php - Uploading files in Fine-Uploader, fail to combine/merge chunks after successful upload -
so i've been trying chunked uploading working project i've been working on, i'm pretty new things, in fact intensive purposes can consider me complete noob teaching himself, i'm using manual upload template website, , traditional server side example files gain understanding of how code works , trying piece them functional example me build from. i've been able things working.
i've managed uploading regular files files folder if upload file without chunking goes files directory, if use chunking works chunk file , upload folder in chunks directory, cant seem figure out how put chunks , place in files directory
my firefox console gives me response , stops after finishing uploading file in chunks regardless of if have chunking success endpoint included in code or not makes me think it's got chunking success endpoint not being set correctly or along lines.
[fine uploader 5.11.8] chunks have been uploaded 0 - finalizing....fine-uploader.js:162:21 [fine uploader 5.11.8] received response status 200 body: {"success":true,"uuid":"79e7db33-9609-49cd-bcb1-2606bea6abd7","uploadname":null}fine-uploader.js:162:21 [fine uploader 5.11.8] finalize successful 0 i've spent 2 days researching no avail, don't seem getting errors, said i'm pretty noob when comes understanding on own. appreciated.

thanks in making sure code correct, kicked myself in face one! thinking longest time incorrectly setup apache environment has been root of problems.
i did not have .htaccess setup seemed fix of problems.
here steps followed resolve problem.
first step
open apache.conf file as
sudo vim /etc/apache2/apache2.conf second step
remove comment sign (#) if find before line ( line number 187 approx.)
accessfilename .htaccess third step
then find line there is
<directory /var/www/> options indexes followsymlinks allowoverride none require granted </directory> replace "none" "all"
allowoverride step 4
activate modrewrite:
sudo a2enmod rewrite sudo service apache2 restart everything should here.
