如何在Wordpress中动态生成面包屑架构(所有页面，子页面，自定义帖子类型和分类)

Question

<script type="application/ld+json">
{
"@context": "https://schema.org",
"@type": "BreadcrumbList",
"itemListElement": [{
"@type": "ListItem",
"position": 1,
"name": "Home",
"item": "https://example.com/"
},{
"@type": "ListItem",
"position": 2,
"name": "<?php the_title(); ?>",
"item": "<?php the_permalink(); ?>"
}
]
}

我使用这个代码动态面包屑架构，但它只工作第一级页面和默认的帖子，我需要工作所有自定义帖子类型和自定义分类法。你能帮帮我吗?

Answer 1

试试这个脚本

<script>
var bread = {
"@@context": "https://www.schema.org",
"@@type": "BreadcrumbList",
"itemListElement": []
}
var exist = false;
$('.breadcrumb li').each(function (index) {
var item = {}
var href = $(this).find("a").attr('href');
if (href) item["@@id"] = "@Repository.Settings["WebSiteAddress"]" + href // OR location.protocol+"//"+location.host+href;
else item["@@id"] = "@Repository.Settings["WebSiteAddress"]" + window.location.pathname
item["name"] = $.trim($(this).text());
bread.itemListElement.push({
"@@type": "ListItem",
"position": index + 1,
item
})
exist = true;
});
if(exist){
var jsonStrb = JSON.stringify(bread);
var s2 = document.createElement("script");
s2.type = "application/ld+json";
s2.id = "BreadcrumbJson";
$("body").append(s2);
$('#BreadcrumbJson').append(jsonStrb);
}        </script>

<?php
// This function will take $_SERVER['REQUEST_URI'] and build a breadcrumb based on the user's current path
function breadcrumbs($separator = ' &raquo; ', $home = 'Home') {
// This gets the REQUEST_URI (/path/to/file.php), splits the string (using '/') into an array, and then filters out any empty values
$path = array_filter(explode('/', parse_url($_SERVER['REQUEST_URI'], PHP_URL_PATH)));
// This will build our "base URL" ... Also accounts for HTTPS :)
$base = ($_SERVER['HTTPS'] ? 'https' : 'http') . '://' . $_SERVER['HTTP_HOST'] . '/';
// Initialize a temporary array with our breadcrumbs. (starting with our home page, which I'm assuming will be the base URL)
$breadcrumbs = Array("<a href="$base">$home</a>");
// Find out the index for the last value in our path array
$last = end(array_keys($path));
// Build the rest of the breadcrumbs
foreach ($path AS $x => $crumb) {
// Our "title" is the text that will be displayed (strip out .php and turn '_' into a space)
$title = ucwords(str_replace(Array('.php', '_'), Array('', ' '), $crumb));
// If we are not on the last index, then display an <a> tag
if ($x != $last)
$breadcrumbs[] = "<a href="$base$crumb">$title</a>";
// Otherwise, just display the title (minus)
else
$breadcrumbs[] = $title;
}
// Build our temporary array (pieces of bread) into one big string :)
return implode($separator, $breadcrumbs);
}
?>
