保存在DB的同時

Question

我有一個基本的圖片上傳這是工作不錯，但現在我需要將其保存在我的MySQL數據庫3圖像不是唯一的一個，我怎麼能保存3個圖像相同的形式用3個圖像我的上傳腳本？

我需要保存3個圖像，因爲是我第一個博客文章，我想顯示3個圖像預覽滑塊，是因爲這一點，我需要保存3個圖像相同的ID。

另一種認爲，如何才能挽救一個或兩個不上傳腳本給我的錯誤，因爲一個或兩個，甚至是三個文件的上傳是空的？

在這裏，我告訴你我的上傳腳本：

<?php 
    require_once("connection.php"); 
    require_once("settings.php"); 
    $alert = ""; 
    if(isset($_FILES['foto_ser1'])) { 
     $extension = pathinfo($_FILES['foto_ser1']['name']); 
     $extension = $extension["extension"]; 
     $allowed_paths = explode(", ", $allowed_ext); 
     $valid = 0; 
     for($i = 0; $i < count($allowed_paths); $i++) { 
      if ($allowed_paths[$i] == "$extension") { 
       $valid = 1; 
      } 
     } 
     if ($valid == 1 && $_FILES["foto_ser1"]["size"] <= $max_weight) { 
      if (file_exists("../assets/img/servicios/" . $_FILES["foto_ser1"]["name"])) { 
       $alert = '<p class="error">' . $_FILES["foto_ser1"]["name"] . ' El nombre del archivo ya existe!' . '</p>'; 
      } else { 
       move_uploaded_file($_FILES["foto_ser1"]["tmp_name"], "../assets/img/servicios/" . $_FILES["foto_ser1"]["name"]); 
       $save1 = $_FILES["foto_ser1"]["name"]; 
       $statement = $conn->prepare("INSERT INTO SERVICIOS (titulo, descripcion, categoria, foto_ser1, foto_ser2, foto_ser3) VALUES (?, ?, ?, ?, ?, ?)"); 
       if ($statement->execute(array($_POST['titulo'],$_POST['descripcion'],$_POST['categoria'],$save1,$save2,$save3))); 
       $dbSuccess = true; 
       $alert = '<p class="ok">' . ' Servicio agregado satisfactoriamente!' . '</p>'; 
       $dbh = null; 
      } 
     } else { 
      $alert = '<p class="error">' . ' Tipo de archivo inv&aacute;lido!' . '</p>'; 
     } 
    } 
?> 

形式page.php文件：

      <?php echo $alert1; ?>

新代碼：

Answer 1

您需要進行上傳處理。現在你的代碼只是假設所有的上傳都會成功。事實上，它假設永遠不會成爲一個上傳。

總之，你需要的是這樣的：

for ($i = 1; $i <= 3; $i++) { 
    if ($_FILES["foto_ser{$i}"]['error'] === UPLOAD_ERR_OK) { 
     ...file #$i has succeeded... 
    } 
} 

您的代碼也是相當危險的 - 你直接使用用戶提供的['name']參數在move_uploaded_files通話，它允許惡意用戶亂寫一個他們在你的服務器上任意選擇的文件。
