How To Link Post Thumbnail To The Post Permalink

Are you looking for a way to link your Post Thumbnail to Post Permalink? Then, this guide is a definite for you. The issue came when I was looking for a way to show the thumbnail with post permalink. And I found a solution on WordPress but it was not satisfying me. So I tried the below-given code to the functions.php of  WordPress theme and It automatically linked all post thumbnails to the post permalink.

add_filter( 'post_thumbnail_html', 'wps_post_thumbnail', 10, 3 );
function wps_post_thumbnail( $html, $post_id, $post_image_id ) {
  $html = '<a href="' . get_permalink( $post_id ) . '" title="' . esc_attr( get_post_field( 'post_title', $post_id ) ) . '">' . $html . '</a>';
  return $html;
}

You probably shouldn’t add links unless the thumbnail exists, so here is a way to do that:

<?php
if ( has_post_thumbnail()) {
  echo '<a href="' . get_permalink($post->ID) . '" >';
  the_post_thumbnail( 'title-image', array( 'class' => 'title-image', 'alt' => 'Title Icon' );
  echo '</a>';
}
?>
