Introduction
The GF_Field_Product class extends the GF_Field class, also known as the Field Object. This class is responsible for handling the Product field. Because Product fields are either a Single Product, Drop Down, Radio Button, User Defined Price, Hidden or Calculation, this class only adds some settings and sets the title for the field in the editor. The rendering of the Product field is handled by the class associated with its sub-type. The field 「type」 property will be set to product. Depending on the product field chosen, the field 「inputType」 property will be *singleproduct**, 「select」, 「radio」, 「price」, 「hiddenproduct」, or 「calculation」.
For more details about rendering the Option field, check out the articles below:
Calculation – GF_Field_Calculation class
Drop Down – GF_Field_Select class
Hidden Product – GF_Field_Hiddenproduct class
Radio Buttons – GF_Field_Radio class
Single Product – GF_Field_Singleproduct class
User Defined Price – GF_Field_Price class
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:
//get the field
$field = GFFormsModel::get_field( $form, 1 );
//get the admin label
$admin_label = $field->adminLabel;
