当我在控制器中访问错误的功能时,404错误页面运行良好。但是,当我访问类似“http://example.com/model/detail/116”的URL时,哪个116号错误[不在数据库中],我的404错误页面无效。
我的控制器中有这个代码:
public function detail()
{
$id['id_galeri'] = $this->uri->segment(3);
$detail = $this->app_model->getSelectedData("tbl_galeri",$id);
foreach($detail->result() as $d)
{
$bc['jdl'] = "View";
$bc['id_galeri'] = $d->id_galeri;
$bc['nama'] = $d->nama;
$bc['foto'] = $d->foto;
$bc['deskripsi'] = $d->deskripsi;
$bc['stts_input'] = "deskripsi";
}
if($this->uri->segment(3) == '' && $id['id_galeri'] == FALSE)
{
$segment_url = 0;
}else{
if(!is_numeric($this->uri->segment(3)) || !is_string($this->uri->segment(3))){
redirect('404');
}else{
$segment_url = $this->uri->segment(3);
}
}
$this->load->view('frontend/global/bg_top');
$this->load->view('frontend/page/bg_view_model',$bc);
$this->load->view('frontend/global/bg_footer');
}
抱歉我的英文不好,请帮忙:-) 谢谢..
答案 0 :(得分:1)
而不是:
redirect('404');
尝试使用CodeIgniter's native:
show_404('page');
修改强>
尝试使用此代码,稍微清理一下并在保存视图之前完成检查。
public function detail()
{
$id['id_galeri'] = $this->uri->segment(3);
// Check if the supplied ID is numeric in the first place
if ( ! is_numeric($id['id_galeri']))
{
show_404($this->uri->uri_string());
}
// Get the data
$detail = $this->app_model->getSelectedData("tbl_galeri",$id);
// Check if any records returned
if (count($detail->result()) === 0)
{
show_404($this->uri->uri_string());
}
foreach($detail->result() as $d)
{
$bc['jdl'] = "View";
$bc['id_galeri'] = $d->id_galeri;
$bc['nama'] = $d->nama;
$bc['foto'] = $d->foto;
$bc['deskripsi'] = $d->deskripsi;
$bc['stts_input'] = "deskripsi";
}
/**
* Here do whatever you want with the $segment_url which doesn't seem to be
* used in your code
*/
$this->load->view('frontend/global/bg_top');
$this->load->view('frontend/page/bg_view_model',$bc);
$this->load->view('frontend/global/bg_footer');
}
