    <p>I'm working on a customised wordpress widget which displays some social links if the widget text fields are completed:</p> <pre><code>if (!empty($fss_fb_icon) &amp;&amp; !empty($fss_fb_link) &amp;&amp; !empty($fss_fb_text)) { echo "nothing"; } else { echo "&lt;li class='social-new'&gt;&lt;img src='/images/social-media/16px/".$fss_fb_icon.".png' alt='".$fss_fb_text."'/&gt;&lt;a href='".$fss_fb_link."' target='_blank'&gt;".$fss_fb_text."&lt;/a&gt;&lt;/li&gt;"; } </code></pre> <p>Problem is this test always seems to return the else line of code, no matter the state of the widget's fields. I'm not certain if I've made a mistake in the php syntax or if there is some oddity of wordpress widgets I'm unaware of. Full code follows</p> <pre><code>class FSSSocialWidget extends WP_Widget { function FSSSocialWidget() { $widget_ops = array('classname' =&gt; 'FSSSocialWidget', 'description' =&gt; 'Displays social media links in the footer' ); $this-&gt;WP_Widget('FSSSocialWidget', 'FSS Social Media Footer', $widget_ops); } function form($instance) { $instance = wp_parse_args( (array) $instance, array( 'title' =&gt; '' ) ); $title = $instance['title']; $fss_fb_icon = $instance['fss_fb_icon']; $fss_fb_link = $instance['fss_fb_link']; $fss_fb_text = $instance['fss_fb_text']; ?&gt; &lt;p&gt;&lt;label for="&lt;?php echo $this-&gt;get_field_id('title'); ?&gt;"&gt;Title: &lt;input class="widefat" id="&lt;?php echo $this-&gt;get_field_id('title'); ?&gt;" name="&lt;?php echo $this-&gt;get_field_name('title'); ?&gt;" type="text" value="&lt;?php echo attribute_escape($title); ?&gt;" /&gt;&lt;/label&gt;&lt;/p&gt; &lt;p&gt;&lt;label for="&lt;?php echo $this-&gt;get_field_id('fss_fb_icon'); ?&gt;"&gt;Facebook Icon Name: &lt;input class="widefat" id="&lt;?php echo $this-&gt;get_field_id('fss_fb_icon'); ?&gt;" name="&lt;?php echo $this-&gt;get_field_name('fss_fb_icon'); ?&gt;" type="text" value="&lt;?php echo attribute_escape($fss_fb_icon); ?&gt;" /&gt;&lt;/label&gt;&lt;/p&gt; &lt;p&gt;&lt;label for="&lt;?php echo $this-&gt;get_field_id('fss_fb_link'); ?&gt;"&gt;Facebook URL: &lt;input class="widefat" id="&lt;?php echo $this-&gt;get_field_id('fss_fb_link'); ?&gt;" name="&lt;?php echo $this-&gt;get_field_name('fss_fb_link'); ?&gt;" type="text" value="&lt;?php echo attribute_escape($fss_fb_link); ?&gt;" /&gt;&lt;/label&gt;&lt;/p&gt; &lt;p&gt;&lt;label for="&lt;?php echo $this-&gt;get_field_id('fss_fb_text'); ?&gt;"&gt;Facebook Link Text: &lt;input class="widefat" id="&lt;?php echo $this-&gt;get_field_id('fss_fb_text'); ?&gt;" name="&lt;?php echo $this-&gt;get_field_name('fss_fb_text'); ?&gt;" type="text" value="&lt;?php echo attribute_escape($fss_fb_text); ?&gt;" /&gt;&lt;/label&gt;&lt;/p&gt; &lt;?php } function update($new_instance, $old_instance) { $instance = $old_instance; $instance['title'] = $new_instance['title']; $instance['fss_fb_icon'] = $new_instance['fss_fb_icon']; $instance['fss_fb_link'] = $new_instance['fss_fb_link']; $instance['fss_fb_text'] = $new_instance['fss_fb_text']; return $instance; } function widget($args, $instance) { extract($args, EXTR_SKIP); /* User-selected settings. */ $fss_fb_icon = $instance['fss_fb_icon']; $fss_fb_link = $instance['fss_fb_link']; $fss_fb_text = $instance['fss_fb_text']; echo $before_widget; $title = empty($instance['title']) ?

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.
