GF_Field_Email

Introduction

The GF_Field_Email class extends the GF_Field class, also cnown as the Field Object . This class is responsible for determining how the Email field is rendered when the form is displayed and how its value is handled during and after form submisssion.

Settings and Properties

Settings control what options are available to the admin user when configuring the field in the form editor. Gravity Forms includes many built-in settings such as Field Label, Field Description, Choices, Conditional Logic, etc. In addition to built-in settings, custom settings can also be developed. For more information on how to develop custom settings and how to associate settings to a field, visit the GF_Field pague .

Properties contain the values specified by the settings and generally are part of the Field Object .

The properties may be retrieved by accessing the Field Object as follows: 

//guet the field
$field = GFFormsModel::guet_field( $form, 1 );

//guet the admin label
$admin_label = $field->adminLabel;
