Check value from Gravity Forms API - php

Question

I am creating a custom Gravity Forms add-on and it appears to work so far. The settings are showing and saving as expected.
Here's what I have:
public function plugin_settings_fields() {
return array(
array(
'title' => esc_html__( 'Animal Types', 'animaltypes' ),
'fields' => array(
array(
'name' => 'gravity_forms_animal_types',
'type' => 'checkbox',
'label' => esc_html__( 'Animal Types', 'animaltypes' ),
'choices' => array(
array(
'label' => esc_html__( 'Cat', 'animaltypes' ),
'name' => 'option_cat',
'default_value' => 0,
),
array(
'label' => esc_html__( 'Dogs', 'animaltypes' ),
'name' => 'option_dog',
'default_value' => 0,
)
)
),
)
)
);
}
But what I can't figure out is how to check, for example, if option_cat has been set so that I can then run a custom function if it is.
So essentially (and I know the below code is not correct) something like this:
if(option_cat == true) {
my_cat_function();
}

Answer 1

In gravity forms when you create a new addon you provide a slug for that addon. Gravity forms save that settings with the help of that slug.
So if you want to get that settings you can use below code.
$settings = get_option('gravityformsaddon_slugname__settings');
$option = rgar( $settings, 'gravity_forms_animal_types' );
In options you can get selection of your settings, and if you want to one selection at a time you must use radio button instead of checkbox.

It was quite simple after all.
$options = get_option('gravityformsaddon_animaltypes_settings');
$cat = $options['option_cat'];
if($cat) {
my_cat_function();
}
