codeigniter实现get分页的方法

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。
