在mysql codeigniter中插入和更新一个查询

分类: 技术问答 • 2022-07-01 22:53:09
问题描述：

我是codeigniter的新手，我正在做以下的事情，但我没有得到解决方案。在mysql codeigniter中插入和更新一个查询

以下是一件一件的事情。

  1. 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。 $''''''''''''''''''''''''''''''''）; echo form_open（'emp_hodm_update/update_hodm'，$ attributes）; ？ >

    日期 工作 合作伙伴 主任 时间 任务 状态 行动 日期;？> “类= ”“/> 工作;？>” class =“”/> partner;？>“class =”“/> 主任;？> “类= ”“/> 时间;？>” 类= “”/> 任务;？> 状态;？> 删除

  2. 通过点击添加按钮它会创建新的行所以我想更新旧的数据以及通过添加buttond插入到表中创建的新行数据。

  3. 但我没有得到任何想法如何做到这一点。

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; 
    }
  1. 请帮我找到解决方案。

    2. 预先感谢

为什么单击添加按钮时需要更新旧数据？只需在控制器中创建一个添加功能，并在添加按钮被点击时调用该功能 – Sultan

您实际上没有提到问题所在！除了_但我没有得知任何想法如何做到这一点。在这种情况下，解决方案是击中书籍 – RiggsFolly

@苏丹你没有得到我。当我点击添加按钮，然后它创建同一列的新行空白。在填充新行并在旧行更改时，当我单击提交按钮时，它会进入带有旧数据和新数据的表格 – xr33dx

使用下面的代码视图中看到 增加一个列的updated_at

如果有独特之处在于表/主键，添加密钥为每个数据。假设关键是task_id，更新您的控制器代码：

... 
    ... 
    ... 
    '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);

在模型中，更新与下面的代码功能：

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); 
}
