In the edit method, you also need to get the id from the hidden field and save it to data[] $data['id']=I('id');
For example, if you use the ID field as a condition to update a data row, you must pass in the ID field as a condition. And you need to add a hidden field, assign the ID to it and submit it as a form. The ID of the previous page can no longer be used
To modify, please add a hidden field to the ID value of the incoming article on the submission page
