Hidden download plugin problem

[vavw]

Hi,

I purchased the Hidden Download plugin today. Unfortunately, I can not get it to work properly.

On my new website I wish to share content in large zipfiles that can be downloaded from my NAS at home. The links to the files are created by my NAS and end in, for example: /nas/filelink.lua?id=1234567890
When downloading a file by pasting the original download link in a browser, the linked zipfile is downloaded in the original format, for example: filename.zip.
However, when creating a hidden download link using the plugin, the downloaded filename is “filelink.lua?id=1234567890” instead of “filename.zip”. The file can not be opened, unless the .zip extension is manually added once the download is complete. The content of the download is unaltered, it is the name of the downloaded file that is the problem caused by the plugin: the original file name of the original file (not the download link) should be maintained, as should the .zip extension.

Is this something that can be fixed in an update?

Thanks,

Victor

It tries to read the filename by using the PHP basename() function. So it needs a direct link to the static file (not to another script which will manage the file):
https://www.php.net/manual/en/function.basename.php

It is likely that function is failing to read the file name. The setup you explained is not a standard one for handling download via PHP system so I am not 100% sure if it will work but it is worth trying the different download method settings offered in the hidden downloads addon. Go to the “Hidden Download” menu in your WP Admin interface. Then try the different URL conversion and download method options to see if it can handle the download better.

Thank you for your fast reply.

The three URL Conversion options (Absolute / Relative / Do not convert) in combination with Download Method 1 all have the same result, as described above.

The same happens with Download Method 2, 4, 5 & 6.

Method 3 gives a Bad Gateway.

Method 7 & 8 add “.html” to the name of the download.

If this can not be fixed by means of a plugin update, can it perhaps be tweaked so that the name of the downloaded file can be entered, converting any unwanted filename (“filelink.lua?id=1234567890”) without an extension to a preset one with the desired extension (“filename.zip”)?

Lets try a little test with some PHP code tweaks to see if it works. We can then add a filter in the addon so it can be customized without modifying the core addon’s code in the future.

1) Open the following file of this addon:

sdm-hidden-downloads/sdm-hd-download-handler.php

2) Find the following line of code in that file:

$file_name = basename($file_path);

3) Replace it with something like the following:

$file_name = basename($file_path);

$file_parts = pathinfo($file_path);
if (empty($file_parts['extension'])){
    //Missing extension. Manually force it to have .zip extension
    $file_name = $file_name . '.zip';
}

Please note that I have written this code from the top of my head. It hasn’t been tested. So make sure to change this code via FTP so you can revert the changes (by replacing with the original file) easily if something goes wrong.

I replaced the code as instructed above but it does not change anything. The download file name remains identical to the NAS file id, without the .zip extension.

In addition (something that also does not fix the problem but perhaps it is something you can look into): I created a 301 redirect to the download file on my NAS and used the “new” link as the download link for SDM. This results in a 502 Bad Gateway – “The proxy server received an invalid response from an upstream server.”

[admin]

Maybe hardcode the name like the following (so it always appends .zip to the file name).

$file_name = basename($file_path);
$file_name = $file_name . '.zip';

Does that make any difference?

Regarding the 502 error, you need to look at the server’s error log to see what exactly is triggering that. The error log will have clue as to what specific function call is failing on this site.

[vavw]

The good news is that the code above adds the .zip extension to the download. So that works.

However, when using the hidden download option [sdm_hidden_download id=”1234″] the name of the downloaded file is still that of the download link, instead of the file.
