I am using below code to post data with ajax
var oXHR = new XMLHttpRequest();
oXHR.upload.addEventListener('progress', uploadProgress, false);
oXHR.addEventListener('load', uploadFinish, false);
oXHR.addEventListener('error', uploadError, false);
oXHR.addEventListener('abort', uploadAbort, false);
oXHR.open('POST', 'client/uploadvideo');
oXHR.send(vFD);
It is sending txt files but for other like .mp4 file its not working
The issue was upload_max_filesize
and post_max_size
parameters, That required to be set on php.ini.
The error was not mentioning above need to be modified, So at first not understood what was the issue.
Answering this bcause might helpful to anybody
