这篇文章主要介绍了codeigniter实现get分页的方法,涉及使用codeigniter框架查询数据量及针对结果集进行get方法分页的相关技巧,非常简单实用,需要的朋友可以参考下
本文实例讲述了codeigniter实现get分页的方法。分享给大家供大家参考。具体实现方法如下:
- public function project_search(){
- $this->load->library('pagination');
- $this->load->model('depart_mdl');
- //获取搜索需要的信息
- $data = $this->get_project_data();
- $get_data = $this->input->get();
- $data = array_merge($data,$get_data);
- //get分页配置
- $name = $get_data['name'];
- $username = $get_data['username'];
- $budget = $get_data['budget'];
- $type = $get_data['type'];
- $posttime_start = $get_data['posttime_start'];
- $posttime_end = $get_data['posttime_end'];
- $purchase_type = $get_data['purchase_type'];
- $depart_code = $get_data['depart_code'];
- $project_status = $get_data['project_status'];
- $bidder_way = $get_data['bidder_way'];
- $suffix = "?name=$name&username=$username&budget=$budget&type=$type&posttime_start=$posttime_start&posttime_end=$posttime_end&purchase_type=$purchase_type&depart_code=$depart_code&project_status=$project_status&bidder_way=$bidder_way";
- $config['base_url'] = site_url('project/project_search').$suffix;
- $config['total_rows'] = $this->db->count_all($this->db->dbprefix('project'));
- $config['per_page'] = 10;
- $config['page_query_string'] = TRUE;
- //偏移量
- $config['query_string_segment'] = 'page';
- $config['uri_segment'] = 3;
- $this->pagination->initialize($config);
- $user = $this->user_mdl->get_user_by_salary_no($this->session->userdata('salary_no'));
- $this->db->from('ustc_project');
- $this->db->join('ustc_admins','ustc_admins.salary_no=ustc_project.salary_no');
- if($user->role!=1){
- $depart_code = explode(',',$user->grant_depart_code);
- $this->db->where_in('grant_depart_code',$depart_code);
- $this->db->or_where('ustc_project.salary_no =',$this->session->userdata('salary_no'));
- }
- if($name != ''){
- $this->db->like('name',$name);
- }
- if($username != ''){
- $this->db->like('username',$get_data['username']);
- }
- if($budget != ''){
- $this->db->like('budget',$get_data['budget']);
- }
- if($type != ''){
- $this->db->where('type',$get_data['type']);
- }
- if($depart_code != ''){
- $this->db->where('depart_code',$get_data['depart_code']);
- }
- if($purchase_type != ''){
- $this->db->where('purchase_type',$get_data['purchase_type']);
- }
- if($project_status != ''){
- $this->db->where('project_status',$get_data['project_status']);
- }
- if($bidder_way != ''){
- $this->db->where('bidder_way',$get_data['bidder_way']);
- }
- //时间
- if($posttime_start != ''){
- $this->db->where('posttime > ',strtotime($get_data['posttime_start']));
- }
- if($posttime_end != ''){
- $this->db->where('posttime < ',strtotime($get_data['posttime_end']));
- }
- if(isset($get_data['page'])){
- $page_from = $get_data['page'];
- }else{
- $page_from = 0;
- }
- $this->db->order_by('posttime','desc');
- $projects = $this->db->limit($config['per_page'],$page_from)->get()->result_array();
- //处理
- for($i=0;$i<count($projects);$i++){
- $projects[$i]['type'] = $this->manage_info_mdl->get_value_by_id($projects[$i]['type'])->value;
- $projects[$i]['purchase_type'] = $this->manage_info_mdl->get_value_by_id($projects[$i]['purchase_type'])->value;
- $projects[$i]['depart'] = $this->depart_mdl->get_depart_by_code($projects[$i]['depart_code'])->name;
- }
- $data['projects'] = $projects;
- //获取当前用户的角色
- $data['user_role'] = $this->user_mdl->get_user_by_salary_no($this->session->userdata('salary_no'))->role;
- $this->_template('project_search',$data);
- }
希望本文所述对大家基于codeigniter的php程序设计有所帮助。
