Pagination

[sandy1028]

if (isset($_GET['currentpage']) && is_numeric($_GET['currentpage'])) {
   // cast var as int
   $currentpage = (int) $_GET['currentpage'];
} else {
   $currentpage = 1;
} // end if

// if current page is greater than total pages...
if ($currentpage > $totalpages) {
   // set current page to last page
   $currentpage = $totalpages;
} // end if
// if current page is less than first page...
if ($currentpage < 1) {
   // set current page to first page
   $currentpage = 1;
} // end if

// the offset of the list, based on current page
$offset = ($currentpage - 1) * $rowsperpage;
if ($currentpage > 1) {
   // show << link to go back to page 1
   echo " <a href='{$_SERVER['PHP_SELF']}?currentpage=1'>First</a> ";
   // get previous page num
   $prevpage = $currentpage - 1;
   // show < link to go back to 1 page
   echo " <a href='{$_SERVER['PHP_SELF']}?currentpage=$prevpage'>Previous</a> ";
} // end if

   echo " <a href='{$_SERVER['PHP_SELF']}?currentpage=$x'>$x</a> ";

// if not on last page, show forward and last page links
if ($currentpage != $totalpages) {
   // get next page
   $nextpage = $currentpage + 1;
   echo " <a href='{$_SERVER['PHP_SELF']}?currentpage=$nextpage'>Next</a> ";
   echo " <a href='{$_SERVER['PHP_SELF']}?currentpage=$totalpages'>Last</a> ";
} 

Here when I am in first page I should also display First and Previous with no links and When in last page also I have dispaly Next and Last with no links.

How to do it

Could I ask you to please use php bb tags, instead of code?

anyway, and easy addon to your code;

if ($currentpage > 1) {
   // show << link to go back to page 1
   echo " <a href='{$_SERVER['PHP_SELF']}?currentpage=1'>First</a> ";
   // get previous page num
   $prevpage = $currentpage - 1;
   // show < link to go back to 1 page
   echo " <a href='{$_SERVER['PHP_SELF']}?currentpage=$prevpage'>Previous</a> ";
} // end if
else
 {
   echo " Previous ";
 }
   echo " <a href='{$_SERVER['PHP_SELF']}?currentpage=$x'>$x</a> ";

// if not on last page, show forward and last page links
if ($currentpage != $totalpages) {
   // get next page
   $nextpage = $currentpage + 1;
   echo " <a href='{$_SERVER['PHP_SELF']}?currentpage=$nextpage'>Next</a> ";
   echo " <a href='{$_SERVER['PHP_SELF']}?currentpage=$totalpages'>Last</a> ";
}
else
{ 
echo "next";
}
