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

问题描述

 < 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）保存在指定的路径时...如果我想保存一些想要的名字的文件....

我已经试过取代这个

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

用这个

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

但它不工作

解决方案

您可以试试这个，

$ p $ $ c $ pathinfo（$ _ FILES ['userFile'] [ '名称']）;
$ ext = $ info ['extension']; //获取文件的扩展名
$ newname =newname。。$ ext;

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

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 );
?>

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

i have tried replacing THIS

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

WITH THIS

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

BUT it's not working

解决方案

You can try this,

$info = pathinfo($_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);
