Fatal error: Call to undefined function file_info_file_types()

It looks like file_info_file_types() was removed from File entity 7.x-2.x. It is still in 7.x-1.x (which is part of Media 7.x-1.x), though.

Here's an attempt at a patch... not sure if it's the best way to fix or whether $reset should be passed as TRUE or FALSE to file_type_get_all_types().

I believe that $reset = TRUE is not needed.

As file_type_get_all_types() does not exist in File entity 7.x-1.x, I'd add some backward compatibility code here. We could use function_exists() to determine which version of File entity is used and then call the right function to get list of all file types.

this includes a function_exists() check. I haven't tested with File entity 7.x-1.x.

Do we need this check here if we convert everything in array above?

something like

No... I meant that it is not needed to check if you convert here.

ahh, I tried that, first but the response of both functions is an array, but one is an array of objects and the other an array of arrays, so I guess the conversion has to take place inside the loop.

Like this then? I added some sting sanitization, since I believe it should be done here.

looks good to me.

Committed. Thanks for your great work!

file_type_get_all_types() was recently renamed to file_type_load_all()
