paging query problem

[palmerram]

here is my paging code:\[code\]function getPagingQuery($sql, $itemPerPage = 10){ if (isset($_GET['page']) && (int)$_GET['page'] > 0) { $page = (int)$_GET['page']; } else { $page = 1; } // start fetching from this row number $offset = ($page - 1) * $itemPerPage; return $sql . " LIMIT $offset, $itemPerPage";}function getPagingLink($sql, $itemPerPage = 10, $strGet =""){ $result = dbQuery($sql); $pagingLink = ''; $totalResults = dbNumRows($result); $totalPages = ceil($totalResults / $itemPerPage); // how many link pages to show $numLinks = 10; // create the paging links only if we have more than one page of results if ($totalPages > 1) { $self = 'http://' . $_SERVER['HTTP_HOST'] . $_SERVER['PHP_SELF'] ; if (isset($_GET['page']) && (int)$_GET['page'] > 0) { $pageNumber = (int)$_GET['page']; } else { $pageNumber = 1; } // print 'previous' link only if we're not // on page one if ($pageNumber > 1) { $page = $pageNumber - 1; if ($page > 1) { $prev = " <a href=http://stackoverflow.com/"$self?page=$page&$strGet/\">[Prev]</a> "; } else { $prev = " <a href=http://stackoverflow.com/"$self?$strGet\">[Prev]</a> "; } $first = " <a href=http://stackoverflow.com/"$self?$strGet\">[First]</a> "; } else { $prev = ''; // we're on page one, don't show 'previous' link $first = ''; // nor 'first page' link } // print 'next' link only if we're not // on the last page if ($pageNumber < $totalPages) { $page = $pageNumber + 1; $next = " <a href=http://stackoverflow.com/"$self?page=$page&$strGet\">[Next]</a> "; $last = " <a href=http://stackoverflow.com/"$self?page=$totalPages&$strGet\">[Last]</a> "; } else { $next = ''; // we're on the last page, don't show 'next' link $last = ''; // nor 'last page' link } $start = $pageNumber - ($pageNumber % $numLinks) + 1; $end = $start + $numLinks - 1; $end = min($totalPages, $end); $pagingLink = array(); for($page = $start; $page <= $end; $page++) { if ($page == $pageNumber) { $pagingLink[] = " $page "; // no need to create a link to current page } else { if ($page == 1) { $pagingLink[] = " <a href=http://stackoverflow.com/"$self?$strGet\">$page</a> "; } else { $pagingLink[] = " <a href=http://stackoverflow.com/"$self?page=$page&$strGet\">$page</a> "; } } } $pagingLink = implode(' | ', $pagingLink); // return the page navigation link $pagingLink = $first . $prev . $pagingLink . $next . $last; } return $pagingLink;}\[/code\]im calling it like:\[code\]$sql = "something";$result = mysql_query(getPagingQuery($sql, $rowsPerPage)); $pagingLink = getPagingLink($sql, $rowsPerPage, $url);\[/code\]now if my url is like http://xyz/abc/list.php its working fine.but when my url is likehttp://xyz/abc/list.php?action=defafter i click on page 2 the url changes like http://xyz/abc/list.php?page2&'action=def' part is gone so the result changes.if i use to pass the value in $strGet as $_SERVER['QUERY_STRING']the 1st time it is ok like http://xyz/abc/list.php?page2&action=defbut from the 2nd time onwards it gives like http://xyz/abc/list.php?page3&page2&action=defso not getting the desired result.whereas i want it to be like http://xyz/abc/list.php?page3&action=defplz help.. thanxx in advance
