Replace a label on WooCommerce checkout

function modify_state_county_label( $translated_text, $text, $domain ) {
    switch ( $translated_text ) {
        case 'State/County' :
            $translated_text = __( 'County', 'woocommerce' );
            break;
    }
    return $translated_text;
}
add_filter( 'gettext', 'modify_state_county_label', 20, 3 );

The modify_state_county_label function customizes the text displayed on a WooCommerce site, specifically targeting the “State/County” label. Here’s a breakdown of what it does and how it works:

Function Explanation

  1. Parameters:
    • $translated_text: The text that has already been translated and will be displayed.
    • $text: The original text before translation.
    • $domain: The text domain, used to identify the source of the translation (e.g., woocommerce in this case).
  2. Switch Statement:
    • The function checks if the $translated_text matches the string 'State/County'.
    • If it does, the label is changed to 'County' using the __() function, which retrieves the translation for the specified string within the WooCommerce text domain ('woocommerce').
  3. Return Value:
    • After potentially modifying the $translated_text, the function returns it.

Hook: add_filter

The add_filter function is used to attach modify_state_county_label to the gettext filter.

  • gettext: This is a WordPress filter hook that allows you to modify any text string after it has been translated.
  • 'modify_state_county_label': The custom function to run when the gettext filter is applied.
  • 20: The priority of this filter. A higher number means this filter runs later, allowing other filters with lower priority to execute first.
  • 3: The number of arguments that the function expects to receive ($translated_text, $text, $domain).

Purpose

This function is useful for customizing the labels in WooCommerce forms or any other text strings displayed on the site. By default, WooCommerce may use “State/County” as a label in address forms. This function replaces that with “County,” making the form more relevant for regions where “County” is the preferred term.

Usage

Add this code to your theme’s functions.php file or a custom plugin. After adding it, the “State/County” label in WooCommerce will be replaced by “County.”

This is particularly useful for regions like Ireland or the UK, where “State” might not be applicable.
