Comment (by jigar bhanushali):

 I have added an improved version of the previous patch. I hope this works
 well.

 - Fixed missing sanitization in other areas.
 - Eliminated redundant isset checks for the same variable.
 - Removed unnecessary variable casting for $post_category as it is already
 handled in the condition.
