Jeff, When you want to increment an autoincrement field, you just put NULL into the query. For example: INSERT (NULL,'Jeff','php list','Modify MySQL Record') INTO mail; Where NULL is in the same spot in the field list as your autoincrement field. That concept is covered in the MySQL manual. Pretty simple stuff. If you're in a situation where you have an autoincrement field that you sometimes autoincrement and sometimes manually assign a value to, I think you're misusing the autoincrement field (IMHO). If you have that situation, use the autoincrement field to assign a unique ID to the table row and use a separate field with another name for the manually assigned data. As far as the stuff you mentioned about clicking things and getting the messages you expected, I'm kinda' lost. But if you use the autoincrement field as it is intended, the logic should present itself. > -----Original Message----- > From: Jeff [mailto:jroth1@telus.net] > Sent: Friday, September 05, 2003 2:07 PM > To: php-db@lists.php.net > Subject: Re: Modify MySQL Record > > > Ok, so it sorta works now *grin* > > Two new problems > > I added an auto increment field in my table and changed the > php to reflect > that field - But for some reason, it doesn't work.. > When I submit a new record, do I need to tell SQL to add one to the > greatest, or should it do it automatically when a new record > is created? > gradient MEDIUMINT(10) DEFAULT '0' NOT NULL AUTO_INCREMENT, > and I made it the primary. > > Problem two, > > If I manually enter a number into that field, I can make > changes to the > record no problem! but... it goes into some kind of > continuous loop.
