How to change Wordpress programmatically download folder?

Question

I have a custom theme in which I created a download button where I call the Wordpress Uploader when these buttons are clicked. Something like that:

jQuery('#ahng_blog_upload_button').click(function() { formfield = jQuery('#ahng_blog_upload_image').attr('name'); tb_show('Upload or Select Photo and Click on "Insert into Post"', 'media-upload.php?type=audio&TB_iframe=true'); return false; }); 

Right now, in my functions.php folder, I set where I want the files to download ( http://website.com/wp-content/uploads ), but I want to change the download location depending on which button is clicked .

For example, when the "Download Image" button is clicked, change the download folder to images ( http://website.com/wp-content/uploads/images ), and when you click the "Download MP3" button, change the upload folder to audio ( http://website.com/wp-content/uploads/audio ).

I know that I can upload everything to the default folder that I mentioned earlier, but it’s easier to sort it later if I need to find a specific file using ftp.

Is there a way to do this with jquery and ajax and call a php file that actually returns nothing but makes changes to Upload Dir in wordpress? Or in any other way?

The method used is based on pure WordPress methods not related to jQuery or Ajax.

And I really don’t know which buttons you are referring to ... There was a time when the only button is “Download Media”. If you do not use individual settings.

This WordPress StackExchange answer has other filtering options. Bellow is code configured to filter downloads by media type.

 add_filter('wp_handle_upload_prefilter', 'wpse_25894_handle_upload_prefilter'); add_filter('wp_handle_upload', 'wpse_25894_handle_upload'); function wpse_25894_handle_upload_prefilter( $file ) { add_filter('upload_dir', 'wpse_25894_custom_upload_dir'); return $file; } function wpse_25894_handle_upload( $fileinfo ) { remove_filter('upload_dir', 'wpse_25894_custom_upload_dir'); return $fileinfo; } function wpse_25894_custom_upload_dir($path) { // Determines if uploading from inside a post/page/cpt // If not, default Upload folder is used $use_default_dir = ( isset($_REQUEST['post_id'] ) && $_REQUEST['post_id'] == 0 ) ? true : false; if( !empty( $path['error'] ) || $use_default_dir ) return $path; //error or uploading not from a post/page/cpt // Save uploads in FILETYPE based folders. When using this method, // you may want to change the check for $use_default_dir $extension = substr( strrchr( $_POST['name'], '.' ), 1 ); switch( $extension ) { case 'jpg': case 'png': case 'gif': $customdir = '/images'; break; case 'mp4': case 'm4v': $customdir = '/videos'; break; case 'txt': case 'doc': case 'pdf': $customdir = '/documents'; break; default: $customdir = '/others'; break; } //remove default subdir (year/month) $path['path'] = str_replace($path['subdir'], '', $path['path']); $path['url'] = str_replace($path['subdir'], '', $path['url']); $path['subdir'] = $customdir; $path['path'] .= $customdir; $path['url'] .= $customdir; return $path; }
