I have a problem with aligning my legends in forms, and reading the decorator documentation did not exactly make it much clear for me how i can replace the tag with a normal .
Does anyone know how this can be done?
Thanks.
EDIT
I'm very sorry, I was still thinking about label, not legend. To replace legend tag (which is generated when you're using subforms or manually add fieldset decorator to your form and call $form->setLegend('some')) with another one, you have two options.
Write your own fieldset view helper (Zend_View_Helper_Fieldset), and put it into your application helpers directory. It will force ZF to take your helper instead this one located in library folder. In that original helper you have:
// get legend
$legend = '';
if (isset($attribs['legend'])) {
$legendString = trim($attribs['legend']);
if (!empty($legendString)) {
$legend = '<legend>'
. (($escape) ? $this->view->escape($legendString) : $legendString)
. '</legend>' . PHP_EOL;
}
unset($attribs['legend']);
}
You can replace legend tag with div in your helper and it will work.
Second way to achieve that, is just add HtmlTag decorator to your Zend_Form element instance. Look here, it's great tutorial how to use decorators in ZF: http://devzone.zend.com/1240/decorators-with-zend_form/
Sorry for misleading you at the beginning :(

I have my Zend_Form, and sometimes, one of the fields should be hidden, and not seen by the user. Is there a way when I call the form in my controller, I could change one of the fields to be hidden?
Thanks

