奧基，所以我有搜索和嘗試一切從谷歌，但我很堅持。 我想在我現有的CodeIgniter項目上使用上傳功能。 我要上傳他們，然後向他們展示我與64×64像素大小視圖，而真正的大小是320×320像素。笨如何上傳圖片連接表
我加入了兩個表，從另一個表中獲取'name'字段，所以當我需要添加新數據時，我可以在我的添加數據視圖中顯示它們，並且我設法做到這一點，但我很困惑如何把上傳代碼/函數導致我有'add_data'函數，我用它來保存'tambah_mahasiswa'視圖發佈到數據庫中的內容。 我試圖在'add_data'函數上結合'do_upload'函數，但它仍然不起作用。 我該如何解決這個問題？
這是tb_mahasiswa表我的照片領域：

這是我的控制器代碼= 'ControlPanel控制'：

} else {

}
}
function do_upload()
{
$config['upload_path'] = $this->path_uploads;
$config['allowed_types'] = 'gif|jpg|png';
$config['max_size'] = '100';

else
