Php将图像上载到服务器

Php将图像上载到服务器,php,image,forms,oop,get,Php,Image,Forms,Oop,Get,我在尝试将图像上载到服务器时遇到了一点问题。 以下是我遇到的错误: 注意:未定义的索引:$this->file in/opt/lampp/htdocs/xampp/php/theislan_testdatabase/addItem.php,位于第70行 注意:未定义的索引:$this->file in/opt/lampp/htdocs/xampp/php/theislan_testdatabase/addItem.php,位于第71行 注意:第72行的未定义索引:$this->file in/o

我在尝试将图像上载到服务器时遇到了一点问题。 以下是我遇到的错误:

注意:未定义的索引:$this->file in/opt/lampp/htdocs/xampp/php/theislan_testdatabase/addItem.php,位于第70行

注意:未定义的索引:$this->file in/opt/lampp/htdocs/xampp/php/theislan_testdatabase/addItem.php,位于第71行

注意:第72行的未定义索引:$this->file in/opt/lampp/htdocs/xampp/php/theislan_testdatabase/addItem.php

我想问题出在这个类的构造函数中

public function __construct() {

        $this->submit  = isset($_GET['submit'])? 1 : 0;
        $this->errors = array();
        //$this->product_id = $this->filter($_GET['product_id']);
        $this->name = $this->filter($_GET['name']);
        $this->description = $this->filter($_GET['description']);
        $this->cost = $this->filter($_GET['cost']);
        $this->numinstock = $this->filter($_GET['numinstock']);
        //$this->picture = $this->filter($_GET['picture']);
        $this->type = $this->filter($_GET['type']);
        $this->file = $_GET['file'];
        $this->token = $_GET['token'];
    }
准确地说,这一行:$This->file=$\u GET['file']

这是那个类给我错误的部分

        public function addNew() {
       


   $databaseinst = database:: getinstance();
   $conn =   $databaseinst->connect();
   
   
   

   $query = "INSERT INTO  Product (name , description, cost, numinstock, type, image)  VALUES ('$this->name', '$this->description',  
   '$this->cost','$this->numinstock', '$this->type', 'images/$this->name')";
        //description = '$this->description' cost = '$this->cost' numinstock = '$this->numinstock' picture = '$this->picture' type = '$this->type'
   $result = $databaseinst->querydb($query);
   
   $id = mysql_insert_id();
   
   //upload file
   if ((($_FILES['$this->file']["type"] == "image/gif")
   ||($_FILES['$this->file']["type"] == "image/jpeg")
   ||($_FILES['$this->file']["type"] == "image/pjpeg"))
   &&($_FILES['$this->file']["type"] < 40000000))
    move_uploaded_file($_FILES["$this->file"]["tmp_name"],"images/" . $id.".jpq");
   
   

       if ( false===$result ) {

            $errorno =mysqli_errno($conn);

             if ($errorno === 1062)
             {
     $this->errors[]= "this user already exists on the database. please try signing!";
             }
             else
             {
             $this->errors[]= "error creating new user 
             name = '$this->name' description = '$this->description' cost = '$this->cost' numinstock = '$this->numinstock' 
     type = '$this->type'
             ";
             }
    }

        
        if($conn == null)
        {
        $this->errors[] = "difficulty is being experienced connecting to the server. Please try again in a moment!";
        }
       
    }
公共函数addNew(){

其他的

这是我获取用户输入的地方:

                    <li><b><cart><form method = "get" action="">
                                        <?php
                                        printf("<input type=\"hidden\" name=\"MAX_FILE_SIZE\" value=\"4000000\" />");
      printf("<p>Name: <input type='text' name=\"name\" id=\"styled\";\"></p>");
      printf("<p>Type: <input type='text' name=\"type\" id=\"styled\";\"></p>");
      printf("<p>Picture: <input type=\"file\" name=\"file\" id=\"file\" \></p>");

      printf("<p>Number Instock: <input type='text' onkeypress='validate(event)' name=\"numinstock\" id=\"styled\";\"></p>");
                   printf("<p>Description: <textarea  rows=\"6\" cols=\"200\" name=\"description\" id=\"styled\";\"></textarea></p>");
                                        ?>

                                               /></p></form></cart></b></li>

  • 当文件用作索引时,不要在其周围加引号。

    哪些行是70、71和72?很抱歉,它们是:($U文件['$this->file'][“type”]=“image/gif”)|($U文件['$this->file'][“type”]=“image/jpeg”)|($U文件['$this->file'][“type”=“image/pjpeg”)))&($U文件['][“type”=“type”=“image/pjpeg”)&$<40000000))尝试用单引号更改双引号?=>$_文件['$this->file']['type']如果你删除它,如果检查是否有效?否,我得到:未定义的索引:bg_3_02.jpg in/opt/lampp/htdocs/xampp/php/theislan_testdatabase/addItem.php,在第69行,该行是:move_上传的_文件($this->file“[“tmp_name”],“images/“$id.”.jpq”);
