Question

This code does not function as expected:

// $field contains the name of a subclass of WMSInput.
$fieldClone = clone $field;

echo $fieldClone->getInputName();

// Method on abstract WMSInput superclass.
$fieldClone->setInputName( 'name' );

echo $fieldClone->getInputName();

The WMSInput class:

abstract class WMSInput {
  private $inputName;

  public function setInputName( $inputName ) {
    $this->inputName = $inputName;
  }
}

There are no PHP errors (error reporting is set to E_ALL).

Actual Results

email
email

Expected Results

email
name

Any ideas?

On my test site it worked ok.

You haven’t copied method getInputName in your example. I’d start searching in there. Maybe you return not the desired variable?

My test code was:

<?php

abstract class WMSInput {
  private $inputName;

  public function setInputName( $inputName ) {
    $this->inputName = $inputName;
  }

  public function getInputName() {
    return $this->inputName;
  }
}

class Test extends WMSInput {
}

$field = new Test();

$field->setInputName('email');

// $field contains the name of a subclass of WMSInput.
$fieldClone = clone $field;

echo $fieldClone->getInputName();

// Method on abstract WMSInput superclass.
$fieldClone->setInputName( 'name' );

echo $fieldClone->getInputName();

Output:

emailname

which is correct.
