when mysql_insert_db is used without a parameter, as in mysql_insert_db(), it seems to always return 0 instead of the primary key of the most recent insert. It works fine when the db_link is provided as a parameter. Same problem in PHP 4.0.6 running on Linux.

I think you meant mysql_insert_id(), right?
 [2002-05-06 15:49 UTC]
mysql_insert_id() only returns something if:
-the most recent query was an INSERT query
-AND you're using a AUTO_INCREMENT (and thus PRIMARY KEY) field in the table you're inserting data to.
If that's not the case, mysql_insert_id() will return 0.

sorry. I meant mysql_insert_id
 [2002-05-06 16:11 UTC] t dot tremaine at open-for-biz dot com
Several scripts broke on two different servers when a php upgrade was made. The db query is an insert and the mysql_insert_id now requires a parameter to work properly whereas before it did not.

First you said, you have the problem with 4.1.2 (as stated in this report Version: field) and the same problem with 4.0.6 .

So which version did worked for you and from which version did you upgrade to 4.1.2 where it broke?
 [2002-05-06 18:37 UTC] t dot tremaine at open-for-biz dot com
The server running 4.0.6 on linux is my development server . I upgraded that in response to the file upload security issue. The server running 4.1.2 is my production server and they do upgrades on their own timetable. They were previously running a version slighly older than 4.0.6. I have now included the db link as a parameter in all instances of mysql_insert_id and everything is back to working fine.

To further clarify... I'm not sure what version I was running on my development server before 4.0.6. I do know I've been using version 4 for a long while but I do not recall specifically. sorry.

Also see Bug #17343.

We pinned it down and general reasoning for why it's happening as well as a work around.
