htaccess returning 500 error when needs to be 404

问题:

How can I make it so that my htaccess rules return a 404 when invalid urls are entered into the address bar.

The two rules that are causing this

RewriteRule ^submit/([a-z]+)/([0-9]+)$ /submit?c=$1&i=$2 [L]

RewriteRule ^test/([a-z]+)/([0-9]+)/([0-9]+)$ /test?c=$1&i=$2&q=$3 [L]

Both the rules work fine when a correct url is entered but say for example one of the last parameters is not a number, it returns a 500 error.

How can I make it so that if these rules are not matched then it'll return a 404.

To further clarify take the following url test/cooking/9/1 is valid. So is submit/cooking/9.

It returns 500 with urls that dont match the rewrite such as these, 'test/cooking/9/1/1,submit/0/0/0`, I would like it to return a 404 if the rules outlined above are NOT matched.

This is happening because apache is reading the URI as part of the PATH INFO, and parts of test or submit is matching the -f check eventhough the rest of the path doesn't. Try changing the -f check to:

RewriteCond %{DOCUMENT_ROOT}%{REQUEST_URI}\.php -f

instead of:

RewriteCond %{REQUEST_FILENAME}\.php -f
