Breadcrumbs are important part of our websites. Most of the wordpress website are having breadcrumbs now a days. So, there are so many plugins available for the addition of breadcrumbs over the web.

But in my views addition of more and more plugins to the website will definitely affect the speed of the website. So, in spite of adding plugin for each small task we need to do some custom work in a easy way to make our website light with good speed.

I am sharing a custom code which will add breadcrumbs to the website in a very easy manner. Just add the below mentioned code in your function.php file : 

<?php 
function wptricks_custom_breadcrumbs() {
  $home_breadcrumbs = 0; // put 1 to show breadcrumbs on home page, otherwise leave it as it is
  $separator = '&raquo;'; // separator
  $home = 'Home'; // home text
  $mycurrent = 1; //put 1 to show current post/page title in breadcrumbs, otherwise leave put 0
  global $post;
  $myhome_url = get_bloginfo('url');
  if (is_home() || is_front_page()) {
    if ($home_breadcrumbs == 1) echo '<div id="crumbs"><a href="' . $myhome_url . '">' . $home . '</a></div>';
  } else {
    echo '<div id="crumbs"><a href="' . $myhome_url . '">' . $home . '</a> ' . $separator . ' ';
    if ( is_category() ) {
      $thisCat = get_category(get_query_var('cat'), false);
      if ($thisCat->parent != 0) echo get_category_parents($thisCat->parent, TRUE, ' ' . $separator . ' ');
      echo '<span>' . 'Archive :"' . single_cat_title('', false) . '"' . '</span>';
    } elseif ( is_search() ) {
      echo '<span>' . 'Results :"' . get_search_query() . '"' . '</span>';
    } elseif ( is_day() ) {
      echo '<a href="' . get_year_link(get_the_time('Y')) . '">' . get_the_time('Y') . '</a> ' . $separator . ' ';
      echo '<a href="' . get_month_link(get_the_time('Y'),get_the_time('m')) . '">' . get_the_time('F') . '</a> ' . $separator . ' ';
      echo '<span>' . get_the_time('d') . '</span>';
    } elseif ( is_month() ) {
      echo '<a href="' . get_year_link(get_the_time('Y')) . '">' . get_the_time('Y') . '</a> ' . $separator . ' ';
      echo '<span>' . get_the_time('F') . '</span>';
    } elseif ( is_year() ) {
      echo '<span>' . get_the_time('Y') . '</span>';
    } elseif ( is_single() && !is_attachment() ) {
      if ( get_post_type() != 'post' ) {
        $post_type = get_post_type_object(get_post_type());
        $slug = $post_type->rewrite;
        echo '<a href="' . $myhome_url . '/' . $slug['slug'] . '/">' . $post_type->labels->singular_name . '</a>';
        if ($mycurrent == 1) echo ' ' . $separator . ' ' . '<span>' . get_the_title() . '</span>';
      } else {
        $cat = get_the_category(); $cat = $cat[0];
        $cats = get_category_parents($cat, TRUE, ' ' . $separator . ' ');
        if ($mycurrent == 0) $cats = preg_replace("#^(.+)\s$separator\s$#", "$1", $cats);
        echo $cats;
        if ($mycurrent == 1) echo '<span>' . get_the_title() . '</span>';
      }
    } elseif ( !is_single() && !is_page() && get_post_type() != 'post' && !is_404() ) {
      $post_type = get_post_type_object(get_post_type());
      echo '<span>' . $post_type->labels->singular_name . '</span>';
    } elseif ( is_attachment() ) {
      $parent = get_post($post->post_parent);
      $cat = get_the_category($parent->ID); $cat = $cat[0];
      echo get_category_parents($cat, TRUE, ' ' . $separator . ' ');
      echo '<a href="' . get_permalink($parent) . '">' . $parent->post_title . '</a>';
      if ($mycurrent == 1) echo ' ' . $separator . ' ' . '<span>' . get_the_title() . '</span>';
    } elseif ( is_page() && !$post->post_parent ) {
      if ($mycurrent == 1) echo '<span>' . get_the_title() . '</span>';
    } elseif ( is_page() && $post->post_parent ) {
      $parent_id  = $post->post_parent;
      $breadcrumbs = array();
      while ($parent_id) {
        $page = get_page($parent_id);
        $breadcrumbs[] = '<a href="' . get_permalink($page->ID) . '">' . get_the_title($page->ID) . '</a>';
        $parent_id  = $page->post_parent;
      }
      $breadcrumbs = array_reverse($breadcrumbs);
      for ($i = 0; $i < count($breadcrumbs); $i++) {
        echo $breadcrumbs[$i];
        if ($i != count($breadcrumbs)-1) echo ' ' . $separator . ' ';
      }
      if ($mycurrent == 1) echo ' ' . $separator . ' ' . '<span>' . get_the_title() . '</span>';
    } elseif ( is_tag() ) {
      echo '<span>' . 'Posts tagged "' . single_tag_title('', false) . '"' . '</span>';
    } elseif ( is_author() ) {
       global $author;
      $userdata = get_userdata($author);
      echo '<span>' . 'Articles By ' . $userdata->display_name . '</span>';
    } elseif ( is_404() ) {
      echo '<span>' . '404' . '</span>';
    }
    if ( get_query_var('paged') ) {
      if ( is_category() || is_day() || is_month() || is_year() || is_search() || is_tag() || is_author() ) echo ' (';
      echo __('Page') . ' ' . get_query_var('paged');
      if ( is_category() || is_day() || is_month() || is_year() || is_search() || is_tag() || is_author() ) echo ')';
    }
    echo '</div>';
  }
}
?>

After this just put the below mentioned code where you want to show the breadcrumbs. Generally we will use it in our header.php files : 

<?php if (function_exists('wptricks_custom_breadcrumbs')){ wptricks_custom_breadcrumbs(); }?>
