Highlight the search terms in results in WordPress

Highlight the search terms in results in WordPress

Use this code in theme’s function.php, and use search_excerpt_highlight() instead of the_excerpt() from where the search result coming.

function search_excerpt_highlight() {
$excerpt = get_the_excerpt();
$keys = implode('|', explode(' ', get_search_query()));
$excerpt = preg_replace('/(' . $keys .')/iu', '<span class="search-highlight"></span>', $excerpt);
echo '<p>' . $excerpt . '</p>';
}
and use this in CSS file or customize your style.

.search-highlight{
font-weight:bold;
}

But this can break you read-more link, if the search term exists in that.

So please use this code:

function search_excerpt_highlight() {
    $excerpt = get_the_excerpt();
    $keys = implode('|', explode(' ', get_search_query()));
    $excerpt = preg_replace('/(' . $keys .')/iu', '<span></span>', $excerpt);
    echo '<p>' . $excerpt . '&hellip;' . supralegal_read_more_link() . '</p>';
}

function supralegal_auto_excerpt_more( $more ) {
    return '';
}
add_filter( 'excerpt_more', 'supralegal_auto_excerpt_more' );

function supralegal_read_more_link() {
    return ' <a href="'. esc_url( get_permalink() ) . '">' . __( 'Read more', 'supralegal' ) . '</a>';
}

in supralegal_read_more_link() function write your read-more link code.
