我想使用cakephp search plugin，我在使用查询方法过滤结果时遇到问题。我创建了一个名为findByLength（）的函数，它在$ filterArgs数组中声明。我不确定我正在建设的阵列是否正确。当我查看sql语句时，它看起来好像没有被调用。有任何想法吗？谢谢！Cakephp（CakeDC）搜索插件自定义过滤方法
<?php
// findByLength() is not affecting the sql like expected. Any ideas?
// using http://cakedc.com/downloads/view/cakephp_search_plugin
public $filterArgs = array(
array('name' => 'name', 'type' => 'like'),
array('name' => 'search', 'type' => 'like', 'field' => 'Trail.description'),
array('name' => 'type','type'=>'string'),
array('name'=>'dogs_allowed','type'=>'value'),
array('name'=>'area_id','type'=>'value'),
array('name' => 'length', 'type' => 'query', 'method' => 'findByLength', 'field' => 'Trail.length'),
array('name' => 'state_id','field'=>'Area.state_id', 'type' => 'value'),
array('name'=>'created_by_pt','field'=>'Trail.created_by','type'=> 'value'),
//array('name'=>'created_by_user','field'=>'Trail.created_by','type'=> 'value'),
);
public function findByLength(){
if(empty($data['Trail']['length'])){
return array();
}
switch($data['Trail']['length']){
case 0:
return array('AND'=> array($this->alias.'.length >='=> $data['Trail']['length'],
$this->alias.'.length <'=> $data['Trail']['length'] + 3)
);
break;
case 3:
return array('AND'=> array($this->alias.'.length >='=> $data['Trail']['length'],
$this->alias.'.length >'=> $data['Trail']['length'] + 3)
);
break;
case 6:
return array('AND'=> array($this->alias.'.length >='=> $data['Trail']['length'],
$this->alias.'.length <'=> $data['Trail']['length'] + 4)
);
break;
case 10:
return array('AND'=> array($this->alias.'.length >='=> $data['Trail']['length'])
