Sorry, the code I wrote should be like this, but it still doesn't work
test_ajax.ctp
<?
echo $form->create('');
echo
$form->select('document_type_id',array($docTypes),null,array('id'=>'document'),true);
echo $form->input('document_number', array('id'=>'docnum'));
$ajax->observeField('document',array('url'=>'populate_document_select','update'=>'docnum'));
echo
$ajax->observeField('document',array('url'=>'populate_document_select','update'=>'docnum'));
echo $form->end('Save');
?>
DocumentsController
function populate_document_select() {
if(!empty($this->data['Document']['document_type_id'])) {
$options =
$this->getList($this->data['Document']['document_type_id']);
$this->set('options', $options);
}
}
function getlist($document_type_id=null) {
$doc =
$this->Document->find('first',array('conditions'=>array('Document.document_type_id'=>$document_type_id,'status'=>'new'),
'fields'=>(array('Document.document_number'))));
return $doc['Document']['document_number'];
}
populate_document_select.ctp
<?php
if (!empty($options)) {
echo $form->input('document_number', array('id'=>'docnum',
'value'=>$options));
}
?>
