Custom location for pdf file uploads

In wordpress I wanted all images to be uploaded to /images directory and all files (pdf etc) to be uploaded to /files directory, so that they matched the directory structure from a previous CMS I was moving to wordpress.

So I added:

define( 'UPLOADS', 'images');

to the wordpress config.php file, now all files get uploaded to /images and not the default /uploads directory in wordpress. This is regarless of whether they are a image or pdf file.

I then used the below code in my themes functions.php file.

The below code detects when a pdf file is being uploaded, however it puts it in a subdirectory of the /images directory I declared in the wordpress config.php file using - define( 'UPLOADS', 'images');

How would I adjust the below code to make the pdf file be uploaded to /files directory and not /images/files as is the case at the moment.

Any help would be appreciated.

<?php
/* 
 * Change upload directory for PDF files 
 * Only works in WordPress 3.3+
 */

add_filter('wp_handle_upload_prefilter', 'wpse47415_pre_upload');
add_filter('wp_handle_upload', 'wpse47415_post_upload');

function wpse47415_pre_upload($file){
    add_filter('upload_dir', 'wpse47415_custom_upload_dir');
    return $file;
}

function wpse47415_post_upload($fileinfo){
    remove_filter('upload_dir', 'wpse47415_custom_upload_dir');
    return $fileinfo;
}

function wpse47415_custom_upload_dir($path){    
    $extension = substr(strrchr($_POST['name'],'.'),1);
    if(!empty($path['error']) ||  $extension != 'pdf') { return $path; } //error or other filetype; do nothing. 
    $customdir = '/files';
    $path['path']    = str_replace($path['subdir'], '', $path['path']); //remove default subdir (year/month)
    $path['url']     = str_replace($path['subdir'], '', $path['url']);      
    $path['subdir']  = $customdir;
    $path['path']   .= $customdir; 
    $path['url']    .= $customdir;  
    return $path;
}

What happens if you change the value of $customdir to '../files' ?

Thanks Joel

If I change $customdir to '../files'

the path in the wordpress admin area file url is outputted as /images/../files/pdf-file-name.pdf

Of course, what a wally I am!

I'm probably overcomplicating it, but you could try using the dirname function to set $path['path'] up a level before appending the $customdir.

Hi Joel

I've been struggling with this for a few days now and not getting anywhere.

Is there any chance you could give an example of the code for the above solution you suggested?

Thanks
