Hi,
I've never used a lock on a MySQL table so far, but need one now. Two
questions:
1. Do I set the lock by a normal query, but in the form of LOCK TABLE
tablename WRITE, instead of SELECT * FROM tablename WHERE x = 1?
2. Can I set the lock in one query, then perform multiple other queries
Doing what I wanted to do took six hours and 120 lines of code, all in
all, but I learnt a good deal on the way. ;-)
At times, manual intervention can be a lifesaver.
You have already said that you have to 'ring fence' bank
holidays, and weekends, so someone has to check or enter the
bank

What I would like to do is somehow have a redundant error
check on the server
side and then display an error message above the form on the
main page should
fields be left blank or

If you're trying to do paging, it's quite simple (there are tons of examples
out there, search google for paging php)
$sql = select count(*) from table_name
$number_of_records = mysql_query($sql);
$pointer=0;
$recs_per_page=20;
if($number_of_records $recs_per_page) {

Gary, thanks for your reply, I think I'll need 2 have a think about this. I
didn't totally understand:
You limit
the query by LIMIT starting_point,number_of_records_to_return at the end
of the sql statement.
I've never used LIMIT before, could you explain this a bit more or point me
to some
Graeme,
Use a select string as in,
$sel=select * from product where price100 order by price LIMIT 0,100;
This would result in the query only returning the first 100 records. If you
want to page through them (back and next links). You would have to save the
current start point and the length
LIMIT 0,10 will return the first ten records of a result set. To make more
sense, you should do an ORDER BY of some field to get the info sorted
correctly.
LIMIT takes 1 or two arguments
If there is only one argument, say 10, it will return the first ten records.
If there are two arguments, LIMIT
Michael, thank you so much for that code. I think I could maybe get this
working properly. I've got 2 categories and 4 products in each and I want
to split them in to 2 pages, 2 products on each. So obviously I will have 2
links at the bottom page 1 2.. etc when I click the link 2 I will

I suggest in my last post. If not please let me know.
Thank you both Gary and Michael!
Cheers,

I am compiling latest PHP4 and get a warning telling me that I am about
to compile without redirection checking. Should I be concerned about
this? If so, what flag should I use in the config to alleviate this?

Peter and Hugh,
The queries are already mostly optimized. I just was using that one as an
example. I'll be going through them and tweaking them, but know that about
the variable assignments helps for sure.
Thanks!
