How can create script for Is Valid Email ( the mail )

[Msaeed]

Hi all,

I would like to create a script or function for the Email field in case the entry of the email without @ give him an error or an invalid address.

 

thanks a lot for any help or support

You could do a trigger OnObjectSave. The script would use this custom function https://www.briandunning.com/cf/360 and show a dialog. You could just use this part of the CF: 

Left ( yourEmailField ; Position ( yourEmailField ; "@" ; 1; 1 ) - 1 ) ;

Or, you could really go for it and use SendGrid's API to validate the email is real. https://sendgrid.com/docs/api-reference/ Email Address Validation.

I suggest you start with something simple: validate the email field using a calculation =

PatternCount ( Self ; "@" )

This will produce a validation error when you try to commit a record where the email field does not contain the @ character.

Now, this simple solution has several flaws:

1. It fires on record commit, not when user exits the field;
2. The error message can be cryptic and confusing to the user;
3. There are many other ways in which an email address can be invalid.

To solve the first two problems, you can attach an OnObjectValidate script trigger to the field and have it run a script along the lines of:

If [ not PatternCount ( YourTable::Email ; "@" ) ]
  Show Custom Dialog [ "The email is not valid." ]
  Exit Script [ Result: False ] 
End If

IMPORTANT
Script triggers work only on layouts where they have been installed. If you want to ensure data integrity, use the script trigger in addition to field validation, not instead of it.

The third problem is much more complicated and I won't go into it now.

Apparently you are creating a new calculation field, instead of validating the existing email field:
