如何上传 &使用所需名称保存文件 [英] How to upload & Save Files with Desired name

问题描述

我正在使用此代码上传文件(图像到文件夹)

i am using this code to upload files(images to a folder)

<form action='' method='POST' enctype='multipart/form-data'>
<input type='file' name='userFile'><br>
<input type='submit' name='upload_btn' value='upload'>
</form>

<?php
$target_Path = "images/";
$target_Path = $target_Path.basename( $_FILES['userFile']['name'] );
move_uploaded_file( $_FILES['userFile']['tmp_name'], $target_Path );
?>

当文件(图像)保存在指定路径时......如果我想用某个想要的名称保存文件怎么办......

when the file(image) is saved at the specified path... WHAT if i want to save the file with some desired name....

我试过替换这个

$target_Path = $target_Path.basename( $_FILES['userFile']['name'] );

有了这个

$target_Path = $target_Path.basename( "myFile.png" );

但它不起作用

推荐答案

你可以试试这个，

$info = pathinfo($_FILES['userFile']['name']);
$ext = $info['extension']; // get the extension of the file
$newname = "newname.".$ext; 

$target = 'images/'.$newname;
move_uploaded_file( $_FILES['userFile']['tmp_name'], $target);
