是否有可能使用三元运算符或某种东西来检查字段是否为空，如果是的话，更新部分应该忽略空白字段。编辑

在写上下文中实际无法获得该返回的唯一方法是：

if($this->input->post('email') != "")
{
    $update_data['email'] = $this->input->post('email');
}

if($this->input->post('phone_number') != "")
{
    $update_data['phone_number'] = $this->input->post('phone_number');
}
if($this->input->post('new_password') != "")
{
    $update_data['password'] = $this->input->post('new_password');
}

但它仍然会更新所有字段，包括那些空字段。

答案是否。您不能在本例中使用三元运算符。如果使用三元运算符，请签出以下代码：

$edit_data['email'] = ($this->input->post('email') && !empty($this->input->post('email'))) ? $this->input->post('email') : NULL;

$edit_data['phone_number'] = ($this->input->post('phone_number') && !empty($this->input->post('phone_number'))) ? $this->input->post('phone_number') : NULL;

$edit_data['new_password'] = ($this->input->post('new_password') && !empty($this->input->post('new_password'))) ? $this->input->post('new_password') : NULL;

如果我们使用三元运算符，我们将强制创建

$edit_data['password']

数据，即使密码为空，我们也不希望这样做。如果用户输入密码，那么它将把密码存储在

$edit_data['password']

中，但是如果用户将密码保留为空，

null

将被存储在

$edit_data['password']

中，这反过来会留下一个空白字段更新

        $this->form_validation->set_message('matches', 'Uudet salasanat eivät täsmää');
        $this->form_validation->set_message('required', '%s - kenttä on pakollinen');
        $this->form_validation->set_message('is_unique', '%s on jo rekisteröity');

        if($this->form_validation->run() == FALSE)
        {
            $this->output->set_content_type('application_json');
            $this->output->set_output(json_encode(array('result'=>0, 'error' => $this->form_validation->error_array())));
            return false;

        }

        $edit_data = array();

           if($this->input->post('email')) 
                $edit_data['email'] = $this->input->post('email');

            if($this->input->post('phone_number'))
                $edit_data['phone_number'] = $this->input->post('phone_number');

            if($this->input->post('new_password'))
                $edit_data['new_password'] = $this->phpass->hash($this->input->post('new_password'));

        $edit_info = $this->user_model->edit_user($edit_data, $this->session->userdata('user_id'));


        if($edit_info)
        {

            $this->output->set_content_type('application_json');
            $this->output->set_output(json_encode(array('result'=>1, 'success' => 'Uusi käyttäjä lisätty')));

        } else {

            $this->output->set_content_type('application_json');
            $this->output->set_output(json_encode(array('result'=>0, 'error' => 'Tietojen päivittäminen epäonnistui')));
        }

 }

使用

isset（）

和

empty（）

函数作为

if语句中的条件
if(!empty($this->input->post('new_password')))
{
    $edit_data['new_password'] = $this->input->post('new_password');
}


更新
从控制器发送更新时使用的数组，并在查询中直接使用它。如果用户输入的是电子邮件
和电话号码
，而不是新密码

在控制器中
if($this->input->post('email') != "")
{
   $update_data['email'] = $this->input->post('email');
}

if($this->input->post('phone_number') != "")
{
   $update_data['phone_number'] = $this->input->post('phone_number');
}

if($this->input->post('new_password') != "")
{
   $update_data['password'] = $this->input->post('new_password');
}

$edit_info = $this->user_model->edit_user($edit_data, $this->session->userdata('user_id'));

// Since email, phone_number, password are the column names of the table
// you can directly use $update_data array in your query
// which prevent from inserting blank values in unfilled fields 

您的阵列
Array(
[email] => abc@gmail.com
[phone_number] => 9999999999
)

在型号中
public function edit_user($data, $user_id) 
{
    $this->db->where('id', $user_id);
    $this->db->update('users', $data);
}

在我做了上面u所说的之后，我得到了这个错误：致命错误：无法在第370行的application/controllers/users.php的write上下文中使用方法返回值。问题是，由于未知的原因，无法将isset（）和empty（）函数与$this->input->post（）一起使用me@B_CooperA检查更新。
