Hi All,

In this blog we will discuss about how to set checkbox checked in cakePhp application.

You should set the checkbox checked/selected with the 'selected' option.

For example-

You can find a list of categories from the database table called Category as shown below:

$catLists= $this->Category->find('list', array(
  'fields' => array('id')
));

$selectedCats= array(1,2,3);//this represents what all categories you want to be checked

Now you have to set all these values to the checkbox in cakephp's conventions

echo $this->Form->input('User.category', array(
    'label' => 'Categories',
    'type' => 'select',
    'multiple' => 'checkbox',
    'options' => $catlists,//you can set the variable as shown in above example in  here
    'selected' => $selectedCats//you can write in the list of the id's as defined in above example ,which  will automatically display checkbox as selected with id's 1,2,3.
  ));
