控制器方法代码
public function index(Request $request)
{
//明白了明白了，为什么要使用appends把参数配置上
//$request->input取得是url参数的值，把参数拼进去。再点击下一页的时候就链接跳转进入控制器处理，就可以获取到查询条件了。
//获取到文本域输入的值
$selects = $request->input('selects');
$students = Student::where('name', 'like', '%' . $selects . '%')->paginate(5);
//把$selects传入视图，当作参数条件循环使用
return view('student.index', [
'students' => $students,
'selects' => $selects
]);
}
Blade 分页处代码
{!! $students->appends(['selects' => $selects])->render() !!}
//上面代码如此简洁的代码是框架内置的好
//把上面代码打印显示结果：

//此处就是模糊查询 1 后，下一页 处的链接，触发链接控制器处理数据，再返回就实现了。
