cakephp helper ajax,jquery - CakePHP AJAX call - Stack Overflow

CakePHP has a JS Helper to help write aJax functions. The only catch is to include jquery in your head our cake will throw jQuery errors.

Your Form:

echo $this->Form->create('User', array('default'=>false, 'id'=>'YourForm'));

echo $this->Form->input('username');

echo $this->Form->submit('Check Username');

echo $this->Form->end();

?>

The Ajax Function:

$data = $this->Js->get('#YourForm')->serializeForm(array('isForm' => true, 'inline' => true));

$this->Js->get('#YourForm')->event(

'submit',

$this->Js->request(

array('action' => 'checkUsername', 'controller' => 'user'),

array(

'update' => '#na',

'data' => $data,

'async' => true,

'dataExpression'=>true,

'method' => 'POST'

)

)

);

echo $this->Js->writeBuffer();

?>

The Function in User Controller

function checkUsername(){

$this->autoRender = false;

//run your query here

if ( $username == true )

echo 'Username is taken';

else

echo 'Username is not taken';

}
