Regular Expression working on regexr but not in PHP - FlevasGR - 06-13-2015
Hello, i want to use regex to validate the coupon format. I wrote the rules on regexr.com and it worked fine but not in php.
The expression i have: ([0-9]{3})+(-)+([0-9A-Z]{3})+(-)+([A-Z]{3})
Coupon format:
230-4WE-GAG
424-423-NJB
Basically the first 3 digits are numbers followed by a dash then 3 alphanumeric digits followed by a dash and at the end 3 characters
And the code i have:
PHP Code:
if (preg_match('/([0-9]{3})+(-)+([0-9A-Z]{3})+(-)+([A-Z]{3})/', $coupon)) {
$coupon_data = $this->coupons->check_coupon($coupon);
$this->response($coupon_data, 200);
}
I know that PHP treats regex a little bit different but in which way?

The regex in your php code is not the same regex you posted in "The expression i have". Check the parenthesis. You're missing some.

I think you should append and prepend '#' in your string instead of '/'

Yeah I missed it

Sorry, i made a little mistake as i was pasting this on the forum. The expression is exactly the same.

Try
PHP Code:
preg_match('/[0-9]{3}-[A-Z0-9]{3}-[A-Z]{3}/', $coupon)
3 digits
followed by dash
followed by mixture of 3 digits and/or A-Z chars
followed by dash
followed by 3 chars A-Z

It worked perfectly. So. php doesn't like the ()?
