    <p>No. Only the last input element will be available. </p> <p>If you want multiple inputs with the same name use <code>name="foo[]"</code> for the input name attribute. <code>$_POST</code> will then contain an array for foo with all values from the input elements.</p> <pre><code>&lt;form method="post"&gt; &lt;input name="a[]" value="foo"/&gt; &lt;input name="a[]" value="bar"/&gt; &lt;input name="a[]" value="baz"/&gt; &lt;input type="submit" /&gt; &lt;/form&gt; </code></pre> <p>See the <a href="http://reference.sitepoint.com/html/input/name" rel="noreferrer">HTML reference at Sitepoint</a>.</p> <p>The reason why <code>$_POST</code> will only contain the last value if you don't use <code>[]</code> is because PHP will basically just explode and foreach over the raw query string to populate <code>$_POST</code>. When it encounters a name/value pair that already exists, it will overwrite the previous one.</p> <p>However, you can still access the raw query string like this:</p> <pre><code>$rawQueryString = file_get_contents('php://input')) </code></pre> <p>Assuming you have a form like this:</p> <pre><code>&lt;form method="post"&gt; &lt;input type="hidden" name="a" value="foo"/&gt; &lt;input type="hidden" name="a" value="bar"/&gt; &lt;input type="hidden" name="a" value="baz"/&gt; &lt;input type="submit" /&gt; &lt;/form&gt; </code></pre> <p>the $<code>rawQueryString</code> will then contain <code>a=foo&amp;a=bar&amp;a=baz</code>.</p> <p>You can then use your own logic to parse this into an array. A naive approach would be</p> <pre><code>$post = array(); foreach (explode('&amp;', file_get_contents('php://input')) as $keyValuePair) { list($key, $value) = explode('=', $keyValuePair); $post[$key][] = $value; } </code></pre> <p>which would then give you an array of arrays for each name in the query string.</p>

    1. COok cool, so each input with a duplicate name should just be name="foo[]"? Not name="foo[0]" or anything?

    2. CO@danwellman Just `foo[]` will do but you can also use `foo[0]`, `foo[bar]` and even `foo[bar][baz]`. Just try the various combinations on your webserver to see how they arrive in $_POST.

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
