    <p>I have a page that pulls 5 random rows from a table. It looks similar to the below.</p> <pre><code>&lt;table&gt; &lt;tr&gt; &lt;td&gt;&lt;input type = 'radio' name='bills[1]' value = 'y'&gt;&lt;label for='1'&gt;Yes&lt;/label&gt; &lt;/td&gt; &lt;td&gt;&lt;input type = 'radio' name='bills[1]' value = 'n'&gt;&lt;label for='1'&gt;No&lt;/label&gt; &lt;/td&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td&gt;&lt;input type = 'radio' name='bills[8]' value = 'y'&gt;&lt;label for='8'&gt;Yes&lt;/label&gt; &lt;/td&gt; &lt;td&gt;&lt;input type = 'radio' name='bills[8]' value = 'n'&gt;&lt;label for='8'&gt;No&lt;/label&gt; &lt;/td&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td&gt;&lt;input type = 'radio' name='bills[2]' value = 'y'&gt;&lt;label for='2'&gt;Yes&lt;/label&gt; &lt;/td&gt; &lt;td&gt;&lt;input type = 'radio' name='bills[2]' value = 'n'&gt;&lt;label for='2'&gt;No&lt;/label&gt; &lt;/td&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td&gt;&lt;input type = 'radio' name='bills[6]' value = 'y'&gt;&lt;label for='6'&gt;Yes&lt;/label&gt; &lt;/td&gt; &lt;td&gt;&lt;input type = 'radio' name='bills[6]' value = 'n'&gt;&lt;label for='6'&gt;No&lt;/label&gt; &lt;/td&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td&gt;&lt;input type = 'radio' name='bills[3]' value = 'y'&gt;&lt;label for='3'&gt;Yes&lt;/label&gt; &lt;/td&gt; &lt;td&gt;&lt;input type = 'radio' name='bills[3]' value = 'n'&gt;&lt;label for='3'&gt;No&lt;/label&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </code></pre> <p>This returns an array that looks like the following,</p> <pre><code>Array ( [bills] =&gt; Array ( [6] =&gt; y [2] =&gt; n [5] =&gt; n [1] =&gt; y [8] =&gt; y ) ) </code></pre> <p>By using a <code>foreach($_POST['bills'] as $bill)</code> statement I can loop through that array, but how do I get the value of the id, and its respective answer? In the above case, 6, 2, 5, 1, 8.</p>

    1. COChange `foreach($_POST['bills'] as $bill)` to `foreach($_POST['bills'] as $key => $bill)`, the $key will be the key (number) of the item in the array.

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.
