If you come to this post, it is highly possible that yo are already annoyed by the Trash feature of WordPress that was introduced in its version 2.9.
I personally find it very helpful in live sites but I believe no one than me is annoyed most by it on development site. However, WordPress is always sweet and its programmers has longer nose. So they put a configurable option to adjust it.
All you need is to add a line in wp-config.php file. You will need to add a constant like:
define('EMPTY_TRASH_DAYS', 0);
That’s it. The trash button from your WordPress will just elope and your old loving Delete button will come back:).
One more thing, by default WordPress keeps stuffs in trash for 30 days. So if you want to keep the posts in Trash for 3 days, write like:
define('EMPTY_TRASH_DAYS', 3);
