更改圖像名稱並將其與數據庫存儲在一起php codeigniter

Question

我使用PHP Codeigniter處理項目。我想上傳圖片，更改圖片的名稱並將其存儲在數據庫中（帶擴展名）。我寫了下面的代碼。它完美的工作，但問題是，圖像名稱存儲沒有在數據庫中的擴展名。例如，當我運行代碼時，存儲在數據庫中的名稱是'imagename'，而不是'imagename.jpg'或'imagename.png'。我想存儲帶有擴展名的完整名稱。

這是我的控制器

public function FunctionName() 
{ 
    $fname = ucwords($this->input->post('fname')); 
    $lname = ucwords($this->input->post('lname')); 
    $prof_pic = $_FILES['profile_pic']['name']; 

    $config = array ('upload_path' => './images/students/', 
     'allowed_types' => "jpeg|jpg|png", 
     'overwrite' => TRUE, 
     'file_name' => $fname."_".$lname, 
     'remove_spaces' => TRUE, 
     'file_ext_tolower' => TRUE 
    ); 

    $this->load->library('upload', $config); 
    $this->upload->do_upload('profile_pic'); 

    $image_name = $config['file_name'].".".$config['file_type']; 

    $data = array('std_fname' => $std_fname, 
     'std_lname' => $std_lname, 
     'profile_pic' => $image 
    ); 
    $this->General_Model->create_record($data, "table_name"); 
} 

Answer 1

如要上傳的文件名使用

$this->upload->data('file_name'); 

AS

$this->upload->do_upload('profile_pic'); 
$image_name = $this->upload->data('file_name'); 

讀Information about the uploaded file

Answer 2

嘗試用下面的代碼

$prof_pic = $_FILES['profile_pic']['name']; 
$newName = "<Desired name>".".".pathinfo($prof_pic, PATHINFO_EXTENSION); 
$config = array ('upload_path' => './images/students/', 
    'allowed_types' => "jpeg|jpg|png", 
    'overwrite' => TRUE, 
    'file_name' => $newName, 
    'remove_spaces' => TRUE, 
    'file_ext_tolower' => TRUE 
); 

行

$newName = "<Desired name>".".".pathinfo($prof_pic, PATHINFO_EXTENSION); 

會與實際文件的文件擴展名指定新的名字
