| //The given code is a WordPress function that modifies the breadcrumbs displayed on a website. Breadcrumbs are a navigation aid that helps users understand their current location within a website's hierarchy. | |
| // | |
| //The function "dgtlnk_breadcrumbs" takes an array of breadcrumb links as input and returns a modified version of the array. | |
| // | |
| //Here is a step-by-step explanation of the code: | |
| // | |
| //1. The function begins by accessing the global variable $post, which represents the current WordPress post or page being displayed. | |
| // | |
| //2. It then checks if the current page is a WooCommerce page by using the "is_woocommerce()" function. WooCommerce is a popular e-commerce plugin for WordPress. | |
| // | |
| //3. If the current page is a WooCommerce page, the function proceeds to add a new breadcrumb link to the array of links. | |
| // | |
| //4. The new breadcrumb link is an associative array with two elements: "url" and "text". The "url" element is set to the WooCommerce shop page URL, obtained using the "woocommerce_shop_page()" function. The "text" element is set to the string 'Shop'. | |
| // | |
| //5. The "array_splice()" function is used to modify the original array of breadcrumb links. It removes a portion of the array and replaces it with the newly added breadcrumb link. | |
| // | |
| //6. In this case, the "array_splice()" function is called with the following parameters: | |
| // - The original array of breadcrumb links ($links). | |
| // - The starting index for removal (1). | |
| // - The number of elements to remove (-2, meaning all elements except the first and last). | |
| // - The new breadcrumb link to insert ($breadcrumb). | |
| // | |
| //7. Finally, the modified array of breadcrumb links is returned by the function. | |
| // | |
| //8. The "add_filter()" function is used to register the "dgtlnk_breadcrumbs" function as a filter for the "wpseo_breadcrumb_links" hook. This means that whenever the breadcrumbs are generated, the "dgtlnk_breadcrumbs" function will be called to modify the breadcrumb links. | |
| function dgtlnk_breadcrumbs( $links ) { | |

| // | |
| //Inside the function, the global variable "$post" is used to check if the current page is a product category. If it is, a new breadcrumb link is added to the array "$breadcrumb" with a custom URL and text. | |
| // | |
| //The "array_splice" function is then used to replace a portion of the original breadcrumb links array with the new "$breadcrumb" array. The parameters for "array_splice" specify the starting index (0), the number of elements to remove (-1 to remove all elements except the last one), and the replacement array. | |
| // | |
| //Finally, the modified breadcrumb links array is returned. | |
| // | |

| //Then, the `array_splice()` function is used to insert the new breadcrumb link into the `$links` array. It replaces the elements starting from index 1 and ending 2 positions before the end of the array with the `$breadcrumb` array. | |
| // | |
| //Finally, the modified `$links` array is returned from the function. | |

| //6. The `array_splice` function is used to insert the `$breadcrumb` array into the `$links` array. It starts at index 1 (the second element) and removes all elements except the last two. Then it inserts the `$breadcrumb` array at that position. | |

| //1. The function `wpse_100012_override_yoast_breadcrumb_trail__second` is defined. | |
| //2. The `$links` parameter is passed to the function, which represents the existing breadcrumb trail links. | |
| //3. The global `$post` variable is accessed to check the current page. | |
| //4. The `is_home()` function is used to check if the current page is the home page. | |
| //5. The `is_singular( 'post' )` function is used to check if the current page is a single blog post page. | |
| //6. The `is_archive()` function is used to check if the current page is an archive page. | |
| //7. If any of the above conditions are true, the following code block is executed: | |
| // - An empty array `$breadcrumb` is created. | |
| //- An array element is added to `$breadcrumb` with the URL of the blog page and the text "Blog". | |
| //- The `get_option( 'page_for_posts' )` function is used to get the URL of the blog page. | |
| //- The `array_splice()` function is used to replace a portion of the `$links` array with the `$breadcrumb` array. The portion being replaced starts at index 1 and ends at the second-to-last index. | |
| //8. The modified `$links` array is returned. | |
| //9. The `wpse_100012_override_yoast_breadcrumb_trail__second` function is added as a filter to the `wpseo_breadcrumb_links` hook. This ensures that the function is called when the breadcrumb trail is generated by the Yoast SEO plugin. | |

| //The following code is a function called "override_yoast_breadcrumb_links" that modifies the Yoast SEO plugin's breadcrumb links. It checks if the current page is a singular post, and if so, it adds a new breadcrumb link to the array of links. This new link is for the "Blog" page and its URL is obtained using the "get_permalink" function with the ID of the page set as the "page_for_posts" option. | |
| // | |
| //The "array_splice" function is then used to replace a portion of the original breadcrumb links array with the newly added link. The parameters for "array_splice" specify that the replacement should start at index 1 (excluding the first link) and remove all elements except the last two. The new breadcrumb link is inserted at the position where the original portion was removed. | |
| // | |
| //Finally, the modified breadcrumb links array is returned by the function. | |
| // | |
| //The last line of code adds the "override_yoast_breadcrumb_links" function as a filter to the "wpseo_breadcrumb_links" hook, so that it is executed when the Yoast SEO plugin generates the breadcrumb links. | |
