How To Change "Billing Details" Title On WooCommerce Checkout Page With A Hook

I am trying to change some titles on the WooCommerce checkout page.

One of the titles is "Billing details"

I've tried:

function wc_billing_field_strings( $translated_text, $text, $domain ) {
    switch ( $translated_text ) {
        case 'Billing details' :
            $translated_text = __( 'Billing Info', 'woocommerce' );
    return $translated_text;
add_filter( 'gettext', 'wc_billing_field_strings', 20, 3 );

I just can't change the text of those, whatever I add to my functions.php or WooCommerce alterations file.

Can you please let me know, how I can change those title?

Note: I would like to make use of action hooks. I don't won't to copy the WooCommerce template file as other options suggests.



Change switch ( $translated_text ) { with switch ( $text ) { in your code. This is because $text contains the original (undertranslated) text while $translated_text contains... the name of the variable already indicates it.

Or use

function filter_gettext( $translated, $original_text, $domain ) {   
    // Is admin
    if ( is_admin() ) return $translated;
    // No match
    if ( $original_text != 'Billing details' ) return $translated;
    // Match
    $translated = __( 'Billing Info', $domain );
    return $translated;
add_filter( 'gettext', 'filter_gettext', 10, 3 );
