我有一个从数据库填充的下拉列表。它工作正常但在视图文件中我希望下拉列表在所有值的最顶部显示“SELECT”。请你帮帮我吗?
先谢谢
我在控制器中有这个
// To get the batch name
$this->load->model('dropdown_batchlist');
$data['dropdown_batchlist']= $this->dropdown_batchlist->dropdown_batchlist();
这在我的模型中 -
function dropdown_batchlist() {
$this->db->select('batchname, batchid');
$records=$this->db->get('batch');
$data=array();
foreach ($records->result() as $row)
{
$data[$row->batchid] = $row->batchname;
}
return ($data);
}
这在我的视图文件中
<?php echo form_dropdown('batchid', $dropdown_batchlist ); ?>
答案 0 :(得分:3)
您只需添加'SELECT'作为数组中的第一项:
function dropdown_batchlist() {
$this->db->select('batchname, batchid');
$records=$this->db->get('batch');
$data=array();
// add it here as the first item in the array,
// assuming you don't have a $row->batchid of 0 in your results.
$data[0] = 'SELECT';
foreach ($records->result() as $row)
{
$data[$row->batchid] = $row->batchname;
}
return ($data);
}
