Zend_Form_Element_Captcha doesn't works as expected !

[SŽébastien Cramatte]

Hello,

I'm trying to create a captcha with Image.
It practically works excepts that I see the image and 2 fields ...

I'm using ZF 1.8.0

This the generated code :

<div class="field"><label for="captcha" class="required">are_you_human</label>

<img alt="" src="/share/img/captchas/631567244e675bdf5ec0abbb61b6fe58.png"/><br/>
<input type="hidden" name="captcha[id]" value="631567244e675bdf5ec0abbb61b6fe58" helper="formText" id="captcha-id">
<input type="text" name="captcha[input]" id="captcha-input" value="" helper="formText">
<input type="text" name="captcha" id="captcha" value="631567244e675bdf5ec0abbb61b6fe58"></div>

As you can see Zend_Form render a third field ... Why ????
And in my Zend_Form class I initialize the element like this

 $elt = new Zend_Form_Element_Captcha('captcha', array(
         'label' => "are_you_human",
         'captcha' => array(
         'captcha' => 'Image',
         'wordLen' => 6,
         'timeout' => 300,
         'font' => './share/fonts/verdana.ttf',
         'imgDir' => './share/img/captchas/',
         'imgUrl' => '/share/img/captchas/',
         )
        ));

  $this->addElement($elt);

What I've missed ... It's making me crazy
Thank you for you help

Regards

       'label' => "are_you_human",
       'captcha' => array(
       'captcha' => 'Image',
       'wordLen' => 6,
       'timeout' => 300,
       'font' => './share/fonts/verdana.ttf',
       'imgDir' => './share/img/captchas/',
       'imgUrl' => '/share/img/captchas/',
       )
      ));

 $this->addElement($elt);

 
Maybe there is some particular configuration of decorators that cause this, try with a Dumb captcha and fewer option to see if you get the right inputs. Zend_Form_Element_Captcha uses an internal decorator so if your forms play with decorators it can render in wrong html.

What's the best way to handle a time or date field?

At the moment, for dates I've added a pregReplace filter to the form
element to swap from dd/mm/yyyy to yyyy-mm-dd.

Then in the view scrip, I have a second filter added to swap from
yyyy-mm-dd to dd/mm/yyyy.

It works, but I'm not really happy with the code. I just noticed the
NormalizedToLocalized and LocalizedToNormalized filters, which I'm
assuming is what I should be using.

Is the cleanest way to deal with this be to create date and time
elements together with their own custom decorators that apply the
NormalizedToLocalized filter on output? I would have thought that this
is such a common use-case that there would already have been something
set up for this?

Cheers,
David

I'm aware of Matthew's articles. My question however was whether or not creating my own decorator is necessary in this case, and also whether the NormalizedToLocalized and vice versa filters are the ones I should be using. The documentation is a wee bit sparse for those particular filters.

I wouldn't say it's necessary, but it helps promote reuse. Otherwise you'll have to write that conversion in each of your view scripts that uses a date.

Hmm.. good point. I've gone ahead and done that and works well. Seems like the NormalizedToLocalized and reverse filters aren't available in ZF 1.7, so went with the pregReplace.

Is it just me or are forms really flakey? I tried adding a GreaterThan validator in my ini config, but it refused to work. When I access an element ($form->elementName->getValue()) it tells me that I'm using a method on a non-object. I tried adding it programatically and it worked fine. Weird.

Here's what I've got:

elements.event_max_per_child.type                   = "text"
elements.event_max_per_child.options.label          = "Max Interviews Per Child"
elements.event_max_per_child.options.required       = true
elements.event_max_per_child.options.filters.int.filter = int

;Adding this one works:
;elements.event_max_per_child.options.validators.notempty.validator = "NotEmpty"

;I add these and the form dies
;elements.event_max_per_child.options.validators.greaterthan.validator = "GreaterThan'
;elements.event_max_per_child.options.validators.greaterthan.options.min = 1

In my form class's init() method:

 $this->getElement('event_max_per_child')
            ->addValidator('GreaterThan', false, array('min' => 1));
           
Any idea what I'm doing wrong?

David
