Question

am using search items to filter the city,gender,profession and state. it should display 3 rows per page. but it display the first page. when i presss the last page, again it comes back to home page.

<?php
if(isset($_POST['submit']))
{                           
    $con = mysql_connect("localhost","root","");

    if (!$con)
    {
        die('Could not connect: ' . mysql_error());
    }

    mysql_select_db("nursingcarein",$con);

    if (isset($_GET["page"])) {
        $page  = $_GET["page"]; 
    } else { 
        $page=1; 
    };

    $start_from = ($page-1) * 3;
    /*pass the values(city,gender,profession,state) frm search */

    $city=$_POST['city'];

    $gender=$_POST['gender'];

    $profession=$_POST['profession'];

    $state=$_POST['state'];

I'm not sure if this is your problem but the following code :

LIMIT $start_from, 3

Does not work if $start_from is greater than 3. If you want 3 records, you have to do this :

$end = $start_from + 3;
// Your code here
LIMIT $start_from, $end
