Pagination and search results

[ragrim]

I have a page setup that paginates 20 results per page and works fine when i do SELECT * or what ever, but when i do a search query it displays fine on page 1, but when i go to page 2 or any other page it displays all results. Im assuming to use pagination i have to load my query into an array or something instead or using a while loop. Im not great with php so any help here would be appreciated.

 

heres my code, i have a search page thats posts to my search results page.

 

 

<?php

include('include/dbconnect.php');

$fname = $_POST['fname'];
$lname = $_POST['lname'];
$address = $_POST['address'];
$suburb = $_POST['suburb'];

// find out how many rows are in the table 
$sql = "SELECT subscribernumbers.SubNumber,
userinfo.FirstName,
userinfo.LastName,
userinfo.Suburb,
userinfo.Phone,
userinfo.Mobile,
userinfo.Email,
userinfo.BusinessName
FROM
userinfo
LEFT JOIN subscribernumbers ON userinfo.User_ID = subscribernumbers.FKUserID WHERE FirstName LIKE '%$fname%' AND LastName LIKE '%$lname%' AND Suburb LIKE '%$suburb%'";
$result = mysql_query($sql) or trigger_error("SQL", E_USER_ERROR);
$r = mysql_fetch_row($result);
$numrows = mysql_num_rows($result);

//echo $sql;

echo "<p class='messagetext'>Query returned " . $numrows . " results</p>";

// number of rows to show per page
$rowsperpage = 20;
// find out total pages
$totalpages = ceil($numrows / $rowsperpage);

// get the current page or set a default
if (isset($_GET['currentpage']) && is_numeric($_GET['currentpage'])) {
   // cast var as int
   $currentpage = (int) $_GET['currentpage'];
} else {
   // default page num
   $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;


$result = mysql_query("SELECT 
subscribernumbers.SubNumber,
userinfo.User_ID,
userinfo.FirstName,
userinfo.LastName,
userinfo.Phone,

i think i just realised my problem, because the search is coming from a seperate page, when it goes to page 2 its not getting the search terms, should i be passing it with a GET instead of post?
