Custom Email field validation

how to validate a custom email textfield as normally SuiteCRM use to do?

Thank you


I don’t think you can do this through the Out of the box features in the CRM itself.

You’d have to do this through the code.
I imagine that you’d be able to do run some Custom Javascript on the field that fits your validation requirements.

A blog post by Andy shows how to add Validation for a meeting’s status:
You may be able to re-purpose this for your E-mail field.

You can also have a look at the following issue related to email field validation:

Your email validation might not be working due to the known bug where form can be saved and any email field required rule is ignored.

There is a fix proposed to this issue and it might be relevant to your question.
