Aloha，我有一个下载按钮，当下载图像时，它使用会话（路径）进行分配。 然后我删除了之前使用的图片，但是当图像名称相同时，"取消链接（$_SESSION['图片']）;"会删除它们 - 我想每次删除一个......像这样的东西"取消链接（$_SESSION['图片'] <1）;"不起作用。请帮忙：）， 阿罗哈
这是保存图片的代码。
session_start();
$filename = $_FILES["picture"]["tmp_name"];
$destination = "upload/" . $_FILES["picture"]["name"];
move_uploaded_file($filename, $destination); //save uploaded picture in your directory
$_SESSION['picture'] = $destination;
我们已经说过了。从上传文件开始
session_start();
$filename = $_FILES["picture"]["tmp_name"];
//Cutted the file name from the $destination
$destination = "upload/";
//Insert Into DB the info.
//Query Similar To
$sql = "INSERT INTO mytable (filename) VALUES (".$filename.")";
//Get from DB the ID generated.
$sql2 = "SELECT id FROM mytable WHERE filename = '".$filename."'";
//Fetch the data into a $filenameNew var
move_uploaded_file($filename, $destination.$filenameNew); //save uploaded picture in your directory with the db id
$_SESSION['picture'] = $destination.$filenameNew;
改为删除
$sql2 = "SELECT id FROM mytable WHERE ..."; //Get the id name of the file
//put id on a var - $toUnlink
unlink($toUnlink);
$sqlDelete = "DELETE FROM mytable WHERE id = '".$toUnlink."'";
这是一个工作链。您需要做一些工作才能根据您的应用程序使其正常工作。
