Hi. I'd like to make a update for my cars through website. Funny thing is I have 4 cars:
Peugeot
Citroen
Nissan
Renault

I've done everything the same for all 4 cars, but updating works just for Peugeot [lol]. Can you take a look and tell me what's wrong?

Peugeot[works]
Data which should be updated:

        if($peugeot)
    {
        foreach ($result as $value)
        {
             $value->model;
             $value->Opis;
             $value->year;
             $value->price;
        }
            echo form_open('main/editupdate');
            echo br(1);
            echo form_hidden('idpeugeot',$value->id);
            echo 'Model: ';
            echo br(1);
            echo form_input('modelpeugeot',$value->model);
            echo br(1);
            echo 'Link: ';
            echo br(1);
            echo form_input('linkpeugeot',$value->link);
            echo br(1);
            echo 'Opis: ';
            echo br(1);
            echo form_input('opispeugeot',$value->Opis);
            echo br(1);
            echo 'Rok: ';
            echo br(1);
            echo form_input('yearpeugeot',$value->year);
            echo br(1);
            echo 'Cena: ';
            echo br(1);
            echo form_input('pricepeugeot',$value->price);
            echo br(2);
            echo form_submit('peugot', 'Edytuj');
            echo form_close();

    }
Controller:

        $idpeugeot = $this->input->post('idpeugeot');
        $idcitroen = $this->input->post('idcitroen');
        $idnissan = $this->input->post('idnissan');
        $idrenault = $this->input->post('idrenault');


            $peugeot = array(
                    'model' => $this->input->post('modelpeugeot'),
                    'link' => $this->input->post('linkpeugeot'),
                    'opis' => $this->input->post('opispeugeot'),
                    'year' => $this->input->post('yearpeugeot'),
                    'price' => $this->input->post('pricepeugeot')
                );

Model:

            public function editpeugeot($peugeot,$idpeugeot)
        {

            $this->db->where('id', $idpeugeot);
            $this->db->update('cars', $peugeot);
        }


Code for other 3 cars:

        elseif ($citroen)
    {
        foreach ($result as $value)
        {
             $value->model;
             $value->Opis;
             $value->year;
             $value->price;
        }
            echo form_open('main/editupdate');
            echo br(1);
            echo form_hidden('idcitroen',$value->id);
            echo 'Model: ';
            echo br(1);
            echo form_input('modelcitroen',$value->model);
            echo br(1);
            echo 'Link: ';
            echo br(1);
            echo form_input('linkcitroen',$value->link);
            echo 'Opis: ';
            echo br(1);
            echo form_input('opiscitroen',$value->Opis);
            echo br(1);
            echo 'Rok: ';
            echo br(1);
            echo form_input('yearcitroen',$value->year);
            echo br(1);
            echo 'Cena: ';
            echo br(1);
            echo form_input('pricecitroen',$value->price);
            echo br(2);
            echo form_submit('citroen', 'Edytuj');
            echo form_close();

Controller: `               $citroen = array(
                    'model' => $this->input->post('modelcitroen'),
                    'link' => $this->input->post('linkcitroen'),
                    'opis' => $this->input->post('opiscitroen'),
                    'year' => $this->input->post('yearcitroen'),
                    'price' => $this->input->post('pricecitroen')
                );`

Model:

            public function editcitroen($citroen,$idcitroen)
        {

            $this->db->where('id', $idcitroen);
            $this->db->update('cxcxcx', $citroen);
        }

Everything is in the same files. But everything what i've done was for peugeot first. In the next step I just copied the code from peugeot and change the variables for other cars. Thank you for help
