Hello !

I have some code that allow me to translate ACF instructions and lables with WP Globus :

add_filter( 'acf/get_valid_field', 'filter__wpglobus_get_valid_field' );
function filter__wpglobus_get_valid_field( $field ) {

	if ( ! class_exists( 'WPGlobus' ) ) {
		return $field;
	}

	if ( is_admin() ) {
		return $field;
	}

	$_fields[] = 'label';
	$_fields[] = 'instructions';
	

	foreach( $_fields as $_field ) {
		if ( ! empty( $field[ $_field ] ) ) {
			$field[ $_field ] = WPGlobus_Core::text_filter( $field[ $_field ], WPGlobus::Config()->language );
		}
	}
	

	return $field;
}

How can I modify my code in order to loop through the choices of my field to allow the translation of my choices ?

I also have a repeater field, but I cannot get access to the subfields.

Thank you for helping,

Marc

First, why are you using acf/get_valid_field, you can probably use acf/load_field and just do a check to make sure you’re not on the acf field group edit page. This would likely solve your problem with sub fields. https://www.advancedcustomfields.com/resources/acfload_field/

for the choices it would probably look something like

foreach ($field['choices'] as $value => $label)) {
  $field['choices'][$value] = WPGlobus_Core::text_filter($label, WPGlobus::Config()->language );
}

Hi John,

Thank you. I’ve tried the code in acf/load_field but, I receive an error message : Invalid argument supplied for foreach()

foreach ($field['choices'] as $value => $label) {
  $field['choices'][$value] = WPGlobus_Core::text_filter($label, WPGlobus::Config()->language );
}

any idea ?

I guess that depends on what type of field you’re trying to change the choice labels on. Since you are running this on every field you need to check that it’s a field type that actually has choices, or make sure that choices is set.

if (!empty($field['choices'])) {
  foreach ($field['choices'] as $value => $label) {
    $field['choices'][$value] = WPGlobus_Core::text_filter($label,   WPGlobus::Config()->language );
  }
}
