回拨前杂货CRUD嵌件不起作用

Question

我的控制器，镶在表中invHdrData表， 行我想最大文件号码中插入文档自动编号 回调插入之前没有作品。 那么问题在哪里？ 我将不胜感激，如果你请给我一些答案:)

我的控制器：

 public function sanads() 
{ 
     $crud = new grocery_CRUD(); 
     $crud->set_theme('datatables'); 
     $crud->set_table('invhdrdata'); 
     $crud->set_subject('BLAH BLAH BLAH'); 
     $crud->columns('FiscalYear','StoreNo','DocType','CreateDate','UpdateDate'); 
     $crud->fields('FiscalYear','StoreNo','DocType','DocNo','CreateDate','UpdateDate'); 
     $crud->callback_before_insert(array($this,'maxDocNoCon')); 
     $crud->field_type('DocNo','invisible'); 
     $output = $crud->render(); 
     $this->_example_output($output); 
} 

另一种功能的控制器：

public function maxDocNoCon($post_array) { 
    $this->load->model('inv_model'); 
    $post_array['DocNo'] = $this->inv_model->maxDocNoMod($post_array['FiscalYear'],$post_array['StoreNo'],$post_array['DocType']); 
    $test['DocNo'] = (int)explode(",", $post_array['DocNo'])+1; 
    return $test; 
} 

我的模型：

function maxDocNoMod($FiscalYear,$StoreNo,$DocType){ 
    $this->db->select_max('DocNo'); 
    $this->db->where('FiscalYear', $FiscalYear); 
    $this->db->where('StoreNo', $StoreNo); 
    $this->db->where('DocType', $DocType); 
    $data = $this->db->get('invhdrdata'); 
    if ($data->num_rows() != 1) { 
     // there should only be one row - anything else is an error 
     return false; 
    } 
    return $data->row()->DocNo; 
}

问题解决。 我将控制器改为：

public function maxDocNoCon($post_array) { 
    $this->load->model('inv_model'); 
    $post_array['DocNo'] = $this->inv_model->maxDocNoMod($post_array['FiscalYear'],$post_array['StoreNo'],$post_array['DocType'])+1; 
    if ($post_array['DocNo'] == 1){ 
     $post_array['DocNo'] = 10001; 
    } 
    return $post_array; 
}
