and I try to make the same as he recommends
here is my controller

Code:

public function rechercher ()
{

  


     /* ici je tente de les recuperer */
       $province=$this->input->post('province');
       if(strlen($province)>0){
           $this->session->set_userdata('province',$province);
       }
      
       $province = $this->session->userdata('province');
      
      
       $categorie=$this->input->post('categorie');
       if(strlen($province)>0){
           $this->session->set_userdata('categorie',$categorie);
       }
      
       $categorie = $this->session->userdata('categorie');
      
      
      
      
      
      
       /* necessaire pour la pagination */
     $offset = $this->uri->segment(3);
            $limit = 2 ;
      
      
           $config['base_url']='http://localhost/MonSite/index.php/annonce/rechercher';
          
    
          
            $config['total_rows']= $this->annoncemodel->getRowAnnonceRecherche($province,$categorie);
            
            $config['num_links']=5;  
            
            $config['per_page']= $limit;
            
            $config['full_tag_open']='<div id="pagination">';
            
             $config['full_tag_close']='</div>';
            
             $config['next_link']='>>';
            
              $config['prev_link']='<<';
              
              $this->pagination->initialize($config);
              
              
              $data['infos'] = $this->annoncemodel->getAnnonceRecherche($province,$categorie,$config['per_page'],$offset);
              
            
          
          
             /*on l'envoie à la vue de nouveau */      
      
      
      
              $this->load->view('principalannonce',$data);
              
              
      
      
      
      


}

I can only see one thing, you have no:

Code:

$config['uri_segment'] = 3; //Set to value of offset.

No because $offset is just a variable and isn't picked up by the pagination class. The pagination initialise function needs to know where to stick the offset part.

Code:

$data['infos'] = $this->annoncemodel->getAnnonceRecherche($province,$categorie,$config['per_page'],$this->uri->segment(3));

thank you so much guy it works for someone who have the same problem I proceed like that

Code:

public function rechercher ()
{

  


     /* ici je tente de les recuperer */
       $province=$this->input->post('province');
       if(strlen($province)>0){
           $this->session->set_userdata('prov',$province);
       }
      
       $province2 = $this->session->userdata('prov');
      
      
       $categorie=$this->input->post('categorie');
       if(strlen($province)>0){
           $this->session->set_userdata('cate',$categorie);
       }
      
       $categorie2 = $this->session->userdata('cate');
      
      
       $config['uri_segment']=3;
      
      
      
       /* necessaire pour la pagination */
     $offset = $this->uri->segment(3);
            $limit = 2 ;
      
      
           $config['base_url']='http://localhost/MonSite/index.php/annonce/rechercher';
          
      $config['per_page']= $limit;
          
            $config['total_rows']= $this->annoncemodel->getRowAnnonceRecherche($province2,$categorie2);
            
                 $data['infos'] = $this->annoncemodel->getAnnonceRecherche($province2,$categorie2,$config['per_page'],$offset);
            
       /* pgination */
            
            $config['num_links']=5;  
            
            $config['per_page']= $limit;
            
            $config['full_tag_open']='<div id="pagination">';
            
             $config['full_tag_close']='</div>';
            
             $config['next_link']='>>';
            
              $config['prev_link']='<<';
              
              $this->pagination->initialize($config);
        
            
          
             /*on l'envoie à la vue de nouveau */      
                
                
              
      
                
                



            $this->pagination->initialize($config);
            $data['pag_links'] = $this->pagination->create_links();
            
            
    
      
      
              $this->load->view('principalannonce',$data);
              
              
      
      
      
      


}

so I must change the name of the variable here

$categorie2 = $this->session->userdata('cate');

thank you so much

I really didn't understand this because there was just a line of code and no explanation. If this line is incorrect I don't know why and I can't read it because I don't speak the language.

What do you not get with this code?

Code:

// $config['per_page'] = LIMIT
// $this->uri->segment(3)) = OFFSET to start at
$data['infos'] = $this->annoncemodel->getAnnonceRecherche($province,$categorie,$config['per_page'],$this->uri->segment(3));

[/quote]
of course it is the same result :

Code:

$data['infos'] = $this->annoncemodel->getAnnonceRecherche($province2,$categorie2,$config['per_page'],$this->uri->segment(3));

and

$offset = $this->uri->segment(3);

Code:

$data['infos'] = $this->annoncemodel->getAnnonceRecherche($province2,$categorie2,$config['per_page'],$offset);

for explain :

in my model I have something like that :

Code:

public  function getAnnonceRecherche ($province,$categorie,$limit ,$offset)
{
    $this->db->select('idannonce,nom_path,prix,nom_categorie,nom_ville,titre');
     $this->db->from('annonce');
     $this->db->join('ville', 'ville.idville = annonce.identifiant_ville');
     $this->db->join('categorie', 'categorie.idcategorie = annonce.identifiant_categorie');
     $this->db->join('image', 'image.identifiant_annonce = annonce.idannonce');
    
      $this->db->where('identifiant_categorie', $categorie);
      $this->db->where('identifiant_region', $province);
    
    
     $this->db->order_by("idannonce", "desc");
       $this->db->limit($limit,$offset);
      
      
     $query = $this->db->get();
    
     if($query->num_rows()>0)
      {
       foreach($query->result_array()as $row)
        {
         $data[] = $row;
        }
        
      
                          
        return $data;
     }
      
      
}

so we nedd to pass parameter in function getAnnonceRecherche ($province,$categorie,$limit ,$offset)

French? Again, you didn't explain anything.
