    <p>I'm am working on a Wordpress custom template and I'm filtering post by their classes. Since Wordpress displays a LOT of unnecessary classes when I put <code>&lt;?php post_class(); ?&gt;</code> in a page, <br/>( here is what it gives me <code>class="post-54 post type-post status-publish format-standard hentry category-3d category-web"</code> ) I'm trying to simplify that by echoing only the categories that relate to the post.</p> <p><br/> <strong>EDIT:</strong> <br/>This is what calls the post in my page <code>&lt;?php query_posts( 'showposts=99' ); ?&gt;</code></p> <p>Then this piece of code</p> <pre><code>&lt;li class="&lt;?php if ( in_category('category-3d')) { echo "3d"; } if ( in_category('category-animation')) { echo "animation"; } if ( in_category('category-motion')) { echo "motion"; } if ( in_category('category-shortfilm')) { echo "shortfilm"; }?&gt;"&gt;&lt;/li&gt; </code></pre> <p>give me this <code>&lt;li class="motion"&gt;&lt;/li&gt;</code> if my post is in the "motion" category.</p> <p>The problem is that <strong>if my post is in several categories, only the first is echoed</strong>... How can I tell WP to echo ALL the names of the categories my post is affected to, while adding a space between them?</p> <p>Since I am a beginner in php syntax, I'm still learning how to get such a simple thing working in a clean and effective way (i.e. without writing 16 lines of code !)... Can someone help me on this one? <br/><br/><br/> <strong>SECOND EDIT:</strong><br/> Ok I'm still trying to figure out why, but today, my piece of code (above) is working and echoes all my listed classes, but without space between them... So to make my classes work, I'm adding a space at the end of the echo part like this <code>{ echo "3d "; }</code>. But I feel like it's a dirty way to make things work... <br/><br/> <strong>How to add a space between each class tag in the proper way?</strong> I'm aiming for something like this <code>foreach $categories as $cat { echo $cat . " "; }</code> but where $categories and $cat would refer to each "if" statement.</p>

    1. CO`3d` isn't a valid class name. Prefix your classes with something like `category-`.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
