Show one sidebar else don't show any sidebar

Question

我只需要一个侧边栏页面，否则不显示任何侧边栏留空

**<?php get_sidebar("wp-forecast") ?>** 

Answer 1

You could add a flag variable and set it to false:

 $displayed_sidebar = false

Then wrap the content of the function get_sidebar in a condition that checks if displayed_sidebar is false or not:

 if (!$displayed_sidebar) {

     $displayed_sidebar = true; // this prevents more than one sidebar to be displayed

     // ... the rest of the code here ...   

 }
