tp5页面输出时，搜索功能在跳转下一页时，如果不做任何处理，会返回原有是第二页输出的数据。为了保证跳转下一页时输出的是搜索到的数据，做以下处理。
（要根据自己的搜索字段进行适当修改）
页面js代码，给地址栏加上参数，以便于点击搜索按钮后台通过地址栏得到搜索条件。
$(document).ready(function(){ //点击搜索按钮执行搜索 $("#search").click(function() { var form = $('#form'); var url = form.attr('action'); var query = $('.key').serialize(); query = query.replace(/(&|^)(\w*?\d*?\-*?_*?)*?=?((?=&)|(?=$))/g, ''); query = query.replace(/^&/g, ''); if (url.indexOf('?') > 0) { url += '&' + query; } else { url += '?' + query; } form.attr('action',url); }); //回车搜索 $(".search-form").keyup(function(e) { if (e.keyCode === 13) { $(".search").click(); return false; } }); //设定input框的值，保留搜索条件，setValue的方法参照 setValue('shop_id', "{:input('get.shop_id')}"); setValue('key', "{:input('get.key')}"); })
搜索部分页面html代码
控制器主要代码
if (empty(input('get.'))) { $page = NewsModel::where('isdelete',1)->order('id desc')->paginate(8); $this->assign('list',$page); return $this->fetch();} else { $shop_id=input('get.shop_id'); $key=input('get.key'); if ($shop_id=='all' && $key != '') { $page=NewsModel::where(['title'=>['like',"%$key%"],'isdelete'=>['eq',1]])->order('id desc')->paginate(8,false,[ 'query' => ['shop_id' => $shop_id,'key' => $key] //url额外参数 ]); } elseif ($shop_id != 'all' && $key != '') { $page=NewsModel::where(['title'=>['like',"%$key%"],'shop_id'=>['eq',$shop_id],'isdelete'=>['eq',1]])->order('id desc')->paginate(8,false,[ 'query' => ['shop_id' => $shop_id,'key' => $key] ]); } elseif ($shop_id != 'all' && $key == '') { $page=NewsModel::where(['shop_id'=>['eq',$shop_id],'isdelete'=>['eq',1]])->order('id desc')->paginate(8,false,[ 'query' => ['shop_id' => $shop_id,'key' => $key] ]); } else { $page=NewsModel::where('isdelete',1)->order('id desc')->paginate(8,false,[ 'query' => ['shop_id' => $shop_id,'key' => $key] ]); } $this->assign('list',$page); return $this->fetch();}
