Creating Child Theme

What is a child theme?

A child theme is a theme that can edit codes and styles from parent theme directly. Changes in child theme will remain after theme update while parent theme’s changes are removed. It is a good idea to use child theme if you are facing problems that can not be solved with theme’s providing options or styles. You could change core codes using template file modifications or hooks. Visit Child Theme for more details.

How to modify codes using child theme?

Theme are several ways to modify core codes.

1. Copy template files from parent theme

You could copy theme template files ( located in riode/template_parts directory ) or WooCommerce plugin’s template files ( located in woocommerce directory ) to child theme’s directory and modify them. You could copy only limited files for modification. If you copy and modify the other files except template files, changes will not affect to your site.

IMPORTANT NOTE:
Sometimes Riode theme and WooCommerce plugin will make major changes to these files. You should keep an eye on updates and if the, copy and modify them again.

2. Override function

You could change pre-defined functions by redefining them in child theme. You could probably see some functions wrapped with ‘function_exists’. And for these functions, you can do modifications. Child theme functions are loaded ahead of others, so you could create the same function in child theme and make changes to the content.

Below is the example of overriding functions. Let’s assume that you are going to modify ‘riode_get_col_class’ function. The original code ( this is from parent theme ) is like belows.

/* This is original code */
if ( ! function_exists( 'riode_get_col_class' ) ) {
function riode_get_col_class( $col_cnt = array() ) {
$class = ' row';
foreach ( $col_cnt as $w => $c ) {
if ( $c > 0 ) {
$class .= ' cols-' . ( 'min' != $w ? $w . '-' : '' ) . $c;
}
}
return $class;
}
}

Now you can copy this function in child theme and make changes to the content. 

/* This is modification code */
function riode_get_col_class( $col_cnt = array() ) {
// your code here
...
...
...
}
3. Using hooks

Riode and other plugins provide many hooks ( including actions and filters ) for developers to modify core codes. You could add your codes to existing actions and filters.

/* Example of using hooks */
add_action( 'riode_wc_after_notice', 'riode_wc_notice_close', 10, 2 );
function riode_wc_notice_close() {
echo '<button type="button" class="btn btn-link btn-close"><i class="close-icon"></i></button>';
}
