how to set up a zend multiCheckbox form field with the checkboxes checked? - zend-framework

Question

i have this form:
$this->addElement (
'multiCheckbox', 'servers2',
array (
'checkedValue' => '0',
'multiOptions' => array(
'11.com' => '.com',
'12.com' => '12.com',
'16.com' => '16.com',
'3.com' => '17.com'
)
));
the problem is that the checkedValue doesn't work for this setup, it does for a simple checkbox. I've also tried 'checkedValues' => array('1','0'), singular or plural,
but no end in sight.
any ideas?
THanks

Answer 1

To mark certain checkboxes as checked, try this:
$multiCheckElement->setValue(array('11.com', '3.com'));
// or
$this->addElement (
'multiCheckbox', 'servers2',
array (
'value' => array('11.com', '3.com'), // select these 2 values
'multiOptions' => array(
'11.com' => '.com',
'12.com' => '12.com',
'16.com' => '16.com',
'3.com' => '17.com'
)
)
);

ZF2 will require you to use value_options;
$form->add(
array(
'name' => 'servers2',
'type' => \Zend\Form\Element\MultiCheckbox::class,
'attributes' => array(
'id' => 'servers2',
'class' => 'form-control',
),
'options' => array(
'label' => 'Servers 2',
'column-size' => 'sm-10',
'label_attributes' => array('class' => 'col-sm-2'),
'twb-layout' => 'horizontal',
'value_options' => array(
'11.com' => '.com',
'12.com' => '12.com',
'16.com' => '16.com',
'3.com' => '17.com'
)
),
)
);

Answer 3

To specify the checked options, as seen at
use the 'selected' => true attribute:
$options = array(
array(
'value' => '0',
'label' => 'Apple',
'selected' => false,
'disabled' => false,
'attributes' => array(
'id' => 'apple_option',
'data-fruit' => 'apple',
),
'label_attributes' => array(
'id' => 'apple_label',
),
),
array(
'value' => '1',
'label' => 'Orange',
'selected' => true,
),
array(
'value' => '2',
'label' => 'Lemon',
),
);
