WordPress child theme override index PHP

Generally, the homepage of the WordPress child theme is the same as the parent theme. But if you want to customize it then you have to modify the code in the index.php file of the parent theme. But first, import it to the child theme folder before modifying it.

What is a child theme?

A child theme is a WordPress theme that looks and feels the same as the main theme, commonly called the parent theme.

Why your child theme does not override the index page of the parent theme?

Your child theme does not override the index page of the parent theme because there is no index.php file in the child theme folder.

When you install a child theme, the index page or the homepage looks the same as that of the parent theme.

It is because installing the WordPress child theme does not replace the index.php page of the parent theme automatically.

Generally, a child theme has only two files in it – functions.php and style.css.

You can add your custom functions and styles in those two files.

It inherits all the functions, styles, and page templates of the parent theme.

As such, your site looks the same before and after installing a child theme.

What’s the use of a child theme then?

Well, by installing a child theme you ensure that custom functions and styles that you put in the functions.php and styles.css files in the child theme are not overwritten when the parent theme updates.

So, it is always recommended to use a child theme if you want to customize your WordPress theme by modifying the codes of those files.

And by the way, there is no WordPress override class in child theme.

How to create a child theme?

Is there a child theme WordPress plugin?

Yes, there is.

If your theme developer has not provided a child theme you can use a WordPress child theme generator plugin to generate one.

However, you can do it yourself too, without using any plugins.

Here’s how to create child theme in WordPress without plugin:

  • Create a new folder on your computer.
  • Name it as – [theme name] Child. Replace [theme name] with the name of your parent WordPress theme.
  • Inside the folder, create a text file and name it style.css.
  • Open the style.css file and write the following –
/* Theme Name: [theme name] Child

Theme URI: [URL of the theme’s site]

Description: Default [theme name] child theme

Author: [your name]

Author URI: [URL of your site]

Template: [theme name]

Version: 1.0.0 

*/ 

@import url("../Theme/style.css"); 

/* Write the path to main theme folder */
  • Save and close the file.
  • Now, zip the [theme name] Child folder.
  • Log in to WordPress.
  • Go to Appearance > Themes.
  • Click the Add New button.
  • Click the Upload Theme button.
  • Click Choose file and browse to the zipped [theme name] Child folder.
  • Click Install Now. The child theme will be listed under Themes. 
  • Click on Activate.

How to customize the index.php page in a child theme?

Here are the steps to customize the homepage after you have installed the child theme.

  • Log in to your site through FTP.
  • Go to the wp-content/themes/[Your Parent Theme] folder. [Your Parent theme] is the name of your parent theme.
  • In the parent theme folder find the index.php file. Please note that it may be named home.php.
  • Copy the file.
  • Go to wp-content/themes/[theme name] Child folder.
  • Paste the index.php file.
  • Log out.
  • Log in to WordPress.
  • Go to Appearance > Theme File Editor. 
  • Click the index.php file on the right under Theme Files.
  • Now edit the file as you per your need.
  • When you finish editing it, save your changes by clicking the Update File button.

The index.php file in your child theme will now override the index.php file of the parent theme.

You can also use this file as a template for any page on your site and select that page as the homepage of your site too.
