Is it possible to validate only present fields of the form..
For example, I have a declarationForm, I give rules in the validation.yml for 3 fields : name, reference, commantary.. sometime I dont add commentary field in my builder. Anyway when I validate the form it says that commentary cannot be empty (but there is no field commentary)
Yes, but you will have to remove the NotBlank conditions from your validation.yml for the commentary field and add the requirement back into the builder whenever you include it in your FormBuilderInterface:
$builder
// ... other fields using add()
->add('commentary', 'text', array(
'required' => true,
))
;
Note however that this does indeed only add an HTML5 required attribute to both the input and label tags.
The better solution thanks to #Cerad is to add validation groups to your validation.yml for the field:
AcmeBundle\Entity\Declaration: # change to your entity class
properties:
# ...
commentary:
- NotBlank: { groups: [commentaryReq] }
And then use the Form Builder with this validation group when needed:
$form = $this->createFormBuilder($declaration, array(
'validation_groups' => array('commentaryReq'),
))
//->add(...)
;
or if you're using Form Classes:
use Symfony\Component\OptionsResolver\OptionsResolverInterface;
public function setDefaultOptions(OptionsResolverInterface $resolver)
{
$resolver->setDefaults(array(
'validation_groups' => array('commentaryReq'),
));
}
You can also specify groups based on submitted data or specify groups based on the button that was clicked if that helps.
If you want to allow empty commentary field, add nullable=true to its column definition in your entity:

Suppose to have an entity in Symfony2 that has a field bestfriend, which is a User entity selected from a list of User entities that satisfy a complex requirement.
You can render this field in a form by specifying that it is an entity field type, i.e.:
$builder->add('bestfriend', 'entity', array(
'class' => 'AcmeHelloBundle:User',
'property' => 'username',
));
This form field is rendered as a <select>, where each one of the displayed values is in the form:
<option value="user_id">user_username</option>
So, one would render the field by using the <optgroup> tags to highlight such special feature of the friends.
Following this principle, I created a field type, namely FriendType, that creates the array of choices as in this answer, which is rendered as follows:
$builder->add('bestfriend', new FriendType(...));
The FriendType class creates a <select> organized with the same <option>s but organized under <optgroup>s.
Here I come to the problem! When submitting the form, the framework recognize that the user field is not an instance of User, but it is an integer. How can I let Symfony2 understand that the passed int is the id of an entity of type User?
Here follows my solution.
Notice that it is not mentioned in the Symfony2 official docs, but it works! I exploited the fact that the entity field type is child of choice.
Hence, you can just pass the array of choices as a param.
$builder->add('bestfriend', 'entity', array(
'class' => 'AcmeHelloBundle:User',
'choices' => $this->getArrayOfEntities()
));
where the function getArrayOfEntities() is a function that fills the choice list with the friends of my friends, organized by my friends:
private function getArrayOfEntities(){
$repo = $this->em->getRepository('AcmeHelloBundle:User');
$friends = $repo->findAllFriendByComplexCriteria(...);
$list = array();
foreach($friends as $friend){
$name = $friend->getUsername();
if(count($friend->getFriends())>0){
$list[$name] = array();
foreach($friend->getFriends() as $ff){
$list[$name][$ff->getUsername()] = $ff;
}
}
}
return $list;
}
I know the example could be meaningless, but it works...
PS: You need to pass the entity manager to let it working...
I have few fields on the form like name, description, timestamp.
Now in the form I am only displaying name and description but not timestamp.
public function __construct()
{
$this->setTimestamp(new \DateTime());
}
Now in my database, it is coming as null.
Either doctrine is not executing constructor or those fields are set to null when displayed in form.
Even though I am not displaying them.
You need put the timestamp field in your FormType.
If you don't need to show it, just hide the field and set default value.
Something like that:
$builder->add('timestamp', 'hidden', array(
'data' => new \DateTime(),
));
Don't forget {{form_rest(form)}} at end of the twig template to send all hidden fields.
