Here's a simple XML config file I used:
<?xml version="1.0"?>
<configdata>
<form>
<elements>
<keywords>
<type>text</type>
<options>
<name>keywords</name>
<label>Keywords</label>
<filters>
<stripTags>
<filter>StripTags</filter>
<options>
<tagsAllowed>
<tag><![CDATA[<a>]]></tag>
<tag><![CDATA[<p>]]></tag>
</tagsAllowed>
<attributesAllowed>class</attributesAllowed>
<commentsAllowed>1</commentsAllowed>
</options>
</stripTags>
</filters>
</options>
</keywords>
</elements>
</form>
</configdata>
I then did the following script:
$config = new Zend_Config_Xml(dirname(__FILE__) . '/form.xml', 'form');
$form = new Zend_Form($config);
$filters = $form->keywords->getFilters();
var_export($filters);
and I get the following output:
array (
'Zend_Filter_StripTags' =>
Zend_Filter_StripTags::__set_state(array(
'commentsAllowed' => true,
'_tagsAllowed' =>
array (
'tag' =>
array (
'<a>' => NULL,
'<p>' => NULL,
),
),
'_attributesAllowed' =>
array (
'class' => NULL,
),
)),
)
As you can see, the filter is being correctly setup.
One thing to note when using configuration: the options you pass are
passed IN ORDER to the constructor of the filter -- you can't skip
options, nor can you pass them out-of-order -- which is why the below
config does not work. It's missing the first argument (corresponding to
'tagsAllowed'), and it's got commentsAllowed and attributesAllowed in
the wrong order.
