Please tell me the select query in blocked user all posts should be hide my query is:

SELECT * FROM `user_block`
  WHERE `id` NOT IN (
    SELECT `post_id` FROM `user_block`
      WHERE `user_id` = '{$userID}'
      AND `status` = '1'
  )

But this query doesnot hide blocked user all posts

Answer 1

This:

select * from user_post
where '{$userID}' not in (
  select user_id from user_block
  where status = '1'
)

will hide all posts if userid has the value 1 inside user_block.
If you want the user to see only his own posts:

select * from user_post
where '{$userID}' not in (
  select user_id from user_block
  where status = '1'
)
and user_id = '{$userID}'
