                    [4] => Athletics
                )

        )

)

I can output the value by using

foreach ($item->jcfields as $field) {
   echo $field->value;
}

But how can I output the options 1 by 1. Then I can style individual items

Answer 1

I haven't tested this so I could be wrong. But if I rightly remember, a protected object cannot be retrieved by $field->fieldparams->options. Instead, you'll need to use:

$options = $field->fieldparams->get('options');

foreach ($options as $option)
{
    echo $option->name;
    echo $option->value;
}

Again, I haven't tested this and have a feeling it might return a PHP error, but thought I'd give it a shot.

Answer 2

The field options are a registry object so if you've already got the field you can grab all the options with something like:

$field_options = $field->fieldparams->toArray();

print_r that and you'll see the structure it provides which you can then just foreach through.
