Concept Question

[eluser]robert.fulcher[/eluser]
I have a form that submits for a search. I then get a listing page back. The listing page has links on it to a view page. I would like to have a link on the view page that would bring me back to the search results listing page. the search results is created through a submit function using post data. I can't set post data and link back to the submit function can I. The other solution is to create a new function to do the same search and read the uri string for the search variables.

What is the best way to do this?

Thanks

Typically, folks just put the search parameters/variables in the url. note google.

A very common approach is the following:

1.) user submits the form
2.) redirect to search/results/{keyword}

Look at the forum search, it's done very similar.

controller:

Code:

class Search extends Controller {

    function do_search()
    {
        $this->load->helper('url');
        $keyword = $this->input->post('keyword')
        redirect('/search/results/'.$keyword);
    }
    
    function results($keyword)
    {
        // do the actual searching here
        // query db, load views, etc.
    }

}

view:

Code:

<form action="/search/do_search/" method="POST">
<input type="text" name="keyword" />
<input type="submit" value="Search!">
</form>

Hi,

I`ll post a piece of my code... but i`m in a hurry, so I can`t explaint too much...

Here we go:

Code:

function busca() { // Search function. Here I prepare the search URL to send to browser
        $termos = array();
        if ($this->uri->segment(4)!='') { // Here mi search is already made before
            $search = $this->uri->segment(4);
            $search = str_replace(' ','-',$search);
            acento_nao($search); // removing accents, custom function
            // Preparando array
            $aux = explode('-',$search);
            foreach($aux as $key => $valor) { // $termos will be each search word
                $termos[] = $valor;
            }
        } else { // Search form sent!
            $search = $this->input->post('valor');
            $search = str_replace(' ','-',$search);
            acento_nao($search);
            // Preparando array
            $aux = explode('-',$search);
            foreach($aux as $key => $valor) {
                $termos[] = $valor;
            }
        }
        redirect('administracao/admin/pagina/1/'.$search); // Redirecting to THIS controller and sending to pagination with page 1 as parameter
        
    }
    
        
    function pagina($page='',$termos='') { // Pagination function
        
        if ($page=='') {
            $this->session->keep_flashdata('mensagem');
            redirect('administracao/admin/pagina/1');
        }
        
        if ($this->uri->segment(5)!='') {
            $termos = $this->uri->segment(5);
        }
        
        $this->load->library('pagination');
        
        $limit = 20;
        $offset = ($page-1)*$limit;
    

        if ($termos=='') {
        
            $this->db->limit($limit, $offset);
            $query = $this->db->get('administradores');
            $data['total'] = $query->num_rows();
            $search = '';

        } else {
            $search = str_replace(' ','-',$termos);
            // Preparando array
            $busca = array();
            $aux = explode('-',$search);
            foreach($aux as $key => $valor) {
                $busca[] = $valor;
            }
            $this->db->like('nome', $busca[0]);
            $this->db->or_like('login', $busca[0]);
            $this->db->or_like('email', $busca[0]);
            
            $tt = count($busca);
            if ($tt>0) {
                for ($j=1;$j<$tt;$j++) {
                    $this->db->or_like('nome', $busca[$j]);
                    $this->db->or_like('login', $busca[$j]);
                    $this->db->or_like('email', $busca[$j]);
                }
            }
            
            
            $query_tt = $this->db->get('administradores');

            $this->db->like('nome', $busca[0]);
            $this->db->or_like('login', $busca[0]);
            $this->db->or_like('email', $busca[0]);

            $tt = count($busca);
            if ($tt>0) {
                for ($j=1;$j<$tt;$j++) {
                    $this->db->or_like('nome', $busca[$j]);
                    $this->db->or_like('login', $busca[$j]);
                    $this->db->or_like('email', $busca[$j]);
                }
            }
            
            $this->db->limit($limit, $offset);
            $query = $this->db->get('administradores');
            $data['total'] = $query_tt->num_rows();
        
        }
        
        

        $config['base_url'] = base_url().INDEX.'administracao/admin/pagina/';
        $config['total_rows'] = $data['total'];
        $config['per_page'] = $limit;
        $config['uri_segment'] = 4;
        $config['num_links'] = 5;
        
        
        $this->pagination->initialize($config);
        
        $data['status'] = 'listar';
        $data['search'] = $search;
        $data['range_min'] = $offset;
        $data['range_max'] = $search;
        $data['search'] = $search;
        $data['num_de_paginas'] = round($data['total'] / $limit);
        $data['adm'] = $query;
        
        $this->load->view('administracao/admin',$data);
        
        
    }
