当我更新一列时,将更改所有列。 我该如何解决?
模型
public function update($where, $data)
{
$this->db->update($this->table, $data, $where);
return $this->db->affected_rows();
}
控制器:
public function ajax_update()
{
$data = array(
'book_title' => $this->input->post('book_title'),
'book_isbn' => $this->input->post('book_isbn'),
'book_yop' => $this->input->post('book_yop'),
'book_active' => $this->input->post('book_active'),
'publisher_name' => $this->input->post('publisher_name'),
'author_name' => $this->input->post('author_name'),
);
$this->user_model->update( $this->input->post('book_id'), $data);
echo json_encode(array("status" => TRUE));
}

基于CodeIgniter documentation,我建议更改定义“ where”部分的代码:
$this->user_model->update( array('book_id' => $this->input->post('book_id')), $data);

确保所有数据都可以正常使用,尤其是您的ID,然后像这样更新:
$this->db->where('book_id', $this->input->post('book_id'));
$this->db->update($this->table, $data);
