change default upload for certain file types

Hi @greencrest
Yes, it is possible to change the default upload directory for specific file types in WordPress. You can use the wp_handle_upload_prefilter filter to modify the default upload directory based on the file type.

Here is an example of how you can use this filter to change the default upload directory for PDF files:

add_filter( 'wp_handle_upload_prefilter', 'custom_upload_directory' );

function custom_upload_directory( $file ) {
    // Check if the file is a PDF
    if ( $file['type'] == 'application/pdf' ) {
        // Set the upload directory to a custom location
        $file['url'] = '/wp-content/uploads/pdfs/' . $file['name'];
        $file['error'] = false;
    }
 
    return $file;
}

This code will check if the uploaded file is a PDF. It will set the upload directory to a custom location for PDF files if it is. All other file types will continue to be uploaded to the default WordPress upload directory.

You can modify this code to change the default upload directory for other file types or to specify multiple custom upload directories based on different file types. Give it a try, and let me know how that goes! 😄
