Hi All-
I was wondering what the best way to create previous and next buttons
when pulling products from a database? I haven't had much luck so far
and was wondering if someone had an easy / efficient way to accomplish
this?
Thx-
M

I once used the script below on a dbase database.

<script language="PHP">

$file_name='dbs/files.DBF';
$ret=dbase_open($file_name,0);
$max=dbase_numrecords($ret);
if (isset($start))
{
$start_record=$start;
}
$arr = dbase_get_record_with_names($ret,$i);
echo($file_name);
</script>

Sorry I can't be much more help than this... but lookup the LIMIT
function for MySQL. If you track how many records your displaying on
each page, and what record your on, it's pretty straight forward to make
next, prev page navigation. Next and prev will obviously have pointers
to whatever record your currently on, and it should be fairly straight
forward...
Hope this helps anyway...

I have read a little about PHP classes, my question is what good are
they really? What are some examples that I can use these to my
advantage? Are there any really good tutorials about these aside from
the PHP.net site?
Thx~!

Matt,
Object Oriented Programming (OOP) is good because it promotes code reuse
and code encapsulation. Well, PHP4 doesn't do a good job of this. I love
OOP, but I'm waiting for PHP5 to do any OO with PHP. Stick to procedural
PHP for now, and you'll be just fine.

you guys should really search the archives for answers, this is a very
common problem:
http://marc.theaimsgroup.com/?l=php-windows&w=2&r=1&s=headers+already+sent&q=b
Here's the thing... the session stuff is done with HTTP cookies. Some
people do it with session vars in every URL, but most of the time its
cookies.
Anyway, HTTP cookies have to be sent in the HTTP headers of the request,
along with content type, content length, etc. After you send them, you
can start sending HTML text.
If you try to set session vars or cookies in the middle of a PHP page,
it will fail, because the HTTP headers are already set. You can only do
session and header manipulation at the ABSOLUTE TOP of your PHP page.
No white space whatsoever.
You can get around this limitation by setting 'output_buffering' to some
number in your 'php.ini' file... most likely your dev box has this set,
but your ISP does not.

I had the same message the other day. My line 5 is where I call a
function. I had a </table> tag as the very last line of a function but
had it outside the closing brace } so I moved </table> inside the
closing brace } and the problem went away.

What does this mean:
Warning: Cannot send session cookie - headers already sent by (output
started at
/customers/pingstkyrkan.net/pingstkyrkan.net/httpd.www/fp/index.php:1)
in
customers/pingstkyrkan.net/pingstkyrkan.net/httpd.www/fp/index.php on
line 5
Warning: Cannot send session cache limiter - headers already sent

line
5
The php-file worked perfectly well on my local machine...

Has anyone here successfully sent CC headers with mail()? It simply
won't work for me. I get different errors depending on which mail server
I use.

Both
