Website Development
The website technology supporting Philadelphia Reflections is PHP, MySQL and DHTML. The web hosting service is Internet Planners. The development of this website has provided an opportunity to learn new technology, to try out different techniques for getting noticed by the search engines and the trials and tribulations of dealing with malicious hackers and spammers who range from the annoying to the abusive. This collection of articles documents some of our experiences and we hope that people surfing the web looking for solutions to problems we've encountered will benefit.

HTML Forms

How do you (a) open a form when a radio button is clicked (b) in a new window?

Here's how it's done on this website.

  • The radio button is activated by a little JavaScript routine

  • The new window is simply a matter of including the target attribute in the form tag
<html>
<head>

<script type="text/javascript">

	/* javascript function called by the radio buttons 
	     to submit the form when clicked */

	function formSubmit()
	{
	document.getElementById("form_x").submit()
	}
	
</script>

</head>
<body>

  <form name="form_x" id="form_x"
	action="some_routine.php"
	target="newIMGwin"
	method="post" 
	style="whatever">

	<fieldset>
	<legend>legend surrounding the form</legend>

	<input type="radio" name="key" value="1269" onclick="formSubmit()" />

	</fieldset>
  </form>

</body>
</html>
