    <p>Anyone?</p> <p>Thanks in advance, and let me know if you need any additional info.</p> <p>I am attempting to turn a multi dimensional array to a multiple nested html navigation menu. I have the jist of it from another answer on SO: <a href="https://stackoverflow.com/questions/8685825/php-loop-through-multidimensional-array-and-establish-parent-child-relationship">solution here</a>.</p> <p>What I am trying to figure out is how to preserve the top level parent link (and any subsequent child page links) in the url for the next child array. I tried passing in the link to the function when it calls itself to build the array, but that only preserved the most recent parent link.</p> <p>Example:</p> <p>Home About<br> -Info<br> --Sub Page</p> <p>becomes:</p> <p>home about about/info about/info/subpage</p> <p>Here is a sample array:</p> <pre><code>Array ( [0] =&gt; stdClass Object ( [id] =&gt; 12 [parent] =&gt; 11 [name] =&gt; Sub Page [link] =&gt; sub_page [target] =&gt; _self ) [1] =&gt; stdClass Object ( [id] =&gt; 14 [parent] =&gt; 12 [name] =&gt; Test [link] =&gt; test_test [target] =&gt; _self ) [2] =&gt; stdClass Object ( [id] =&gt; 9 [parent] =&gt; 0 [name] =&gt; Home [link] =&gt; home [target] =&gt; _self ) [3] =&gt; stdClass Object ( [id] =&gt; 11 [parent] =&gt; 10 [name] =&gt; Info [link] =&gt; info [target] =&gt; _self ) [4] =&gt; stdClass Object ( [id] =&gt; 13 [parent] =&gt; 10 [name] =&gt; Test [link] =&gt; test [target] =&gt; _self ) [5] =&gt; stdClass Object ( [id] =&gt; 10 [parent] =&gt; 0 [name] =&gt; About [link] =&gt; about [target] =&gt; _self ) </code></pre> <p>)</p> <p>And here is the code I am using:</p> <pre><code>function create_menu_array($arr, $parent = 0){ $pages = array(); foreach($arr as $page){ if($page-&gt;parent == $parent){ $page-&gt;sub = isset($page-&gt;sub) ? $page-&gt;sub : $this-&gt;create_menu_array($arr, $page-&gt;id); $pages[] = $page; } } return $pages; } function create_menu_html($nav){ $html = ''; foreach($nav as $page){ $html .= '&lt;ul&gt;&lt;li&gt;'; $html .= '&lt;a href="' . base_url().$page-&gt;link . '" target="'.$page-&gt;target.'"&gt;' . $page-&gt;name . '&lt;/a&gt;'; $html .= $this-&gt;create_menu_html($page-&gt;sub); $html .= '&lt;/li&gt;&lt;/ul&gt;'; } return $html; } </code></pre>

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.
