How to check if multiple parameters have been defined?
I need to check that several URL parameters have been set, is there a cleaner way to do this than what is shown below? In the example I only tested title and body, but I will use many other parameters, and it will be a long code, I wanted to avoid so many ifs, if possible
<txp:if_request type="get" name="title">
<txp:if_request type="get" name="body">
true
</txp:if_request>
</txp:if_request>Offline

Yes, according to the docs you can use the attribute match="any" to test if one of a list of comma-separated values is matched, or match="all" to test for multiple values presence at once.
EDIT: Hmm, maybe not after all. Maybe you can just check against multiple values, not multiples names. If you have a lot of values, perhaps try using rah_repeat to loop over the list and test instead for the not exists case to trigger some output into a variable when the condition doesn’t apply. Check that variable to see if it is empty to determine if you have match for all names.
EDIT II: You might be able to use txp:php and the gpsa function to test multiple get parameters at once, and then test if false is in your array with php. It also loops over the individual get parameters, so I’m not sure whether it’s that much faster.

Hi
For this kind of task i use smd_if plugin you can check multiple values in one test with different logic as you want.
Cheers.

I concur, the only way for checking multiple request variables seems to be a loop, though we could amend it if necessary. This said, in 4.8.8 loops are not difficult. Create a form, say ifrequest:
<txp:if_request not type="get" name='<txp:yield item />' />Now you can save the result of request tests in a variable and then use it as needed:
<txp:variable name="norequest" value="title, body" breakby breakform="ifrequest" />
<txp:if_variable name="norequest">
false
</txp:if_variable>Offline
