php htaccess的初学者指南

问题描述：

I have just started learning htaccess.

And i want to test one page :

I have one folder called "favs" and inside that i have a php file index and from that i am passing to the page gallery.php with querystring ID

so the url will be :

mainsite.com/favs/gallery.php?id=7

Now i want the url to be like :

mainsite.com/favs/7

and this is the code i write in .htaccess file :

<IfModule mod_rewrite.c>


RewriteEngine On
RewriteRule ^([a-zA-Z0-9_-]+)$ gallery.php?id=$1
RewriteRule ^([a-zA-Z0-9_-]+)/$ gallery.php?id=$1

</IfModule>

答

Your rules are wrong. You have this:

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteRule ^([a-zA-Z0-9_-]+)$ gallery.php?id=$1
RewriteRule ^([a-zA-Z0-9_-]+)/$ gallery.php?id=$1
</IfModule>

^([a-zA-Z0-9_-]+)$ will match everything in the URL after the first slash, as long as there is no slash. There's a slash in mainsite.com/favs/7, so the rule doesn't match, and it looks for an actual directory named /favs/7. What you want is to match only the piece after favs, like this:

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteRule ^favs/([0-9]+)/?$ favs/gallery.php?id=$1
</IfModule>

The code above is what you should put in .htaccess if it is in your root directory. If it is in your /favs directory, then you need to remove the /favs from RewriteRule and add a RewriteBase like this:

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /favs
RewriteRule ^([0-9]+)/?$ gallery.php?id=$1
</IfModule>

Note: based on your question, I have eliminated letters, _, and - from the regular expression. If you need to match them, you can tweak the rule above accordingly.

the is my full code :

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]



RewriteEngine On
RewriteRule ^favs/([0-9]+)/?$ favs/gallery.php?id=$1

</IfModule>

and this is the url :

http://www.fullridescholarships.net/favs/
