Body
<p>I have the following multidimensional array:</p> <pre><code><? $array = array(0 => 2, 3 => 1, 5 => 1 ); </code></pre> <p>Which looks like this when printed:</p> <pre><code>Array ( [0] => 2 [3] => 1 [5] => 1 ); //the value in brackets is the shoe size </code></pre> <p>The first part of array is a "shoe size", and the second part of the array is the number available in inventory.</p> <p>I am trying to print out a table that lists all shoe sizes (even if not in the array), and then loop through to provide "number available" in inventory.</p> <p>Here's what I have so far, but <strong>isn't working</strong>:</p> <pre><code><?php $array = array(0 => 2, 3 => 1, 5 => 1 ); print ('<table>'); print ('<thead><tr><th>Shoe Size</th>'); for ($i=3; $i<=12; $i += .50) { print ('<th>'.$i.'</th>'); } print('</tr></thead>'); print('<tbody><td>Total</td>'); foreach ($array as $shoe_size=>$number_in_inventory) { for ($i=3; $i<=12; $i += .50) { if ($i == $shoe_size) { print('<td>'.$number_in_inventory.'</td>'); } else { print('<td>0</td>'); } } } print("</tbody></table>"); </code></pre> <p>My problem is, because I have a <code>foreach</code> loop <strong>AND</strong> a <code>for</code> loop, it is printing out <strong>twice the number</strong> of table columns (<code><td></code>'s).</p> <p>How can I better adjust this code so that it only loops through and correctly displays the columns once? I am pretty lost on this one.</p> <p>Many thanks! </p>

Guidance

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.
