$year = date("Y");

$years[$i]=$year;
}
$this->set(compact('years'));
}
View
<h1>Weekly Report</h1>
<table>
<tr>
<th>Year</th>
<th>Stores</th>
<th>Department</th>
</tr>
<?php echo $this->Form->create('StockReport',array('url'=>array('type' => 'get','action'=>'search')));?>
<tr>
<td>
<?php echo $this->Form->input('year',array('type'=>'select','options'=>$years)); ?>
</td>
<td>
<?php echo $this->Form->input('Store.name',array('type'=>'select','options'=>$stores)); ?>
</td>
<td>
<?php echo $this->Form->input('StockReportCondition.bu_no',array('type'=>'select','options'=>$departments)); ?>
</td>
</tr>
<?php echo $this->Form->end(__('Search'));?>
</table>
Controller
<?php
class StockReportsController extends AppController{
public function search(){
$year = $this->request->data['StockReport']['year'];
echo $year;
$store_no = $this->request->data['Store']['name'];

$dept_no = $this->request->data['StockReportCondition']['bu_no'];
echo $dept_no;
$result = $this->StockReport->find('all',array(
'conditions'=>array('yearweek'=>'', 'bu_no'=>'','tn_no'=>'')
));
}
}

It would seem that there's probably never a useful thing that you could do with the zero-based index of the year, and you'd only ever want the actual year value. If that's the case, then set up your options array so that the index and value are the same:
$years[$year]=$year;
