Hello!!
CREATE TABLE `hold_tracker` ( `id` int(11) NOT NULL auto_increment, `STUDENT_ID` int(11) NOT NULL default '0', `USER_ID` int(11) NOT NULL default '0', `valid` char(1) NOT NULL default '1', `date_held` bigint(20) NOT NULL default '0', `date_created` bigint(20) NOT NULL default '0', PRIMARY KEY (`id`) ) TYPE=MyISAM AUTO_INCREMENT=12 ;
This works okay, for just keep track of who is holding the student. There are some restrictions:
1. A Coordinator may only hold 3 students at a time. (PHP logic, this is done already.) 2. A Coordinator can only hold a student while in the #1 position for a certain amount of time. (I don't have a problem with calculating the time.The problems are: A. What do I do with the record once there hold has expired?
Who checks for this???
If it's user based, then that's easy...Have a user run some type of report, or something like that
But if you/they want this automatic, then it's a little more involved...
What I've done in the past..Running Linux of course...
Create a mysql query text file and save it..(example)
SELECT STUDENT_ID FROM hold_tracker WHERE USER_ID = 'blah'
Create a bash script...(Example)
#!/bin/sh
#
#
#
mysql database_name -uJoe -pblow <query | mail whatever@xxxxxxxxxxxx -s "Student Name Has Expired"
Then use CRON to start the Bash script at a certain time...
