You can also just set maxlength on the input, and then truncate the value before you use it....

with this example you can see how even though i've given the field a default value longer than the 3 character maxlength, it ignores the excess if you don't change it, and won't let you re-enter a 4th character if you edit the text box.

Code: Select all

	if(! isset($_POST['submit'])) { //not responding to submit ?>
<form action="trystuff.php" method="post" name="example">
	<input type="text" name="foo" maxlength=3 value="bart"/>
	<input type="submit" name="submit" value="checkit">
	} else { //handle submitted data:
	echo 'foo:'.substr($_POST['foo'],0,3);
