Inputfield::set() method

Set a property or attribute to the Inputfield

  • Use this for setting properties like parent, collapsed, required, columnWidth, etc.
  • You can also set properties directly via $inputfield->property = $value.
  • If setting an attribute (like name, id, etc.) this will work, but it is preferable to use the Inputfield::attr() method.
  • If setting any kind of "class" it is preferable to use the Inputfield::addClass() method.


// Set a value for a property
$item->set('foo', 'bar');

// Set a property value directly
$item->foo = 'bar';

// Set a property using array access
$item['foo'] = 'bar';


$inputfield = $inputfield->set(string $key, mixed $value);
