PHP error with Low Variables options tag

Stephen 25 Oct 2013 15:14 problem, complete

I'm getting a PHP error when I use the exp:low_variables:options tag to pull in data from a Select Entries variable.

Here's the code I'm using:

{exp:low_variables:options var="lv_variable_name"}{lv_variable_name:data}
{/exp:low_variables:options}

Here's the PHP Error:

A PHP Error was encountered
Severity: Warning
Message: Invalid argument supplied for foreach()
Filename: low_variables/mod.low_variables.php
Line Number: 333

I'm running EE 2.7.2. Other Low Variables tags seem to work fine - I'm only getting this error with the options tag.

Thanks for your help.

   What type is the variable in question?
   
   Edit: Sorry, a Select Entries one. That one doesn't have any options to display. Use the Parse/Multiple tag instead to loop through the values.

   Also, I'll make sure LV fails gracefully instead of generating that error.

   Thanks, Low. I was just reading quickly and misread the documentation for the Options tag where is says "This tag pair allows you to display the options for a given variable. Use this in combination with the Checkbox Group, Radio Group and Select variable types. "
   
   So my thinking was the options tag would loop through the select entries, but now it makes sense that it would just loop through the actual options for that variable.
   
   Thanks for the quick response.
