The GF_Field_Number class extends the GF_Field class, also known as the Field Object. This class is responsible for determining how the Number field is rendered when the form is displayed and how its value is handled during and after form submission. If a field is a Quantity field and Number is the chosen type of quantity, then this also handles the Quantity field.

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;


The following settings are available for the field:

  • admin_label_setting
    Controls whether the “Admin Field Label” setting appears.

  • calculation_setting
    Determines whether the “Enable Calculation” setting displays. This allows a calculation to be used for the number.

  • conditional_logic_field_setting
    Controls whether the “Enable Conditional Logic” setting appears.

  • css_class_setting
    Controls whether the “Custom CSS Class” setting displays. This allows a custom css to be used for the field.

  • default_value_setting
    Controls whether the “Default Values” section displays. This allows a value to be set for the field.

  • description_setting

  • duplicate_setting
    Controls whether the “No Duplicates” setting displays within the “Rules” section. This controls whether the same value may exist more than once in the database. The “Rules” setting must be active for this to display.

  • label_setting
    Controls whether the “Field Label” setting which allows the label to be changed appears.

    Controls whether the “Placeholders” section appears. This allows placeholder text to display for the field.

  • prepopulate_field_setting
    Controls whether the “Allow field to be populated dynamically” setting appears.

  • range_setting
    Determines whether the “Range” setting displays. This allows a minimum and maximum range to be set to ensure the number entered fits within the range.

  • rules_setting
    Controls whether the “Rules” settings section displays. The “Required” option shows when this is active.

  • size_setting
    Controls whether the “Field Size” setting displays. This controls the size of the input field for fields to which it applies. The sizes are “small”, “medium”, and “large”.
