RE: [PHP-DB] advise needed for 'authorized only' site
I do pretty much the same thing but with seesion vars, I just check that the user and level session vars are the appropriate values before I display confidential material. -Steve. -Original Message- From: Rob Day [mailto:[EMAIL PROTECTED]] Sent: Monday, September 23, 2002 11:22 AM To: 'PHP DB' Subject: RE: [PHP-DB] advise needed for 'authorized only' site I had a similar problem, but I can't promise that my solution is the best way to go about it. After the user was validated, I set a cookie. I then had all subsequent pages start with an if statement that checked for the cookie. If there was no cookie, they were sent back to the entry point.

I am currently using mysql authorization, which works for the first page, but if someone were to type in the url of an underlying page they would be able to get in without authorization. I know I could use .htaccess for handling this but with a minimum of 350 -400 users to keep track of that would be unwieldly to say the least, especially for my boss who doesn't have a clue about *nix and has never even heard of .htaccess.

RE: [PHP-DB] time field query problems.
Thanks, I wasn't sure what kind of field to use, I'll give the timestamp a try and set 0 as default.

Steve, For some reason the below statement is not working. Can anyone tell me why? Select EDIT_LOCK from ordmaster where EDIT_LOCK + INTERVAL 10 MINUTE now() AND ORDER_NO = '5' AND EDIT_LOCK 0; -EDIT_LOCK is a MySQL (ver 3.23.49-max) time field, allows nulls, default is NULL. If this cannot be done in a query, whats the best way to compare time in php? The best way to compare time in PHP is to use the MySQL RDBMS that is managing/retrieving the data for you. Recommendation 1: do not use a Time field (you did mean the back 'half' of a Date-time field didn't you?). Because you are (apparently only) using this field to temporarily lock a row, the value is only ever used for computation (cf display). A Timestamp field is best for computation - a Time field for presentation. Consider also storing such data as an integer field or beware the automatic update feature for Timestamp fields. Recommendation 2: re-consider the (default) use of NULL - this may be the root of the question you're asking: what if the row has never been 'locked' and attempt the (above) SELECT? (then the last comparison clause would be illogical) If the default were zero (0 or 00:00:00) and the retrieval logic updated slightly, things should be less complicated.

RE: [PHP-DB] time field query problems.
Ya I checked and the manual said that with a version 3.23 or higher you can use + and - signs instead of the date_add subtract. Either way it just returns null. Ever tried somthing like this?

you have to do something like this:

mysql_query('COMMIT'); or mysql_query('ROLLBACK');

use InnoDB, because InnoDB supports row-level locking, and InnoDB also

[PHP-DB] indexing
Hi all, More of a database question here, my apologies: I've been doing some reading on indexes but I thought I should get an experienced persons input. My question is about Over Indexing. I have a MySQL MyISAM table that stores inventory transactions, in, out etc. I store numeric fields that are primary indexes in other tables, 2 datetime fields and a qty field, Paul DuBois' MySQL book says that anything used in a where clause or join clause is a candidate for an index. It turns out that 7 out of eight fields fit this description,1 primary key, 4 smallints, and 2 are datetime fields. Should I use all these indexes or is this overkill?
