php - 插入前回调在 Grocery CRUD 中不起作用

Question

我的 Controller ，在 invHdrData 表中插入一行，我希望该表中的最大文档编号自动插入文档编号插入之前的回调不起作用。那么问题出在哪里呢？如果您能给我一些答案，我将不胜感激:)

我的 Controller :

        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);
}

Controller 中的另一个函数:

    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;
}

问题已解决。我将 Controller 更改为以下内容:

    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;
}
