bookmark_borderGF_Field_Textarea

Introduction

The GF_Field_Textarea class extends the GF_Field class, also known as the Field Object. This class is responsible for determining how the Paragraph Text (textarea) 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 admin label
$admin_label = $field->adminLabel;

Settings

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.

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

  • default_value_textarea_setting
    Controls whether the “Default Value” setting displays. This allows default text to be shown in the textarea. If this text is not changed, it will be submitted with the form.

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

  • 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.

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

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

  • placeholder_textarea_setting
    Controls whether the “Placeholder” setting displays. This allows a hint to be provided as to what should be entered into the field. This text is not submitted with the form. If the Rich Text Editor is being used, this setting cannot be used.

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

  • rich_text_editor_setting
    Controls whether the “Use the Rich Text Editor” setting displays. If checked, the rich text editor provides an interface which allows advanced editing/formatting capabilities to the field.

  • 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”.

  • visibility_setting