You can remove the element using:
$form->removeElement('my-element-name');
in the controller.
You could also create two forms, one overriding the other, in which the child calls $this->remove('my-element-name').
Or, you could make the form constructor accept a boolean $flag that determines whether to add the field to the form.
So, as you can see, lots of different ways to structure it.
To change that field to one of type "hidden" (i.e. <input type="hidden">) is a different thing, but I'm not sure that's what you mean/need/want.
The best solution I have for this is to add a specific class to the element when it needs to be hidden. It may not be the perfect solution, but let me explain.
First, its very difficult to switch from one element type to another in Zend Form. Your elements are actually classes. So the text is Zend_Form_Element_Text - so its not just as easy as changing the 'type' attribute.
If the element must remain on the form (so, not removing it like the answer above suggests), your only other option would be hiding it with CSS.
Try the following code when it needs to be hidden:
$element = $form->getElement('MyElement');
$newClass = trim($element->getAttrib('class') . ' hidden');
$element->setAttrib('class', $newClass);
Then, of course, create CSS for the .hidden class.
Hope this helps!
I want to add some javacsript to a Zend_Form_Element_Text .
At first I thought a decorator would be the best way to do it, but since it is just a script (the markup doesn't change) then maybe a view helper is better? or a view script?
It seems like they are all for the same purpose (regarding a form element).
The javascript I want to add is not an event (e.g. change, click, etc.). I can add it easily with headScript() but I want to make it re-usable , that's why I thought about a decorator/view helper. I'm just not clear about the difference between them.
What is the best practice in this case? advantages?
UPDATE: Seems like the best practice is to use view helpers from view scripts , so decorators would be a better fit?
Thanks.
You could create your own decorator by extending Zend_From_Decorator_Abstract and generate your snippet in it's render() method :
class My_Decorator_FieldInitializer extends Zend_Form_Decorator_Abstract {
public function render($content){
$separator = $this->getSeparator();
$element = $this->getElement();
$output = '<script>'.
//you write your js snippet here, using
//the data you have in $element if you need
.'</script>';
return $content . $separator . $output;
}
}
If you need more details, ask for it in a comment, i'll edit this answer. And I didn't test this code.
Use setAttrib function.
eg:-
$element = new Zend_Form_Element_Text('test');
$element->setAttrib('onclick', 'alert("Test")');
I'm not actually seeing where this needs to be a decorator or a view-helper or a view-script.
If I wanted to attach some client-side behavior to a form element, I'd probably set an attribute with $elt->setAttrib('class', 'someClass') or $elt->setAttrib('id', 'someId'), some hook onto which my script can attach. Then I'd add listeners/handlers to those targeted elements.
For example, for a click handler using jQuery , it would be something like:
(function($){
$(document).ready(function(){
$('.someClass').click(function(e){
// handle the event here
});
});
})(jQuery);
The benefit is that it is unobtrusive, so the markup remains clean. Hopefully, the javascript is an enhancement- not a critical part of the functionality - so it degrades gracefully.
Perhaps you mean that this javascript segment itself needs to be reusable across different element identifiers - someClass, in this example. In this case, you could simply write a view-helper that accepts the CSS class name as the parameter.
"the markup doesn't change", Yap,
but I like to add some javascript function throw ZendForm Element:
$text_f = new Zend_Form_Element_Text("text_id");
$text_f->setAttrib('OnChange', 'someFunction($(this));');
The best way is if you are working with a team, where all of you should use same code standard. For me and my team this is the code above.
I want get the follow thing working.
I've a page with a couple of text articles, each article has his own 'id' in the database. Below every article I want to make it possible to discuss about it. So I setup a discuss form witch I print with my article trough a 'foreach'.
In the form I added a Zend_Form_Element_Hidden. In the view I want to set the value of the hidden field with 'article_id', this likes me the best way to put it in the database?
In the foreach I try the follow thing but when I do this, the form is gone and I only get the element where I add the value.
My code in the view:
foreach ($this->paginator as $article):
echo $this->form->getElement('article')->setValue($article['id']);
endforeach;
I hope some one can make this a bit more clear for me :)
With kind regards,
Nicky
I am guessing you want to print the form inside the loop but only the element is being printed.
If that is your problem, the reason is because setValue() returns the element and not the form.
// Your Code
// This will only print the element and not the entire form
echo $this->form->getElement('article')->setValue($article['id']);
You will have to change your code to:
// Set the element value first
$this->form->getElement('article')->setValue($article['id']);
// Then render the form
echo $this->form;
I have a need to create a <br/> tag in the display label for a menu item generated using Zend_navigation, but don't seem to be able to find a way to do so.
My navigation item is defined in the XML config as:
<registermachine>
<label>Register your Slitter Rewinder</label>
<controller>service</controller>
<action>register</action>
<route>default</route>
</registermachine>
I want to force a tag in the output HTML between 'your' and 'slitter', such that it appears on two line as below:
Register your
Slitter Rewinder
However, I can't seem to do it. obviously using in the XML breaks parsing, and using html entities means that the lable is displayed as:
Register your <br/>Slitter Rewinder
Has anyone had experience of this that can offer advice?
Thanks in advance!
there is no such option built-in you have to use a partial
$partial = array('menu.phtml', 'default');
$this->navigation()->menu()->setPartial($partial);
echo $this->navigation()->menu()->render();
http://framework.zend.com/manual/en/zend.view.helpers.html#zend.view.helpers.initial.navigation.menu
you may also try a hack with <label><![CDATA[Menu label<br/>Second line]]></label>
I found a (hacky) solution:
I updated my navigation.xml to use {br} tokens wherever a <br/> tag is required, and then amended the base Zend/View/Helper/Navigation/Menu.php file as follows:
within htmlify function, changed
$this->view->escape($label)
to
str_replace("{br}", "<br/>", $label)
I could (and probably will) override the Zend Library Menu View Helper with my own at some point, but this at least cover it for now.
there is a escapeLabels boolean used to convert html tags and it's true by default.
You can set your navigation like this
$this->navigation()
->menu()
->escapeLabels(false)
->...

I am extremely new to Zend Framework, In registration form, i need label text in two line. For Example:- In the case First name, I need to display like below:
First
Name:
How can i implement this? Please anyone help me!!!
By default, input fields labels are being escaped by Zend_View_Helper_FormLabel. However, you can easy switch this off:
$yourTextInputElement->getDecorator('label')->setOption('escape', false);
This way you can use labels as e.g. $yourTextInputElement->setLabel('First <br/> name');.
What about this nifty solution ?

The best way is probably to use Description decorator, or subclass one of other standard ZF decorators.
Yanick's CSS solution might be a good choice too, depending what are you trying to do.
