使用复选框成功从db中删除多个图像，但不会从文件夹中取消链接文件

Question

我在PHP中使用unlink()函数时遇到问题。我使用了一个复选框来删除图像或上传的视频文件。

从数据库中成功删除多个图像或视频，但不使用qazxsw poi从本地文件夹中删除。

没有错误，但是当我选中所有复选框并按删除时，数据库中的所有文件都将被删除，但只有第一个文件被取消链接。

这是我的代码：

unlink()

Answer 1

尝试

<?php // for delete checked video php script

include('config.php');

if(isset($_POST['delete'])) {
    $checkedCandidates = 0;
    $id = implode(",", $_POST['deletecb']);

    $checkedCandidates = count($id);

    if ($checkedCandidates < 1) {
        echo "<div id=\"errormsg\"> You need to check at least one video for delete. </div>";
        echo "<script>setTimeout(\"location.href = 'video_upload.php';\",3000);</script>";
    } else {
        $result=mysqli_query($connection,"SELECT * FROM video_gallery where id_vid IN($id) and users_name='$login_session'");

        while ($row=mysqli_fetch_assoc($result)) {
            $fname=$row[FILE_NAME];

            $Path="data/58f60f2e09f07_jay/videos/$fname";
            if (file_exists($Path)){
                if (unlink($Path)) {
                    echo "success";
                } else {
                    echo "fail";
                }
            } else {
                echo "file does not exist";
            }
        }
        $query1=mysqli_query($connection,"delete from video_gallery where id_vid IN($id) and users_name='$login_session'");
        if($query1) {
            echo "<div id=\"successmsg\"> delete successfully </div>";
        } else {
            echo "<div id=\"errormsg\"> failed operation!!</div>";
        }
    }
}
?>

并检查文件名的密钥名称在访问数组项时更改此行

print_r($row);

至

$fname=$row[FILE_NAME]; 

Answer 2

用$fname=$row['the actual name of the field']; 替换$Path="data/58f60f2e09f07_jay/videos/$fname";

并用$Path="data/58f60f2e09f07_jay/videos/".$fname;取代$row[FILE_NAME]
