ok this is simple. well sounds simple.. but I just want it to be 100% correct from the start.

I have 6 photo PAGES.

6 photos on 6 single pages.

I have PREVIOUS and NEXT buttons at the bottom.

ive tried my own attempt at this and I get blank screen.

So..

what im trying to do is make page 1.. if I hit next..
it goes to page 2.. ( simple enough current page+2) But!
on page one if I hit previous ..I want it to add 5 to make it 6 and go to page 6.

lol now im confusing myself.

heres what i tried..

IF ($pg_num>6) {
$pg= (1)};

and
If ($pg_num<1){
$pv=(6)};

so more or less if your on page 1 and hit previous.. it "should" take you to page 6

and if your on page 6 and hit next.. it "should" take you back to page 1

wheres my error? or does anyone have a simpler easier method for me.

thanks.

--- Well edited this one before anyone answered..

can someone check this for me and tell me if its safe to use and logical..
It works fine for what im looking for just need some input.

thanks.

IF ($Pg_Num >= 6) {
$pg= '1';
} else {
$pg = $Pg_Num + 1;
}

IF ($Pg_Num <= 1) {
$pv= '6';
} else {
$pv = $Pg_Num - 1;
}

lemme know if thats safe and logical.

Try this sample code -

PHP Code:

<?php

// pages are numbered 1 through max_page

$max_page = 6;



for ($cur_page = 1; $cur_page <= $max_page; $cur_page++) {



$next_page = $cur_page + 1;

if ($next_page > $max_page) {

    $next_page = 1;

}

$prev_page = $cur_page - 1;

if ($prev_page < 1) {

    $prev_page = $max_page;

}

echo "Prev: $prev_page, Current: $cur_page, Next: $next_page<br>";

}

?>

Basically, the next page is always one more than the current page. When it becomes greater than the maximum (6 in your case) wrap this around to the starting page. Going the other direction, the previous page is always one less than the current page. When it becomes less than the starting page (1) wrap this around to the maximum page.

thanks! is this safe tho?? its already in my script.

IF ($Pg_Num >= 6) {
$pg= '1';
} else {
$pg = $Pg_Num + 1;
}

IF ($Pg_Num <= 1) {
$pv= '6';
} else {
$pv = $Pg_Num - 1;
}

lemme know.

Yes that appears to be correct code.

Although the script MAB posted is more efficient
