    <p>I'm having a bit of trouble trying to get my head around some php code. To explain:</p> <p>I have a navbar made from bootstrap. I want this nav bar to change it's active class depending on the page. I have a subnav within the navbar with an li class of 'dropdown'. When this page is active this li class wants to change to 'dropdown active' When other pages are active, they just want a simple class of 'active'.</p> <p>My code is as follows: PHP:</p> <pre><code> $pageLoc = 'where'; $nav_items = array('index'=&gt;'Home', 'where'=&gt;'Where?', 'appeals'=&gt;'Current Appeals', 'news'=&gt;'Latest News', 'events'=&gt;'Events', 'dontate'=&gt;'Dontate', ); $nav_sub = array('africa'=&gt;'Africa', 'bangladesh'=&gt;'Bangladesh', 'gaza'=&gt;'Palestine/Gaza', 'kashmir'=&gt;'Kashmir', 'pakistan'=&gt;'Pakistan', 'uk'=&gt;'United Kingdom' ); foreach ($nav_items as $nav_href=&gt;$nav_title) { if ($pageLoc == $nav_href) &amp;&amp; ($pageLoc == 'where') { echo '&lt;li class="dropdown active"&gt;' . $nav_title . '&lt;/li&gt;'; } elseif ($pageHref == $nav_href) &amp;&amp; ($pageLoc == 'no') { echo '&lt;li class="dropdown"&gt;' . $nav_title . '&lt;/li&gt;'; } elseif ($pageHref == $nav_href) { echo '&lt;li class="active"&gt;' . $nav_title . '&lt;/li&gt;'; } else { echo '&lt;li&gt;' . $nav_title . '&lt;/li&gt;'; } } </code></pre> <p>Navbar:</p> <pre><code>&lt;ul class="nav pull-right"&gt; &lt;li class="pull-right"&gt; &lt;a class="btn-danger" href="donate"&gt;&lt;i class="icon-medkit"&gt; DONATE!&lt;/i&gt;&lt;/a&gt; &lt;/li&gt; &lt;/ul&gt; &lt;ul class="nav pull-right"&gt; &lt;li class=""&gt; &lt;a href="../"&gt;Home&lt;/a&gt; &lt;/li&gt; &lt;li class="dropdown"&gt; &lt;a href="../where/" class="dropdown-toggle disabled" data-toggle="dropdown"&gt; Where? &lt;b class="caret"&gt;&lt;/b&gt; &lt;/a&gt; &lt;ul class="dropdown-menu"&gt; &lt;li class="nav-header"&gt;Where we operate&lt;/li&gt; &lt;li class="divider"&gt;&lt;/li&gt; &lt;li&gt;&lt;a href="../where/africa"&gt;Africa&lt;/a&gt;&lt;/li&gt; &lt;li&gt;&lt;a href="../where/bangladesh"&gt;Bangladesh&lt;/a&gt;&lt;/li&gt; &lt;li&gt;&lt;a href="../where/palestine-gaza"&gt;Palestine/Gaza&lt;/a&gt;&lt;/li&gt; &lt;li&gt;&lt;a href="../where/kashmir"&gt;Kashmir&lt;/a&gt;&lt;/li&gt; &lt;li&gt;&lt;a href="../where/pakistan"&gt;Pakistan&lt;/a&gt;&lt;/li&gt; &lt;/ul&gt; &lt;/li&gt; &lt;li class=""&gt; &lt;a href="../appeals"&gt;Current Appeals&lt;/a&gt; &lt;/li&gt; &lt;li class=""&gt; &lt;a href="../news"&gt;Latest News&lt;/a&gt; &lt;/li&gt; &lt;li class=""&gt; &lt;a href="../events"&gt;Events&lt;/a&gt; &lt;/li&gt; &lt;/ul&gt; </code></pre> <p>I am aware that this php is generating a syntax error. I am no pro unfortunately! :( This is </p> <pre><code>what I originally had: foreach ($nav_items as $nav_href=&gt;$nav_title) { if ($pageHref == $nav_href) { echo '&lt;li class="active"&gt;' . $nav_title . '&lt;/li&gt;'; } else { echo '&lt;li&gt;' . $nav_title . '&lt;/li&gt;'; } } </code></pre>

    1. COI would start with opening the tags outside of the `if` sections and add the correct classes as your conditions are met. That would simplify things and make it easier to spot the mistake.

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.
