The following WordPress Tutorial column will introduce to you how to solve the problem of manually adding custom code again after upgrading the WordPress theme. I hope it will be helpful to friends who need it. Helped!
Everyone who often messes with themes knows that adding code to the theme function template functions.php can increase the modification function, but it is troublesome to add these codes again after upgrading the theme. , here is a small method to avoid the trouble of repeated operations.
Some children may 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 might think, wow! I don’t know how to make a plug-in. It’s a bit complicated. It’s actually very simple. Create a new PHP file and add the following code to it:
<?php
/*
Plugin Name: 自定義模板函數(shù)
Plugin URI: https://zmingcx.com
Description: 免除升級(jí)主題手動(dòng)添加自定義代碼的煩惱
Author: 知更鳥
Version: 1.0
*/
// 將之前主題函數(shù)模板functions.php中的自定義代碼加在此行下面就可以了，比如在前端加一個(gè)提示對(duì)話框：
function plugins_tips() {
echo '<script>alert("您已成功制作了第一個(gè)WordPress插件！");</script>';
}
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.
