php - 当我们从数据库中删除图像时，图像无法从文件夹中删除

Question

我正在尝试从记录图像的数据库和文件夹中删除图像。这是我的代码。问题是如果我提交删除查询然后数据库图像被删除但文件夹图像仍然存在。请帮忙。

if(empty($_POST)===false)
       {
        if(empty($_POST['events'])===true||empty($_POST['description'])===true||empty($_FILES['images']['name']))
        {
?>                    
                    <div class="alert alert-warning alert-dismissible text-center" role="alert">
                    <span class="glyphicon glyphicon-exclamation-sign" aria-hidden="true"></span>Add some events and descriptions
                    </div>
 <?php       
        }  
        else
    if (isset($_POST["events"])&&isset($_POST["description"])) 
        {
            $event_title=$_POST["events"];
            $description=$_POST["description"];
            $filetmp=$_FILES["images"]["tmp_name"];
            $filename=$_FILES["images"]["name"];
            $filetype=$_FILES["images"]["type"];
            $filepath= "photo1/".$filename;
            move_uploaded_file( $filetmp,$filepath);
            $data=array($page_id,$event_title,$description,$filepath);
            $add=add_data_event($data);
            if($add)
                {          
                    header('location:hotel1_galery_event.php?page_id=1 && msg=Add Offers Successfully'); 
                }
            foreach ($errors as $value)
                {
                    echo $value;
                }
        }
    }

    if(isset($_GET['id']))
        {
            $id=$_GET['id'];

Answer 1

在您的案例中，有两个选项可以删除图像。

首先

像下面这样在url中发送带有完整路径的文件名

<a href="hotel1_galery_event.php?page_id=1&&id=<?php echo $val['event_id'];  ?> && msg=Delete Successfully &file=<?php echo $filepath ">

其中 $filepath= "photo1/".$filename;

第二

根据id从数据库中获取文件的路径，然后删除它。
