我有一个递归函数，带有一个我遇到问题的错误。逻辑如下：表单具有各种类型的字段。一种类型的字段是引用字段，它将表单链接到另一个表单。而且，参考文献可以链接。例如：我可以有一个处方表格，里面有一个参考文献，对医生有一个提及人的参考。同样的相遇表格有一个对病人的引用，也指人。递归函数逻辑问题

因此，医生姓氏的参考字段链看起来像处方上的字段49指的是遇到。 Encounter上的Field 7是指Doctor。 Doctor上的第6场是指Person。个人领域1指的是姓氏。 [49-7-6-1]

患者姓氏的引用链将遵循相同的逻辑[49-5-4-1]。

我的问题是这样的。使用当前函数，如果我在较低级别分支引用，则引用链字符串会有问题。 [49-5-4-1]代替患者姓氏[49-5-4-1]，我得到[49-7-5-4-1]。

功能如下：

function get_reference_fields($form_id, $base_fields = array(), $ref_field_id = null, $ref_string = null, $field_name = null,$base_form = null,$form_name=null) { 

     if(!$base_form) { 
      $base_form = $form_id; 
     } 
     App::import('model', 'Section'); 
     $zmr_sections = new Section(); 


     $sectionList = $zmr_sections->getSectionList($form_id); 


     if ($sectionList) { 

      $new_base_fields = $this->Field->find('list', array('joins' => array(
       array(
        'table' => 'field_types', 
        'alias' => 'Type', 
        'type' => 'left', 
        'foreignKey' => false, 
        'conditions' => array('Type.id = Field.field_type_id') 
       )), 'conditions' => array('Type.base_type != "formatting" AND Type.base_type != "reference" AND Type.base_type != "reverse reference"', 'Field.active=1', 'Field.section_id IN (' . $sectionList . ')'))); 


      if ($ref_field_id) { 
       $newFields = array(); 


       foreach ($new_base_fields AS $key => $field) { 
        if ($field_name) { 

         $field = $form_name . ' - ' . $field; 
        } 

        $newFields[$ref_string . '-' . $key] = $field; 

       } 
       $new_base_fields = $newFields; 
      } 
      if (!$base_fields) { 
       $base_fields = array(); 
      } 

      $base_fields = $base_fields + $new_base_fields; 


      $reference_fields = $this->Field->find('all', array('joins' => array(
       array(
        'table' => 'field_types', 
        'alias' => 'Type', 
        'type' => 'left', 
        'foreignKey' => false, 
        'conditions' => array('Type.id = Field.field_type_id') 
       )), 'conditions' => array('Type.base_type' => 'reference', 'Field.active=1', 'Field.section_id IN (' . $sectionList . ')'))); 


      foreach ($reference_fields AS $reference_field) { 

       $field_name = $reference_field['Field']['name']; 
       $query = "SELECT form_id FROM zmr_lists WHERE id=" . $reference_field['Field']['zmr_list_id']; 

       $list_data = $this->query($query); 
       $new_form_id = $list_data[0]['zmr_lists']['form_id']; 



       if($form_id == $base_form){ 
        $ref_string = $reference_field['Field']['id']; 
        $form_name = $this->Field->Section->Form->field('Form.label',array('Form.id'=>$new_form_id)); 

       }else{ 
        $ref_string .= '-'. $reference_field['Field']['id']; 
        $form_name .= '-'. $this->Field->Section->Form->field('Form.label',array('Form.id'=>$new_form_id)); 

       } 
       $base_fields = $this->get_reference_fields($new_form_id, $base_fields, $reference_field['Field']['id'], $ref_string, $field_name,$base_form,$form_name); 

      } 


     } 

     return $base_fields; 

    }

谁能帮我找出一种算法正常地生成参考链？请注意，表单在技术上可能是指自己。例如，医生可以有另一位医生的参考（见习生或主管等）

只是为了确认，你说，最初的“$ zmr_sections-> getSectionList（$ form_id）;”打电话，而不是主要表格（我想是49）没有得到第5部分，它应该，还是它回来了，但没有包含在结果中？尽管这个循环可能效率很低，但在这方面我看不出任何明显的错误。 – 2011-03-09 16:35:49

实际的问题是，当它参考了医生之后，当它循环通过时，它不会将该ID放到医生的领域，而是在患者链上附加到医生的领域。患者连锁店不应该包括7。 – 2011-03-09 16:37:46

我找到了答案。我知道ref_string的初始化是问题。我无法理解它。我加入这个递归函数调用后立即

if ($ref_string) { 
         $ref_array = explode('-', $ref_string); 
         array_pop($ref_array); 
         $ref_string = implode('-', $ref_array); 
         $form_name_array = explode('-', $form_name); 
         array_pop($form_name_array); 
         $form_name = implode('-', $form_name_array); 
        }
