Breadcrumbs are navigation links that are used by all the sites by which user can understand the hierarchy of the pages. Breadcrumbs are used to display all the pages links leading from the homepage.

  In WordPress, breadcrumbs plays an important role on the posts . There are many wordpress plugins available by which you can show the breadcrumbs easily but we recommend you not to use any plugin and to use simple code to display breadcrumbs on your WordPress website. 

Create Breadcrumbs:

First for creating Breadcrumbs, we have to make a function named get_breadcrumb() to generate the breadcrumb links.(you can make the function of any name) You only need to add the get_breadcrumb() function code in functions.php file in your wordpress theme you are using.

function get_breadcrumb() {    // breadcrumb function
    echo '<a href="'.home_url().'" rel="nofollow">Home</a>'; //link to the homepage
    if (is_category() || is_single()) {
        echo "&nbsp;&nbsp;&#187;&nbsp;&nbsp;";
        the_category(' &bull; ');
            if (is_single()) {
                echo " &nbsp;&nbsp;&#187;&nbsp;&nbsp; ";
                the_title();
            }
    } elseif (is_page()) {
        echo "&nbsp;&nbsp;&#187;&nbsp;&nbsp;";
        echo the_title();
    } elseif (is_search()) {
        echo "&nbsp;&nbsp;&#187;&nbsp;&nbsp;Search Results for... ";
        echo '"<em>';
        echo the_search_query();
        echo '</em>"';
    }
}

Display Breadcrumbs:

Call the get_breadcrumb() function in single.php or page.php file of your WordPress theme.

<div class="breadcrumb"><?php get_breadcrumb(); ?></div>
