codeigniter

问题 I am using Codeigniter MVC framework, I am trying to insert 14 rows into DB. Also, I have 14 calls for the model in my controller. However somehow, it inserts only Sunday morning.

The form action calls on a function called remove. <form action=

问题 Alright... at 2am, this is where I draw the line. Help... before my laptop ends up going out the window. :) I've tried using setTimer, callbacks, and everything else I can think of (along with a few other Stackoverflow hints of course). I've stripped out everything so I'm leaving just the base code.
