代码点火器使用单个查询从不同模型中删除数据

Question

[我想使用两个模型从两个表中删除数据，但不能这样做。我正在使用以下代码。帮助我解决这个问题]

public function delete_all_info_employee($id) {
        // ************* Delete into Employee Table 
        $this->employee_model->_table_name = "tbl_employee"; // table name
        $this->employee_model->_primary_key = "employee_id"; // $id
        $this->employee_model->delete($id);
 $this->expense_model->_table_name = "tbl_expense"; // table name
        $this->expense_model->_primary_key = "expense_id"; // $id
        $this->expense_model->delete($id);
    $type = "success";}

Answer 1

首先检查你已经在codeigniter \ application \ config \ autoload.php中加载了数据库

$autoload['libraries'] = array('database');

您的模型方法

public function delete_all_info_employee($id) {
    // ************* Delete into Employee Table 
    $this->db->where('employee_id', $id);
    $this->db->delete('tbl_employee');

    $this->db->where('expense_id', $id);
    $this->db->delete('tbl_expense');
    return "success";
}
