Custom formatting of non-editable fields

[Jonathan Lahijani]

I have a decimal field that has been set to non-editable.  I want to format the value so it's nicer when editing a page.  For example, instead of showing 123456, I want to format it to show $123,456.00

What is the proper way to hook into it and modify the rendered value?

FieldtypeDecimal uses InputfieldFloat as its inputfield, and it's the renderValue() method that determines what is shown when a field is not editable.

So you could do this:

$wire->addHookAfter('InputfieldFloat::renderValue', function(HookEvent $event) {
	/** @var InputfieldFloat $inputfield */
	$inputfield = $event->object;
	$field = $inputfield->hasField;
	if($field && $field->name === 'your_field_name') {
		$event->return = '$' . number_format((float) $inputfield->value, 2);
	}
});
