if clause

I'm having problem getting a simple if clause working in the detailed.html template.

I have one field that is a multi-select, and I want to be be able to do the following:

<%if options eq option1%> display option 1 <%endif%>
<%if options eq option2%> display option 2 <%endif%>
<%if options eq option3%> display option 3 <%endif%>

But if more than one option is selected in the multi-select, then nothing is displayed. The "if equal" clause only works if one option is selected.

Any ideas?

Mmm, its actually not as simple as you would expect. Really, what you need to do - is split the value up, and then loop it. For example (untested):

split_up_value

Code:
sub { 
   my @tmp = split /\n|\r/, $_[0]; 
   return { value_split => \@tmp } 
}

..then call with:

Code:
<%split_up_value($Field)%> 
<%loop value_split%> 
   <%loop_value%> <br /> 
<%endloop%>

Hope that helps.

Cheers

Re: [Andy] if clause In reply to

Andy, thanks for your help. Your solution works fine, but what I want to do is slightly more complicated.

The loop you suggested displays an array of the values, ie:

option1
option2
option3

I actually want those values to generate include files within a dynamic detailed page.

Something like this:

<%if options eq option1%>

<%LWP::Simple::get('http://domain.com/option1.html')%>

<%endif%>

<%if options eq option2%>

<%LWP::Simple::get('http://domain.com/option2.html')%>

<%endif%>

Can you see any way of doing this?

Easy - just do:

Code:
<%split_up_value($Field)%> 
<%loop value_split%> 
     <%if loop_value eq "option1"%>  
       <%LWP::Simple::get('http://domain.com/option1.html')%>  
     <%elsif loop_value eq "option2"%>  
       <%LWP::Simple::get('http://domain.com/option2.html')%>  
    <%endif%> 
<%endloop%>

..etc

Cheers
