如何在codeigniter中创建搜索功能

Question

我想创建简单的搜索功能。我遵循一些例子。但我无法得到结果。请帮我。

//查看页面

<form class="navbar-form" role="search" action=" {{ base_url }}search/search_keyword" method = "post">
    <div class="input-group">
        <input type="text" class="form-control" placeholder="Search" name = "keyword"size="15px; ">
        <div class="input-group-btn">
            <button class="btn btn-default " type="submit" value = "Search"><i class="glyphicon glyphicon-search"></i></button>
        </div>
    </div>
</form>

//控制器

function search_keyword()
{
    $keyword    =   $this->input->post('keyword');
    $data['results']    =   $this->mymodel->search($keyword);
    $this->twig->display('result_view.php',$this->data);
    //$this->load->view('result_view.php',$data);
}

}

//模型

function search($keyword)
{
    $this->db->like('item_name',$keyword);
    $query  =   $this->db->get('bracelets');
    return $query->result();
}

Answer 1

改变

 $this->twig->display('result_view.php',$this->data);

到

 $this->load->view('result_view.php',$data);

Answer 2

使用此功能

function search_keyword()
{
    $keyword=$this->input->post('keyword');
    $data['results']=$this->mymodel->search($keyword);
    $this->twig->display('result_view.php',$data);
}
