Hi I have products with a fair few custom attributes which are all working fine. I have two Multiple selects however that do not save what I enter in them!

All other text fields, dropdowns etc all save fine but it doesn't matter if I select one or ten options on the multiple selects they don't save, save and continue or just save, it doesn't make a difference!

Has anyone had this occur or does anyone have any suggestions?


  • did you create this multi select attribute directly from admin or by any script ? Commented Oct 1, 2015 at 16:37
  • Try to do a cache flush Commented Oct 2, 2015 at 0:36
  • Hi, I tried clearing cache and index with no luck. It is just the default admin area way of doing it no custom scripts used :( Commented Oct 2, 2015 at 7:52

Check your eav_attribute table for that attribute. The backend_type should be text (not varchar), and the backend_model should be Magento\Eav\Model\Entity\Attribute\Backend\ArrayBackend
