Answer 1

$ _FILES数组具有特定的格式和布局，并且您的密钥（例如did）将不存在。标准布局是：

$_FILES = array(
    'name of your input type="file" field' => array(
          'name' => 'name of file on client machine',
          'type' => 'mime type of file, as provided by the client',
          'size' => 'size of uploaded file',
          'tmp_name' => 'name of server-side temporary file the upload was stored in',
          'error' => 'error code of upload operation'
    )
);

因此，$_FILES['photo']['did']将返回无效索引，因为_FILES数组中没有did元素。

数组结构和错误代码的完整详细信息分别为here和here。

SQL错误是由于您尝试运行查询两次。将查询字符串直接在mysql_query()函数调用中作为参数，稍后再使用未定义的$sql变量。

同样，您正在引用两个单独的文件上传：

$_FILES['photo']
$_FILES['uploadedfile']

在不同的地方。应该是哪一个？

第一条建议：绝不信任用户，总是验证和过滤输入

$did = filter_input(INPUT_POST, 'did');
$name = filter_input(INPUT_POST, 'dname');
$disc = filter_input(INPUT_POST, 'ddisc');
$price = filter_input(INPUT_POST, 'dprice');
$photo = (isset($_FILES['photo'])) ? $_FILES['photo'] : null;

然后，$_FILES['photo']和$sql不存在。 Allways使用isset()，empty() ...

测试存在

解决了大多数错误 - 仍然有一个

错误：

注意：未定义的索引：第33行的D：\ WEB \ Sites \ Restoraunt \ addDish.php中的上传文件该文件已上载，您的信息已添加到directoryError：您的SQL语法中有错误;检查与MySQL服务器版本对应的手册，以便在第1行的“资源ID＃2”附近使用正确的语法

代码：

[PHP]<?php
session_start();

//This is the directory where images will be saved
$target_path = "images/";
$target = $target_path . basename ($_FILES['photo']['name']);

$did = $_POST['did'];
$name = $_POST['dname'];
$disc = $_POST['ddisc'];
$price = $_POST['dprice'];
$pic=($_FILES['photo']['name']);

$con = mysql_connect("","restoraunt","123456"); // àéôä ùí äùøú ùìê, localhost àå îùäå?
if (!$con)
{
die('Could not connect: ' . mysql_error());
}

mysql_select_db("restoraunt", $con);

//Writes the information to the database
mysql_query("INSERT INTO `menu` VALUES ('$did', '$name', '$disc', '$price','a','$pic')") ;
