如何指定上传的文件名？

Question

// This code helps me submit a picture into my images folder. However the file keeps its original name because of the function basename. How can I add a specific name to the file? Like logo.png?

<?php
      if(isset($_POST['submit'])) {
        //PROCESS FORM DATA
        $tmp_file = $_FILES['file_upload']['tmp_name'];
        $target_file = basename($_FILES['file_upload']['name']);
        $upload_dir = "images";

        //Move file
        //False als die niet correct is
        if (move_uploaded_file($tmp_file, $upload_dir."/".$target_file)) {
          $message = "File upload succesfull";
        } else {
          $error = $_FILES['file_upload']['error'];
          $message = $upload_errors[$error];
        }
      }
?>

Html form:

  <form action="upload_logo.php" enctype="multipart/form-data" method="POST">
    Select .png logo to upload:
    <input type="hidden" name="MAX_FILE_SIZE" value="1000000" />
    <input type="file" name="file_upload" />

    <input type="submit" name="submit" value="Upload" />
  </form>

Your code looks like it is pretty nearly there - just generate the name you want, grab the original file extension and append to make new name

<?php
      if(isset($_POST['submit'])) {

        $tmp_file = $_FILES['file_upload']['tmp_name'];

        $target_file = 'logo.' . pathinfo( $_FILES['file_upload']['name'], PATHINFO_EXTENSION );

        $upload_dir = "images";


        if (move_uploaded_file($tmp_file, $upload_dir."/".$target_file)) {
            $message = "File upload succesfull";
        } else {
            $error = $_FILES['file_upload']['error'];
            $message = $upload_errors[$error];
        }
      }
?>
