我正在開(kāi)發(fā)一個(gè)廣告網(wǎng)站，任何人都可以上傳 3 張圖片。因此，我正在編碼以通過(guò)在文件名前添加時(shí)間戳來(lái)上傳這 3 張圖像，使它們獨(dú)一無(wú)二。我使用 codeigniter 框架并附上下面的代碼。當(dāng)我提交表單數(shù)據(jù)時(shí)，本地主機(jī)服務(wù)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(wèn)題是沒(méi)有以該名稱(chēng)保存在相關(guān)圖像文件夾中的圖像，我無(wú)法在下一個(gè)預(yù)覽廣告頁(yè)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(kù)的配置中將時(shí)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(chēng)，只需添加
$config['encrypt_name'] = TRUE;
然后
$this->load->library('upload', $config);

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

我已經(jīng)為您的代碼編寫(xiě)了一個(gè)可能的解決方案。您還沒(méi)有共享完整的代碼，因此您必須自己填補(bǔ)空白，并且可能會(huì)在這里或那里進(jìn)行一些更改；必要時(shí)會(huì)提及評(píng)論。看看它是否對(duì)你有幫助。
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');
