Plugin Fixes: Category Replace, Add and Remove

First of all what a great plugin.

We did however notice some issues right away – none of the Category expiry methods were working even though the Debug Log was indicating that it was successful.

We went ahead and had a look at the code in post-expirator.php and are happy to report that we were able to correct the bugs.

Those of you having similar problems with the plugin can use the following 3 line replacements to correct issues with the category expiration methods:

1) Replace Line 691:
if (wp_update_post(array('ID' => $id, 'post_category' => $category)) == 0) {

with:
if (wp_set_post_categories($id, $category, false) == false) {

2) Replace Line 722:
if (wp_update_post(array('ID' => $id, 'post_category' => $merged)) == 0) {

with:
if (wp_set_post_categories($id, $merged, true) == false) {

3) Replace Line 758:
if (wp_update_post(array('ID' => $id, 'post_category' => $merged)) == 0) {

with:
if (wp_set_post_categories($id, $merged, false) == false) {

What we’re doing here is using the wp_set_post_categories function to apply the categories, rather than the wp_update_post function used in the plugin, then checking whether it returns false rather than 0 after execution in the case of failure.

We hope this helps some of you who may be experiencing similar issues.
