Question

我在PHP产品的第36行继续收到此错误，第36行是:(它是一个电子商务网站）

<?php
include '../inc/theprodukts.php';
?>

当我向下移动几行时，它会移动错误行，因此错误显然在我的theprodukts.php中，如下所示。

<?php
$CatID = $_GET['cat'];

$dbhost = "127.0.0.1";
$dbuser = "root";
$dbpass = "";
$db = "nettbutikk";

$con = mysqli_connect($dbhost,$dbuser,$dbpass,$db);
if (mysqli_connect_errno($con))
{
echo "Error: " . mysqli_connect_error();
}

if ($CatID == "all")
{
$checkproducts = mysqli_query($con,"SELECT * FROM products");

while($row = mysqli_fetch_array($checkproducts))
{


echo "<div class='produktboks'>";
echo "<p class='produktnavn'>" . $row['name'] . "</p>";
echo "<div class='photos'><img alt='' width='130px' height='90px' src='../bilder/produktbilder/" . $row['img'] . "' />";
echo "<p>pris : " . $row['price'] . " Kr</p>";
echo "<a href='../sider/productdetail.php?productid=" . $row['ID'] . "&?cat=" . $row['cat'] . "'><img src='../bilder/detaljer.gif' alt=''width='53' height='19'></a>";
echo "<a href='../inc/addtocart.php?productid=" . $row['ID'] . "'><img src='../bilder/cart.gif' alt='' width='71' height='19'></a>";
echo "<br>";
echo "<br>";
echo "</div>";
echo "</div>";
}
}else{
$checkproducts = mysqli_query($con,"SELECT * FROM products
WHERE cat=" . $CatID);

while($row = mysqli_fetch_array($checkproducts))
{
echo "<div class='produktboks'>";
echo "<p class='produktnavn'>" . $row['name'] . "</p>";
echo "<div class='photos'><img width='130px' height='90px' src='../bilder/produktbilder/" . $row['img'] . "' />";
echo "<p>pris : " . $row['price'] . " Kr</p>";
echo "<a href='../sider/productdetail.php?productid=" . $row['ID'] . "&?cat=" . $row['cat'] . "'><img src='../bilder/detaljer.gif' alt=''width='53' height='19'></a>";
echo "<a href='../inc/addtocart.php?productid=" . $row['ID'] . "'><img src='../bilder/cart.gif' alt='' width='71' height='19'></a>";
echo "<br>";
echo "<br>";
echo "</div>";
echo "</div>";

}
}
mysqli_close($con);
?>

Answer 1

echo "<a href='../sider/productdetail.php?productid=" . $row['ID'] . "&?cat=" . $row['cat'] . "'><img src='../bilder/detaljer.gif' alt=''width='53' height='19'></a>";

注意＆amp;在网址建设中。

将其更改为：

echo "<a href='../sider/productdetail.php?productid=" . $row['ID'] . "&amp;?cat=" . $row['cat'] . "'><img src='../bilder/detaljer.gif' alt=''width='53' height='19'></a>";

并且在while循环中也是如此。

HTML Validator未转义＆amp;这应该是放大器
