Trouble with paginating a page called by a form

[eluser]Corbee[/eluser]
Hi,

I have a page(a) that calls another page(b) to display the data, the problem is that the data submitted by page(a) to page(b) can't be read by the paginated form. I tried to session the posted data, but it wasn't helpful at all.

Here is the code.
Controller

Code:

class Manage extends controller
{
        function index()
    {
        $data['title']='System Manager';
        $data['main'] = 'admin_manage_home';
        $data['carbrand']= $this->MManage->getcarbrand();
        $data['year']= $this->MManage->getcaryear();
        $this->load->view('dashboard',$data);
    }

    function vehicle()
    {
        $this->load->library('pagination');
        $data['title']    ='Vehicle Management';
        $data['main'] = 'admin_manage_cars';
    
        $config['base_url'] = base_url().'index.php/manage/vehicle';
            $config['total_rows'] = $this->db->count_all('carmodel');
                $config['per_page'] = '15';
            $config['full_tag_open'] = '<p>';
            $config['full_tag_close'] = '</p>';
        
        $this->pagination->initialize($config);

        //load the model and get results
        $data['vehicle'] = $this->MManage->getvehicle($config['per_page'],$this->uri->segment(3));
        
        $this->load->view('dashboard',$data);
    }
}

Model:

Code:

class MManage extends Model
{
    function __construct()
    {
        parent::Model();
    }    
    
    function getvehicle($num='',$offset='')
    {
        $_SESSION['year'] =$_POST['year'];
        $_SESSION['brand'] = $_POST['brand'];
        $year= $_SESSION['year'];
        $brandID = $_SESSION['brand'];
        $data = array();
        //$this->db->select('modelName,carbrand.brandName,carbrand.logo');
        $this->db->from('carModel');
        $this->db->join('caryear','caryear.modelID=carmodel.modelID','left');
        $this->db->join('carbrand','caryear.brandID=carbrand.brandID','left');
        $this->db->where('year',$year);
        $this->db->limit($num,$offset);
        $q = $this->db->get();    
        if ($q->num_rows() > 0)
        {
            foreach ($q->result_array() as $row)
            {
            $data[] = $row;
            }
        }
    $q-> free_result();
    return $data;
    }
    
    function getcarbrand()
    {
        $this->db->distinct();
        $this->db->from('carmodel');
        $this->db->join('carbrand','carbrand.brandID=carmodel.brandID','left');
        $this->db->where('carbrand.brandID IS NOT NULL');
        return $this->db->get();
    }
    
    function getcaryear()
    {
        return $this->db->get('caryear');
    }
    
}

Views:
page(a) - admin_manage_home

Code:

<form action="manage/vehicle" method="post">
<fieldset>
  <legend>Administer Vehicle</legend>
  <p>
<div class="tab1">
    <label for="year">Year:</label>
    &lt;?php //populating the year
    if ($year->num_rows() > 0)
        foreach($year->result_array() as $rows)
        {
            $options[$rows['year']]=$rows['year'];
        }
        
    echo form_dropdown('year',$options);
    ?&gt;
    
  <label for="brand">Brand:</label>
    &lt;?php //populating the brand

    if ($carbrand->num_rows() > 0)
        foreach($carbrand->result_array() as $rows)
        {
            $options1[$rows['brandID']]=$rows['brandName'];
        }
        
    echo form_dropdown('brand',$options1);
    ?&gt;  
    </p>

<div class="tab"><div class="tab"><p>&lt;?php echo anchor('manage/addvehicle','Add a New Vehicle'); ?&gt; or &lt;input type="submit" value="Go"/&gt;&lt;/p></div></div></div>
</fieldset>
&lt;/form&gt;

page(b) - admin_manage_cars

Code:

<?php
echo '<p>';
if ($this->session->flashdata('message')){
echo "<div class='message'>".$this->session->flashdata('message')."</div>";
}
if (count($vehicle))
    {
    echo "<table border='1' cellspacing='0' cellpadding='3' width='400' > \n";
    echo " <tr valign='top' > \n";
    echo " <th>Year</th><th>Model Name</th><th>Type</th><th>Actions</th>\n";
    echo " </tr>";
        foreach ($vehicle as $key => $list)
    {
    echo "<tr valign='top'>";
    echo "<td>".$list['year']."</td>";
    echo "<td> ".$list['modelName']."</td>";
    echo "<td> ".$list['carType']."</td>";
    echo "<td align='center'>";
    echo anchor('vehicle/edit/'.$list['caryearID'],'edit');
    echo "</td>\n";
    echo "</tr>\n";
    }
    echo "</table>";
}
    echo $this->pagination->create_links();
    echo '</p>';
?&gt;

By the way, here is the error output when you used the pagination links

Code:
