ZF-7048: Zend_View_Helper_FormRadio creates invalid labels and id's

Issue Type: Bug Created: 2009-06-19T03:25:12.000+0000 Last Updated: 2011-07-08T07:16:17.000+0000 Status: Open Fix version(s): Reporter: Christiaan Kras (htbaa) Assignee: Matthew Weier O'Phinney (matthew) Tags: - Zend_View

There's a problem when passing an array to Zend_View_Helper_FormRadio that contains positive and negative values,

This array for example

<pre class="highlight">
    $opties = array('1'     => 'Some option',
                    '-1'    => 'Another option');

Will generate 2 radio buttons with the id "myname-1". Duplicate id's are not allowed and it also disables you from choosing the desired option. When you choose 'Another option' by clicking the label the radio button for 'Some option' will be selected.

Although we can't quite match on the full list of valid characters since PHP's regular expressions can't match Unicode character ranges, creating and using this filter instead of the Alnum filter should work for all cases when only 7-bit characters are used in IDs (which should be pretty much always):

<pre class="highlight">

 * @see Zend_Filter_Interface
require_once 'Zend/Filter/Interface.php';

class Zend_Filter_XmlName implements Zend_Filter_Interface
     * Defined by Zend_Filter_Interface
     * Returns the string $value, removing all characters not valid in an XML
     * name as defined by <a href=""></a>.
     * Note that this currently only allows 7-bit-safe characters since
     * preg_replace does not support pattern matching on unicode character
     * ranges.
     * @param  string $value
     * @return string
    public function filter($value)
        $value = preg_replace('/[^A-Za-z0-9:_.-]/', '', (string) $value);
        return substr($value, strspn($value, '0123456789.-'));

Patch against 1.8.4PL1:

There are probably other cases where this new filter should be used as well but I am not going to go looking for them right now. :)
