New validation script completed

Hey everyone

Now I know this isn't directly related to PHP, but some people in this forum have helped me, so now I'm giving back! Here's a neato Javascript-based validator that I think you'll like. I know it doesn't replace server-side, but it's a great first-line.

Some of you may remember a post a-while back in this forum where I talked about this script some. Here it is in all it's glory.

Enjoy! Feedback is welcome!

just a problem with your script

This form assumes your from the USA. it only let me put in a 5 or 9 digit post code, even tho, my post code is 4 numbers, and i had to choose a state.

just something you might wana change, like give people to option to choose a 'non american' state. but if they select a state, say new york, then it also checks the post code as 5 or 9 digits

I haven't tested it for myself, but it looks very nice! Thanks for sharing!

I noticed the zip-problem too.. In Norway we don't have zip codes, we have postal codes.. For example my postal code is 9512

Thanks for the comments.

As I mentioned on the page...this script is quite easy to add functionality to. I could easily add validation for Norway Postal codes (I'd just have to know the rules )

Not sure where I can find list of all the Zip codes per state. Perhaps www.usps.gov will have that info.

Remember, I made this script to be modular! So modify it how you need it!

Check back, if I make updates, I'll post it here.

I also plan to add validation for DECIMALS (ie decimal2|4 would require 2 digits before the decimal, and 4 digits after)

Have suggestions for any other universal or semi-universal datatypes?

I have a feature-idea.. what about giving changing the background-color of the input field that has an error? Make it light-red or something.. (not too far from white, just give it a red tint).. the option to change color should be available too

thats a cool idea, that could work really nicely

What you could actually do is let users specify their own postcode/state validation rules so they can customize it. then you could just use the eval() function to check it...something like this:

<script language="JavaScript">

var rule="pcode.value.length == 4 && pcode.value >= 2000";

function checkPCode(pcode)
{
if(eval("rule"))
// OK
else
// Failed
}
</script>

you get the idea...just a way to customize it

True, but this script is intended for web authors, not the general public of users. I really don't want to start the complexities of generating accurate regular expressions based on user input. A good idea, but not sure I'll use it here.

I'm working on the field coloring now....

OH, I did find the ZIP code data I needed to validate the Zip Code vs the State, but I'd have to pay for it... So that will be on hold for a bit...

Thanks for the comments! Keep em comin!

Ok, I've worked on this a bit, and have the new version ready

What's new:
1) Validates decimals (thats floats to you programming geeks ) within any rules
2) Validates money (US or similar currency) flexible formats
3) Provides coloring for error fields via CSS (thx for the idea Havard )


Enjoy!

Ok, I've been toiling....

The validator now includes:

• Credit Card validation against card rules and Mod 10 Algorithm
• New validation type for SELECT objects
• Format validation without requiring field entirely
• onSubmit() controls for confirming submission and disabling submit
• Flexible messaging
• Better error messages
• Better documentation

Enjoy!

Note: If by chance you have aleady used a previous version (1.01, 1.11, 1.42) and you want to start using this version, please re-read the documentation, because some of the rules have changed and your page(s) will need updating.

It seems like it's trying to validate the input when I click on the hotscripts rate submit button

Woopsie....sorry about that. I think my cut & pasting got a bit over-zealous or something. Should work now.

very good! i have one last suggestion, for the us states and post code, you should make a seperate file, containing variables for the postcode length and an array of the states, that means people can easily modify your code

Just an idea
