Question

我真的需要你的帮助。我试图用PHP代码上传图像。当我使用不同的.php文件只有上传代码时，它可以工作，但是当我尝试添加到我的主代码中时，我将这些信息发布到数据库中。

我添加了这个，正如我所说，它仅适用于上传的单独代码。

form action="core/books-reg.php" method="POST" enctype="multipart/form-data"

这是我想要使其工作的主要.php代码。代码在！empty（描述）之后开始。数据库采用名称并放入mysql，但我的文件夹中没有文件。任何帮助或其他方法都会非常好。

<?php
session_start();

require("dbc.php");

$username = $_SESSION['username'];
$title = $_POST['title'];
$con = $_POST['con'];
$price = $_POST['price'];
$prodcode = $_POST['prodcode'];
$isbn = $_POST['isbn'];
$publisher = $_POST['publisher'];
$pages = $_POST['pages'];
$description = $_POST['description'];
$year = $_POST['year'];
$course = $_POST['course'];
$module = $_POST['module'];

if(!empty($title))
{
    if(!empty($price))
    {
        if(!empty($prodcode))
        {
            if(!empty($isbn))
            {
                if(!empty($publisher))
                {
                    if(!empty($pages))
                    {
                        if(!empty($description))
                        {
                            if (!isset($_FILES['image']['tmp_name'])) {
                            echo "";
                            }else{
                            $file=$_FILES['image']['tmp_name'];
                            $image= addslashes(file_get_contents($_FILES['image']['tmp_name']));
                            $image_name= addslashes($_FILES['image']['name']);

                            move_uploaded_file($_FILES["image"]["tmp_name"],"upload/" . $_FILES["image"]["name"]);

                            $location="upload/" . $_FILES["image"]["name"];             
                            }

                            mysql_query("INSERT INTO `books` (username,title,con,price,prodcode,isbn,publisher,pages,description,image,year,course,module) VALUES('$username','$title','$con','$price','$prodcode','$isbn','$publisher','$pages','$description','$image_name','$year','$course','$module')");
                            header("location: ../add_books.php?feedback=Your book has been put on the books page.");
                        }
                        else
                        {
                            header("location: ../add_books.php?feedback=Description field is empty");
                        }
                    }
                    else

Answer 1

如果您想将上传代码放在同一页面上，那么首先您不需要在action代码中指定form。

并检查路径upload/是否存在于正确的位置。

Answer 2

使用move_uploaded_file修复（$ _ FILES [＆＃34;图像＆＃34;] [＆＃34; tmp_name＆＃34;]，＆＃34; ../ upload /＆＃34;。$ _FILES [＆＃34 ;图像＆＃34;] [＆＃34;名称＆＃34;]）;
