Array in module settings

[Rudy]

Hi,

I am writing a custom module that requires storing array of settings in the module config/settings.

Is there a built-in fieldtype that allows me to store settings in an array (sort of like Repeater)?

I tried using InputfieldAceExtended and InputfieldTextarea to store JSON array. Both times, my data was stored in the module settings (in the database) but upon reload, that information was not retrieved.

Thanks
Rudy

Hi Rudy,

 

Storing a JSON array in a TextArea should works as expected without doing anything than saving the field in a standard fashion. 

 

protected static function getDefaultData()
{
    	return array(
        	'json_config'  => ''
    	);
}

public static function getModuleConfigInputfields(array $data) {

        $data = array_merge(self::getDefaultData(), $data);
        $modules = wire('modules');

        $fields = new InputfieldWrapper();

        $field = $modules->get("InputfieldTextarea");
        $field->label = __('JSON Config');
        $field->attr('name+id', 'json_config');
        $field->attr('value', $data['json_config']);
        $fields->append($field);

		return $fields;
}

The fact that the data is being stored in the database as json is good. On retrieval you need to explicitly tell PW what/where to put the data. For example, a textarea field only has one 'value'. In your config screen there a several fields which should be populated with bits of the json data. I think you're one step away. Retrieve the json then assign the individual bits to your module config inputfields

@flydev Thanks! I was missing this bit

$field->attr('value', $data['json_config']);

Cheers!
