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);

}
