Codeigniter：this->datatables->select(sample)->from(sample)->where()

Question

请帮助我。我无法正确使用我的数据表。我想做的是

select from table and use thewherefunction。但我做不到。

这是我的控制器代码

 public function reporttable ()
    {

        $zz = array('empnumber' => $this->input->post('empnumber'));
        //$this->db->order_by("surname", "asc");
         $this->datatables->select('date_auto,particulars,earned_VL,aul_VL,balance_VL,aulx_VL,earned_SL,aul_SL,balance_SL,aulx_SL,date_leave,action_taken')
        ->from('tblreport')->where($zz);

        echo $this->datatables->generate();
    }

这是我假设的查询：

select * from tblreport where empnumber = (我的文本框中的 empnumber。)

那里，我从一个文本框中得到一个值到我的视图。但它没有用。我知道那是错误的。你能帮我解决我的问题吗？谢谢。

<p align="center"> <?php echo $this->table->generate();?></p></div>
<?php foreach ($tblemployee as $row){?> 
<input type="text" name="empnumber" readonly="readonly"  value="<?php echo $row->empnumber;?>"/>
<input type="hidden" name="empnumber" value="<?php echo $row->empnumber;?>"/>

这是我的指导意见。谢谢。

Answer 1

在控制器

$data['tblemployee'] = $this->model_name->reporttable($id)//assign your data base value to variable $this->load->view('your view name',$data )

在模型

public function reporttable($id) { $query = $this->db->query("select * from tblreport where empnumber = '$id'"); $result = $query->result_array(); return $result; // this will return your data as array }

在查看

<?php foreach ($tblemployee as $row) { echo $row['id]; }?>

试试这个：

为了让它更简单。

在模型中：

public function reporttable ($id){

  $this->db->select('*');
  $this->db->from('tblreport');
  $this->db->where('empnumber', $id);

  $query =  $this->db->get();
  return $query->return_array(); // use this if so want to return many query if not you can also use first_row('array')
}

在控制器中：

public function function_name (){
  $data['variable_name'] =  $this->model_name->reporttable($id); // change the model_name by your own model where your function reporttable is located and use the variable_name for your view,

  $this->load->view('view_name' , $data); // load the view page you want to display.
}

Answer 3

你可以使用简单

在控制器

$data['tblemployee'] = $this->model_name->reporttable($id)//assign your data base value to variable 
$this->load->view('your view name',$data )

在模型

public function reporttable($id)
    {
    $query = $this->db->query("select * from tblreport where empnumber = '$id'");
    $result = $query->result_array();
    return $result; // this will return your data as array
}

在查看

<?php 
foreach ($tblemployee as $row)
{
echo $row['id];
