creating a PHP wrapper script?
in [General]
|
From: "Robert P. J. Day" on 23 Apr 2010 11:18 i'm sure this isn't hard to do, but i'm having end-of-week brain cramps. just now, i installed a PHP package that lets me download thumbnails of image files stored on a server -- the URL to generate and download a thumbnail is, say: http://server/d1/d2/thumbnail.php?fileID=whatever&arg1=val1&arg2=val2 and so on. unsurprisingly, the thumbnail generation program accepts numerous arguments and is incredibly sophisticated, and is stored in a subdirectory under /var/www/html and ... well, you get the idea, calling it directly involves creating quite the URL. instead, i'd like to stuff a wrapper script at the top of the document root which hides all that complexity, so i can just browse to: http://server/thumb.php?fileID=whatever and have that top-level thumb.php script make the appropriate invocation to the real thumbnail.php script with all of those (default) arguments and values. so, what would thumb.php look like? i obviously need to simulate a POST call, retrieve the output and pass it back unchanged. thoughts? surely this is something that people want to do on a regular basis, no? rday -- ======================================================================== Robert P.

From: Danilo Moncastro Sabbagh on 25 Apr 2010 16:53 Even tho most of the servers uses 1.1 they have compliant configurations. or at least they should. things like mod_gzip and deflate are usually only used if the request is 1.1 to be honest.. if i understood you correctly the curl solution or even a wrapper for another downloader like wget or aria is possible... but id guess that a more fast and simple solution could be archived with a javascript chamging the image srcs or an ajax request with jquery or other popular yet simple js lib.
