regexp for user_token

Bernard_Alvarenga

Hello

Just please confirm what is the correct reg exp (PHP) to verify user_token.
From what I saw the user_token looks like: "319925b0-7f56-403e-93ef-1ca3b4b32904".
So, I was thinking that ^[0-9a-z-]+$ should work, unless there are different formats depending on provider.

Pls.advise.

Hi Bernand,

here what we use in one of our plugins:

// Check if a given v4 UUID is valid public static function is_valid_v4 ($uuid) { return preg_match ('/[a-f0-9]{8}-[a-f0-9]{4}-[a-f0-9]{4}-[a-f0-9]{4}-[a-f0-9]{12}/i', trim ($uuid)); }

The format is always the same. The UUID is represented by 32 lowercase hexadecimal digits, displayed in five groups separated by hyphens, in the form 8-4-4-4-12 for a total of 36 characters (32 alphanumeric characters and four hyphens).
