Hi all,
my problem is occurring with creating a dropdown box that when
selected, AJAX will place another dropdown box below it filled with
choices according to the value chosen in box 1.
I use the following code to generate the first dropdown box:
<?php
echo select_tag('department_choice', objects_for_select($depts,
'getName', 'getName'),
array( 'onchange' => remote_function( array(
'update' => 'classSelection',
'url' => 'departments/GetCourses',
'with' => "'id=' + this.options[this.selectedindex].value",
'loading' => "Element.show('indicator')",
'complete' => "Element.hide('indicator')"
) )
));
?>
<div id="classSelection">
</div>
executeGetCourses in action.class.php, which will take the value from
Box 1 and retrieve only the values from the CRN column of my 3 column
table that have the same Name column value as the id chosen:
public function executeGetCourses()
{
$CRNcrit = new Criteria();
$CRNcrit -> clearSelectColumns();
$CRNcrit -> addSelectColumn( OfferedPeer::CRN );
$CRNcrit->add( OfferedPeer::Name, $this-
>getRequestParameter('id') );
$this->crns = OfferedPeer::doSelect( $deptCrns );
}
and this is getCoursesSuccess.php:
<?php
use_helper('Object');
echo select_tag( 'classes', objects_for_select($crns, 'getCRN',
'getCRN') );
?>
Is there anything wrong with this code, because when i execute it in
my web page, nothing happens when i choose an option in box 1?
