.htaccess — Variable location of affected folder -

i have php script generate placeholder images, placehold.it service. wanted custom 1 prevent latency occurs free online services.

i have included script inside of folder ./assets/placeholder/ in personal front-end boilerplate. why need .htaccess adapts current location of placeholder folder, not root.

the script takes following parameters: d (dimension, eg. 400, 250x100), bg (background color), color (text color) , text.

ideally, url work following ./assets/placeholder/300x200/eaeaea/333333?text=test, text being regular var.

here .htaccess put while ago. works provided file in root directory:

rewriteengine on rewriterule ^#([^/]*)/([^/]*)/([^/]*)$ index.php?d=$1&bg=$2&color=$3 [qsa] 

in 1 sentence, if move file (index.php) root /some/other/dir/index.php, want .htaccess file still function without have change rewritebase or anything.

i have found this article on matter, don't have enough knowledge on subject make fit case.

thanks in advance!

update: decided move .htaccess file root of project. thing not working adding of / @ end, before ?

## turn mod_rewrite engine on ## rewriteengine on  # no trailing / ? rewritecond %{request_uri} !(.*)/$ # add slash.  rewriterule assets/placeholder/(.*)$ assets/placeholder/$1/ [l,r=301]  # map parameters vars rewriterule assets/placeholder/?([^/]*)/?([^/]*)/?([^/]*)/$ assets/placeholder/index.php?d=$1&bg=$2&color=$3 [qsa] 

change url .assets/placeholder/300x200/eaeaea/333333&text=test .assets/placeholder/300x200/eaeaea/333333?text=test if want qsa flag runs.

and try code :

rewriteengine on rewriterule ^assets/placeholder/([^/]*)/([^/]*)/([^/]*)$ index.php?d=$1&bg=$2&color=$3 [qsa] 

try code redirection url end slash :

rewritecond %{request_uri} !^([^/]*)/$ rewriterule assets/placeholder/(.*)$ assets/placeholder/$1/ [l,r=301]
