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，则删除数据库图像但仍保留文件夹图像。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'];
            delete_event1($id);
            unlink($_GET['file']);
            header('location:hotel1_galery_event.php?page_id=1 && msg=Delete Successfully');
        }
    $data1=get_all_event($page_id);
?>

Answer 1

在您的案例中有两种删除图像的选项。

第一

在网址中发送带有完整路径的文件名，如下所示

<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

使用其ID从数据库中获取文件路径，然后将其删除。

当我们从数据库中删除图像时，图像无法从文件夹中删除
