GF_Field_SelectIntroductionSettings and PropertiesSettingsPropertiesSource Code
Introduction
The GF_Field_Select class extends the GF_Field class, also known as the Field Object. This class is responsible for determining how the Drop Down field is rendered when the form is displayed and how its value is handled during and after form submission. This class also handles the rendering of the Product, Product Option, Quantity, Shipping fields when they are a drop down.
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 page.
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:
12345//get the field$field = GFFormsModel::get_field( $form, 1 ); //get the admin label$admin_label = $field->adminLabel;
