    <p>I need a quick way to validate in php or javascript whether a date is an invalid date such as (2/31 or 04/31 - since they dont exist), ALONG with if it is a LEAP year or not. </p> <p><strong>My code:</strong></p> <pre><code>&lt;?php $month = $_POST["mo"]; $day = $_POST["theDay"]; $yr = $_POST["year"]; if (!isset($_POST['submit'])) { // if page is not submitted; echo form ?&gt; &lt;h2 style="margin:0; padding:0;"&gt;Date Selection&lt;/h2&gt; &lt;span style="color:gray; font-size:0.8em;"&gt;By Joseph Dickinson&lt;/span&gt; &lt;FORM method="POST" action="&lt;?php echo $PHP_SELF;?&gt;"&gt; &lt;select name="mo"&gt; &lt;option disabled="disabled"&gt;SELECT MONTH&lt;/option&gt; &lt;option&gt;January&lt;/option&gt; &lt;option&gt;February&lt;/option&gt; &lt;option&gt;March&lt;/option&gt; &lt;option&gt;April&lt;/option&gt; &lt;option&gt;May&lt;/option&gt; &lt;option&gt;June&lt;/option&gt; &lt;option&gt;July&lt;/option&gt; &lt;option&gt;August&lt;/option&gt; &lt;option&gt;September&lt;/option&gt; &lt;option&gt;October&lt;/option&gt; &lt;option&gt;November&lt;/option&gt; &lt;option&gt;December&lt;/option&gt; &lt;/select&gt; &lt;select name="theDay"&gt; &lt;option disabled="disabled"&gt;SELECT DAY&lt;/option&gt; &lt;option&gt;1&lt;/option&gt; &lt;option&gt;2&lt;/option&gt; &lt;option&gt;3&lt;/option&gt; &lt;option&gt;4&lt;/option&gt; &lt;option&gt;5&lt;/option&gt; &lt;option&gt;6&lt;/option&gt; &lt;option&gt;7&lt;/option&gt; &lt;option&gt;8&lt;/option&gt; &lt;option&gt;9&lt;/option&gt; &lt;option&gt;10&lt;/option&gt; &lt;option&gt;11&lt;/option&gt; &lt;option&gt;12&lt;/option&gt; &lt;option&gt;13&lt;/option&gt; &lt;option&gt;14&lt;/option&gt; &lt;option&gt;15&lt;/option&gt; &lt;option&gt;16&lt;/option&gt; &lt;option&gt;17&lt;/option&gt; &lt;option&gt;18&lt;/option&gt; &lt;option&gt;19&lt;/option&gt; &lt;option&gt;20&lt;/option&gt; &lt;option&gt;21&lt;/option&gt; &lt;option&gt;22&lt;/option&gt; &lt;option&gt;23&lt;/option&gt; &lt;option&gt;24&lt;/option&gt; &lt;option&gt;25&lt;/option&gt; &lt;option&gt;26&lt;/option&gt; &lt;option&gt;27&lt;/option&gt; &lt;option&gt;28&lt;/option&gt; &lt;option&gt;29&lt;/option&gt; &lt;option&gt;30&lt;/option&gt; &lt;option&gt;31&lt;/option&gt; &lt;/select&gt; &lt;select name="year"&gt; &lt;option disabled="disabled"&gt;SELECT YEAR&lt;/option&gt; &lt;option&gt;2011&lt;/option&gt; &lt;option&gt;2010&lt;/option&gt; &lt;option&gt;2009&lt;/option&gt; &lt;option&gt;2008&lt;/option&gt; &lt;option&gt;2007&lt;/option&gt; &lt;option&gt;2006&lt;/option&gt; &lt;option&gt;2005&lt;/option&gt; &lt;option&gt;2004&lt;/option&gt; &lt;option&gt;2003&lt;/option&gt; &lt;option&gt;2002&lt;/option&gt; &lt;option&gt;2001&lt;/option&gt; &lt;option&gt;2000&lt;/option&gt; &lt;option&gt;1999&lt;/option&gt; &lt;option&gt;1998&lt;/option&gt; &lt;option&gt;1997&lt;/option&gt; &lt;option&gt;1996&lt;/option&gt; &lt;option&gt;1995&lt;/option&gt; &lt;option&gt;1994&lt;/option&gt; &lt;option&gt;1993&lt;/option&gt; &lt;option&gt;1992&lt;/option&gt; &lt;option&gt;1991&lt;/option&gt; &lt;option&gt;1990&lt;/option&gt; &lt;option&gt;1989&lt;/option&gt; &lt;option&gt;1988&lt;/option&gt; &lt;option&gt;1987&lt;/option&gt; &lt;option&gt;1986&lt;/option&gt; &lt;option&gt;1985&lt;/option&gt; &lt;option&gt;1984&lt;/option&gt; &lt;option&gt;1983&lt;/option&gt; &lt;option&gt;1982&lt;/option&gt; &lt;option&gt;1981&lt;/option&gt; &lt;option&gt;1982&lt;/option&gt; &lt;/select&gt; &lt;INPUT TYPE="submit" value="Send" name="submit" /&gt; &lt;/FORM&gt; &lt;? } else { echo "You chose: " .

    1. COIt is certainly better to have that check both on the client side and server side. Do you use a JavaScript library?

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.

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