func option of dependent field

kpjpowers · July 2016

Hi could it be possible to give me an example of the func option on a dependent field as im struggling to see how this works or what is sent to it. What im trying to do is get the dependent field to return a template or block containing a form which contains fields from another table these values will then be saved as a serialized field. i will be building up the template based on the id of the dependent field id.

The "func" parameter is just a callable function and uses the PHP call_user_func. So you need to create a function or a class with method (which would be an array of array($myclass, 'method')) to do the rendering of your field. The function gets the array of parameters you passed to the dependent field.


// A function perhaps in you fuel/application/helpers/my_helper.php
function my_func($params)
{
    // your custom field code goes here
}


// Then in your form code
$fields['myfield'] = array('type' => 'dependent', 'func' => 'my_func');

However, what it sounds like you are wanting to do is similar to using a "block" field that uses block layouts that perhaps contains a "template" field type:
