Multiple Checkbox render

I'm using radio/checkbox by this way:

class ExampleForm extends Form {
        …
        $group = new Check('group', array(
            'name' => 'group[]',
        ));
        $this->add($group);
        …
}

And template:

<label class="radio-inline radio-primary">
    {{ form.render('group', {'value':'10'}) }}
    {{ _('Customer') }}
</label>
<label class="radio-inline radio-primary">
    {{ form.render('group', {'value':'01'}) }}
    {{ _('Supplier') }}
</label>

And could you tell me how do you check values after a $_POST but on isValid = false. Like i said before, if my two fields are required, and if i check only one, after post i want to display form error, but keeping the checked box ?

Ok, you can do it this way:

class ExampleForm extends Form {
        …
        $group1 = new Check('group1', array(
            'name' => 'group[]',
            'value' => '1'
        ));
        $group1->addValidator(new PresenceOf(array(
            'message' => 'Group 1 is required'
        )));
        $this->add($group1);

        $group2 = new Check('group2', array(
            'name' => 'group[]',
            'value' => '2'
        ));
        $group2->addValidator(new PresenceOf(array(
            'message' => 'Group 2 is required'
        )));
        $this->add($group2);
        …
}

Template:

<label class="radio-inline radio-primary">
    {{ form.render('group1') }}
    {{ _('Customer') }}
</label>
<label class="radio-inline radio-primary">
    {{ form.render('group2') }}
    {{ _('Supplier') }}
</label>

Ok, but i guess we misunderstood on the validation part. Currently, if i use your solution, this is what i get :

But as you can see, even if the two fields are required, field one after post is not checked. Actually i would like this result (i've edit the html code to produce the screen) :

Thanks,

Okey, I check this on real form and I see that the problem is name of Checkbox (<input name="group[]">). When I remove name parameter validation works and form remeber state:

        $group1 = new Check('group1', array(
            //'name' => 'group[]',
            'value' => '1'
        ));
        $group1->addValidator(new PresenceOf(array(
            'message' => 'Group 1 is required'
        )));
        $this->add($group1);

        $group2 = new Check('group2', array(
            //'name' => 'group[]',
            'value' => '2'
        ));
        $group2->addValidator(new PresenceOf(array(
            'message' => 'Group 2 is required'
        )));
        $this->add($group2);

I think that is to do. Maybe custom validator is needed.

I understand the solution, but this is not the right behavior... I would like an array as a name to loop after isValid()... But maybe there's no solution for the moment on Phalcon. Someone of the dev team can maybe bring more informations ? Or example ?

Anyway thanks Marcin for your support.

try this

$values = array(1,2,3,4,5,6);
$group; 
for($i=0; $i<count($values);$i++){
        $group = new Check("group".$i,array(
            "name" => "group[]",
            "value" => $values[$i]
        ));
        $this->add($group);
    }

Have you tried using session variables such that in the checkbox the value whether checked or unchecked are rendered through initialized boolean variables which can be re-assigned based on the conditions you want met.

This can also be accomplished by using initalize function in your controller which can be changed inside your action based on whether the condition you want is met or not.
