Question

This is a very simplified version of the function I am having issues with:

function example(&$form) {
     $name = $form->getName();

     foreach ($form as $sub) {
          if ($sub instanceof Form) {
               example($sub);
          }
          // need this to be the first entry of $name
          echo $name;
      }

 }

 example($this->form);

I need a way to keep the value of the first entry of $name

Answer 1

try adding another param to the function

function example(&$form, $firstFormName = null) {
    $name = $form->getName();

    if(is_null($firstFormName))
        $firstFormName = $name;

    foreach ($form as $sub) {
        if ($sub instanceof Form) {
           example($sub, $firstFormName);
        }
    }
    // need this to be the first entry of $name
    echo $name;
}

example($this->form);
