【问题描述】：
一直在为我妻子的珠宝网站制作产品页面。我从教程中添加了 php 并尝试运行该页面。包括页眉在内的所有图像都没有与页脚一起出现。它们出现在每隔一页上。信息产品也没有出现。该页面显示连接已打开，我没有收到任何错误。导航与一些 css 一起显示，但仅此而已。
这是我正在使用的代码。
<?php
error_reporting(E_ALL);
ini_set('display_startup_errors', 1);
ini_set('display_errors', 1);
?>
<?php
if (isset($_GET['id'])) {
// Connect to the MySQL database
include_once("storescripts/connect_to_mysql.php");
$con =
mysqli_connect("$db_host","$db_username","$db_pass","$db_name");
if (mysqli_connect_errno()) {
printf("Connect failed: %s\n", mysqli_connect_errno());
exit();
} $id = preg_replace('#[^0-9]#i', '', $_GET['id']);
$sql = "SELECT * FROM products WHERE category='Bracelets';";
$result = mysqli_query($con, $sql);
$resultCheck = mysqli_num_rows($result);
if ($resultCheck > 0) {
// get all the product details
while($row = mysqli_fetch_assoc($result)); {
$item_number = $row["item_number"];
$price = $row["price"];
$desc = $row["description"];
$category = $row["category"];
}
} else {
echo "Data to render this page is missing.";
exit();
}
}
?>

【问题讨论】：
-
你在 html 部分的哪里定义了
$pid？ -
检查
include_once中的网址。它在同一个目录中吗？如果是，请不要使用像c:/xampp/htdocs这样的网址，您的页脚在哪里，我看不到您在 HTML 中包含的任何页脚 -
我昨晚在处理页脚部分时不小心取出了它。我重做了 php，页脚和导航出现了，但页眉仍然没有。它显示在 Dreamweaver 的查看器中。仍然无法获取产品信息。
-
$pid 是在将项目放入数据库时在 inventory_list 页面上定义的。它是图片id的变量。
