[PHP-DB] multiple queries in the same request
I have a table with some relational values, that really saves me on selects, but gives me a weird error in the insert... in the DB i have this 2 tables data and categories: data( id int category tinyint ), categories ( id tinyint description varchar ) for selects i can use a single query with a left join. but to populate the table without having to use magic numbers in my code i've come up with: SELECT (@category_id:=id) FROM categories WHERE description = cat1; REPLACE INTO data VALUES( 10, @category_id); i send this as a single query in PHP and it returns an error quoting everything after the first ; anyidea if i can't send several queries at once? any workaround?

You can't send multiple queries in an SQL statement. You can just split that in two separates queries.

[PHP-DB] auto-generating next id (in order) for an add script
Hello, I have a site that allows reporters to enter their articles into a forum. I am then spilling their articles onto the main page from a MySQL dbase via a php script, read LATEST ARTICLES. I am now entering the data myself after they email it to me, however this is becoming more of a task I dont' have time for as the number of articles increase per day. Right now, I have an addarticle.php page where they can enter their information. I have ran a test of this script, and it works great. However, I have been entering the PHP IDs myself in ascending order (i.e. 0005, 0006, 0007) because I can see all of the articles. The reporters however are not able to see these articles, and instead of having them enter a random php ID, I'd like my add script to check for the last ID entered and then enter the number above (i.e add row to table, check PHP ID, if 0007 is last row entered, enter 0008 for php ID for new article).

Re: [PHP-DB] auto-generating next id (in order) for an add script
Use an autonumber field in MySQL. It will increment automatically every time you insert a record, and not repeat numbers. No extra PHP code needed. After the insert query, you can then issue a mysql_insert_id() function that will return the autonumber field for the last insert, that way you can know what it was (if you need that) Don't do it with PHP. -Micah On Monday 20 June 2005 09:54 am, [EMAIL PROTECTED] wrote: Hello, I have a site that allows reporters to enter their articles into a forum.

[PHP-DB] Threading theory help needed
Hi there everyone, I've written a simple forum in PHP for my website (It's an artistic Jean-Michel Jarre website called Planet Oxygene where I experiment with all things tech) but I want to add threading to my messages but I'm not sure of the theory for such a thing. For example, I know I need ID, messageid, forumid and messagerootid (Just example names) but I'm not sure of the theory of how replies to replies etc ... would work in PHP with MySQL? I guess I'm just confused on the whole threading business and I'm just looking for some good explanation of how I can easily add threading to my messageboard (Assuming my messageboard is just an average system which adds the ID as an auto-numerator, the messageid and all subject etc ...). Any help would really be appreciated just on the basics of how threading works so I can work out the code. Thank you for your help on this, a very confusing subject for me :-) Chris

What I usually do in the interest of just keeping things simple, is to just have a message ID, and parentID. You can then calculate the root message (select * from messages where parentID = 0) and get children from there (select * from messages where parentID = $messageID) Anytime a reply is made, just make the original messageID the parentID of the reply. This makes unlimited threads which leads to some formatting issues (if you're indenting for each reply, for example, you must limit the indenting at some point) but that's a seperate issue.
