------ Solution --------------------
When a post is locked, a field can be added to indicate the status of the post. for example, if 0 is set to "reply 1", the field cannot be set to "reply 1 ".
The top field is also the final SQL statement of a field. order by ** adds this field to sort.
For batch uploads, you can use google php flash for batch uploads.
