php, tp5, 选中导航菜单

1. 首先定义一个函数:

function nav_select($navindex){
    $nav_arr = [
        1 => ['index',],
        2 => ['mei',],
        3 => ['quan','write'],
        4 => ['my',],
    ];
    $navarr = $nav_arr[$navindex];
    if(in_array(ACTION_NAME, $navarr)){
        echo ' nav-on ';
    }
}

　　　

2. 然后在模板里调用：

<a href='xxx' class='{:nav_select(1)}'>导航1</a>

;
