How about function_exists()?
for example:
if (function_exists('UTW_ShowTagsForCurrentPost')) {
//do stuff
}
That’s one I used to use before 2.3 came out
I need to assign $variable=$post->language;
There is no function involved, obviously.
I could of course pick a function at random, and test it. Then I would be testing the wrong thing, though.
The variable can be empty or contain data, but I don’t want error messages. I haven’t learned php enough to discard error messages, so I was looking for a simple existence check as a quick fix.
So the plugin that you want to check for doesn’t have any functions of it’s own?
I hadn’t run into one like that. Sorry to have consumed bits. :-\
I’m trying to make Gengo work with Eventcalendar3.
Gengo delivers the data structures I need, but it doesn’t have the functions I need (or the documentation that I would need). Either I hack Gengo, or access the data without building functions of my own.
Gengo has lots of functions such as the_language, the_translations, the_translator… Let’s assume that I do a function_exists(the_language) check. The existence of that function does not necessarily mean that Gengo would be installed. It could be just about any plugin that has a the_language function. I want to make sure that the language that is read from the post, is indeed valid data, and that it doesn’t cause any errors.
Anyway, if there is no is_installed() function or similar, then I must just pick some random function. Maybe I’ll find some function that has a unique name, does not get renamed or dropped 🙁 Or make my own (allready did, but that’s really unorthodox way of doing things)
What about something like this?
Granted, I’m not a pro coder – but wouldn’t an active plugin show up in the Plugins panel?
Thank! That was just what I was looking for.
