WordPress breadcrumb solution without plugins

I won’t say much about the role of breadcrumb navigation. Anyway, each has its own purpose. I have shared the use of Yoast Breadcrumbs plug-in before. However, as wordpress takes up too much resources, if you can use less plug-ins, you can use plug-ins instead of plug-ins. Just now when Snail was organizing the website, he found this plug-in-free breadcrumb effect which is quite good. I recorded and organized it for future needs.

The first step is to add it to the Functions.php file

function get_breadcrumbs(){global $wp_query;

if ( !is_home() ){

// Start the ULecho \\\'

\\';// Add the Home linkecho \\\'
• Website homepage
\\';

if ( is_category() ){$catTitle = single_cat_title( \\”\\”, false );$cat = get_cat_ID( $catTitle );echo \\”

• » \\”. get_category_parents( $cat , TRUE, \\” » \\” ) .\\”
\\”;}elseif ( is_archive() && !is_category() ){echo \\”
• » Archives
\ \";}elseif ( is_search() ) {

echo \\”

• » Search Results
\\”;}elseif ( is_404() ){echo \\”
• » 404 Not Found
\\”;}elseif ( is_single() ){$category = get_the_category();$category_id = get_cat_ID( $category[0]->cat_name );

echo \\\'

• » \\'. get_category_parents( $category_id, TRUE, \\” » \\” );echo the_title(\\'\\',\\'\\', FALSE ) .\\”
\\”;}elseif ( is_page() ){$post = $wp_query->get_queried_object();

if ( $post->post_parent == 0 ){

echo \\”

• » \\”.the_title(\\’\\’,\\’\\’, FALSE).\\”
\\”;

} else {$title = the_title(\\'\\',\\'\\', FALSE);$ancestors = array_reverse( get_post_ancestors( $post->ID ) );array_push($ancestors, $post ->ID);

foreach ( $ancestors as $ancestor ){if( $ancestor != end($ancestors) ){echo \\\'

• » \\'. strip_tags( apply_filters( \\'single_post_title\\', get_the_title( $ancestor ) ) ) .\\\'
\\';} else {echo \\\'
• » \\'. strip_tags( apply_filters( \\'single_post_title\\', get_the_title( $ancestor ) ) ) .\\\'
\\';}}}}

// End the ULecho \\”

The second step is to add the breadcrumb plug-in at the appropriate location on the page where you need to add it

The third step, style definition

ul.breadcrumbs {list-style: none;padding: 0;margin: 0;font-size:12px;}ul.breadcrumbs li {float: left;margin: 0 5px 0 0;padding: 0;}< /p>

In summary, through the above three steps, you can achieve the breadcrumb effect without plug-ins, and the style and layout can be modified slightly.
