I try to upload a .pptx file to my server folder named "lesson" and copy that file from the same folder and rename that copied file with .odp extension.
I used ViewerJS plugin and it really work nicely when i open a pdf file.
However. my problem is that when i try to link the .odp file, ViewerJS doesnt finish loading. How can I solve this? Please help
Heres my code for tranforming the copied .pptx file to .odp. file
$oldname = $file;
$newname = basename($file,".pptx");
$n = $newname.".odp";
