) 
     echo "Saved"; 
     $imageURL = "media/images/" .$_FILES["newsuploader"]["name"]; 
/* else 
    $imageURL=''; 
*/ 

     if (isset($_POST['display']) && $_POST['display'] == '1') 
     { 
      $stmt = $conn->prepare("INSERT INTO news (date, title, content, newscatagory, imageURL, display_image) VALUES(?, ?, ?, ?, ?, 1)"); 
     } 

     else { 
      $stmt = $conn->prepare("INSERT INTO news (date, title, content, newscatagory, imageURL, display_image) VALUES(?, ?, ?, ?, ?, 0)"); 
     } 

    } else if (empty($_FILES['newsuploader'])){ 
     $imageURL = "media/images/news-logo.png"; 
     $stmt = $conn->prepare("INSERT INTO news (date, title, content, newscatagory, imageURL, display_image) VALUES(?, ?, ?, ?, ?, 0)"); 

    } 
    $stmt->bind_param('sssss', $newsdate, $newstitle, $newstext,  $newscatagory, $imageURL); 
    $stmt->execute(); 
    $stmt->close(); 
    echo "done"; 
} 

}

對應形式

 <form name="news-page" action="" method="POST" enctype="multipart/form-data"> 
      <h1>News</h1> 
      <span id="newstitle"> 
       <p id="newstitle">News Title</p> 
       <input id="title" type="text" name="newstitle" value="News Title"/> 
      </span> 
      <span id="newsdate"> 
       <p>News Date</p> 
       <input id="news_date" type="text" name="newsdate" value="News Date"/>    
      </span> 
      <span id="category"> 
       <p>News Category</p> 
       <input id="newscategory" type="text" name="newscategory" value="News Category"/> 
      </span> 
      <p id="news_info">News Information</p> 
      <textarea id="newsinfo" name="newstext">Bacon ipsum dolor amet turducken boudin sirloin ..</textarea> 
      <div id="newsimage"> 
       <img src/> 
       <p>Insert News Image</p> 
        <label class="myLabel" id="news-image-upload"> 
        <input type="file" required name="newsuploader" id="fileToUpload" /> 
        <span>Select Image</span> 
        </label> 
        <input type="checkbox" name="display" value="1">Display Image 
      <button type="submit" name="add_news_btn">Add News</button> 
      </div> 
      </form>

刪除從所述輸入元件的「必需的」 attribue（形式）。

替換：

<input type="file" required name="newsuploader" id="fileToUpload" />

有了：

<input type="file" name="newsuploader" id="fileToUpload" />

由於它的工作原理 - 由於某種原因，我想我需要改變在PHP的東西。 – Chri
