Give Theme Search Forms an Accessible Label
Adds an accessible name to the search field of theme search forms that have no label, so screen reader users hear "Search" instead of an unlabeled text field.
Opens WPIDE on
Code
// Accessible name for the search field.
$wpide_search_label = 'Search this site';
add_filter( 'get_search_form', function ( $form ) use ( $wpide_search_label ) {
if ( false !== stripos( $form, '<label' ) || ! class_exists( 'WP_HTML_Tag_Processor' ) ) {
return $form;
}
$tags = new WP_HTML_Tag_Processor( $form );
while ( $tags->next_tag( 'input' ) ) {
if ( ( 's' === $tags->get_attribute( 'name' ) || 'search' === $tags->get_attribute( 'type' ) ) && ! $tags->get_attribute( 'aria-label' ) ) {
$tags->set_attribute( 'aria-label', $wpide_search_label );
}
}
return $tags->get_updated_html();
}, 20 );Notes
Change $wpide_search_label to translate the label.
