Minimum length in form field

Sorry Forrest... but it's easier in JavaScript:
1) Set up a js function like this ...
function minium_length_check( ) {
var myForm=document.getElementsByTagName("form"][0];
var myField=myForm.telephone.value;
var minimum = 5;
if (myNbr.length >= minimum) {
return;
} else {
alert( 'Telephone Numbers MUST be at least ' + minimum + ' characters in length!");
myField.focus();
myField.select();
return
}

2) add an "onblur" event to the input field:
<input type="text" name="telephone" size="10" maxlength="16" onblur="javascript:minimum_length_check();" />

... Just be certain to check the length a 2nd time when the data are submitted because the "onblur" event only fires after the viewer gets to - and attempts to leave - the field. But who is to say that they will ever actually visit that field?

The only other way is check it once the form has been submitted. That's a good solution, even if you use JavaScript. If it is that important, you should check it even after it has passed the JavaScript and been submitted. Take t from a person who has made that mistake.

It's kind of like the old carpenters adage, "measure once, measure twice, cut". Here you should "check once" with JavaScript then "check twice" once the form has been submitted. Not sure where the "cut" comes into play?

Thanks Phil but I can't use javascript.

Will <cfinput message="Please enter a valid Phone Number" name="txt_phone" required="yes" type="text" validate="telephone"> work?
