php CI框架学习笔记-分页实现程序
本文章是一个自己的对CI框架的学习笔记,用一个完整的搜索,查找并且实现分页的程序给大家参考参考。
举个按关键词搜索结果分页的例子,
1.视图HTML
代码如下 | 复制代码 |
|
即表单提交到名叫search的controller和名叫index的方法, 其中包含了一些动态参数,不是纯列表,故相对比较复杂,后面会提到。
代码如下 | 复制代码 |
public function index() { if (empty ( $offset )) { if (! empty ( $keyword )) { $per_page = 10; $this->pagination->initialize ( $config ); |
因为config.php中默认的enable_query_strings是false, 起始位置始终在最后,这样出来的结果类似/index.php/search/index/?s=中国/10,页码取不到,需要将此配置改为false;
3.模型
代码如下 | 复制代码 |
public function find_by_name($name, $per_page=0, $offset = 0, $is_total = false) { if ($is_total) {//总数 $query = $this->db->query ( "select count(id) as cnt from {$this->_book} where book_name like '%{$name}%'" ); if ($query->num_rows () > 0) { $row = $query->row (); $ret = $row->cnt; } }else{//列表 $query = $this->db->query ("select * from {$this->_book} where book_name like '%{$name}%' limit {$offset}, {$per_page}"); $ret = $query->result (); } return $ret; } |
