Question

我试图通过添加上传者名称（$ user）来重命名上传的文件但它只是在扩展部分显示用户名，file.jpguser，这里是代码，

if ((!empty($_FILES["uploaded_file"])) && ($_FILES['uploaded_file']['error']         == 0)) {
  //Check if the file is JPEG image and it's size is less than 1.4MB
  $filename = basename($_FILES['uploaded_file']['name']);
  $ext = substr($filename, strrpos($filename, '.') + 1);

 if (($ext == "jpg") && ($_FILES["uploaded_file"]["type"] == "image/jpeg") &&
($_FILES["uploaded_file"]["size"] < 10485760))
{

//Determine the path to which we want to save this file
  $newname = dirname(__FILE__).'/affichagesimg/'.$filename'by'.$user;
  //Check if the file with the same name is already exists on the server


  if (!file_exists($newname)) {
    //Attempt to move the uploaded file to it's new place
    if ((move_uploaded_file($_FILES['uploaded_file']['tmp_name'],$newname)))         {

echo "<script>
alert('votre affichage a était publié avec succés !');
window.location.href='.';

</script>";

Answer 1

您需要拆分原始文件名（或use built in functionality）以获取扩展名。例如：

<?php
...
$file_parts = explode('.', $uploaded_filename);
$extension = array_pop($file_parts);
$file_stub = implode('.', $file_parts);
$new_name = $file_stub . 'by' . $user . '.' . $extension;

使用您的代码，新文件名为：

<?php
...
$new_filename = $filename . 'by' . $user . '.' . $ext;

Answer 2

使用pathinfo功能

$user = 'username';
$filename = $_FILES['uploaded_file']['name'];
$path_parts = pathinfo($filename);
$newname = "{$path_parts['filename']}_by_{$user}.{$path_parts['extension']}";

Answer 3

您也可以使用pathinfo来解析文件名：

$ file_parts = pathinfo（$ uploaded_filename）;

$ new_name = $ file_parts ['filename']。'by'。$ user。'。'。$ file_parts ['extension'];
