Using:
CakePHP 1.1.19.6305
jquery-1.2.6.min.js
In the view:
<tr><td align="right" class="label_14" width="200px">select a
campaign: </td><td align="left"><?php echo $html-
>selectTag( 'Campaign/CampaignID', $options_C, null, array( 'onchange'
=> 'display_select_event()','id' => 'select_campaign' ), null, true,
false ); ?></td></tr>
In the JavaScript:
function display_select_event()
{
.
.
.
// get the events for this campaign.
$.get( 'Attendance/get_events', { campaign_id: selected_index },
function( xml ) { alert( xml ); }, 'XML' );
.
.
.
}
In the controller:
function get_events( $campaign_id )
{
$conditions = array( 'CampaignID' => $campaign_id );
$fields = array( 'CEventID', 'Name' );
$result = $this->Event->findAll( $conditions, $fields, null, null,
1, null );
if( count( $result ) )
{
$xml = '<?xml version=\"1.0\" standalone=\"yes\"?>';
foreach( $result as $key => $value )
{
foreach( $value as $id => $name )
$xml .= '<event>';
$xml .= '<id>' . $value['Event']['CEventID'] . '</id>';
$xml .= '<name>' . $value['Event']['Name'] . '</name>';
$xml .= '</event>';
}
}
else
{
// What if there are no events for this campaign.
}
}
The function, get_events(), produces the correct, well-formed XML
document. But Cake is complaining about the missing view for
"get_event" and the jQuery is not returning the XML document produced
by get_events().
A link to an example of what I am trying to do would be sufficient and
greatly appreciated but if you spot the errors in my code that would
be appreciated also.
