PHP文件上传不读取$ _FILES ['image'] [英] PHP file uploads doesnot read $_FILES['image']

问题描述

我有这个输入类型

 < input class =btn btn-successtype =filename = profile_imagestyle =margin-top：10px; margin-left：20px;>< / input> 
  

用户将从这里添加图片文件，并将PHP代码上传到文件中

  if（isset（$ _ FILES ['profile_image']））
 {
 $ image_type = $ this-> getImageType（$ _ FILES [ 'profile_image']）; 
 
 if（$ image_type =='image'）
 {
 $ extension = pathinfo（$ _ FILES ['profile_image'] ['name']，PATHINFO_EXTENSION）; 
 $ filename ='123 _'。uniqid（）。'。'。$ extension; 
 move_uploaded_file（$ _ FILES ['profile_image'] ['tmp_name']，'../functions/images/images/'.$filename）; 
} 
} 
 else 
 {
 $ filename ='default_profile_image.jpg'; 
 
 
 
 $ p $  getImageType   
 
 $ p $  public function getImageType（$ file）
 {
 $ imageMime = getimagesize（$ file ['tmp_name ]）; 
 $ type = explode（'/'，$ imageMime ['mime']）; 
返回$ type [0]; 
 
 $ / code> 

但它不读取 $ _ FILES ['profile_image '] ，而是移动到其他部分。为什么不读取$ _FILES？


解决方案

在表单标签中添加此代码

enctype =multipart / form-data

 < form action =upload.phpmethod =postenctype =multipart / form-data> 
  




i have this input type

  <input class="btn btn-success" type="file" name="profile_image" style="margin-top:10px; margin-left:20px;"></input>

user will add the image file from here, and the PHP code to upload the file

if(isset($_FILES['profile_image']))
            {
                $image_type = $this->getImageType($_FILES['profile_image']);

                if($image_type == 'image')
                {
                    $extension = pathinfo($_FILES['profile_image']['name'], PATHINFO_EXTENSION);
                    $filename = '123_'.uniqid().'.'.$extension;
                    move_uploaded_file($_FILES['profile_image']['tmp_name'], '../functions/images/images/'.$filename);
                }
            }
else
            {
                $filename = 'default_profile_image.jpg';
            }

and the getImageType

public function getImageType($file)
    {
        $imageMime = getimagesize($file['tmp_name']);
        $type = explode('/', $imageMime['mime']);
        return $type[0];
    }

but it does not read $_FILES['profile_image'] and rather moves to else part. why does it not read $_FILES ? is there anything missing?

解决方案

add this code in form tag
enctype="multipart/form-data"

<form action="upload.php" method="post" enctype="multipart/form-data">
