.htaccess - How to do a mod_rewrite with varying number of variables -
this question has answer here:
i have mod_rewrite rule has 3 variables so:
rewriterule ^page/(.*)/(.*)/(.*)$ page.php?a=$1&b=$2&c=$3 the 3rd variable isn't mandatory, first 2. problem occurs when attempts hit url first 2 in place page/blah/blah or page/blah/blah/
i understand can have 2 rules, e.g:
rewriterule ^page/(.*)/(.*)/(.*)$ page.php?a=$1&b=$2&c=$3 rewriterule ^page/(.*)/(.*)$ page.php?a=$1&b=$2 but seems longwinded.
how can write flexible rule allows 3 url possibilities arrive @ same page?
/page/blah/blah/blah//page/blah/blah/page/blah/blah/
you may try in 1 .htaccess file @ root directory:
options +followsymlinks -multiviews rewriteengine on rewritebase / rewritecond %{request_uri} !page\.php [nc] rewriterule ^page/([^/]+)/([^/]+)/?([^/]+)?/? /page.php?a=$1&b=$2&c=$3 [l,nc] third parameter optional , key c empty when there 2 parameters.
if don't want empty key value, replace above rule-set one:
options +followsymlinks -multiviews rewriteengine on rewritebase / rewritecond %{request_uri} !page\.php [nc] rewriterule ^page/([^/]+)/([^/]+)/([^/]+)/? /page.php?a=$1&b=$2&c=$3 [l,nc] rewritecond %{request_uri} !page\.php [nc] rewriterule ^page/([^/]+)/([^/]+/?$ /page.php?a=$1&b=$2 [l,nc]
