Using a text box for City, State or Zip. 1

fooobee · Apr 25, 2006

Does anyone have a code sample on how I can use a text box for location (City, State or Zip). I need to determine what has been entered and then parse/pass the values to a webservice and/or search query. An example would be how CareerBuilder does it on their homepage.

Thanks.

It shouldn't be hard.

U.S. ZIP codes are a 5-digit number optionally followed by a dash and a four-digit number.
States have two letters.
Anything else could be assumed to be a city name.

Using a test form like:

Code:

<html><body>
<form method="post" action="/test_csz.php">
<input type="text" name="value"><input type="submit">
</form></body></html>

Maybe something along the lines of:

Code:

<?php
if (isset($_POST['value']))
{
	if (preg_match ('/^\d{5}(-\d{4})?$/', $_POST['value']))
	{
		print 'ZIP code';
	}
	else
	{
		if (preg_match ('/^[a-z]{2}$/i', $_POST['value']))
		{
			print 'State abbreviation';
		}
		else
		{
			print "assuming it's a city name";
		}
	}
}
?>

will do the trick
