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：
publicfunctionproject_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。
