htaccess regex, allow underscores

Question

Here is our current regex:

RewriteRule ^share/([a-zA-Z0-9-]+)/([a-zA-Z0-9-]+)/?$ /v.php?v=$1&hash=$2 [L]

This isn't allowing underscores "_" - how do we get this to allow underscores?

Thank you

Answer 1

You can shorten your regex like this as well. Now this will allow _ also. \w is shorthand for [a-zA-Z0-9_]

RewriteRule ^share/([\w-]+)/([\w-]+)/?$ /v.php?v=$1&hash=$2 [L]

Answer 2

By adding _ to both expressions within the braces []:

RewriteRule ^share/([a-zA-Z0-9_-]+)/([a-zA-Z0-9_-]+)/?$ /v.php?v=$1&hash=$2 [L]
