How should I include this PHP file?

    I created a file @ wp-content/plugins/echo-values.php

    Now I’m trying to figure out how to include that file. Just to test it, I’ve put the following code in the file:

    $MyCountry = ‘USA’;
    echo $MyCountry;

    I’ve been told that the plugins folder is the best place to put includes. I also read somewhere that any file placed in the plugins folder would “autoload.” But when I published the file online, I couldn’t find “USA” in the source code.

    So I apparently have to manually include the file. But what file should I insert the include in? I learned that wp-content/plugins/index.php is off limits.

    Also, I don’t know how to translate this…

    require_once(“/wp-content/plugins/echo-values.php”);

    to WordPress syntax. There are some examples @ https://codex.wordpress.org/Function_Reference/plugins_url but they’re very confusing. Can someone show me how to write a line of code including wp-content/plugins/echo-values.php?

    Thank you.

    If understand you, have you tried creating /mu-plugins/ directory and placing this echo-values.php inside it?

    Looks like this: /wp-content/plugins/mu-plugins/echo-values.php

    Actually, this turned into two problems, one of which I just solved. As you suggested, I created a new folder – mu-plugins – put my file inside it, and it does autoload.

    However, I still need to know how to write includes.

    The file inside my mu-plugins folder is fine for creating echo values, but if I want to actually display something at the beginning of an article or at the bottom of the page, then I need to be able to insert an include in the proper location.

    Also, I’m eventually going to put some database-driven reference tables on some of my pages, so I’ll have to include separate files that feature queries and a lot of styling, etc.

    Anyway, what’s the proper way to write an include?

    I don’t follow what you are trying to do. Perhaps someone else can chime in.

    You have so many choices; you could:

    1) create a simple shortcode that inserts php. That code could go into functions.php or in a plugin. See https://codex.wordpress.org/Shortcode_API. Gives you want the flexibility to put the code anywhere you like within post content.

    Or 2) put that code into one of your theme’s files. If you’re not using a child theme, please do so! Then that code could go within one or more of the template file in the child theme. Not as flexible as using a shortcode, but still a viable option.

    Or 3) put that code into a widget. Which makes sense if you’ll mainly want to place it within widgetised areas. http://www.wpbeginner.com/wp-tutorials/how-to-create-a-custom-wordpress-widget/

    Or 4) use a plugin such as https://wordpress.org/plugins/insert-php/ to insert PHP into any post.
