Error if phone field not in the right format?

[frenchie]

I've been using the Form2Mail Dreamweaver extension since I don't know the PHP language at all, and it's been working pretty well, although I've been getting spams lately so I added a Captcha key, but I wanted to keep the key simple (reCaptcha can be hard to read sometimes). So I believe the robots can still decode it.

All the spam I've been receiving have one thing in common: the phone number field is filled by random letters. Is there anyway to edit the PHP so that if the phone field does not have numbers it goes to the error page?
The field still needs to accept spaces, "+", "-" and".". I also want to work if it is blank, only blocking anyone filling it with only letters.

I'd appreciate very much if someone could help me out, let me know if you need more information.

Here is the code. Sorry guys, too many characters to paste it here.

Code: Select all

if (preg_match('/[a-aA-Z]/',$_POST['phone_number'])) { 
  die ("Oops.. Telephone number is horrible....");
}
 

** Disclaimer
This is quick and very dirty, but it works.
Obviously you can change the die to be anything you want it to be.. but this will get you in the general direction of where you need to go.

Hey thanks a lot! Where exactly should I put it in the code?

[frenchie]

I don't know PHP at all, but are you sure it's [a-aA-Z] ? It seems logical to me that it should be something like [a-zA-Z]. Let me know if I'm wrong.

[egami]

You're right, a-zA-Z, typo.. sorry.

[frenchie]

No problem, thanks. Where should I insert it? Anywhere in the file?

[egami]

Well that I don't know, I haven't seen your script.

I would put it where you are parsing the input information, and see where it goes from there.

[frenchie]

The script is VERY detailed and long, but for some reason they're not using the basic PHP I'm used to see.
I have tried different places, but it didn't work...

Do you mind having a quick look to help me out? The file is linked in my first post.

Well, not to be a snob (although I kind of am when it comes to my computer and the Internet), but I don't click on links that I don't know/trust.

Find where you are doing the current processing, and play around a little. Make sure you have a backup of your current code.

[frenchie]

Wooooo ! I found it! Thanks.

And by the way the link is to a box.net page. It just shows up the file, no download or spam or virus or anything to worry about as far as I know... (Well I had to defend the fact that I post trustworthy links!)

Is there any way to make the message a pop up box so it doesn't leave the page?
