Any one got any ideas?

cooldude832 · October 29, 2007

check if you sql is erroring I didn't see any error reporting on it.

iceblox · October 29, 2007

Yeah its not erroring at all i think its having trouble getting the number of rows but im not sure how

cooldude832 · October 29, 2007

replace every $result = mysql_query($query); with

$result = mysql_query($query) or die(mysql_error());

using the right variable names in place and check what happens.

iceblox · October 29, 2007

Yeah nothing but i have noticed when i add say &page=11 the prev button works and the results change but the next button doesnt work...

iceblox · October 29, 2007

When i print $totalrows i get 1 and when i print i get $result_count Resource id #6

So its deviding it by one which is probably why the next isnt working as it thinks there arent any more rows but im not sure how to fix it

sasa · October 29, 2007

change:

$totalrows = mysql_num_rows($result_count); to $totalrows = mysql_result($result_count,0,0);

$pageprev = $page--; to $pageprev = $page-1;

$pagenext = $page+1; to $pagenext = $page+1;
