就像是
public function delete_video($id)
{
$this->db->where('id', $id);
$this->db->select('video');
$video_name = $this->db->get('vs_videos')->row_array();
if ($video_name) {
@unlink('./vs_asset/videos/' . $video_name['video']);
$this->db->where('id', $id)
->delete('vs_videos');
$result = $this->db->affected_rows();
return $result;
} else {
return;
}
}

$filename = file_name_with_full_path
您可以使用 unlink($filename) 函數(shù)在 php 中刪除文件

非常感謝，我得到了答案
這里是如何工作的。
public function delete($id = null) {
if (!$id)
show_404();
$this->{$this->model}->{$this->_primary_key} = $id;
$path = './cdn/projects/';
$data['item'] = $this->{$this->model}->get();
if (!$data['item'])
show_404();
@unlink($path.$data['item']->image);
$this->{$this->model}->delete();
redirect('admin/' . $this->module);
}
