    Validating Email Address in Peoplecode

    We have a number of pages in PeopleSoft, where user/admin is free to enter email addresses. How to validate if a value entered in a PeopleSoft field is a valid email address?

    In general, how does an email id look like? It will have few characters followed by @ symbol followed by few characters and then a .(dot) symbol followed by few more characters. So, we have to validate the presence of these.

    For example, if &email_addr is a variable which contains the string entered in email address field and needs to be validated then try the below code:
    &AT = Find("@", &email_addr);
    &DOT = Find(".", &email_addr);

    If ALL(%AT,&DOT) Then
    /* Validation Success */
    Else
    /* Validation Fail*/
    /* Issue Error message */
    End-if;


    Additionally we could also perform checks to ensure that:
    • the position of @ is not the first character
    • .(dot) is not the last character.
    • @ is not repeated else where in the string
    • Dot is not repeated else where in the string
    This can be done by using instr, substr and len functions.
