The GF_Field_CreditCard class extends the GF_Field class, also known as the Field Object. This class is responsible for determining how the Credit Card field is rendered when the form is displayed and how its value is handled during and after form submission.

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 credit card style
$card_style = $field->creditCardStyle;


The following settings are available for the field:

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

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

  • credit_card_setting
    Controls whether the “Supported Credit Cards” section displays. This allows specific available credit cards to be selected for use.

  • credit_card_style_setting
    Controls whether the “Card Icon Style” section displays. This allows the style of the credit card icons to be set to Standard or 3D.

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

  • description_setting
    Controls whether the “Description” setting appears. This allows a description for the field to be displayed.

  • error_message_setting
    Controls whether the “Custom Validation Message” setting which allows a custom message to be used appears.

  • force_ssl_field_setting
    Controls whether the “Force SSL” section displays. This allows the page to be forced to be secure when this field exists.

  • input_placeholders_setting
    For complex fields like the credit card, name, time, and address fields, this controls whether the “Placeholders” section will appear which lets you set placeholder text for the individual components of the field. When it is not a complex field, the “placeholder_setting” controls the display of this section.

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

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

  • sub_labels_setting
    If a field has sub-labels, controls whether the setting to set them appears.

  • sub_label_placement_setting
    If a field has sub-labels, controls whether the “Sub-Label Placement” setting appears.
