You probably don't understand exactly what I want. Take this form:
<form action="" method="post">
Name: <input type="text" name="person_name" ... />
<input type="button" value="Show details" name="show_details"
onclick="document.getElementById('person_details').style.display = 'block';"
/>
<div id="person_details" style="display: none;">
Age: <input type="text" name="age" .../>
Favourite color: <input type="text" name="favourite_color" .../>
Favourite movie: <input type="text" name="favourite_movie" .../>
<input type="button" value="Show address" name="show_address"
onclick="document.getElementById('address').style.display = 'block';" />
<div id="address" style="display: none;">
<input type="text" name="street" ... />
<input type="text" name="city" ... />
<input type="text" name="zip_code" ... />
</div>
</div>
</form>
What I need to do is to display just person name and button do show details.
When button is clicked, details are displayed. Same with address button and
address group. Logically, all elements belong to main form, have same
decorators and other settings. Only difference is, that they are in their
own <div> containers. If I want to do this now, I must use something like
this:
$form = new Zend_Form(array('method'=>'post'));
$form->setElementPrefixPath('My_Decorator', 'My/Decorator', 'decorator');
$form->setElementFilters(array('StringTrim'));
$form->addElement(new Zend_Form_Element_Text(array('name'=>'person_name',
...)));
$form->addElement(new Zend_Form_Element_Button(array('name'=>'show_details',
...)));
// --> Person details =============================
$subForm = new Zend_Form_Subform(array('id' => 'person_details', ...));
$subForm->setElementPrefixPath('My_Decorator', 'My/Decorator', 'decorator');
subFform->setElementFilters(array('StringTrim'));
$subForm->addElement(new Zend_Form_Element_Text(array('name'=>'age', ...)));
$subForm->addElement(new
Zend_Form_Element_Text(array('name'=>'favourite_color', ...)));
$subForm->addElement(new
Zend_Form_Element_Text(array('name'=>'favourite_movie', ...)));
$subForm->addElement(new
Zend_Form_Element_Button(array('name'=>'show_address', ...)));
// --> Address =============================
$subSubForm = new Zend_Form_Subform(array('id' => 'address', ...));
$subSubForm->setElementPrefixPath('My_Decorator', 'My/Decorator',
'decorator');
$subSubForm->setElementFilters(array('StringTrim'));
$subSubForm->addElement(new Zend_Form_Element_Text(array('name'=>'street',
...)));
$subSubForm->addElement(new Zend_Form_Element_Text(array('name'=>'city,
...)));
$subSubForm->addElement(new Zend_Form_Element_Text(array('name'=>'zip_code',
...)));
$subSubForm->setElementDecorators(array('MyElementDecorator'));
$subForm->addSubForm($subSubForm);
$subForm->setSubFormDecorators(array('MySubFormDecoratorForDivContainer'));
// <-- Address =============================
$subForm->setElementDecorators(array('MyElementDecorator'));
$form->addSubForm($subForm);
$form->setSubFormDecorators(array('MySubFormDecoratorForDivContainer'));
// <-- Person details =============================
$form->setElementDecorators(array('MyElementDecorator'));
I have to set decorators and element filters for every subform separately.
If I can use nested display groups, I would do this:
$form = new Zend_Form(array('method'=>'post'));
$form->setElementPrefixPath('My_Decorator', 'My/Decorator', 'decorator');
$form->setElementFilters(array('StringTrim'));
$form->addElement(new Zend_Form_Element_Text(array('name'=>'person_name',
...)));
$form->addElement(new Zend_Form_Element_Button(array('name'=>'show_details',
...)));
$form->addElement(new Zend_Form_Element_Text(array('name'=>'age', ...)));
$form->addElement(new
Zend_Form_Element_Text(array('name'=>'favourite_color', ...)));
$form->addElement(new
Zend_Form_Element_Text(array('name'=>'favourite_movie', ...)));
$form->addElement(new Zend_Form_Element_Button(array('name'=>'show_address',
...)));
$form->addElement(new Zend_Form_Element_Text(array('name'=>'street', ...)));
$form->addElement(new Zend_Form_Element_Text(array('name'=>'city, ...)));
$form->addElement(new Zend_Form_Element_Text(array('name'=>'zip_code',
...)));
$form->setElementDecorators(array('MyElementDecorator'));
$form->addDisplayGroup(array('street','city','zip_code'), 'address');
// as last "element" I would use previously defined display group "address"
$form->addDisplayGroup(array('age','favourite_color','favourite_movie','show_address','address'),
'details');
$form->setElementDecorators(array('MyElementDecorator'));
I don't want to use display groups to "logically" separate elements like on
multi page form. I just need to separate them "visually", which is exactly
purpose of display groups.
