Cat_Nm field is field alias and does not exist in table. So for insert you need to use real field name in ‘name’ property. e.g.

$col[“name”] = “cat”

Your ticket somehow get delayed. If your issue still exist, please send complete code and database dump to regenerate issue here.

Good practice in debugging would be to run this query on sql ide (e.g. phpmyadmin) and correct what is missing then paste expected query here.
