I’m currently researching this but wondering if anyone can help point in the right direction.
I want to allow people to connect to a website and download PDF files and then view them when they’re offline. I have most of this system already set up, explained below.
The PDF files are automatically generated by the system and relate each to a job that needs completing, so each one is unique.
Currently the website is set up and people can view the PDF files and of course print them, but there is no offline access.
All access is done using mobile phones (recent and older ones) and compatibility with these is very important.
I am thinking of the following:
(1) When they go to view the usual page, they will be able to see it if they have an internet connection. If not they will see another page (I’m guessing HTML 5 offline storage can do this???).
(2) When they view this page online, they are also offered the file to download (rather than view and print). I’m guessing this is possible. I know many older mobiles just offer download anyway as they struggle to display (not iOS of course).
(3) When they access the page offline, what appears is a list of all the PDF files they have previously downloaded . They can then view these.
Another important thing is that each job has a unique ‘job’ number and the filenames account for this (e.g. 234319.pdf) - and whenever anyone goes onto the online system, I want an updated file to be produced (as adjustments can often be made), and this must overwrite the old one.
So the idea is they go online, pull off the latest files for each job (which overwrites any old job files) and then they can view these when offline.
The great thing is I can just tell people to access www.site.com and they will either see the online or the offline version. As we are a company, simple instructions to employees always helps with its take up.
Is the above possible or is there a better method, and if above sounds good can all this be done with PHP / HTML 5 etc. or is there a cross-device app (iOS, Android, BB etc.) that can control all this?
Offline access is important as some people will only be able to access at company headquarters (where they can download), but will need to view when out and about.
Anyone have any thoughts?
