Pagination script not working

[ROXIT]

Here i am collecting the category and area value from the search-form using get method. So as i m having 7 records into the database and i want to display only 4 records per page and when user clicks on Next button then the remaining records need to get displayed but here my code is displaying only first four records from the database but when i click on next button then the remaining 3 records are not getting displayed.

Consider area=Mumbai and category=lawn. and if there is only 7 records into the database then i want first four to get display in first page and remaining 3 into the same page on clicking the next button..

Here is my code:

<?php
    $link=mysql_connect("localhost","root","");
    mysql_select_db("celebration_db",$link);
    $q="select count(*) \"total\"  from hallinfo";
    $ros=mysql_query($q,$link);
    $row=(mysql_fetch_array($ros));
    $total=$row['total'];
    $dis=4;
    $total_page=ceil($total/$dis);
    $page_cur=(isset($_GET['page']))?$_GET['page']:1;
    $k=($page_cur-1)*$dis;
 
    $category = $_GET['category'];
    $area = $_GET['area'];
    //$category = 'hall';
    //$area = 'nagpur';
 
    echo $category;
    echo $area;
 
    $q="select * from hallinfo where category = '$category' AND area = '$area' limit $k,$dis";
    //$q="select * from hallinfo limit $k,$dis";
 
    $ros=mysql_query($q,$link);
    while($row=mysql_fetch_array($ros))
    {
        $imageId = $row['id'];
echo '<div id="pattern">';    
echo '<table>';
echo '<tr>';
echo '<td colspan="2" width="300px" height="200px">
        <img src="image-show.php?id='.$imageId.'">';
echo '</td>';
echo '<td width="150px" height="200px">'.$row['description'];
echo '</td>';
echo '</tr>';
echo '<tr>';
echo '<td>'.$row['rent'];
echo '</td>';
echo '<td>'.$row['capacity'];
echo '</td>';
echo '<td>'.$row['area'];
echo '</td>';
echo '</tr>';
echo '</table>';
echo '</div>';
    }
    //echo '</table>';
    //echo '<br/>';
    if($page_cur>1)
    {
        echo '<a href="pagination.php?page='.($page_cur-1).'" style="cursor:pointer;color:green;" ><input style="cursor:pointer;background-color:green;border:1px black solid;border-radius:5px;width:120px;height:30px;color:white;font-size:15px;font-weight:bold;" type="button" value=" Previous "></a>';
    }
    else

    }
    for($i=1;$i<$total_page;$i++)
    {
        if($page_cur==$i)
        {
            echo ' <input style="background-color:green;border:2px black solid;border-radius:5px;width:30px;height:30px;color:black;font-size:15px;font-weight:bold;" type="button" value="'.$i.'"> ';
        }
        else
