Question about breadcrumb links

Question

I am using Craft only for the blog section of my HTML site. I have integrated my existing breadcrumbs to the blog, but there is a problem.

When I am on the home page of the blog, the word "Blog" in the breadcrumb is linked, and I would rather it not be linked.

I would like the word "Blog" in the breadcrumb to be a link only after going to an article on the blog. Please see attached.

The code I am using right now is

    <ol class="breadcrumb">
        <li><a href="/index.html">Home</a></li>
            <li><a href="{{ siteUrl }}">Blog</a></li>
            {% for crumb in entry.getAncestors() %}
                <li>{{ crumb.getLink() }}</li>
            {% endfor %}
            <li>{{ entry.title() }}</li>
    </ol>

I am new to Craft - thanks for your help!

Answer 1

A conditional that keys off the presence of the second segment to determine what to show for the "Blog" link/copy will work.

{% set seg2 = "" %}
{% set seg2 = craft.request.getSegment(2) %}

<ol class="breadcrumb">
    <li><a href="/">Home</a></li>
    <li>
        {% if seg2 == "" %}
            Blog
        {% else %}
            <a href="{{ siteUrl }}">Blog</a>
        {% endif %}
    </li>
    {% for crumb in entry.getAncestors() %}
        <li>{{ crumb.getLink() }}</li>
    {% endfor %}
    <li>{{ entry.title() }}</li>
</ol>

Answer 2

First, if your Blog section type is a Channel and not a Structure, then {% for crumb in entry.getAncestors() %} won't return anything. Your entry needs to be in a structure have any ancestors.

Here's a rundown of Craft's section types:

http://buildwithcraft.com/docs/sections-and-entries

This is really going to depend on how you have your templates and sections are setup, but here's how a basic setup for a Blog channel might work.

Let's say you have a Blog section that's a Channel section type. In your craft/templates folder, you have the following folders:

blog/
blog/index.html
blog/_entry.html

In the settings for the Blog section, you have...

Entry URL Format: blog/{slug}

Entry Template: blog/_entry

If you're on an entry page like example.com/blog/what-makes-a-good-logo-design, Craft will route to the blog/_entry.html template. In that file your breadcrumb could be just this:

<ol class="breadcrumb">
    <li><a href="{{ siteUrl }}">Home</a></li>
    <li><a href="/blog">Blog</a></li>
    <li>{{ entry.title }}</li>
</ol>

If you go to example.com/blog, Craft will route to the blog/index.html template. In that file, you can have a separate breadcrumb like this:

<ol class="breadcrumb">
    <li><a href="{{ siteUrl }}">Home</a></li>
    <li>Blog</li>
</ol>
