Custom attribute. Set value from shot name.

[Alberto GZ]

I create a custom attribute called "Photo kind" of type Expression and result Text. I want get three coded characters of Shot Name, and return a specific text value.

 

Example: Shot names contain words "AMB", "DET", or "VAR". Then if name contains "DET", text value will be "detail".

 

For this I use a conditional, but I don't see how to evaluate more of two conditions.

 

Here my current sentence for this, but in any Shot Name always show value "ambient" 

{func.IF(self.name <= 'AMB', 'ambient', func.IF(self.name<='DET', '', 'detail'))}

Hi,

 

Try this instead:

{func.IF(self.name <= 'AMB', 'ambient', func.IF(self.name <= 'DET', 'detail', func.IF(self.name <= 'VAR', 'variable', 'none')))}

Let me know what you think.

 

Thanks,

Mattias

Thank you Mattias for your reply.

The sentence on your example also return to me for any shot name 'ambient' value.

I think that only evalue up to first match. There is no 'else' inside conditional?

[Mattias Seebergs]

The IF function syntax is:

func.IF(expression1, expression2, expression3)

which means expression3 is the 'else' statement.

 

I've modified my example slightly, please try the following instead:

{func.IF(func.locate('AMB', self.name), 'ambient', func.IF(func.locate('DET', self.name), 'detail', func.IF(func.locate('VAR', self.name), 'variable', 'none')))}

[Alberto GZ]

Yeah! Now runs ok! Thanks Mattias.

Why enclose condition into location function? What's do it?

[Mattias Seebergs]

The locate function determines if the first parameter ('AMB' for instance) is present in the second parameter (self.name), and if so it returns true, otherwise false.

 

Hope this is more clear now.
