mysql_fetch_array

[Tandem]

Is there anyway to specifiy a certain row number for mysql_fetch_array? Or do i need a different function all together?

I was faced with this dilemna a long time ago... put in an 'id' field in MySQL (assuming you meant you want to only pull a row from MySQL DB)

Call the query
[code]
$query = mysql_query( "SELECT * FROM `table_name` WHERE id = 'some id'" );
[/code]

Let us know if that helps

Thanks for the reply.

Thats not what i meant, i probably should have gone into more detail, sorry about that :P

I'm using a for loop to pull multiple rows from a table and display them in order, via Select * from....etc. But now i need to start the process from a certain row. Is there any way to do that?

Ya, look into LIMIT

SELECT * FROM table
LIMIT (the row, 1)

Ahhhhhhh, yes...  place this after your order by statement in the query...

[code]
LIMIT OFFSET offest_row
[/code]

Sorry, since you are limiting to 1 row, go with what extrovertive said, but be sure to check out MySQL's page for help on that kinda stuff, they are very in depth with it.

I think you are both misunderstanding me. I'm gonna go into way more depth so you can get more of an uderstanding of where i'm coming from. Sorry for not just doing that in the first place.

Ok. A few months ago i made a message board/forum. I'm now currently trying to make it so that the number of topics displayed on a single page is limited.

To display the topics i use (This is very simplified from the real thing):

[code]
$get_topic_details = mysql_query("SELECT * FROM FORUM");
for ($i = 0 ; $i < $number_of_topics ; $i++) {
$topic_details = mysql_fetch_array($get_topic_details);
echo "$topic_details[1]";
}[/code]

This cycles through the rows., and echo's $topic_details[1] which would be the title or something. But now i want to create different pages showing the topics that have fallen below the top 30, showing 30 topics per page. I want to be able to start the mysql_fetch_array at row 30, or or any other number i may need to start it at. How would i go about this. Please say if you need more detail.

it's called pagination.  do a search on that keyword. lots of posts and tutorials here about it.

Ya, paginiation deals with manipulation of LIMIT in mysql.
