Call to undefined function browscap_get_browser() in ... mt_browscap.module on line 20

I had the same problem with version 6.x-2.7, I'm not sure whats causing it because I can comment out line 20 and run browscap_get_browser() and it returns an array.

So for a work around I did...
Comment out line 20
#$user_agent = browscap_get_browser();
Add the function from the module browscap/browscap.module (version 6.x-2.0) line 76 to line 126 and rename the function to tmp_browscap_get_browser().
Then add below the new function $user_agent = tmp_browscap_get_browser();

I'm not 100% sure on how this overall affects the site, but it got my mobile site back up and running with no global fatal errors and figure it's safe since it's using the same code as the browscap module.

I've also attached mt_browscap.module which is named mt_browscap.txt for upload purposes.

Hope this helps!

@dallasw1983,

Thanks for this, I had the same issue using 2.x-dev of mobile tools and the 2.0 version (D6) of browscap. Your updated module file fixed my issue too.

While the fix appears to resolve the issue, it bothers me that the code needs to be duplicated. I thought it might be a module weight issue, so I tried setting browscap's weight to -5, in theory that should load it before mobile tools (default weight of 50) and mt_browscap (default weight of 0), which did not resolve the problem.

Like Alf, I had the same issue. I had it with both the mobile_tools 2.3 and the 2.7 module. The Browscap 1.5 version worked fine, but upgrading to 2.x kills the site.

However, the issue only seems to appear when caching is enable. Disable caching and everything works fine. Enable caching and the site dies, with the undefined function message. Clearing the cache does not appear to help the situation either.

So the issue appears to reside in the way the functions are cached. But I haven't figured out exactly how yet.

Thanks for the fix, that is a big help.

Thank you for this fix.

#6 solved the issue for me, and I really appreciate it because the site was just error-ing out on every page, including all admin pages.

I wonder if a better solution to #6 might be
drupal_load('module', browscap);

Yes, #8 worked for me. I agree that it is a better solution.

I updated my module to 6.x-2.7+3-dev (2013-Feb-22) today, got the same error again, and #8 worked for me. Thanks again!

Also came across same issue and #8 worked like a charm! Thanks guys =]]

I've created a patch including the solution from #8, as well as a fix for erraneous mobile detection when used with Browscap 2.x.

#8 worked for me. I'll change this to "reviewed an tested by the community" since it seems that it's worked for people. (change it back if I'm wrong) :)

I can confirm that the patch in #12 works.

#8 tested here too. It works like a charm.

Patch in #12 works for me.

Running browscap with mobile tools took down my site. Patch in #12 resolved the issue quite nicely. Danke!

I had the same issue. #12 works for me. Thank you!

I am closing this issue, as it's for a Drupal version no longer supported.
