我正在開發一個廣告網站，任何人都可以上傳 3 張圖片。因此，我正在編碼以通過在文件名前添加時間戳來上傳這 3 張圖像，使它們獨一無二。我使用 codeigniter 框架并附上下面的代碼。當我提交表單數據時，本地主機服務器顯示圖像已正確保存，并帶有一些圖像文件名的代碼信息。但問題是沒有以該名稱保存在相關圖像文件夾中的圖像，我無法在下一個預覽廣告頁面中檢索該圖像。我不太了解 php 或 codeignitor。非常感謝您的幫助。 $config['upload_path'] = './assets/images/adsimages'; $config['allowed_types'] = 'gif|jpg|png'; $config['max_size'] = 5120; $this->load->library('upload',$config); $this->upload->initialize($config); if (!$this->upload->do_upload()){ $errors = array('error' => $this->upload->display_errors()); $post_image = 'no_image.jpg'; } else { $data = array('upload_data' => $this->upload->data()); $post_image1 = time().$_FILES['userfile1']['name']; $post_image2 = time().$_FILES['userfile2']['name']; $post_image3 = time().$_FILES['userfile3']['name']; } $result = $this->post_model->adregister($post_image1,$post_image2,$post_image3);

您可以在上傳庫的配置中將時間附加到“文件名”
$config['file_name'] = time().$_FILES['userfile1']['name'];
或者，如果您想要所有文件的唯一名稱，只需添加
$config['encrypt_name'] = TRUE;
然后
$this->load->library('upload', $config);

試試這個：-
$path = pathinfo($_FILES["userfile1"]["name"]);
$image_path = $path['filename'].'_'.time().'.'.$path['extension'];

我已經為您的代碼編寫了一個可能的解決方案。您還沒有共享完整的代碼，因此您必須自己填補空白，并且可能會在這里或那里進行一些更改；必要時會提及評論?？纯此欠駥δ阌袔椭?/p>
public function your_function_name(){
// your-code
// your-code
// check if file is uploaded in field1
if(!empty($_FILES['userfile1']['name'])){
// call function to upload file
$userfile1 = $this->upload_file('userfile1');
}
// check if file is uploaded in field2
if(!empty($_FILES['userfile2']['name'])){
$userfile2 = $this->upload_file('userfile2');
}
// check if file is uploaded in field3
if(!empty($_FILES['userfile3']['name'])){
$userfile3 = $this->upload_file('userfile3');
}
$result = $this->post_model->adregister($userfile1, $userfile2, $userfile3);
}
// function to upload file
function upload_file($filename){
$config['file_name'] = time().$_FILES[$filename]['name']; // append time to filename
$config['upload_path'] = './assets/images/adsimages';
$config['allowed_types'] = 'gif|jpg|jpeg|png|GIF|JPG|PNG|JPEG';
$config['max_size'] = 5120;
$this->load->library('upload', $config);
$this->upload->initialize($config);
$uploaded = $this->upload->do_upload($filename);
if ( ! $uploaded ){
$error = array('error' => $this->upload->display_errors());
$file = 'no_image.jpg'; // default file
}else{
$upload_data = $this->upload->data();
$file = $upload_data['file_name']; // uploaded file name
}
return $file; // return filename
}
