刪除帶圖像的相冊文件夾

Question

我想刪除裏面所有圖像的相冊。存儲的相冊和圖像的路徑是../_uploads/ < album_name>/< image_file>。下面是我的delete_album.php代碼：

if(isset($_GET['album_id']) === true){ 
    $album_id = (int)$_GET['album_id']; 
    $query_album_info = "SELECT `albums`.`album_id`, `albums`.`album_name`, `images`.`image_name`, `images`.`image_ext` 
         FROM `albums` 
         LEFT JOIN `images` ON `albums`.`album_id` = `images`.`album_id` 
         WHERE `albums`.`album_id` = {$album_id} 
         LIMIT 1 "; 
    $album_info = mysql_query($query_album_info, $connection) or die(mysql_error()); 
    $row_album = mysql_fetch_assoc($album_info); 

    $album = $row_album['album_name']; 
    $img_file = $row_album['image_name'] . '.' . $row_album['image_ext']; 

    $images = scandir("../_uploads/{$album}/"); 
    unset($images[0]); 
    unset($images[1]); 
    //echo "<pre>",print_r($images,true),"</pre>"; 

    foreach($images as $image){ 
     unlink("../_uploads/{$album}/{$image_file}"); 
    } 
    if(rmdir("../_uploads/{$album}") === true){ 
     //delete all images of album from database 
     $query_delete_images = "DELETE FROM `images` WHERE `album_id` = {$album_id}"; 
     $delete_images = mysql_query($query_delete_images) or die(mysql_error()); 
     if(mysql_affected_rows() == 1){   
     }else{ 
      redirect_to("albums.php?del_imgs=1"); 
     } 
     //delete album from database 
     $query_delete_album= "DELETE FROM `albums` WHERE `album_id` = {$album_id}"; 
     $delete_album= mysql_query($query_delete_album) or die(mysql_error()); 
     if(mysql_affected_rows() == 1){ 
      redirect_to("albums.php?delete_album=1"); 
     }else{ 
      redirect_to("albums.php?delete_error_album=1"); 
     } 
    }else{ 
     redirect_to("albums.php?rmdir_error=1"); 
    } 

}else{ 
    redirect_to("albums.php"); 
} 

的錯誤信息，我從重定向到albums.php得到的是[我] rmdir_error = 1 [/ I]，所以沒有圖像從數據庫中刪除和文件夾和相冊，所以rmdir功能不起作用，導致圖像仍然存在。任何想法可能是錯誤的？

您在循環中使用了錯誤的變量（$image_file而不是$image）。因此沒有任何東西被刪除，並且當您嘗試撥打rmdir()時，該目錄不是空的。

// Use the correct variable in the loop statement: changed $image to $image_file 
foreach($images as $image_file) { 
    // Don't attempt to remove the current directory or parent 
    // Since scandir() will return those too... 
    if ($image_file !== "." && $image_file !== "..") { 
     unlink("../_uploads/{$album}/{$image_file}"); 
    } 
}
