下划线和破折号无法在变量中识别

Question

I have the following rule in my .htaccess

RewriteRule ^([\da-z]+)/([\da-z]+)/(\d+)/?$ index.php?office=$1&page=$2&news_id=$3 [L,QSA,NC]
RewriteRule ^([\da-z]+)/([\da-z]+)/?$ index.php?office=$1&page=$2 [L,QSA,NC]

when I have an url like: www.test.com/media/continuous-training it doesn't send the continuous-training to the variable. If I don't use dash or underscore everything is fine.

I think the problem is in my regex in the rule, but not sure how to fix it.

Thanks!

Answer 1

You need to add the - and _ to your character class. Use this:

RewriteRule ^([\da-z_-]+)/([\da-z_-]+) ...

Answer 2

You might be better off using [W-] in you character class that will match [A-Za-z0-9_-]

RewriteRule ^([\w-]+)/([\w-]+)/(\d+)/?$ index.php?office=$1&page=$2&news_id=$3 [L,QSA]
RewriteRule ^([\w-]+)/([\w-]+)/?$ index.php?office=$1&page=$2 [L,QSA]
