Next Page/Previous Page..

[KrisCons]

Hi,

I have a form which retrieves specific products from a database, but i need to have 'Next Product' and 'Previous Product' links at the bottom of the page to help navigate forward and backwards.
My code basically states If $prodid = 0; open a form ready to create a new product. But i need my 2nd form to have the navigation buttons on so im guessing it might be something along the lines of

<a href="next$prodid">click here for next Product</a>

As you can probably see, Im a novice at PHP so any advice would be GREATLY appreciated..

Thankyou in advance.

I use this (probably quite badly coded, but hey, i was in a rush!!) code to do a photograph display thing that is quite similar to what you want.

<?php
     $current_dir = "photos";
     $dir = opendir($current_dir);
     $number_of_photos = 0;
     while($file=readdir($dir))
     {
         $number_of_photos++;
     }
     $number_of_photos -= 2;
     echo "<p>";
     if((int)$photo>10)
     {
         (int)$previous_photo=((int)$photo-1);
         echo "<a href=\"display_photo.php?photo=".(int)$previous_photo.".jpg\">Previous Photo</a> | ";
         if((int)$photo==($number_of_photos-1))
             echo "<a href=\"display_photo.php?photo=00.jpg\">Next Photo</a>";
         else
         {
             $next_photo=($photo+1);
             echo "<a href=\"display_photo.php?photo=".(int)$next_photo.".jpg\">Next Photo</a>";
         }
     }
     else
     {
         (int)$previous_photo=((int)$photo-1);
         if((int)$previous_photo>=0)
             echo "<a href=\"display_photo.php?photo=0".(int)$previous_photo.".jpg\">Previous Photo</a> | ";
         else
             echo "<a href=\"display_photo.php?photo=".(int)($number_of_photos-1).".jpg\">Previous Photo</a> | ";
         if((int)$photo==($number_of_photos-1))
             $next_photo=00;
         else
             $next_photo=($photo+1);
         if((int)$photo>8)
             echo "<a href=\"display_photo.php?photo=".(int)$next_photo.".jpg\">Next Photo</a>";
         else
             echo "<a href=\"display_photo.php?photo=0".(int)$next_photo.".jpg\">Next Photo</a>";

 }
?>

There's nothing too complicated in there - just have a look through and see if you can get what's gonig on and the tinker with it to do what you want yours to do.
