DEVELOPING COLDFUSION 9 APPLICATIONS 104 The CFML Programming Language Code Description Set default values of all form fields so that they exist the first time this page is displayed and can be tested. Please fill out the form. Test the value of the firstname field. This field is required. The test is False the first time the page displays. If no data exists in the Form.firstname variable, display a message requesting the user to fill the form. employee=StructNew(); employee.firstname = Form.firstname; employee.lastname = Form.lastname; employee.email = Form.email; employee.phone = Form.phone; employee.department = Form.department; If Form.firstname contains text, the user submitted the form. Use CFScript to create a structure named employee and fill it with the form field data. Then display the contents of the structure. First name is #StructFind(employee, "firstname")# Last name is #StructFind(employee, "lastname")# EMail is #StructFind(employee, "email")# Phone is #StructFind(employee, "phone")# Department is #StructFind(employee, "department")# Call the cf_addemployee custom tag and pass it a copy of the employee structure in the empinfo attribute. The duplicate function ensures that the custom tag gets a copy of the employee structure, not the original. Although this is not necessary in this example, it is good practice because it prevents the custom tag from modifying the calling contents of the structure in the calling page. First Name:  Last Name:  EMail:  Phone:  Department:  The data form. When the user clicks OK, the form posts the data to this ColdFusion page. Example file addemployee.cfm The following file is an example of a custom tag used to add employees. Employee information is passed through the employee structure (the empinfo attribute). For databases that do not support automatic key generation, also add the Emp_ID. Last updated 1/20/2012
