CodeIgniter method to implement get paging _php skills

The example in this article describes how CodeIgniter implements get paging. Share to everyone for your reference. The implementation method is as follows:

Public Function Project_search () {$this->load->library (' pagination ');
  $this->load->model (' depart_mdl ');
  Get the information that the search needs $data = $this->get_project_data ();
  $get _data = $this->input->get ();
  $data = Array_merge ($data, $get _data);
  Get paging configuration $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;
  Offset $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 ', $get _data[' Bidder_way ')); 
  }//Time if ($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 '], $page _from)->get ()->result_array ();
 Processing For ($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; Gets the role of the current user $data [' user_role '] = $this->user_mdl->get_user_by_salary_no ($this->session->userdata ('  
  Salary_no ')->role;
$this->_template (' Project_search ', $data);
