Help Me... Search with dropdown menu or radio button

[eluser]myrna[/eluser]
I'm making a search function.

Model

Code:

<?php
    class PencarianModel extends Model
    {    
        function PencarianModel()
        {
            parent::Model();
        }    
        
        function SearchResult($perPage,$uri,$judul)
        {
            $this->db->select('*');
            $this->db->from('tbl_master_properti');
            if(!empty($judul)) {
                $this->db->like('judul',$judul);
            }
            $this->db->order_by('id_master_properti','asc');
            $getData = $this->db->get('', $perPage, $uri);
            
            if($getData->num_rows() > 0)
                return $getData->result_array();
            else
                return null;
        }
    }
?>

controller

Code:

<?php
    class Search extends Controller
    {    
        function Search()
        {
            parent::Controller();    
        }
        
        function index()
        {
            if(isset($_POST['submit']))
            {
                $data['judul'] = $this->input->post('judul');
                $this->session->set_userdata('sess_judul', $data['judul']);
            } else {
                $data['judul'] = $this->session->userdata('sess_judul');
            }
            
            $this->db->like('judul', $data['judul']);
            $this->db->from('tbl_master_properti');
            
            $pagination['base_url']=base_url().'index.php/ulang37/index/page/';
            $pagination['total_rows']     = $this->db->count_all_results();
            $pagination['full_tag_open'] = "<p><div class=\"pagination\">";
            $pagination['full_tag_close'] = "</div></p>";
            $pagination['cur_tag_open'] = "<span class=\"current\">";
            $pagination['cur_tag_close'] = "</span>";
            $pagination['num_tag_open'] = "<span class=\"disabled\">";
            $pagination['num_tag_close'] = "</span>";
            $pagination['per_page']     = "100";
            $pagination['uri_segment'] = 4;
            $pagination['num_links']     = 4;
            
            $this->pagination->initialize($pagination);
            
            $data['ListBerita'] = $this->pencarianmodel->SearchResult($pagination['per_page'],$this->uri->segment(4,0),$data['judul']);
            $data['current'] = 'search';
            $data['content'] = 'pencarian';
            $this->load->vars($data);
            $this->load->view('container', $data);
            }
    }
?&gt;

view

Code:

<div class="clear"></div>
<div id="content_box" class="grid_24 box">
&lt;form id="form_pencarian" name="form_pencarian" method="post" action="&lt;?=base_url();?&gt;/search/"&gt;
  &lt;input name="judul" type="text" id="judul" size="30" maxlength="255" class="inputbox" value="&lt;?=$judul;?&gt;"/&gt;&nbsp;&nbsp;
  &lt;input name="submit" type="submit" id="submit" value="Cari" class="button"/&gt;
&lt;/form&gt;
<hr />
&lt;?php
    
    if(count($ListBerita) > 0) {
        foreach($ListBerita as $row)
        {
            echo "<div class=\"letter\">";
            echo "<table cellspacing=\"0\" cellpadding=\"0\" border=\"0\">
                <tbody>";
            echo "<tr>
                        <td width=32 align=\"center\" valign=\"middle\">&nbsp;</td>
                        <td width=500>
                        <span>". $row['pengarang'] ."</span><br/>
                        <a >".$row['id_kategori']."</a>
                        <div> ".$row['judul']."</div>
                        </td>
                </tr>";
            echo "</tbody></table>";    
            echo "</div>";
        }
        echo $this->pagination->create_links();
    } else {
        echo "<div><strong>No result.</strong></div>";
    }
?&gt;
</div>
<div class="clear"></div>
&lt;/body&gt;
&lt;/html&gt;

If I want to add a dropdown menu or radio buttons on my program. what should I add to my program?

Code:

$criteria = array();
$query = "";

$i = 0;
if (!empty($judul))
$criteria[$i++] = "judul LIKE $judul";

if (!empty($editor))
$criteria[$i++] = "editor LIKE $editor";

if (!empty($pengarang))
$criteria[$i++] = "pengarang LIKE $pengarang";

$query = $criteria[0];
for ($i = 1; $i < size($criteria) - 1; $i++)
{
$query .= " AND " + $criteria[$i];
}

echo $query;

If I want to add the code above. what must I change on the model, view and controllernya?

Thanks for your help.

Hmmm ... how did you get so far and then not know how to add extra criteria to your search?

anyway - hopefully this will get you started (it isn't complete code, only enough to give you some clues!)

Model

Code:

function SearchResult($perPage,$uri,$judul,$editor,$pengarang)
{
    $this->db->select('*');
    $this->db->from('tbl_master_properti');
    if(!empty($judul)) {
        $this->db->like('judul',$judul);
    }
    if(!empty($editory)) {
        $this->db->like('editor',$editor);
    }
    if(!empty($pengarang)) {
        $this->db->like('pengarang',$pengarang);
    }

controller

Code:

function index()
{
    if(isset($_POST['submit']))
    {
        $data['judul'] = $this->input->post('judul');
        $this->session->set_userdata('sess_judul', $data['judul']);
        $data['editor'] = $this->input->post('editor');
        $this->session->set_userdata('sess_editor', $data['editor']);
        $data['pengarang'] = $this->input->post('pengarang');
        $this->session->set_userdata('sess_pengarang', $data['pengarang']);
        
    //...
    
    // pass the extra post data to your model
    $data['ListBerita'] = $this->pencarianmodel->SearchResult($pagination['per_page'],$this->uri->segment(4,0),$data['judul'],$data['editor'],$data['pengarang']);
    
    //...
    }

view

Code:

<input name="editor" type="text" id="editor" size="30" maxlength="255" class="inputbox" value="<?=$editor;?>"/>

<!-- or for a select (dropdown): -->

<select name="editor" id="editor">
    <option value="some_value">Editor One</option>
    <option value="some_value2">Editor Two</option>
    <option value="some_value3">Editor Three</option>
</select>

Thanks for the help, Flemming. I actually just learning CI and I'm making a final project in college and my teacher suggested to use the CI. So, I have yet to understand in depth about the CI and the programs that I wrote above is a program from others that my modifications.

If I have any trouble may I ask you?

If you have any examples of the search function?

Thank you, sorry with my english not perfect.

[eluser]Flemming[/eluser]
yes, ask any questions and I or somebody else should be able to help.

just make sure you have a clear understanding of the basics of CI and MVC.

Try to keep things in the right place, then it will be easier for us to help you! :-)
