Checkout field next to each other

I found that I should add a row class to the postcode and city to get this done.

I have this code:

function custom_override_checkout_fields( $fields ) {

$fields[‘city’] = array(
‘label’ => __(‘Town / City’, ‘woocommerce’),
‘placeholder’ => _x(‘Town / City’, ‘woocommerce’),
‘required’ => true,
‘class’ => array(‘form-row-first’)
),

$fields[‘postcode’] = array(
‘label’ => __(‘Postcode / Zip’, ‘woocommerce’),
‘placeholder’ => _x(‘Postcode / Zip’, ‘woocommerce’),
‘required’ => true,
‘class’ => array(‘form-row-last’);

return $fields;

}

I’ve put this in my functions.php but the site breaks. How do I get this working properly?

I also have the following code just above it

add_filter( ‘woocommerce_checkout_fields’ , ‘custom_override_checkout_fields’ );

function custom_override_checkout_fields( $fields ) {

unset($fields[‘billing’][‘billing_address_2’]);

unset($fields[‘billing’][‘billing_company’]);

unset($fields[‘shipping’][‘shipping_address_2’]);

unset($fields[‘shipping’][‘shipping_company’]);

}

I also found this code, I think this is actually what I should be using:

// Hook in
add_filter( 'woocommerce_default_address_fields' , 'custom_override_default_address_fields' );

// Our hooked in function - $address_fields is passed via the filter!
function custom_override_default_address_fields( $address_fields ) {
     $address_fields['address_1']['required'] = false;

     return $address_fields;
}

This is what I made of it, but it is not working. Can somebody correct me here?

// Hook in
add_filter( 'woocommerce_default_address_fields' , 'custom_override_default_address_fields' );

// Our hooked in function - $address_fields is passed via the filter!
function custom_override_default_address_fields( $address_fields ) {
     $address_fields['city']['class'] = array('form-row-first');
     $address_fields['postcode']['class'] = array('form-row-last');

     return $address_fields;
}

i have exactly the same problem. after reading the documentation i came up with the same code like you… but it doesn’t work

i also tried it with this code:

function custom_override_default_address_fields( $address_fields ) {
      $address_fields['postcode']  = array(
      'label'          => __('Postcode', 'woothemes'),
      'placeholder'    => __('Postcode', 'woothemes'),
      'required'       => false,
      'class'          => array('form-row-first'),
      'label_class'    => array('testing')
   	);  

	 return $address_fields;
}

it seems that everything works fine (like setting required to false, change the label name, label class, placeholder…) but NOT the class!?

maybe someone knows what could be wrong, thanks!
