Check if globabls_get exists/is defined

Hello,

I have a problem, I’m trying to use conditions (conditions screen or conditional keywords) to determine if a globals_get_ variable exists.

So say i have a url, blah.com/page?qwert

qwert has no value, but I need to use conditions to check if it’s there or not. I can’t use globals_get_qwert^empty: or something similar because it will always be empty whether the ?qwert is there or not. I’ve tried in ssjs and csjs and it still doesn’t work because globals_get_qwert will always output nothing whether its there or not.

Hopefully thats easy to understand. Is there a keyword im unaware of that does this or a way to do this?

Cheers,
Grant

You could get the whole querystring with %globals_server_query_string% and check that (but of course you’d need to be careful to distinguish between ?qwert and ?search=qwerty

Thats what I went with after I realised conditions wouldn’t work, I did it with csjs thought and searched through url params.

Was just curious if there was a way, it feels like there should be

Couldn’t you use use %globals_get^array_key_exists:qwert%?

That keyword returns True (1) if the keyword exists and is not confused by qwerty or similar variables.

I did not know you could access get params like that, good to know!

Thank you, this worked great!

No problem. That keyword works very well in situations where you need to check whether the variable exists as a non-null key-value pair or just a key/variable (like your situation).

So…

%begin_globals_get_var%
...
%else_begin_globals_get^array_key_exists:var%
...
%else_globals%
...
%end_globals%
