I'm bit confused about the meaning of this line:

$show_title = Ninja_Forms()->form( $form_id )->get_setting( 'show_title' );

Is -> available in PHP, or it used only within WordPress.

NO -> is not wordpress specific, it is object operator in php.

When you want to call a method of an instance then you call the method with ->

Class SomeClass{

  function example(){
   return 'This is an example function'

$obj = new SomeClass();
$obj->example(); // we are calling example function with -> operator

Additional Info: there is one more operator :: which is used to call for static methods of a class.

  • Also show an example the process of accessing this $show_title = Ninja_Forms()->form( $form_id )->get_setting( 'show_title' );

  • Ninja_Forms()->form( $form_id )->get_setting( 'show_title' ); Ninja_Forms() is a function which returns an object instance. so calling an method of it is form($form_id) and now this too returns an object instance. finally calling the method get_setting('show_title');
