Can I test a field for being not empty?

Daniel Kaminski 6 Aug 2013 07:32 question, complete

Hello,

is there a way with low_search to simply test that a field is not empty?

e.g. doing an exact search in field A and only including entries where field B is not empty

Thanks,
Daniel

   You can use any of the search:field_name values, including search:field_name="not IS_EMPTY". In an input field that would mean:
   
   

   <input name="search:field_name" value="not IS_EMPTY" />

   First of all, thanks for the quick reply.
   
   It is clear now how to test a field, for not being being, but seeing your answer I wonder how can I control the AND and OR conjunctions?
   
   What I'm currently doing is, I dynamically build multiple input fields which look all into the same channel field.
   
   Is there a way to perform a search with the following structure?
   
   WHERE (field-a contains term1 OR field-a contains term2) AND (field-b is not empty)
   
   cheers,
   Daniel

   The same principle applies. These parameters:
   
   

   search:field-a="term1|term2" search:field-b="not IS_EMPTY"

   
   
   Which translates to input fields like this:
   
   

   <input name="search:field-a" value="term1|term2" /> 
    <input name="search:field-b" value="not IS_EMPTY" />

   
   
   or
   
   

   <input name="search:field-a[]" value="term1" /> 
    <input name="search:field-a[]" value="term2" /> 
    <input name="search:field-b" value="not IS_EMPTY" />

   
   
   Note that I'm using [] behind the input name if it takes multiple values.
