ZF-12119: Zend_Form_Element::filterName() removes characters which may be legal (e.g. periods, colons)

Issue Type: Bug Created: 2012-03-25T14:28:05.000+0000 Last Updated: 2013-03-13T20:55:21.000+0000 Status: Open Fix version(s): - Next Mini Release ()

According to W3C, form ID and NAME tokens must begin with a letter ([A-Za-z]) and may be followed by any number of letters, digits ([0-9]), hyphens ("-"), underscores ("_"), colons (":"), and periods ("."). -

Trying to create a form element with the name makes it foobar - e.g.

<pre class="literal">
require_once 'Zend/Form/Element/Hidden.php';

$foo = new Zend_Form_Element_Hidden(array('name' => ''));
echo $foo->getName(); // foobar

Hi Eddo, thanks for reporting!

The patch must include:

  • an update for Zend_Form::filterName() -- names must begin with a letter ([A-Za-z]) -- hyphens ("-"), underscores ("_"), colons (":") and periods (".") must be accepted
  • updates for the unit tests: -- Zend_Form_FormTest::testSetNameNormalizesValueToContainOnlyValidVariableCharacters() -- Zend_Form_FormTest::testArrayToWhichElementsBelongCanConsistOfValidVariableCharsOnly()
  • a new unit test for the first character in the name

Have you found an issue?
