How to avoid manually adding custom code again after upgrading your WordPress theme

Friends who often mess with themes know that adding code to the theme function template functions.php can increase the modification function. However, it is troublesome to add these codes again after upgrading the theme. Here is a small method to avoid repeated operations. troubles.

Save the trouble of manually adding custom code again after upgrading your WordPress theme

Some friends will think of making a sub-theme and adding custom code. The method in this article is much simpler than making a sub-theme.

The principle is to make a plug-in yourself, add custom code to it and enable it.

You may think that making a plug-in is a bit complicated, but it is actually very simple. Create a new PHP file and add the following code to it:

alert("You have successfully created your first WordPress plug-in!");'; } add_action( 'wp_footer', 'plugins_tips' );

When saving the file, you need to save the encoding as UTF-8 without BOM (no signature), otherwise garbled characters will be displayed. Then upload it to the wp-content/plugins plug-in directory and enable it on the WP background plug-in page.

Refreshing the front-end page will display a prompt dialog box, indicating that your first plug-in has been successfully created.

Making custom code into a plug-in has the same effect as adding it to the theme function template functions.php, once and for all.
