If the checkbox is selected, does the variable take the value 1, and if not selected the value 0?
$builder
->add('happy', 'checkbox', array(
'label' => 'Are you happy?',
'data' => false,
));
In this link, it is not clear to me:
The value that's actually used as the value for the checkbox or radio button. This does not affect the value that's set on your object.

Thanks for the answers!
Try this,
$builder
->add('happy', 'checkbox', array(
'label'=>'Are you happy?',
'data'=>false,
'attr' => array('checked' => 'checked', 'value' => '1')
));
You mean the return value on form submission? Going by the linked page, it looks like it should return a boolean:
if the box is checked -> the field will be set to true;
if the box is unchecked -> the value will be set to false.
To be sure, you could always try dumping out the result of
$form->getData();

i am building a plugin and i want to add some settings which rely on checkboxes. if the user checks the checkbox how to know. i know how to get data from checkbox in php but got stuck in wordpress. Because we have no option to add name attribute to the checkbox. for example, i am adding a checkbox in customizer.
$wp_customize->add_setting('ion', array(
'sanitize_callback' => 'ion_checkbox'
));
$wp_customize->add_control(new WP_Customize_Control($wp_customize, 'ion', array(
'label' => 'Check',
'type' => 'checkbox',
'section' => 'search_submit_section',
'settings' => 'ion'
)));
As we see there is no option to add name attribute how we will know whether user has checked the checkbox or not. I hope you understand my question.
Thanks in advance
with ($wp_customize, 'ion', array.... the ID is ion you can get the value with
$ion_checkbox_checked = get_theme_mod('ion') ? true : false;
if the checkbox checked get_theme_mod('ion') will return 1 else 0
I have created one dropdown for employee Role. In edit mode how to select user selected role.
$builder->add('homePageId', \Propel\Bundle\PropelBundle\Form\Type\ModelType::class , array(
'class' => 'Admin\HomePageBundle\Model\HomePage',
'required' => true,
'multiple' => false,
'expanded' => false,
'query' => HomePageQuery::create()->orderByName(),
'property' => 'name',
'preferred_choices' => array('5')
));
I have added "preferred_choices" for select "5" number role but not working.
Please help for fixed this issue.
The selected value is the object value. I'll try to explain this way:
$object = new Object();
$object->setHomePageId(5);
// kinda put the 5 as selected in your form, because your object contains 5 and the form is not binded yet.
$form = $this->createForm(ObjectType, $object);
$form->getData()->getHomePageId(); // will return 5
//kinda put the request parameter homepageId as selected in your form
$form->handleRequest($request);
$form->getData()->getHomePageId(); // will return the user selection
I mean to have custom date handler in views ,according to documentation of views i should implement hook_views_api and hook_views_data .
my pseudo
function mymodule_views_api() {
return array(
'api' => views_api_version(),
);
}
and in hook_views_data()
function mymodule_views_data() {
$data = array();
$data['node']['created'] = array(
'group' => t('Mul2'),
'title' => t('Post date'), // The item it appears as on the UI,
'help' => t('The date the content was posted.'), // The help that appears on the UI,
'field' => array(
'handler' => 'views_handler_field_date',
'click sortable' => TRUE,
),
'sort' => array(
'handler' => 'views_handler_sort_date',
),
'filter' => array(
'handler' => 'views_handler_filter_date',
),
);
return $data;
}
It's ok and create a views field gorup (Mul2),
I set it hanlder date handler for test, but it not work correctly and just show Mul2: Array , and broken/missing handler in configuration of it.
I try successfully get data of custom table with views data .Is it correct to set handler for a field before handlered (like created in node ) ?
any solution?any idea?
Method of Impelementation is correct, my mistake was in use a field that before set handler for it $data['node']['created'] .
if you want to change default handler of handled field you have use hook_views_data_alter(&$data) instead of try to set handler for it again!!!(Mul2:array because of you try to set handler for handled field).
So this is my form :
$active = array(0 => t('Poster'), 1 => t('Postcard'), 2=>t('Post it'));
$form['radioimage']['active'] = array(
'#type' => 'radios',
'#default_value' => isset($node->active) ? $node->active : 1,
'#options' => $active,
);
I want to know which radio button was selected. I am trying to access the data but I don't know what its called I can't even use devel for some reason.
I tried below but they all failed
$form_state['values']['radioimage']['active'][0]
$form_state['values']['radioimage']['active']
Drupal flattens the values in the $form_state array by default so
$form['radioimage']['active']
will actually come out in
$form_state['values']['active']
If you want to explicitly keep your naming hierarchy then you should set the #tree key on the parent element:
$form['radioimage'] = array(
'#type' => 'container',
'#tree' => TRUE
);
In that case the value will be in
$form_state['values']['radioimage']['active']
I have a form which has textfields with default values specified. On submit event, I want these default values to be changed with the new set of values that I am passing. I am using form_set_value($element, $value, $form_state) for this. However it is not updating. Any ideas? My code is
function sample_myform($form_state){
$form['field']['name'] = array(
'#type' => 'textfield',
'#title'=> 'Name: ',
'#maxlength'=> 127,
'#default_value' => param1,
);
$form['field']['placeholder'] = array(
'#type'=> 'value',
'#value' => array(),
);
$form['field']['button1'] = array(
'#type' => 'submit',
'#value' => 'Submit',
);
return $form;
}
function sample_myform_validate($form,&$form_state){
$name2 = $form_state['values']['name'];
form_set_value($form['field']['placeholder'], $name2, $form_state); */
form_set_value($form['field']['name'],'God',$form_state);
$form_state['rebuild'] = true;
}
One thing for sure, $form['field']['placeholder'] will never, ever change since you set #value. Once #value is set, Form API moves on. Be careful though with setting just #default_value on a #type value as that can be tampered with. You can do something like $form_state['placeholder'] = $name2; in validate and use that in the form builder function.
What you try to do with name works in Drupal 7 but I suspect you are in Drupal 6. The validate function overwrites $form_state['values'] just fine but that's not persisted for the form rebuild. Once again, save into $form_state as you need.
