Theres not enough info here for us to help you I'm afraid. For example we don't know what $menu_links is like, and we don't know how you are processing the $_POSTed data. Sorry. — Antony

I have tried this code in your Page_model put this code.

public function input_values(){
$checkbox = implode(',', $this->checkBox());
$data = array(
    'lang_id' => $this->input->post('lang_id', true),
    'title' => $this->input->post('title', true),
    'slug' => $this->input->post('slug', true),
    'page_description' => $this->input->post('page_description', true),
    'page_keywords' => $this->input->post('page_keywords', true),
    'page_content' => $this->input->post('page_content', false),
    'parent_id' => $this->input->post('parent_id', true),
    'page_active' => $this->input->post('page_active', true),
    'title_active' => $this->input->post('title_active', true),
    'breadcrumb_active' => $this->input->post('breadcrumb_active', true),
    'need_auth' => $this->input->post('need_auth', true),
    'howmany_people' => $this->input->post('howmany_people', true),
    'difficulty' => $this->input->post('difficulty', true),
    'howmany_time' => $this->input->post('howmany_time', true),
    'location' => $this->input->post('location', true),
    'subcat_recip_id' => $checkbox
);
}

public function checkBox(){
$count = count($_POST['subcat_recip_id']);
for($n=0; $n<$count; $n++){
$checkbox[$n] = $_POST['subcat_recip_id'][$n];
}
return $checkbox;
}

hopefully it helps

Now it doesn't add nothing to DB, only NULL fields. Does it need a return $data?

Hip Hura Over a year ago

can you post the result var_dump($data);die; on input_values(){ var_dump($data);die; }

Sal Over a year ago

Hip Hura: Where I add var_dump? inside form in view page or inside controller function? Tks

Hip Hura Over a year ago

inside your controller, before close your function, btw did you test another way answer box?

Sal Over a year ago

I updated all files you should need to check where I wrong. TKS

This is what $menu_links is:

public function get_menu_links_by_lang()
{
    $lang_id = $this->input->post('lang_id', true);
    if (!empty($lang_id)):
        $menu_links = $this->navigation_model->get_menu_links_by_lang($lang_id);
        foreach ($menu_links as $item):
            if ($item["type"] != "category" && $item["location"] == "header" && $item['parent_id'] == "0"):
                echo ' <option value="' . $item["id"] . '">' . $item["title"] . '</option>';
            endif;
        endforeach;
    endif;
}

I edited a code to insert new form page and I need this page to enter some values into DB. All works Ok and they inserted to DB, only the checkbox doesn't work or better it take only the value of the last checked checkbox and not all the checkbox checked! I have tried it in many ways but I can't do it alone. Sorry.
