我尝试使用分页创建搜索。我能做到,当我去第二页不是问题,但当我去第三页数据丢失。 请帮我。这是我的控制器代码:
function fast_search() {
$data = array(
'reason' => $this->input->post('reason'),
'shahr' => $this->input->post('shahr'),
'file_type' => $this->input->post('file_type'),
'region' => $this->input->post('region'),
'neighbourhood' => $this->input->post('neighbourhood'),
'under_build_area' => $this->input->post('under_build_area'),
'user_type' => $this->input->post('user_type')
);
$this->session->set_flashdata($data);
/*-------------------------------------------------------*/
$page = ($this->uri->segment(4)) ? $this->uri->segment(4) : 0;
if ($page == 0)
{
$config = array();
$config['base_url'] = base_url() . 'file/fast_search/page';
$config['per_page'] = 9;
$config['uri_segment'] = 4;
$config['total_rows'] = count($this->file_model->fast_search($data));
$this->pagination->initialize($config);
$data['results'] = $this->file_model->fast_search($data, $config['per_page'], $page);
$data['links'] = $this->pagination->create_links();
} else {
$this->session->keep_flashdata('reason');
$this->session->keep_flashdata('shahr');
$this->session->keep_flashdata('file_type');
$this->session->keep_flashdata('region');
$this->session->keep_flashdata('neighbourhood');
$this->session->keep_flashdata('under_build_area');
$this->session->keep_flashdata('user_type');
$result_data = array(
'reason' => $this->session->flashdata('reason'),
'shahr' => $this->session->flashdata('shahr'),
'file_type' => $this->session->flashdata('file_type'),
'region' => $this->session->flashdata('region'),
'neighbourhood' => $this->session->flashdata('neighbourhood'),
'under_build_area' => $this->session->flashdata('under_build_area'),
'user_type' => $this->session->flashdata('user_type')
);
$config = array();
$config['base_url'] = base_url() . 'file/fast_search/page';
$config['per_page'] = 9;
$config['uri_segment'] = 4;
$config['total_rows'] = count($this->file_model->fast_search($result_data));
$this->pagination->initialize($config);
//$this->dvd($result_data);
$data['results'] = $this->file_model->fast_search($result_data, $config['per_page'], $page);
$data['links'] = $this->pagination->create_links();
}
/*-------------------------------------------------------*/
//$this->dvd($data['links']);
if ($data['results'] != FALSE)
{
$data['agency_nums'] = $this->user_model->get_registered_agency();
$data['updated_agencies'] = $this->user_model->get_uplated_agencies();
$data['count_files'] = $this->file_model->count_files();
$this->load->view('fast_search', $data);
//return $data;
} else {
$data['error'] = 'No Result !';
$data['agency_nums'] = $this->user_model->get_registered_agency();
$data['updated_agencies'] = $this->user_model->get_uplated_agencies();
$data['count_files'] = $this->file_model->count_files();
$this->load->view('fast_search', $data);
}
}
我使用会话功能,如: $这 - >会话而> set_flashdata($数据); $这 - >会话而> keep_flashdata( '理由');

嗨,我非常喜欢这个关于CI中搜索的net.tuts教程,它真的很好,你不需要使用会话来保存和检索搜索数据,你需要扩展你的输入类,它将保存关键字和搜索条件在数据库中为您提供了已保存记录的id和id,您可以在分页中使用这个记录,看看这个非常棒的教程

如果你在下一页设置这样的会话时因为$ data是没有数据(帖子只发送一个),我认为你设置的条件就像那样
$is_search = $this->input->post('search'); // name button search
if (!array_filter($data) && $is_search===false) { // check array is empty and no search value (only submit form have search name)
$data = array(
'reason' => $this->session->userdata('reason'),
'shahr' => $this->session->userdata('shahr'),
'file_type' => $this->session->userdata('file_type'),
'region' => $this->session->userdata('region'),
'neighbourhood' => $this->session->userdata('neighbourhood'),
'under_build_area' => $this->session->userdata('under_build_area'),
'user_type' => $this->session->userdata('user_type')
);
} else {
$this->session->set_userdata( $data ); // create new session
}
/*-------------------------------------------------------*/
$page = ($this->uri->segment(4)) ? $this->uri->segment(4) : 0;
