Zend Form Radio Default Checked

Question

I have the next radio button group:

$enabled = $this->createElement('radio', 'enabled')
                ->setLabel('Enabled')
                ->setMultiOptions(array('1'=>'yes', '0'=>'no'))
                ->setValue($rank_values['enabled'])
                ->setAttrib('id', 'enabled')
                ->setAttrib('class', $action . '_enabled')
                ->setSeparator('');

How can I set a checked radio? Now, when I open my script, there are not selected radio. I want to select 'yes'. How?

Thank you.

Solution 1

it is much more easier :)

$enabled = $this->createElement('radio', 'enabled')
                ->setLabel('Enabled')
                ->setMultiOptions(array('1'=>'yes', '0'=>'no'))
                ->setValue($rank_values['enabled'])
                ->setAttrib('id', 'enabled')
                ->setAttrib('class', $action . '_enabled')
                ->setSeparator('')
                ->setValue("1");

In case somebody wonders, I'm using the array notation to declare all my elements in my forms and in zend framework 2 to have a default option selected in a radio button you have to add the attribute value and make it have the key of the value_options you want to be selected by default:

// Inside your constructor or init method for your form //
$this->add(
        [
            'type'       => 'Radio',
            'name'       => 'some_radio',
            'options'    => [
                'value_options' => [
                    'opt1' => 'Radio option 1',
                    'opt2' => 'Radio option 2'
                ]
            ],
            'attributes' => [
                'value' => 'opt1' // This set the opt 1 as selected when form is rendered
            ]
        ]
    );

I found some examples a little confusing because they were using numeric keys in the value options (0, 1) so when I saw 'value' => 1 it wasn't obvious for me that this was the key in the value_options array. Hope this helps someone.

Use this:

->setAttrib("checked","checked")

So that your complete code looks like this:

$enabled = $this->createElement('radio', 'enabled')
            ->setLabel('Enabled')
            ->setMultiOptions(array('0'=>'no', '1'=>'yes'))
            ->setAttrib("checked","checked")
            ->setValue($rank_values['enabled'])
            ->setAttrib('id', 'enabled')
            ->setAttrib('class', $action . '_enabled')
            ->setSeparator('');

[EDIT] Using setValue:

You can alternatively use this:

->setValue('1')

This will check the option represented by value 1 which is yes.

According to the manual, you would do it this way if you were to use array notation: link to manual

 $this->add(
        [
            'name'       => 'someRadioMethod',
            'type'       => 'radio',
            'options' => [
                'label' => 'Some descriptive label',
                'value_options' => [
                    [
                        'value' => '1',
                        'label' => 'Label for 1',
                        'selected' => true,

                    ],
                    [
                        'value' => '2',
                        'label' => 'Label for 2',
                        'selected' => false,

                    ]
                ],
            ],
        ]
    );

I found that if you have a filter set then ->setvalue('X') does not work.

I removed ->addFilter('StringToLower')
and added ->setSeparator('')->setValue('N');

Worked a treat
