blank page after changing upload directory

(@nisr)

hello,
i used this code to change the upload directory according to each custom type:

function wpse_16722_type_upload_dir( $args ) {

    // Get the current post_id
    $id = ( isset( $_REQUEST['post_id'] ) ? $_REQUEST['post_id'] : '' );

    if( $id ) {
       // Set the new path depends on current post_type
       $newdir = '/' . get_post_type( $id );

       $args['path']    = str_replace( $args['subdir'], '', $args['path'] ); //remove default subdir
       $args['url']     = str_replace( $args['subdir'], '', $args['url'] );
       $args['subdir']  = $newdir;
       $args['path']   .= $newdir;
       $args['url']    .= $newdir; 

       return $args;
   }
}
add_filter( 'upload_dir', 'wpse_16722_type_upload_dir' );

this actually works perfectly so i uploaded files using your plugin into their custom directories.
files will be located in :
/wp-content/uploads/custom_post/file2.pdf

but, at the front end, when a visitor try to download the file he got a blank page.
is there any solution please?
kind regards

The download process is done with da_download_attachment function located in plugin folder/includes/functions.php

You’d have to chek what is the filepath you have in this function, right at the top 3 lines (print_r or sth):

$filepath = $uploads['basedir'] . '/' . $attachment;

There’s a filter hook to modify the filepath if needed, but in any case you have to know what is the filepath there.

This can definitely be solved.

thanks for replying 🙂
ok let me be more clear,
the code that i use will put attachments in different upload directories according to each post type. this means, for the publications post type, the attachments will be uploaded to :
/wp-content/uploads/publications/file2.pdf
while for the communications post type they will be uploaded to :
/wp-content/uploads/communications/file3.pdf
So, i need the plugin to make visitors able to download these attachments from any upload directory where they were uploaded to.
i hope you can try the code in any theme function.php and tell me what i have to do. because i looked inside the plugin function.php and i found the line you mentioned but i really didn’t know what to do.

function da_download_attachment($attachment_id = 0)
{
	if(get_post_type($attachment_id) === 'attachment')
	{
		$uploads = wp_upload_dir();
		$attachment = get_post_meta($attachment_id, '_wp_attached_file', true);
		$filepath = $uploads['basedir'].'/'.$attachment;

		if(!file_exists($filepath) || !is_readable($filepath))
			return false;

		// if filename contains folders
		if(($position = strrpos($attachment, '/', 0)) !== false)
			$filename = substr($attachment, $position + 1);
		else
			$filename = $attachment;

		if(ini_get('zlib.output_compression'))
			ini_set('zlib.output_compression', 0);

		header('Content-Type: application/download');
		header('Content-Disposition: attachment; filename='.rawurldecode($filename));
		header('Content-Transfer-Encoding: binary');
		header('Accept-Ranges: bytes');
		header('Cache-control: private');
		header('Pragma: private');
		header('Expires: Mon, 26 Jul 1997 05:00:00 GMT');
		header('Content-Length: '.filesize($filepath));

		if($filepath = fopen($filepath, 'rb'))
		{
			while(!feof($filepath) && (!connection_aborted()))
			{
				echo fread($filepath, 1048576);
				flush();
			}

			fclose($filepath);
		}
		else
			return false;

		update_post_meta($attachment_id, '_da_downloads', (int)get_post_meta($attachment_id, '_da_downloads', true) + 1);

		exit;
	}
	else
		return false;
}

waiting for your reply
best regards
