Zend_Filter_Input and arrays from form elements

Hello,

This may be obvious to everyone else but it took me a little bit of figuring out and playing with code to find the answer. As you may know, you can send PHP arrays from forms e.g.

Code:

<input type="text" name="test[0]" value="something" />
<input type="text" name="test[1]" value="something else" />
...

Which, if submitted via post should give you something like:

PHP Code:


			
$_POST['test'][0]; // 'something'

$_POST['test'][1]; // 'something else'

...

What isn't totally clear from the ZF docs on Zend_Filter_Input is how to filter and validate fields such as these.

Fortunately, I guess the ZF guys have actually thought of this and you just set a filter and validator rule for the whole array and then access it as normal e.g.

PHP Code:


			
// Filter rules

$filters = array('test' => new Zend_Filter_Alpha());

// Validator rules

$validators = array('test' => new Zend_Validate_Alpha());



$input = new Zend_Filter_Input($filters, $validators, $_POST);



$input->test[0]; // 'something'

$input->test[1]; // 'something else'

Just thought I'd share anyway

Cheers.
