thinkphp增加每页显示条数的方法
4189
需求是多加一个类似phpmyadmin一样的每页显示条数,在网上查了好久都没找到,看到thinkphp分页类是html拼接的,很low,但是方便了我修改没,就在原生分页类基础上新定义了一个num变量,show方法返回的时候 thinkphp拼接html的地方,新加了一段选择条数的代码,如下:
- return "<ul class='am-pagination am-pagination-right'>{$page_str}</ul>
- <div class='am-dropdown am-dropdown-up' data-am-dropdown>
- <button class='am-btn am-btn-primary am-dropdown-toggle' data-am-dropdown-toggle>显示条数 <span class='am-icon-caret-up'></span></button>
- <ul class='am-dropdown-content'>
- <li><a href='".$this->urlNum(10,1)."'>10</a></li>
- <li><a href='".$this->urlNum(30,1)."'>30</a></li>
- <li><a href='".$this->urlNum(50,1)."'>50</a></li>
- </ul>
- </div>";
然后新加的urlNum方法是这样:
- private function urlNum($num,$page){
- $str = str_replace(urlencode('[PAGE]'), $page, $this->url);
- return str_replace(urlencode('[NUM]'), $num, $str);
- }
开始的时候由于page这个变量 thinkphp会先变一个转码的,后面才替换;而且page=1的时候 url里是不显示的,但是还有这个参数,导致num这个变量老是搞得url 很不稳定、经常叠加。
后面只有做了一个小牺牲(选定每页显示条数的时候 url page即使为1 也会加上),不过这并没有什么影响。
整个代码分页类 就是这样:
