Allowing link in a excerpt very common issue for WordPress users.
You can display excerpt link by adding this script to your theme “functions.php” file.
remove_filter( 'the_excerpt', 'wp_trim_excerpt' );
function new_trim_excerpt($text) {
global $post;
if ( '' == $text ) {
$text = get_the_content('');
$text = apply_filters('the_content', $text);
$text = str_replace('\]\]\>', ']]>', $text);
$text = preg_replace('@<script[^>]*?>.*?</script>@si', '', $text);
$text = strip_tags($text, '<a>');
$excerpt_length = 50;
$words = explode(' ', $text, $excerpt_length + 1);
if (count($words)> $excerpt_length) {
array_pop($words);
array_push($words, '...');
$text = implode(' ', $words);
}
}
return $text;
}
remove_filter('get_the_excerpt', 'wp_trim_excerpt');
add_filter('get_the_excerpt', 'new_trim_excerpt');
