上传时更改图片名称

-1

我想在上传图片时更改图片名称。上传时更改图片名称

这里是我的代码：

if(isset($_POST['submit'])) 
{ 
    $target_dir = "pictures/"; 
    $target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]); 
    $uploadOk = 1; 
    $imageFileType = pathinfo($target_file,PATHINFO_EXTENSION); 

    // Allow certain file formats 
    if($imageFileType != "gif") { 
     echo "Sorry only GIF files are allowed."; 
     $uploadOk = 0; 
    } 
    // Check if $uploadOk is set to 0 by an error 
    if ($uploadOk == 0) { 
     echo "Sorry, your file was not uploaded."; 
    // if everything is ok, try to upload file 
    } else { 
     if (move_uploaded_file($_FILES["fileToUpload"]["tmp_name"], $target_file)) { 
      echo "The file ". basename($_FILES["fileToUpload"]["name"]). " has been uploaded."; 
      header('Location:field_medal_winner.php'); 
     } else { 
      echo "Sorry, there was an error uploading your file."; 
     } 
    } 
}

首先我试图做到这一点蒙山改变move_uploaded_file功能。但我刚刚得到了其他信息：

if (move_uploaded_file("text.gif", $target_file)) { 
    echo "The file ". basename($_FILES["fileToUpload"]["name"]). " has been uploaded."; 
} else { 
    echo "Sorry, there was an error uploading your file."; 
}

有没有人有一个想法是什么，我做错了什么？

替换这些2线

$target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]); 
$imageFileType = pathinfo($target_file,PATHINFO_EXTENSION);

随着

$target_file = $target_dir . "text.gif"; 
$imageFileType = pathinfo($_FILES["fileToUpload"]["name"],PATHINFO_EXTENSION);

它将为保存text.gif在您需要的文件夹。但是，请记住，无论您要上传哪个文件，它都会覆盖旧的text.gif文件到text.gif，因为上传了具有相同名称的文件。

更新的代码

if(isset($_POST['submit'])) 
{ 
    $target_dir = "pictures/"; 
    $target_file = $target_dir . "text.gif"; 
    $uploadOk = 1; 
    $imageFileType = pathinfo($_FILES["fileToUpload"]["name"],PATHINFO_EXTENSION); 

    // Allow certain file formats 
    if(($imageFileType != "gif") || ($imageFileType != "GIF")) { 
    echo "Sorry only GIF files are allowed."; 
    $uploadOk = 0; 
    } 
    // Check if $uploadOk is set to 0 by an error 
    if ($uploadOk == 0) { 
    echo "Sorry, your file was not uploaded."; 
    } else { 
    if (move_uploaded_file($_FILES["fileToUpload"]["tmp_name"], $target_file)) { 
     echo "The file ". basename($_FILES["fileToUpload"]["name"]). " has been uploaded."; 
     header('Location:field_medal_winner.php'); 
    } else { 
     echo "Sorry, there was an error uploading your file."; 
    } 
    } 
}
