PHP PodsForm::value方法代码示例

 /**
  * Return the value for a field.
  *
  * If you are getting a field for output in a theme, most of the time you will want to use display() instead.
  *
  * This function will return arrays for relationship and file fields.
  *
  * @param string|array $name The field name, or an associative array of parameters
  * @param boolean $single (optional) For tableless fields, to return the whole array or the just the first item, or an associative array of parameters
  * @param boolean $raw (optional) Whether to return the raw value, or to run through the field type's display method, or an associative array of parameters
  *
  * @return mixed|null Value returned depends on the field type, null if the field doesn't exist, false if no value returned for tableless fields
  * @since 2.0
  * @link http://pods.io/docs/field/
