This plugin will work, “as is”, out of the box, but assumes some level of CSS and developer customization to adapt to your site’s specific needs.
Styles can be overridden via your theme’s style.css
Functionality can be overridden via your theme’s functions.php
”Examples”
Don’t display metabox on “product” post type:
<pre><code>add_filter( 'display_custom_fields', 'bb_no_product_metabox' ); function bb_no_product_metabox( $true, $post ) { if ( $post->post_type == 'product' ) return false; return true; } </code></pre>
Don’t display the product_id metakey
<pre><code>add_filter( 'dcf_postmeta', 'bb_no_product_id' ); function bb_no_product_id( $postmeta ) { unset( $postmeta['product_id'] ); return $postmeta; } </code></pre>
Don’t display metabox title
<pre><code>add_filter( 'dcf_heading', '__return_false' ); </code></pre>
Display metabox below content (rather than floated to the right)
<pre><code>add_filter( 'dcf_before_content', '__return_false' ); </code></pre>

Display Custom Fields

Inserts a Wikipedia-like metabox into posts with all the post's associated custom fields and taxonomy terms.

This plugin enables the use of [if] shortcodes to work with conditional logic based on the existence of post meta or taxonomy terms on posts and pages.
Please consider taking a minute to rate the plugin or let me know any feature request. Thanks!
<h4>Taxonomy</h4>
With conditional logic for taxonomy terms, you can use names, slugs or term_ids:
<ul>
<li>[if taxonomy=”category” slug=”cars”]Content to show[/if]</li>
<li>[if taxonomy=”category” name=”Cars”]Content to show[/if]</li>
<li>[if taxonomy=”category” id=”123″]Content to show[/if]</li>
</ul>
<h4>Post Meta</h4>
Post meta (or custom field) logic can be used to check if a certain meta_key AND meta_value combination are present or just a meta_key:
<ul>
<li>[if postmeta=”car_model”]Content to show if car model info is present[/if]</li>
<li>[if postmeta=”car_model” value=”Tesla Model S”]Content to show if car model is Tesla Model S[/if]</li>
</ul>

Logic Shortcodes

Use shortcodes for conditional logic based on post meta or taxonomy terms.
