Re: [VuFind-Tech] mobile device detection

[Lutz B. <lbi...@nl...>]

Hi,
Makes sense, the new patch checks if the mobile theme is set.

Regarding 2.) one thing we are going to do is implement a
"notAvailableMobile.tpl" which gets displayed on pages that aren't
implemented in the mobile view when the user is using the mobile theme.
It redirects the user to the standard view if they want to access that
particular feature or they can go to the mobile homepage or use the back
button to stay in the mobile theme.

It's not ideal from an implementation point, since we need to add a .tpl
file for each "unimplemented" page, otherwise we get a smarty error(of
course these errors exist now also when accessing those pages directly
with an url for example). The place we noticed this is the collections
module, since we will have links to collection pages, and those links
may be opened from mobile devices. However we don't plan on implementing
the functionality in the mobile view as it's probably too complex. So
under the mobile theme templates we have "Collection/view.tpl" and
"Collection/view-alt.tpl" which just include the
"notAvailableMobile.tpl" file.

Another problem with this behavior may be that we play "theme ping pong"
with the user: "try our mobile view!"... "This page needs standard
view."... etc.

Still for us at least it's probably better to keep the user on the
current page rather then going to the homepage when switching to the
mobile theme, so they don't have to do a complicated search(which might
not be possible anyways) in the mobile view just to find the record they
were looking at previously. 

I left that part unchanged as of yet, but if you have a clear preference
for the trunk, let me know and I can have a go at implementing it.

Cheers,
Lutz

Thanks, Lutz!  A couple of comments:

1.) You should check if the mobile_theme is turned on in config.ini; we
don't want to display a "switch to mobile view" link on a site that has
mobile view disabled.

2.) I'm not sure if it's worth all the effort of recreating the current
URL for the link -- since the mobile themes generally have less
functionality than the non-mobile themes, there's a chance that the URL
won't actually work in mobile mode.  Perhaps it would be safer to simply
point to the mobile home page.  If you feel it's better to keep the
current URL, another possibility would be to use a POST form with a
blank action in the user interface -- then you don't need to do as much
work on the server side (though you would have to add POST processing to
the 'ui' parameter handling in web/sys/Interface.php).
