这是我的数据库连接代码我不知道为什么它没有将注册表单数据存储在数据库中，而只是显示一些空白页面
我尝试了很多次但它不起作用请帮我找出错误：
<?php
以下是数据库连接：
$host = "localhost"; // Host name
$username = "root"; // Mysql username
$password = ""; // Mysql password
$db_name = "project"; // Database name
连接到服务器并选择数据库：
mysql_connect("$host", "$username", "$password") or die("cannot connect");
mysql_select_db("$db_name") or die("cannot select DB");
检查图像类型并从表单中获取图像：
if (isset($_POST['submit'])) {
$target = "../uploads/";
$allowedExts = array("jpg", "jpeg");
$value = explode(".", $_FILES["file_upload"]["name"]);
$extension = strtolower(array_pop($value));
//$extension = end(explode(".", $_FILES["file_upload"]["name"]));
$target = $target . basename($_FILES['file_upload']['name']);
//$date = date("Y-m-d H:i:s");
//Function to generate image thumbnails
function make_thumb($src, $dest, $desired_width) {
/* read the source image */
$source_image = imagecreatefromjpeg($src);
$width = imagesx($source_image);
$height = imagesy($source_image);
/* find the "desired height" of this thumbnail, relative to the desired width */
$desired_height = floor($height * ($desired_width / $width));
/* create a new, "virtual" image */
$virtual_image = imagecreatetruecolor($desired_width, $desired_height);
/* copy source image at a resized size */
imagecopyresampled($virtual_image, $source_image, 0, 0, 0, 0, $desired_width, $desired_height, $width, $height);
/* create the physical thumbnail image to its destination with 100% quality */
imagejpeg($virtual_image, $dest, 100);

答案 0 :(得分：0)
在处理上传时，您应该始终使用文件的路径而不是相对路径。
$target = "../uploads/";
它应包含文件夹的路径，因为这是执行命令的脚本的相对路径。 （根据目标文件夹的确切位置，这样的东西。）
$target = $_SERVER['DOCUMENT_ROOT'].'/uploads/';
此外，此文件也应具有路径：
$destination = $_SERVER['DOCUMENT_ROOT']."/thumbnails/thumb_" . $maxId . $ext . "";
此外，这不应包含@符号，它应该是文件的名称，因此您可以从$_FILES数组中提取它：
$pimg = $_FILES['file_upload']['name'];
对于测试，您可以打印$_FILES数组的输出，以确保在更改后问题仍然存在时捕获正确的数组键（索引）字段。由于未定义的索引错误意味着您尝试提取的值不在数组中。
print_r($_FILE);
