Wordpress - Display variable content based on variable in URL

问题

I have a wordpress platform and I am looking at displaying variable content on a page based on a variable in the url.

I have a 1 page website (www.vidlab.io) and i would like the section "GoPro Video Editing" to display information about GoPro video editing if the url is vidlab.io/?type=GoPro or information about wedding editing if the Url is vidlab.io/?type=wedding, and so on. I have read that you can use a get call, but not really sure how to have that information in the URL without getting a 404.

Any ideas on plugins to use? Or PHP that I can insert into the page to get this result?

That is easy.

You have to use two Wordpress functions.

add_rewrite_rule()

and

add_rewrite_tag()

First you include the add_rewrite_tag() function into your functions.php of your theme.

For Example:

function custom_rewrite_tag() {
  add_rewrite_tag('%food%', '([^&]+)');
  add_rewrite_tag('%variety%', '([^&]+)');
}
add_action('init', 'custom_rewrite_tag', 10, 0);

After that you have to choice one page of wordpress which contains your content. You have to use the page ID of this page.

Than you include the add_rewrite_rule() in your functions.php.

For Example:

 function custom_rewrite_rule() {
    add_rewrite_rule('^nutrition/([^/]*)/([^/]*)/?','index.php?page_id=12&food=$matches[1]&variety=$matches[2]','top');
  }
  add_action('init', 'custom_rewrite_rule', 10, 0);

Notice!:

After this you have to go to your settings -> permalinks and only push the save button to clean your permalink cache.

IMPORTANT: Do not forget to flush and regenerate the rewrite rules database after modifying rules. From WordPress Administration Screens, Select Settings -> Permalinks and just click Save Changes without any changes.

My example is from the codex page of wordpress:
