Tiny Code snip - Big headache

Anon

I have been fighting with this for a few hours...

I am simply trying to NOT have previous show up on the first page of the results ... I am sure the problem is in the IF STATEMENT... HELP.

// check to see if first page
if (!(($offset/$limit)==$pages))

{
// not first page do Previous link

$prevoffset=$offset-10;
print "<a href=\"$PHP_SELF?offset=$prevoffset\">Previous</a>\n";

}

there is an article on phpbuilder about this exact thing.

I think it's titled "building next / previous buttons"

take a look at it

Try this:

// check to see if first page
$prevoffset=$offset-10;
if ($prevoffset>0)
{
// not first page do Previous link
print "<a
href=\"$PHP_SELF?offset=$prevoffset\">Previous</a>\n";
}

Hiya Fritz! Long time no see. I've been too busy with my own site to visit yours for a long time.

I found this bit of code that helped me with the exact same thing. Very similar to what you've got there, but I use a variable for my limit, as users can choose how many results per page.

// If page 1, then don't show PREV
if ($offset >= 1) {
$prevoffset = $offset - $limit;

echo "<a href=\"$PHP_SELF?query=$holdquery&offset=$prevoffset&limit=$limit&numrows=$numrows\"> 	[PREV]</a>&nbsp;\n"; 
} 

// calculate number of pages needing links
$pages=intval($numrows/$limit);

Hope this helps and is not redundant to what's already been covered.
Cheers!
