Question

I am using pagination with my script. But even it has few search cafeterias. And my pagination is also not working because of that search criteria. I want to display all the records 1st and then if the search criteria given it has to display according to that. Then only my pagination works.
But i am not getting how to do
here is my script which is to display records from database with pagination
if(isset($_GET['page'])){ $page=$_GET['page']; } else { $page=1; }
$start_page=($page-1)*5;
`$sql="query";
if(isset($_POST['submit']))
{
$company = $_POST['company'];
$product = $_POST['product'];
if(isset($_POST['submit']) && ($_POST['company']!='') && ($_POST['product']!=''))
{
$sql= "My query goes here";
}
elseif(isset($_POST['submit']) && ($_POST['company']!=''))
{
$sql= "My query goes here";
}
elseif(isset($_POST['submit']) && ($_POST['product']!=''))
{
$sql= "My query goes here";
}
elseif(isset($_POST['submit']))
{
$sql= "My query goes here";
}
}
$sql1 = mysql_query($sql) or die(mysql_error());
//Display
?>
<div class="w-box w-box-blue">
<div class="w-box-header">
</div>
<div class="w-box-content">
<table id="dt_hScroll" class="table table-striped">
<thead><tr>
<th>Order ID</th>
<th>Company</th>
<th>Reference</th>
<th>Total Value</th>
<th>Action</th>
</tr>
</thead>
<?php
while($row=mysql_fetch_array($sql1))
{
//Display
}
?>
</table>
</div>
</div>
<?php
//PAGINATION SCRIPT
$sql1="select COUNT(order_id) from orders";
$rs_result = mysql_query($sql1);
$row1 = mysql_fetch_row($rs_result);
$total_records = $row1[0];
$total_pages = ceil($total_records / 5);
if ($page > $total_pages) {
// set current page to last page
$page = $total_pages;
} // end if
// if current page is less than first page...
if ($page < 1) {
// set current page to first page
$page = 1;
} // end if
$range=4;
echo "<div style='float:left; width:200px;text-align:center; margin-left:40%;'>";
// echo "<a href='view_student.php?page=".$i."'>".$i."</a> ";
if ($page > 1) {
// show << link to go back to page 1
echo " <a href='{$_SERVER['PHP_SELF']}?page=1'>First</a> ";
// get previous page num
$prevpage = $page - 1;
// show < link to go back to 1 page
echo " <a href='{$_SERVER['PHP_SELF']}?page=$prevpage'>Previous</a> ";
} // end if
// loop to show links to range of pages around current page
for ($x = ($page - $range); $x < (($page + $range) + 1); $x++) {
// if it's a valid page number...
if (($x > 0) && ($x <= $total_pages)) {
// if we're on current page...
if ($x == $page) {
// 'highlight' it but don't make a link
echo " [<b>$x</b>] ";
// if not current page...
} else {
// make it a link
echo " <a href='{$_SERVER['PHP_SELF']}?page=$x'>$x</a> ";
} // end else
} // end if
} // end for
// if not on last page, show forward and last page links
if ($page != $total_pages) {
// get next page
$nextpage = $page + 1;
// echo forward link for next page
echo " <a href='{$_SERVER['PHP_SELF']}?page=$nextpage'>Next</a> ";
// echo forward link for lastpage
echo " <a href='{$_SERVER['PHP_SELF']}?page=$total_pages'>Last</a> ";
} // end if
echo "</div>";

Try using some kind of query builder, that would make your task easier.
All popular frameworks have that kind of tool. It would be much easier to build count query for pagination.
You may look here for example http://framework.zend.com/manual/1.12/en/zend.db.select.html
