Php 如何在form_下拉列表中显示db结果

我想将此查询结果显示为表单下拉列表

型号

public function deptlist_view() {
    $this -> load -> database();
    $query = $this -> db -> query('select var_staffdepartment from tbl_admin');
    return $query -> result();

}

控制器

public function view_dept() {
    $this -> load -> model('model_database');
    $deptdata['query'] = $this -> model_users -> deptlist_view();

    $this -> load -> view('signup', $deptdata);

}

public function view_dept() {
  $this -> load -> model('model_database');
  $query = $this -> model_users -> deptlist_view();
  $tempArray=array();
  foreach($query as $row){
     $tempArray[$row->var_staffdepartment]=$row->var_staffdepartment;
  }
  $data['department']=$tempArray;
   $this -> load -> view('signup', $data);

}

查看

     <?php $dept= ????  ?>



        <?php echo form_open('welcome/signup_validation'); ?>

         <table align="center">


    <tr>
   <td>
    <p> Departments :</p>
    </td>
            <td><?php  echo form_dropdown('staffdept', $dept); ?></td>


                        </table>

                    <?php echo form_close(); ?>

 <?php echo form_open('welcome/signup_validation'); ?>

  <table align="center">
  <tr>
    <td>
      <p> Departments :</p>
    </td>
    <td><?php  echo form_dropdown('staffdept', $department); ?></td>
   </table>

    <?php echo form_close(); ?>

您能否演示如何解决此问题？这将是非常有益的。提前感谢。

您需要在一个数组中传递下拉选项，如

 $options = array(
               'small'  => 'Small Shirt',
              'med'    => 'Medium Shirt',
              'large'   => 'Large Shirt',
              'xlarge' => 'Extra Large Shirt',
            );

所以我创建了一个新数组。。以正确的数组格式添加选项并显示在视图中

试试这个

控制器

public function view_dept() {
    $this -> load -> model('model_database');
    $deptdata['query'] = $this -> model_users -> deptlist_view();

    $this -> load -> view('signup', $deptdata);

}

public function view_dept() {
  $this -> load -> model('model_database');
  $query = $this -> model_users -> deptlist_view();
  $tempArray=array();
  foreach($query as $row){
     $tempArray[$row->var_staffdepartment]=$row->var_staffdepartment;
  }
  $data['department']=$tempArray;
   $this -> load -> view('signup', $data);

}

查看

     <?php $dept= ????  ?>



        <?php echo form_open('welcome/signup_validation'); ?>

         <table align="center">


    <tr>
   <td>
    <p> Departments :</p>
    </td>
            <td><?php  echo form_dropdown('staffdept', $dept); ?></td>


                        </table>

                    <?php echo form_close(); ?>

 <?php echo form_open('welcome/signup_validation'); ?>

  <table align="center">
  <tr>
    <td>
      <p> Departments :</p>
    </td>
    <td><?php  echo form_dropdown('staffdept', $department); ?></td>
   </table>

    <?php echo form_close(); ?>
