    <p>I'm trying to create a multidimensional array which stores a website navigation. Currently my navigation consists of Main -> Level 1 -> Level 2. I am having issues accessing level 2 correctly. </p> <p>My Array example array is...</p> <pre><code> $pages = array ( array('page_name' =&gt; 'Home'), array('page_name' =&gt; 'About us', 'level_one' =&gt; array('first1','first2', 'level_two' =&gt; array('second'), 'first3')), array('page_name' =&gt; 'Gallery', 'level_one' =&gt; array('first1','first2','first3','first4')), array('page_name' =&gt; 'Contact us') ); </code></pre> <p>My code to retrieve the navigation so far is...</p> <p>$count = count($pages);</p> <pre><code>for ($x=0; $x&lt;$count; $x++) { # echo yes for active page if ($filename == $pages[$x][1]) { echo 'yes'; } # echo main navigation echo $pages[$x]['page_name']; # check if the item has a sub page $firstcount = count($pages[$x]['level_one']); # if the item has a sub page echo if ($firstcount &gt; 0) { for ($y=0; $y&lt;$firstcount; $y++) { echo "\r\n" . '.' . $pages[$x]['level_one'][$y]; # check if the page has a sub page $secondcount = count($pages[$x]['level_one']['level_two']); if ($secondcount &gt; 0) { for ($z=0; $z&lt;$secondcount; $z++) { if($pages[$x]['level_one']['level_two'][$z] != '') { echo "\r\n" . '..' . $pages[$x]['level_one']['level_two'][$z]; } }} } } echo "\r\n"; } </code></pre> <p>And the output I'm currently getting is...</p> <pre><code>Home About us .first1 ..second .first2 ..second .first3 ..second . ..second Gallery .first1 .first2 .first3 .first4 Contact us </code></pre> <p>I am trying to create a multi level navigation. My expected output would be...</p> <pre><code>&lt;!-- Expected output Home About us .first1 .first2 ..second .first3 Gallery .first1 .first2 .first3 .first4 Contact us --&gt; </code></pre>

    1. COYou are more likely to get helpful feedback if you explain what output you are expecting -- what's wrong with the output you posted? Also, you have lots of expressions like `[first]` and `[name]`. These are not valid, unless you have called `define()` to declare these as constants; you should use single or double quotes like `['first']` or `["first"]`.

    2. CO@EdCottrell I'm pretty sure the reason it's not working is because of what you just described, i.e. the keys not being enclosed in quotation marks.

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.
