Gents,
I want to be able to provide my users with a simple search box which allows them to type in and it goes off and searches the main fields of the table and displays the results.
Here is what I have so far.
As you can see, here I am searching by username. I just wanted to check it worked, and it does.
so firstly, I want to be able to search all fields, not just surname. Can I add to it like this?
??
Or do I have to make a query for each one?
Secondly, when the results are displayed, I'd like to make the results a clickable link to show the full result (all fields). Is that possible?
I have set it up so that results are limited to 10 and then spread across pages with next/back links although i'm not sure I'll ever need that.

}
// calculate number of pages needing links
$pages=intval($numrows/$limit);
// $pages now contains int of pages needed unless there is a remainder from division
if ($numrows%$limit) {
// has remainder so add one page
$pages++;
}
// check to see if last page
if (!((($s+$limit)/$limit)==$pages) && $pages!=1) {
// last page so give NEXT link
$news=$s+$limit;

I'll add the escape strings when I've got the frickin thing working
