這篇文章主要介紹了codeigniter實現get分頁的方法,涉及使用codeigniter框架查詢數據量及針對結果集進行get方法分頁的相關技巧,非常簡單實用,需要的朋友可以參考下

本文實例講述了codeigniter實現get分頁的方法。分享給大家供大家參考。具體實現方法如下：

1. public function project_search(){ 
2. $this->load->library('pagination'); 
3. $this->load->model('depart_mdl'); 
4. //獲取搜索需要的信息 
5. $data = $this->get_project_data(); 
6. $get_data = $this->input->get(); 
7. $data = array_merge($data,$get_data); 
8. //get分頁配置 
9. $name = $get_data['name']; 
10. $username = $get_data['username']; 
11. $budget = $get_data['budget']; 
12. $type = $get_data['type']; 
13. $posttime_start = $get_data['posttime_start']; 
14. $posttime_end = $get_data['posttime_end']; 
15. $purchase_type = $get_data['purchase_type']; 
16. $depart_code = $get_data['depart_code']; 
17. $project_status = $get_data['project_status']; 
18. $bidder_way = $get_data['bidder_way']; 
19. $suffix = "?name=$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"; 
20. $config['base_url'] = site_url('project/project_search').$suffix; 
21. $config['total_rows'] = $this->db->count_all($this->db->dbprefix('project')); 
22. $config['per_page'] = 10; 
23. $config['page_query_string'] = TRUE; 
24. //偏移量 
25. $config['query_string_segment'] = 'page'; 
26. $config['uri_segment'] = 3; 
27. $this->pagination->initialize($config); 
28. $user = $this->user_mdl->get_user_by_salary_no($this->session->userdata('salary_no')); 
29. $this->db->from('ustc_project'); 
30. $this->db->join('ustc_admins','ustc_admins.salary_no=ustc_project.salary_no'); 
31. if($user->role!=1){ 
32. $depart_code = explode(',',$user->grant_depart_code); 
33. $this->db->where_in('grant_depart_code',$depart_code); 
34. $this->db->or_where('ustc_project.salary_no =',$this->session->userdata('salary_no')); 
35. } 
36. if($name != ''){ 
37. $this->db->like('name',$name); 
38. } 
39. if($username != ''){ 
40. $this->db->like('username',$get_data['username']); 
41. } 
42. if($budget != ''){ 
43. $this->db->like('budget',$get_data['budget']); 
44. } 
45. if($type != ''){ 
46. $this->db->where('type',$get_data['type']); 
47. } 
48. if($depart_code != ''){ 
49. $this->db->where('depart_code',$get_data['depart_code']); 
50. } 
51. if($purchase_type != ''){ 
52. $this->db->where('purchase_type',$get_data['purchase_type']); 
53. } 
54. if($project_status != ''){ 
55. $this->db->where('project_status',$get_data['project_status']); 
56. } 
57. if($bidder_way != ''){ 
58. $this->db->where('bidder_way',$get_data['bidder_way']); 
59. } 
60. //時間 
61. if($posttime_start != ''){ 
62. $this->db->where('posttime > ',strtotime($get_data['posttime_start'])); 
63. } 
64. if($posttime_end != ''){ 
65. $this->db->where('posttime < ',strtotime($get_data['posttime_end'])); 
66. } 
67. if(isset($get_data['page'])){ 
68. $page_from = $get_data['page']; 
69. }else{ 
70. $page_from = 0; 
71. } 
72. $this->db->order_by('posttime','desc'); 
73. $projects = $this->db->limit($config['per_page'],$page_from)->get()->result_array();  
74. //處理 
75. for($i=0;$i<count($projects);$i++){ 
76. $projects[$i]['type'] = $this->manage_info_mdl->get_value_by_id($projects[$i]['type'])->value; 
77. $projects[$i]['purchase_type'] = $this->manage_info_mdl->get_value_by_id($projects[$i]['purchase_type'])->value; 
78. $projects[$i]['depart'] = $this->depart_mdl->get_depart_by_code($projects[$i]['depart_code'])->name; 
79. } 
80. $data['projects'] = $projects; 
81. //獲取當前用戶的角色 
82. $data['user_role'] = $this->user_mdl->get_user_by_salary_no($this->session->userdata('salary_no'))->role;  
83. $this->_template('project_search',$data); 
84. } 

希望本文所述對大家基于codeigniter的php程序設計有所幫助。
