I am pretty new to SuiteCRM and I would like to know how to create custom fields. I did search and read documentation. My understanding that I need to do PHP coding for that. Is my understading correct? Any samples for that? Any documetation how to create custom fields?
How to create for example “Full Name” calculated field that could add automatically “First Name” and “Last Name” into new custom field “Full Name”
SuiteCRM does not have (yet) any calculated fields on layouts. You can do those with PHP (logic hooks).
It does have calculated fields in workflows, so for simple things like addition you can still get the job done. You need to create a Workflow that runs whenever the record is saved, and updates a certain field with an expression.
