Custom field code used in single article view override.

gistfile1.txt

// loop through all the fields attached to the article.

foreach ($this->item->jcfields as $field) :
	// There is the $field->params->get('your_parameter_here');
	// If you have a select field and would like to retrieve the "text" values of all the options
	// You can get these by using the code below. Depending on the field you replace 'options' with whatever parameter you want to fetch.
	// To view all params available you can do a 'var_dump($field->fieldparams);' to display the params. 
  // Examples when you would want to use this: Use both text and value of a select list (by default you only have a comma seperated string of the selected texts in the $field->value, and an array of values in $field->rawvalue).
	// Or if you have a repeatable field you can retrieve the field names to make the override more "dynamic". 
        
  $fieldparams = $field->fieldparams->get('options');
	
	// There is also the $field->params->get('your_parameter_here');
	// With this you can for instance retrieve render_class parameter. This i've used before to add a class in certain places.
	
	$params = $field->params->get('render_class');
