[RESOLVED] form address validation

[kingdm]

Good day/evening,

I have this problem in my form validation regarding the address input. I want my address to validate the input against special characters except the comma (,) and period (.) . I found a thread here that almost meet my validation but it consider the comma and period to be invalid also, how can I make the comma and period to be valid using this script I found here. Thanks mate for the help.

Here is the script.

if(preg_match_all('/[^a-z0-9_~]/i', $city_add, $invalid)) 
	{ 
	   $errors2[] = "Your address contains invalid character: " . join('',array_unique($invalid[0]));
	}

You need to modify your regex to accept those characters. Add in ., and that should match the comma and period characters. Also, are you aware that your regex is only matching the start of the string, which could potentially only be one character. You need to add a $ before that closing ]

Thanks for the reply Ashley.

I did understand your explanation but actually I'm having a hard time in implementing my idea when it comes to regex. As I stated earlier I found this script here in other threads, because I give up in making my own. 🙁

How will I modify this one based on your suggestion?

I really appreciate your reply. Thanks.

Well add .,$ before the ] on the regex.
