Question

我正在尝试更新数据库并立即更改所有行，这是我正在使用的模型：

function amend_job($title,$description,$location,$date,$time,$pay,$jobcat,$job_id) //This function amends a job.//
{ 
    $amendJob=array(
    "JobTitle"=>$title,
    "JobDescription"=>$description,
    "JobLocation"=>$location,
    "JobDate"=>$date,
    "JobStartTime" =>$time, 
    "JobPay"=>$pay, 
    "JobCategory"=>$jobcat
    ); 

    $this->db->where('JobID', $job_id);
    return $this->db->update('HM_Jobs', $amendJob);
}

代码运行时没有数据库或语法错误，我认为更新语法可能有误，有什么建议吗？

我已经更新了上面的功能，这里是控制器功能：

function amend_job()
    { 
        $this->load->library('form_validation');
        $this->form_validation->set_rules('title','Title','required|trim|max_length[50]|xss_clean|strip_tags'); 
        $this->form_validation->set_rules('description','Description','required|trim|max_length[200]|xss_clean|strip_tags');
        $this->form_validation->set_rules('location','Location','required|trim|max_length[50]|xss_clean|strip_tags');
        $this->form_validation->set_rules('date','Start Date','required|trim|max_length[20]|xss_clean');
        $this->form_validation->set_rules('time','Time','required|trim|max_length[20]|xss_clean');
        $this->form_validation->set_rules('pay','Pay Rate','required|trim|max_length[10]|xss_clean|number');        
        $this->form_validation->set_rules('jobcat','Job Category','required|trim|max_length[30]|xss_clean');

            if ($this->form_validation->run() == FALSE)
            {
                $session_data = $this->session->userdata('logged_in');
                $data['username'] = $session_data['username'];
                $data['usertype'] = $session_data['usertype'];
                $data['id'] = $session_data['id'];
                $this->load->view('amend_job_view', $data);
                return false;
            }

            else{
                //Sending form input.//
                $title=$this->input->post('title'); 
                $description=$this->input->post('description'); 
                $location=$this->input->post('location'); 
                $date=$this->input->post('date');
                $time=$this->input->post('time'); 
                $pay=$this->input->post('pay');             
                $jobcat=$this->input->post('jobcat');

                //Sending session data.//
                $session_data = $this->session->userdata('logged_in');
                $data['username'] = $session_data['username'];
                $data['usertype'] = $session_data['usertype'];
                $data['id'] = $session_data['id'];
                $job_id=$this->uri->segment(3);

                $this->load->model("job_model"); 

                    if($this->job_model->amend_job($title,$description,$location,$date,$time,$pay,$jobcat,$job_id))
                        { 
                                echo $this->db->last_query();
                            /*Start of the PHP generated JavaScript that shows the details the user registered with.
                            echo "<script language=\"javascript\" type=\"text/javascript\">\n";
                            echo "alert('That job has been successfully amended, returning to your home.');\n";
                            echo " window.location.href='(my link)'; </script>";
                            End of the PHP generated JavaScript that shows the details the user registered with.*/
                        }
                    else
                        { 
                            $data['msg']="An error was encountered when trying to add this job."; 
                        }
                }
        $this->load->view("customer_view",$data); 
    }

现在找不到$ job_id，查询是：

UPDATE `HM_Jobs` SET `JobTitle` = 'dfsdsf', `JobDescription` = 'fd', `JobLocation` = 'fds', `JobDate` = '2014-01-01', `JobStartTime` = '02:00:00', `JobPay` = '32.00', `JobCategory` = 'Carpentry/Woodwork' WHERE `JobID` = 0

我正在使用uri段，链接如下：（我的网站）/HandyMan/index.php/job_controller/amend_page/43

Answer 1

你在函数$job_id和$id中得到两个id。并且您没有在任何地方使用$id。我想你应该再次检查参数并再次检查调用功能。可能是你正在混合这两个$ ID。

Answer 2

数组中有一个额外的逗号

$amendJob=array(
    "JobTitle"=>$title,
    "JobDescription"=>$description,
    "JobLocation"=>$location,
    "JobDate"=>$date,
    "JobStartTime" =>$time, 
    "JobPay"=>$pay, 
    "JobCategory"=>$jobcat, 
                          ^
    );

删除它并将数组更改为

$amendJob=array(
    "JobTitle"=>$title,
    "JobDescription"=>$description,
    "JobLocation"=>$location,
    "JobDate"=>$date,
    "JobStartTime" =>$time, 
    "JobPay"=>$pay, 
    "JobCategory"=>$jobcat
    );

并确保数组$amendJob中的键是表的字段名。

CodeIgniter更新功能不起作用？
