Question

Here my .htaccess

Options +FollowSymLinks

RewriteEngine on
RewriteCond %{REQUEST_URI} \/([0-9a-zA-Z]+)$ [NC]
RewriteRule ^(.*) image.php?names[]=%1 [L]

RewriteCond %{REQUEST_URI} \/([0-9a-zA-Z]+),([0-9a-zA-Z]+)$ [NC]
RewriteRule ^(.*) image.php?names[]=%1&names[]=%2 [L]

RewriteCond %{REQUEST_URI} \/([0-9a-zA-Z]+),([0-9a-zA-Z]+),([0-9a-zA-Z]+)$ [NC]
RewriteRule ^(.*) image.php?names[]=%1&names[]=%2&names[]=%3 [L]

RewriteCond %{REQUEST_URI} \/gallery/([0-9a-zA-Z]+)$ [NC]
RewriteRule ^(.*) gallery.php?id[]=%1 [L]

this 2 strings doesn’t work correctly

RewriteCond %{REQUEST_URI} \/gallery/([0-9a-zA-Z]+)$ [NC]
RewriteRule ^(.*) gallery.php?id[]=%1 [L]

When I go to gallery/hgJ56 , I see the content of first 2 strings

RewriteCond %{REQUEST_URI} \/([0-9a-zA-Z]+)$ [NC]
RewriteRule ^(.*) image.php?names[]=%1 [L]

I’m in trouble, can’t understand^, please help! What can I do ?

Answer 1

This rule

RewriteCond %{REQUEST_URI} /([0-9a-zA-Z]+)$ [NC]

will match a string that ends with a / followed by an alphanumeric string, so it will match gallery/hgJ56, because it ends with /hgJF6.

If the rule is only supposed to match a string that begins with a / followed by an alphanumeric string, then you can change this rule to

RewriteCond %{REQUEST_URI} ^/([0-9a-zA-Z]+)$ [NC]

and it will not longer match gallery/hgJ56 and your other rule will work.

Note that you do not need to escape the / character i.e. \/ and just / are equivalent.

You may also want to apply the ^ to the rest of your rules in case they also are only supposed to match the start of the string i.e change

RewriteCond %{REQUEST_URI} \/gallery/([0-9a-zA-Z]+)$ [NC]

to

RewriteCond %{REQUEST_URI} ^/gallery/([0-9a-zA-Z]+)$ [NC]
