我的代码有问题,我想按2类过滤。但在我所做的工作中,只需过滤一个类别就可以工作,而过滤其他类别也无效。有人可以帮我解决这个问题吗?
这是我的控制器
public function index($state = null , $category = null)
{
if (!empty($state)) {
$this->load->model('M_kegiatan');
$data['username'] = $this->session->userdata('username');
$data['kegiatan'] = $this->M_kegiatan->get_status($state);
$this->load->view('beranda', $data);
}else if (!empty($category)) {
$this->load->model('M_kegiatan');
$data['username'] = $this->session->userdata('username');
$data['kegiatan'] = $this->M_kegiatan->get_kategori($category);
$this->load->view('beranda', $data);
} else {
$this->load->model('M_kegiatan');
$data['username'] = $this->session->userdata('username');
$data['kegiatan'] = $this->M_kegiatan->get_kegiatan();
$this->load->view('beranda', $data);
}
这是我的模特:
public function get_status($status) {
$this->db->order_by('tanggal','desc');
$this->db->where('status',$status);
$query = $this->db->get('kegiatan');
if ($query->num_rows() > 0) {
return $query -> result();
}
}
public function get_kategori ($kategori) {
$this->db->order_by('tanggal','desc');
$this->db->where('kategori',$kategori);
$query = $this->db->get('kegiatan');
if ($query->num_rows() > 0) {
return $query -> result();
}
}
从这段代码中,只需按get_status()过滤即可,任何人都可以帮助我吗?
答案 0 :(得分:0)
如果我理解正确,我认为这就是你要找的。 p>
public function get_filtered ($status, $category)
{
$this->db->order_by('tanggal','desc');
If (!empty($status))
{
$this->db->where('status',$status);
}
If (!empty($category))
{
$this->db->where('kategori',$category);
}
$query = $this->db->get('kegiatan');
return ($query->num_rows() > 0) ? $query->result() : NULL;
将此功能添加到模型
function myFunction() {
window.open("mydomain/?a=" + document.getElementById('text-one').value + '&b=' + document.getElementById('text-two').value + '&c=' + document.getElementById('text-three').value;
}
