i getting last error show invalid file.

i made tutorial after attempted same task, please have look.

upload file, image or videos

  1. please indent code, easy read , find errors.

  2. we have facility check error has occurred , why.

    $_files["file"]["error"] gives error code can decoded form documentation.

  3. i have used file extension finfo (wwhich has made active doing changes in php.ini file) feel better way check mime type of multipart form data.

  4. i have mentioned errors because of max file upload size, execution time etc parameters set default value in php.ini , have changed make operation success.

  5. always can ask thing confuses or error comes in front after reading this.
