Question

这是我的代码，它包含与数据库的连接：

session_start();

require 'config2.php';
require_once 'user.class.php';

$target = "uploads/"; 
$target1 = "uploads/"; 
$target = $target . basename( $_FILES['photo']['tmp_name']); 
$target1 = $target1 . basename( $_FILES['photo1']['tmp_name']); 

//This gets all the other information from the form 
$login = $_SESSION['login'];    
$name=$_POST['name']; 
$name1 =$_POST['name1'];
$pic=($_FILES['photo']['name']); 
$pic1=($_FILES['photo1']['name1']); 

$id=$_SESSION['id'];

// Connects to your Database 
print_r($_POST);
print_r($_FILES);
print_r($_SESSION);
print_r($_GET);

//$op = mysql_query("select id from users where id = '$id' ");
//Writes the information to the database 
mysql_query("INSERT INTO users (name, photo, name1, photo1) VALUES ('$name', '$photo', '$name1', '$photo1') where login = '$login'") ; 

// mysql_query("UPDATE users SET name='$name', photo = '$pic', name1 = '$name1', photo1 = '$pic1' WHERE  login = '$login' ");
//Writes the photo to the server 
if(move_uploaded_file($_FILES['photo']['tmp_name'] ,$target) )
{ 
  //Tells you if its all ok 
  echo "The file ". basename( $_FILES['uploadedfile']['name'] ). " has been uploaded,        and your information has been added to the directory"; 
  echo "<a href = 'profile.php?id=$id'>back</a>"; 
} 

if(move_uploaded_file($_FILES['photo1']['tmp_name'] ,$target1) )
{ 
  //Tells you if its all ok 
  echo "The file ". basename( $_FILES['uploadedfile']['name1'] ). " has been uploaded, and your information has been added to the directory"; 
  echo "<a href = 'profile.php?id=$id'>back</a>"; 
} 
else { 
  //Gives and error if its not 
  echo "Sorry, there was a problem uploading your file."; 
}

此代码仅适用于一个图像（将一个图像名称上传到数据库字段-photo），并且仅当我将插入更改为更新时。如何使用多个图像和insert命令？

Answer 1

输入以逗号分隔的行列表。

INSERT INTO users (name, photo, name1, photo1) 
VALUES 
('$name', '$photo', '$name1', '$photo1'),
('$name', '$photo3', '$name2', '$photo4'),
('$name', '$photo5', '$name3', '$photo6');

Answer 2

查看您的索引和变量名称。您使用$_FILES['uploadedfile']['name1']和$_FILES['photo1']['tmp_name']。你确定这是正确的吗？ POST数据位于$_POST数组中，文件信息位于$_FILES。上传文件的名称位于$_FILES['photo1']['name']。您永远不会设置$_FILES['uploadedfile']['name1']。

另外，你有什么表结构？你有两个名字字段和两个文件路径字段吗？

您的查询不正确。如果要更新表行，请使用UPDATE ... WHERE ...查询。如果您想添加新的，请使用INSERT而不是WHERE。您已对此进行了评论。

另外，确实使用PDO和准备好的语句。您的代码允许SQL注入。
