Showing all posts for tag doesn't work

[Discostu36]

I try to create a tag list as described in the README. But it doesn't work completely.

What works so far:

• The tags are linked in my blog posts to the tag list
• The tag list shows all tags used on the blog
• For the first tag of each blog post, the tag list with url parameter does also work (e.g. ?tag=2000er)

What doesn't work

• For all other tags the blog post list is empty
• The tag list is not in alphabetical order (seems to have something to do with tags that are used more than one time)

tags.twig

The template for the task list has this code (slightly changed from the one in Readme)

{% set tag = url_param('tag', 'string') %}
{% set tags = get_all_tags() %}
{% if tag %}
    <h1>Tag: &nbsp;{{ tag }}</h1> 
    <p>Auf dieser Seite werden alle Artikel mit dem Tag <i>{{ tag }}</i> aufgeführt. <a href="{{current_page.url}}">Stattdessen alle Tags anzeigen</a>.
    {% for page in pages if page.title and tags and not (page.id ends with 'index') %}
        {% if page.meta.tags is iterable %}
            {% set pageTags = page.meta.tags %}
            {% set showTags = page.meta.tags|join(',') %}
        {% else %}
            {% set pageTags = page.meta.tags|split(',') %}
            {% set showTags = page.meta.tags %}
        {% endif %}
        {% if tag in pageTags %}
            <div class="post">
                    <h3><a href="{{ page.url }}">{{ page.title }}</a></h3>
                    <p class="date">{{ page.date_formatted }}</p>
                    <p class="excerpt">{{ page.description }}</p>
                </div>
        {% endif %}
    {% endfor %}
{% else %}
    <h1>Alle Tags</h1>
    <p>Hier werden alle Tags angezeigt, die auf <i>Freude am Film</i> benutzt werden.</p>
    <ul>
    {% for tag in tags %}
        <li><a href="{{current_page.url}}/?tag={{ tag }}">{{ tag }}</a></li>
    {% endfor %}
    </ul>
{% endif %}

blog_post.twig

This is what I have added to each blog post for linking:

{% if meta.tags %}  
    <p class="post-tags" >Tags:&nbsp;
        {% for tag in meta.tags %}  
        <a href="{{ base_url }}/tags?tag={{ tag|trim }}">{{ tag|trim }}</a>{% if not loop.last %},{% endif %}  
        {% endfor %}  
    </p>   
{% endif %}  

Rendered pages

For reference, here is the output:

• Blog post 1
• Blog post 2
• Complete tag list
• Tag list with parameter (first tag of blog post 1)
• Tag list with parameter (second tag of blog post 1) (doesn't work)

Hey!

Most likely, the issue is that the white-space around the tags isn't trimmed when looping through the pages in tags.twig. The example in the readme is perhaps a little sloppy. Try changing this part:

        {% if tag in pageTags %}
            <div class="post">
                    <h3><a href="{{ page.url }}">{{ page.title }}</a></h3>
                    <p class="date">{{ page.date_formatted }}</p>
                    <p class="excerpt">{{ page.description }}</p>
                </div>
        {% endif %}

to this:

        {% for pageTag in pageTags %}
                {% if pageTag|trim == tag %}
                    <div class="post">
                            <h3><a href="{{ page.url }}">{{ page.title }}</a></h3>
                            <p class="date">{{ page.date_formatted }}</p>
                            <p class="excerpt">{{ page.description }}</p>
                        </div>
                {% endif %}
        {% endfor %}

Let me know if that solves the issue for you, and I'll update the readme.

As for your second problem with the sorting, there's simply nothing that sorts the tags right now. You can do it in twig by e.g. changing {% for tag in tags %} to {% for tag in tags|sort %}.

Thank you very much, it now works well!
