I want to filter multiselect product attribute which has backend type Magento\Eav\Model\Entity\Attribute\Backend\ArrayBackend. So when I save attribute it gets saved as the comma-separated values in the database. So at the time of Product filtering, I applied filter by 2 values as like this

 $this->collection->addAttributeToFilter( 'concerns', array('finset' => 'concerns_1,concerns_4'));

It's not filtering with the above code (means collection size returning zero) but when I filter on a single value its working fine. Please suggest me how can I filter on multiple values. Thanks in advance.

  • I think one problem with FIND_IN_SET is that it does not check for multiple values at one time. suppose I'm writing SELECT FIND_IN_SET('a,b','a,b,c,d'); its returning 0 however both a & b are in the set , but when I write SELECT FIND_IN_SET('b','a,b,c,d'); its returning 2.

Need to pass to the addAttributeToFilter and array of arrays.

          array('attribute'=>'concerns', 'finset'=>'a'),
          array('attribute'=>'concerns', 'finset'=>'b'),

Updated :-

->addAttributeToFilter('concerns', array('in' => $array));
  • I have tried this but it's not working. My question was suppose one product has attribute values a,b,c,d and I want to filter on attribute a,d then how can I do that? I tried your as you have provided here but it's not working @rkrathod

  • Can we do it in one line? is it possible? because my attribute values are dynamic some time it might have 3 values some time might have 4 value etc. can we handle that type of scenario?
