这条线怎么样？

警告：copy（）：open_basedir限制生效。 File（）不在允许的路径中：（/ xxx / xxx / xxx / xxx / php：/ tmp）在第85行的/home/xxxxxxxxxx/public_html/newsp.php中

这是我的代码：

<?php
 session_start();
 if (isset($_SESSION['password'])) {
        $con=mysqli_connect("xxxxx","xxxxx","xxxxx","xxxxx");
        // Check connection
            if (mysqli_connect_errno($con))
            {
            echo "Failed to connect to MySQL: " . mysqli_connect_error();
            }
            $result = mysqli_query($con,"SELECT * FROM News ORDER BY ID DESC LIMIT 1");

            while($row = mysqli_fetch_array($result))
                {
                    $ID = $row['ID'] + 1;
                }

            $title = $_POST['title'];
            $content = $_POST['content'];
            $type=$_POST['type'];

            echo $title . "<br>";
            echo $content . "<br>";
            echo $type . "<br>";
            echo $ID . "<br>";

            $sql = 'INSERT INTO News '.'(Title, Content, Type) '.'VALUES ( $title, $content, $type)';
            $result=mysqli_query($con,$sql);

//define a maxim size for the uploaded images in Kb
 define ("MAX_SIZE","100"); 

//This function reads the extension of the file. It is used to determine if the file  is an image by checking the extension.

         $i = strrpos($str,".");
         if (!$i) { return ""; }
         $l = strlen($str) - $i;
         $ext = substr($str,$i+1,$l);
         return $ext;
 }

//This variable is used as a flag. The value is initialized with 0 (meaning no error  found)

我想将图片上传到我的文件夹。

Answer 1

尝试使用move_uploaded_file(param1,param2);功能

move_uploaded_file($_FILES['image']['tmp_name'],$newname)

注意：您的变量$ newname必须包含应保存文件夹的路径+文件名

为您的INSERT QUERY

尝试在声明应插入字段

时删除'.'

产生您的查询

$sql= "INSERT INTO News(Title, Content, Type)VALUES ( '$title', '$content', '$type')";

因为'.'使你的sql失败。

无法使用php上传图像文件