I have added a field on the page_node_form with the following code.
switch($form_id){
case 'page_node_form':
$form['comment_popup'] = array(
'#type' => 'select',
'#title' => t('Comments popup'),
'#options' => array('On' => 'On', 'Off' => 'Off'),
);
}
As the comment form appears on the node so I want when the comment_popup field has the value Off then the subject field should not be displayed in the comment form and when the comment_popup field has the value 'On' then the subject field should be displayed.
I have tried the following code but it did not work.
case 'comment_node_page_form':
if($form_state['comment_popup']['#value'] == 'Off') {
$form['subject']['#access']=FALSE;
}
Any one who can help me?
What you're doing can't work I'm afraid, you're setting an element in one form and then trying to read it from another form which doesn't make sense.
What you need to do is add a submit handler to the page_node_form function which saves the comment_popup value for that node to a custom table. Then in the form alter for `comment_node_page_form' you need to read in the comment_popup data for that particular node, and make the access decisions to the form elements based on that.
Hope that helps
I'm writing this question cause I have difficulties setting up default values for a _MultiCheckbox element of a Zend Framework 1.9.3.
I create Zend_Form_Element_MultiCheckbox with multiple options like this:
$multiCheckbox = new Zend_Form_Element_MultiCheckbox( 'elId',
array ( 'disableLoadDefaultDecorators' =>true ) );
$multiCheckbox ->setName( 'elId' )
->setLabel('elId')
->setRequired( false )
->setAttrib('class', 'inputtext')
->setDecorators( array( 'ViewHelper' ) )
->setMultiOptions( $options );
where the $options array is an associative array 'key' => 'value'. The field is displayed just fine and I can get all the checked values for that element.
When returning to that page I need to restore from the DB the whole list of options again and mark the checked ones. I have tried to do it like that:
$multiCheckbox ->setValue( $defaults );
where $default is array, containing elements of type 'checked_option_field_id' => true(eg. array( '1222' => true, '1443' => true ) ). That action checks ALL the checkboxes and not only the once I need and I have passed to the setValue() method.
I have tried to pass just an array containing elements of type 'checked_option_field_id', (eg. array( '1222', '1443' ) )but that also doesn't work - NONE of the checkboxes is checked.
I have used the form setDefaults() method with those two kinds of arrays, but the results are same - as this method uses again setValue() for each element.
MultiCheckbox element is rendered like that ( result when try to set checked value for only one option ):
<label for="elId-1222"><input type="checkbox" name="elId[]" id="elId-1222" value="1222" checked="checked" class="inputtext">BoRoom </label><br />
<label for="elId-1443"><input type="checkbox" name="elId[]" id="elId-1443" value="1443" checked="checked" class="inputtext">BoRoom Eng2 </label><br/>
That element populates the checked option values in the elId[] array. That is the element name.
setDefaults() form method gets all form elements by name and commit their default values by calling setDefault() form method and after that setValue() element method. So my multicheckbox element has name elId ( it does not get all the element options one by one ) and set default values for all options instead of just the given in the array.
That is how I see it and I can't find solution how to set default values only for some of the options of a multicheckbox element.
Chris is correct that setValue() expects an array of values to be 'checked' (not an array of bool values keyed by your option IDs).
If you are looking for the logic behind the form generation, don't look at the Zend_Form_Element object (or the many extended elements from it), look at the Zend_View_Helper objects. Specifically the Zend_View_Helper_FormRadio object.
When generating the HTML the options array is looped, then the value is checked against the value array - the array passed to setValue(), using in_array().
From Zend_View_Helper_FormRadio line: 150
// is it checked?
$checked = '';
if (in_array($opt_value, $value)) {
$checked = ' checked="checked"';
}
Not sure what that's not working for you, but if you're passing:
$element->setMultiOptions(array('1111' => 'Some Label',
'2222' 'Some Other Label',
'3333', 'Not Selected Label'));
$element->setValue(array('1111','2222');
It should work. Maybe if you could include some code it would be easier to see what's going on?
The setValue() expects a array with those values that need to be checked, in this case for example you need to pass a array with values 1222, 1443 for them to be marked as checked.
You need to serialize the checkbox value before insert in database. To show the database value selected again you have to unserialize the data to show.
