Non Users Delete Posts

How can I allow non users to delete posts?

I am currently using this code:

<?php
  global $wp_query;
  $cat = get_the_category();

  if ($cat[0]->cat_ID == 86){
      $url = get_bloginfo('url');
      echo "<a>ID) . "'>Delete post</a>";
 }
?>

This adds a delete link if the current post is in a certain category. It works perfec开发者_运维百科tly but It requires a user with edit privileges to be logged in. How can I change this to allow for regular, non registered users to delete posts?

Any help is appreciated.

You have two options:

1) Promote non-users into users by giving them a session to uniquely identify them and relate each poster with their posts. This requires additional session storage for non-users.

2) Generate a unique hash for each post and provide in the view page a once-only option to delete the post. Similarly to imgur.com, they can still delete the post if they saved the link but will not be presented again. This saves server state.
