从远程服务器和localhost上的PHP中的目录中删除图像文件

Question

我试图弄清楚如何使用 summernote 来自远程服务器和localhost的目录文件夹。

因此，图像成功地从SummerNote编辑器上传，并通过目录路径找到：

C:/xampp/htdocs/user/blog/uploads/img-uploads/154_20220702.png

和c：\ xampp \ htdocs \ user \ user \ blog \ admin \ admin \ editor \ editor \ editor \ editor-dlete.php代码>代码：

<?php
    $src  = $_POST['src']; 
    $path = "../uploads/img-uploads/";
    $dir = basename($path);
    $file_name = str_replace($dir, '', $src);
    unlink($file_name);
    if ($file_name) {          
        echo 'File Delete Successfully';
    }
?>

或

$src  = $_POST['src'];
$dir = "../uploads/img-uploads/";
$file_name = str_replace($dir, '', $src);
unlink($file_name);
if ($file_name) {
    echo 'File Delete Successfully';
}

警告：unlink（）：http不允许在 C：\ Xampp \ htdocs \ user \ blog \ admin \ editor \ editor-deiter.php

$src  = $_POST['src'];
$dir = "../uploads/img-uploads/";
$file_name = str_replace($dir, '', $src);
unlink($_SERVER['DOCUMENT_ROOT'] . $file_name);
if ($file_name) {
    echo 'File Delete Successfully';
} 

localhost正确的路径必须为c：/xampp/htdocs/blog/uploads/img-uploads/img-uploads/154_20220702.png，但是使用Unlink（$ _ server ['document_root']。'/'。 $ file_name）;该路径包含额外的http：// localhost/user/ in c：/xampp/htdocs/http：// http：// localhost/user/blog/uploads/uploads/uploads/http：/ img-uploads/154_20220702.png

警告： unlink（c：/xampp/htdocshttp：//localhost/user/blog/uploads/img-uploads/154_20220702.png）： 没有这样的文件或目录 C：\ Xampp \ htdocs \ user \ blog \ admin \ editor \ editor-deiter.php

文件删除成功

jquery-3.6.0.min.js：5177 xhr完成加载：邮局 “ http：//localhost/user/blog/admin/editor-delete.php”。

我无法完全测试此问题，但是我认为您可以更改editor-dlete.php这样的脚本。从问题中引用的路径来判断，您需要通过将遍历文件结构横穿文件结构的uploads/img-uploads so code> chdir和>来构建绝对路径。 GetCWD是两个有用的功能。代码中的注释显示了我的意思。

显示文件成功删除的代码片段是基于一个变量，该变量始终是正确的（有效），而不是来自实际Unlink操作的更有意义的结果，因此应该使用返回的值来分叉您的程序逻辑。

<?php

    /* 
        C:\xampp\htdocs\user\blog\admin\editor-delete.php
        
        so:
        
        chdir('../') leads to C:\xampp\htdocs\user\blog\
        chdir('../uploads/img-uploads') should lead to C:\xampp\htdocs\user\blog\uploads\img-uploads
    */
    
    
    if( isset( $_POST['src'] ) ){
    
        # Change working directory for current script operations
        # - go up one level out of "admin" and into the uploads folder.
        
        chdir('../uploads/img-uploads');
        
        
        # default value for use later in output message
        $status=false;
        
        # construct the full path to local file using getcwd() to find working directory.
        $path=sprintf( '%s/%s', getcwd(), basename( $_POST['src'] ) );
        
        # if the file exists - delete it or warn ( inspect the path! )
        if( file_exists( $path ) )$status=@unlink( $path );
        else exit( sprintf( 'Unable to find file: "%s"', $path ) );
        
        # prevent cached results tainting file checks
        clearstatcache();
        
        
        echo $status ? 'File deleted successfully' : 'Sorry, that file could not be deleted';
    }
