I made an image uploader in WordPress using the

wp_upload_bits()

function. Here is my code how I do it

 $upload = wp_upload_bits($_FILES['portfolio_img']['name'][$i], null, file_get_contents($_FILES['portfolio_img']['tmp_name'][$i]));
   if(isset($upload['error']) != false ) {
   $portfolio_imgs[] = $upload['url'];
   add_post_meta($id, 'portfolio_imgs', $portfolio_imgs);
   update_post_meta($id, 'portfolio_imgs', $portfolio_imgs);
 }

I would like to allow the administrator to delete the uploaded images in the back end. I made the option and it deletes the meta infos, I can also get the images absolute url, for example:

http://localhost/wordpress/wp-content/uploads/2016/08/road.jpg

However I can't use the the

unlink()

PHP function for absolute URLs. I tried to convert the URLs to relative path but I can't make it work even with if I get a relative path like:

/wp-content/uploads/2016/08/road.jpg

or

wp-content/uploads/2016/08/road.jpg

I always get this error:

Warning: unlink(/wp-content/uploads/2016/08/road.jpg) [function.unlink]: No such file or directory in /home/...

I am really stuck with this any help is appriciated!

  • How do you get URL?

  • I have an array of each URL and I have a for loop to read each value 1 by 1 and do something with it 'for ($d=$delete_length-1; $d > -1; $d--) { if($selected[$d] == "delete") { unlink($current_images[$d]);} }'

Within your code snippet $upload['file'] will contain the full file path to the file. You could save this in the meta so that it's retrievable whenever you want to delete the file.

  • Ah - that's not what your question says. The absolute path will be from your server's filesystem root, not your website's root.

  • Oh - do you have any idea how could I convert this URL: link to something I can use in unlink() function to delete the file?

  • Don't try and convert from the URL, just save $upload['file'] for later.

  • $upload['file'] has the absolute path of the file wp_die($upload['file']); returns: D:\work2016\xampp\htdocs\wordpress/wp-content/uploads/2016/08/road.jpg How do I delete the file using this absolute path?
