Hooks on WordPress Edit Post Admin Page

There are hooks that allow you to display any content in a particular place on the admin page of adding or editing any type of post.

Thanks to hooks below, you can make the publication more convenient. All depends on your programming skills and imagination. For example:

  • Place video or text right before the visual editor with tips on writing content.
  • Show images already attached to the post as a slider.
  • Show photos from Google by keyword so you can choose one of them for a thumbnail.
  • Display a calculator for counting calories, if you publish a recipe post.
  • And much more that require your certain task and allow programming skills.

Config WP Super cache and Nginx

Standard WordPress-Nginx configuration with WP Super cache support:

As you are getting into Nginx, I hope you don’t need my help with configuring WP Super Cache plugin.

Still, make sure you are using “Use mod_rewrite to serve cache files. (Recommended)” option under “Advanced” tab.

Following configuration supports:

  1. Static Page Caching using Disk
  2. Direct browser cache for static content like images, js, css, etc

    https:https://thinhcoi.com/wp-content/uploadshttps://thinhcoi.com/wp-content/uploadsgist.github.comhttps://thinhcoi.com/wp-content/uploads21c4b021871d7607d8b1.git

    Note:

    To simplify configuration, I haven’t added Mobile user agent checks. We are in the iPhone era where finally phones are getting smart. So there is no need to create separate mobile site, when you can cater to today’s iPhonehttps://thinhcoi.com/wp-content/uploadsAndroid devices using responsive designs.

    Don’t Forget:

    Always test your Nginx configuration and then reload it. All changes to Nginx config must be followed with these commands:

    nginx -t && service nginx reload
    
Important Note:
    

    WP Super Cache caching will conflict with plugins that uses query vars. WooCommerce is an example known plugin known to work with above configuration. Reason is following line:
    

    try_files https://thinhcoi.com/wp-content/uploadswp-contenthttps://thinhcoi.com/wp-content/uploadscachehttps://thinhcoi.com/wp-content/uploadssupercachehttps://thinhcoi.com/wp-content/uploads$http_hosthttps://thinhcoi.com/wp-content/uploads$cache_urihttps://thinhcoi.com/wp-content/uploadsindex.html $uri $urihttps://thinhcoi.com/wp-content/uploads https://thinhcoi.com/wp-content/uploadsindex.php ;
    
It doesn’t passes $args to https://thinhcoi.com/wp-content/uploadsindex.php. If you set last try_files argument to https://thinhcoi.com/wp-content/uploadsindex.php?$args as with other WordPress-Nginx configuration, WP Super Cache, itself will break!

What are we going to build?
In this tutorial we will learn how we can facilitate user registration but letting users register to our site using their facebook accounts. This way, they won’t have to fill in any data, just grant the app access to their facebook account and that’s it! Their new account is created and they can easily login to our website.
