the_meta()

Displays a list of post custom fields.

More Information

This is a simple built-in function for displaying custom fields for the current post, known as the “post-meta” (stored in the wp_postmeta table). It formats the data into an unordered list (see output below).

It must be used from within The Loop or in a theme file that handles data from a single post (e.g. single.php). the_meta() will ignore meta_keys (i.e. field names) that begin with an underscore.

For more information on this tag, see Custom Fields.

Since revision 41583, the_meta() allow translators to manage spaces before the colon character.

Default output:

<ul class="post-meta">
    <li><span class='post-meta-key'>Your first meta key:</span> one or several values separated by commas</li>
    …
    <li><span class='post-meta-key'>Your second meta key:</span> one or several values separated by commas</li>
    <li><span class='post-meta-key'>Your third meta key:</span> one or several values separated by commas</li>
</ul>

French output:

<ul class="post-meta">
	<li><span class='post-meta-key'>Your first meta key :</span> one or several values separated by commas</li>
	…
	<li><span class='post-meta-key'>Your second meta key :</span> one or several values separated by commas</li>
	<li><span class='post-meta-key'>Your third meta key :</span> one or several values separated by commas</li>
</ul>

There is a non breaking space character before the colon character. Each Locale can handle it differently.
