如何在本地主机上保存上传的文件？ [英] How to save an uploaded file on localhost?

问题描述

我一直使用从HTML5 / JS上载图像文件，并使用PHP脚本将其保存在本地主机（/ var / www /），但我不能保存它。当_FILES对象中存在对象时，函数move_uploaded_file总是返回false。我是一个PHP的新手：

  $ target =upload /; 
 if（！empty（$ _ FILES））
 {
 if（move_uploaded_file（$ _ FILES ['image_file'] ['tmp_name']，$ target））
 {
回显文件。 basename（$ _FILES ['image_file'] ['name']）。 已上传...; 
 
 else {
 echo对不起，上传文件出现问题。{$ error}; 
} 
} 
 else 
 {
 echo_files is empty; 
 
  

解决方案

b
$ b

  move_uploaded_file（$ _ FILES ['image_file'] ['tmp_name']，$ target。$ _ FILES ['image_file'] ['name']） 
  

因为您需要指定文件的名称，而不仅仅是目录。
$ b

请参阅 PHP文档中的示例

 <？php 
 $ uploads_dir ='/ uploads'; （$错误== UPLOAD_ERR_OK）{
 $ tmp_name = $ _FILES [ 图片] [ tmp_name的值] [$关键] 
 $ name = $ _FILES [pictures] [name] [$ key]; 
 move_uploaded_file（$ tmp_name，$ uploads_dir / $ name）; 
} 
}

I have been using to upload an image file from HTML5/JS and using PHP script to save it in localhost(/var/www/) but i cant save it. the function move_uploaded_file always returns false while there is exists an object in _FILES object. I am a newbie in php:

  $target = "upload/";
  if(!empty($_FILES))
  {
     if(move_uploaded_file($_FILES['image_file']['tmp_name'], $target)) 
     {
     echo "The file ". basename( $_FILES['image_file']['name']). " has been uploaded...";
     } 
     else {
     echo "Sorry, there was a problem uploading your file. {$error}";
     }
  }
  else
  {
    echo "_files is empty";
  }

解决方案

Try

move_uploaded_file($_FILES['image_file']['tmp_name'], $target.$_FILES['image_file']['name'])

Because you need to specify the name of file, not only the directory.

See example from PHP documentation

<?php
$uploads_dir = '/uploads';
foreach ($_FILES["pictures"]["error"] as $key => $error) {
    if ($error == UPLOAD_ERR_OK) {
        $tmp_name = $_FILES["pictures"]["tmp_name"][$key];
        $name = $_FILES["pictures"]["name"][$key];
        move_uploaded_file($tmp_name, "$uploads_dir/$name");
    }
}
?>
