Hello, working with wordpress for the first time. I need to make the template and the data inside it switch by pressing the button, they say winter / summer

I decided to send a get request and, depending on it, set a cookie on which I can then write the conditions for the withdrawal, so I pass it this way,

<a href="<?php echo bloginfo('url')."?weather=summer"?>"> Лето </a>

in functions.php

 function codenode_set_weather(){ $weather = $_GET['weather']; switch($weather){ case "summer": case "winter": setrawcookie('weather', $weather, time()+3600 * 3); break; default: break; } } add_action('init', $codenode_set_weather);

and it seems to me that this is a very clumsy way of a crutch, can it be done more accurately? PS And by the way for some reason it does not work did not move in yet why

    and it seems to me that this is a very clumsy way of a crutch, can it be done more accurately?

    Welcome to WordPress. As far as I know, there is no additional convenient function for working with cookies, and the logic itself is too simple, everything is fine, except for the switch itself:

     if (isset($_GET['weather']) && in_array($_GET['weather'], array('summer', 'winter')) { setcookie('weather', $_GET['weather'], time() + (3600 * 3)); }
    • Thank you for your answer, and what do you think is bad in the switch? - 0xdef 10:51 pm
    • @ 0xdef, it is logically inapplicable here, and the operation performs rather strange for a switch. The same functionality. - etki

    I would like to clarify: the administrator changes the data or the user, by pressing the button?)

    At the moment I see myself the implementation of this task using two templates. It is much more convenient to give the user the choice of a template than to reinvent the wheel.

    • The user changes by pressing the button, changes the background image, slideshow, gallery. a lot of code duplication will be if you duplicate the entire template. Where to look to understand the "give the user a choice of 2 templates" - 0xdef
    • sooource.net/wordpress-theme-switcher is the first option that I found in google. Just using 2 themes makes it unnecessary for you to use additional crutch functions. I am for simplicity and elegance ... - cema93
