Question

我是codeigniter的新手，我正在做以下事情，但我没有得到解决方案。

以下是一个接一个的事情。

首先，我从数据库中获取数据，并通过foreach循环以表格格式显示。
```
<?php
```
$ attributes = array（'class'=＆gt;'form-horizontal'，'id'=＆gt;'update_form'）; echo form_open（'emp_hodm_update / update_hodm'，$ attributes）; ？＆GT;
日期工作伙伴导向器时间任务状态行动 date;？＆gt;“class =”“/＆gt; 工作;？＆gt;“class =”“/＆gt; 合作伙伴;？＆gt;“class =”“/＆gt; 导演;？＆gt;“class =”“/＆gt; 时间;？＆gt;“class =”“/＆gt; 任务;？＆GT; 状态;？＆GT; 删除
通过单击“添加”按钮，它会创建新行，因此我想更新旧数据以及通过添加按钮创建的新行数据以插入表格。
但我不知道该怎么做。

控制器：

public function update_hodm(){

/* Checking the all validation of task form*/
//$this->form_validation->set_rules('date', 'Date', 'required');
$this->form_validation->set_rules('work[]', 'Types of Work', 'required');
//$this->form_validation->set_rules('partner[]', 'Worked With', 'required');
$this->form_validation->set_rules('director[]', 'Director', 'required');
$this->form_validation->set_rules('time[]', 'No Of Hours', 'required');
$this->form_validation->set_rules('task[]', 'Task Details', 'required');
$this->form_validation->set_rules('status[]', 'Task Status', 'required');

if ($this->form_validation->run()) {
    /* Taking the data from form*/
    $todayDate = date('Y-m-d');
    $work=$this->input->post('work');
    $partner=$this->input->post('partner');
    $director=$this->input->post('director');
    $time=$this->input->post('time');
    $task=$this->input->post('task');
    $status=$this->input->post('status');

    $count=count($this->input->post('work'));
    $data =array();
    for($i=0; $i<$count; $i++) {
    $data[$i] = array(
        'name'       =>$this->session->userdata('emp_name'),
        'date'       =>$todayDate,
        'work'       =>$work[$i],
        'partner'    =>$partner[$i],
        'director'   =>$director[$i],
        'time'       =>$time[$i],
        'task'       =>$task[$i],
        'status'     =>$status[$i]
        );
        }
        $add=$this->update->update_hodm($data,$todayDate);
        /* Display Success message if data updated successfully in database*/

            if($add){
                $this->session->set_flashdata('hodm_form',"All HODM Data Inserted Successfully.");
                $this->session->set_flashdata('hodm_form_class','alert-success');
            }else{
                /* Displaying the error message*/
                $this->session->set_flashdata('hodm_form',"failed to add, Please Try again");
                $this->session->set_flashdata('hodm_form_class','alert-danger');
            }
        return redirect('home');
} else {
    $this->load->view('public/digital_hodm_view');
}
}

型号：

public function update_hodm($data,$todayDate){
        $this->db->where('date',$todaydate);
        $this->db->update_batch('task_form', $data,'date');//date is my table column name 
        return true;
    }

请帮我找到解决方案。

提前致谢

Answer 1

如果该表中有唯一/主键，请为每个数据添加密钥。假设密钥为task_id，请更新控制器中的代码：

    ...
    ...
    ...
    'task'       =>$task[$i],
    'status'     =>$status[$i]
    );  
    if(!empty($task_id[$i]))$data[$i]['task_id'] = $task_id[$i]; //Add task ids for old data
   }
   $add=$this->update->update_hodm($data,$todayDate);

在您的模型中，使用以下代码更新函数：

foreach($data as $array)
{
  $query = 'INSERT INTO `table` SET ';
  $sep = $setvalues = '';
  foreach($array as $key=>$value) {
    $setvalues .=  $sep.$key.' = "'.$value.'"';
    $sep = ',';
  }
  $query .= $setvalues.' ON DUPLICATE KEY UPDATE '.$setvalues.';';      
  $this->db->query($query);
}

使用以下代码查看再添加一列updated_at
