Hence, you are strictly warned not to make any changes or edit any theme from the vendors directly. Only the most suitable way to edit or make changes in your theme is to create a child theme file or use WordPress Code snippets plugins.

To know how child theme works and how you can implement them to carry away update WordPress theme safely. Read our next section below:

Avoiding data loss by using a child theme

If you are not satisfied with the WordPress code snippet plugin, you can always go for a child theme. After all, it is one of the most effective methods used by professionals. But first, you must know what is a Child theme?

You can understand the child theme simply and most comprehensively as it works as a companion with your parent theme. It holds all the extra codes, features or code snippets that you want to make some necessary changes in your website design and its features, Without overwriting the existing codes in the parent theme.

Actually, you are providing a piece of additional information to WordPress, to update only the specific files that match with the same name of the parent theme files.

Let’s find out how it works?

If you are interested to know how things work inside a theme file and how WordPress updates without erasing any data in the parent theme, let us understand with a simple example.

For any theme , you will find three most common files present for showing archive pages, according to their Highest order they are:

  1. Category.php file
  2. Archive.php file
  3. Index.php file

WordPress follows the above hierarchy to display an archive and selects files whichever comes first. For example, if WordPress is showing a category archive, WordPress will choose the category.php file. But, if you are displaying a tag archive, WordPress will choose archive.php, it is because tag.php does not exist in the theme file.

However, when you create a Child theme and started to update the WordPress theme, WordPress will select the file with the higher order in the hierarchy list of the child theme, instead of the files in the parent theme.

To better understand this, let us suppose you created a child theme with an archive.php file, if your parent theme has a category.php file, WordPress will use the category.php file first from the parent theme itself. And if you are intended to use tags, WordPress will use archive.php file from the child theme instead of using from the parent. It is so because archive.php is in our 2nd position on the hierarchy list.

Hence, it is clearly shown that, if you want to make any customizations by adding code snippets or do some editing, you need to create a child theme first. Copy all the files from the parent theme to the child theme and make changes to it.

All the customizations or editing work will be done in child theme files without making any changes in the parent theme. Now, when you try to update the WordPress theme, the custom codes or any additional work you have done will not get wiped off. And instead of using the updated archive.php file of the parent theme, WordPress will use the archive.php file of the child theme.
