Question

我正试图通过点击按钮从服务器下载我的文件。但我无法获得成功。它一次又一次地显示我的错误。这是我的小.htaccess代码和下载文件代码有错误。

内部服务器错误

.htaccess代码在这里

DirectoryIndex index.php

RewriteEngine on
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond $1 !^(index\.php|robots\.txt)

RewriteRule ^(.*)$ index.php?/$1 [L]

下载文件的代码。

$query = "Select * from table_name where id = '".$id."'";

            $sql = mysqli_query($con, $query);

            while($row = mysqli_fetch_array($sql)){

                $path = $row['File_path'];              
                header('content-Disposition: attachment; filename = '.$path.'');
                header('content-type:Documents/content=pdf');
                header('content-length'.filesize($path));
                readfile($path);

我提到这个问题，但它说删除.htaccess文件，但我想保留这个文件。

这是所有类型文件下载的PHP代码：

$link = 'link include file path and filename with extension'

// Grab the file extension
$extension = pathinfo($link,PATHINFO_EXTENSION);
$filename = pathinfo($link,PATHINFO_FILENAME);

// our list of mime types

// Set a default mime if we can't find it

    header( 'Content-Disposition: attachment; filename='.$filename.'.'.$extension);
    header( "Content-Transfer-Encoding: binary" );
}
readfile( $link );

.htaccess文件：

RewriteEngine on
