Changes to blog/categories

I’ve just updated a site to use the new categories and blog version, but I’m having a slight issue. I’m adding classes to each blog post in the list and colouring them depending on the category. I previously got the category in post_in_list.html using:

<perch:blog id="categories" encode="false" />

But that doesn’t seem to work anymore, it previously returned the slug (as far as I can remember) but now it returns a number (which I assume is the id of the category).

I’ve tried various alternatives, but none work.

What do I need to change it to to work with the latest version?

Have you followed the update instructions?

Hello Drew,

yes I’ve followed the instructions which made the categories show when editing a blog post and shows the categories in the post itself, but the post_in_list.html template doesn’t work.

I’ve tried various things like:

<article class="hentry <perch:category id="catSlug" type="slug" />">

But I think I’m missing something obvious somewhere.

You need to use the <perch:categories> tags from your post.html template.

Here is my post.html template:

<article class="hentry">
    <perch:blog id="postTitle" type="text" label="Title" required="true" size="xl autowidth" order="1" suppress="true" />
    <h2 class="published">Published <perch:blog id="postDateTime" type="date" label="Date" time="true" format="%d %B %Y" divider-before="Meta information" /></h2>
    <img src="<perch:blog id="image" type="image" width="320" height="320" crop="true" label="Image" order="4" />" alt="<perch:blog id="postTitle" />" />
    <div class="description entry-content">
    <perch:blog id="postDescHTML" type="textarea" label="Post" order="2" editor="markitup" textile="true" size="xxl autowidth" required="true" />
  </div>
</article>

<perch:blog id="excerpt" type="textarea" label="Excerpt" textile="true" order="3" size="s" editor="markitup" suppress="true" />
<perch:blog id="image" type="image" width="500" height="500" suppress="true" />

<perch:categories id="categories" set="blog" label="Categories" display-as="checkboxes">
 <a href="archive.php?cat=<perch:category id="catSlug" type="slug" suppress="true" />">
    <perch:category id="catTitle" type="text" suppress="true" />
 </a>
</perch:categories>

and here is my post_in_list.html template:

<article class="hentry <perch:category id="catSlug" />">
    <header>
        <h2>
            <a href="<perch:blog id="postURL" type="hidden" />" rel="bookmark" class="entry-title">
        <perch:blog id="postTitle" type="text" label="Title" required="true" size="xl autowidth" order="1" />
      </a>
    </h2>
        <p class="published">published <perch:blog id="postDateTime" type="date" label="Date" time="true" format="%d %B %Y" divider-before="Meta information" /> </p>
    </header>
    <img src="<perch:blog id="image" type="image" width="320" height="320" crop="true" label="Image" order="4" />" alt="<perch:blog id="postTitle" />" />
    <div class="description entry-content">
    <perch:blog id="excerpt" textile="true" />
  </div>
</article>
<perch:after>
    <perch:if exists="paging">
        <div class="paging">
            Page <perch:blog id="current_page" /> of <perch:blog id="number_of_pages" />
            <perch:if exists="not_first_page">
                <a href="<perch:blog id="prev_url" encode="false" />">Previous</a>
            </perch:if>
            <perch:if exists="not_last_page">
                <a href="<perch:blog id="next_url" encode="false" />">Next</a>
            </perch:if>
        </div>
    </perch:if>
</perch:after>

If I take out suppress from the post.html template it shows the category with a link including the slug, but it doesn’t output the slug in post_in_list.html

So, in your list template, add your categories.

<perch:categories id="categories" set="blog">
 <a href="archive.php?cat=<perch:category id="catSlug" type="slug" />">
    <perch:category id="catTitle" type="text" />
 </a>
</perch:categories>

Thanks Drew,

it works perfectly now. I hadn’t realised it needed <perch:categories> everyone I wanted to use them, I thought it was just when setting categories, it does make sense now I think about it though.

Thanks again for all the help.
