如何在超链接中显示PHP变量？
如何在超链接中显示PHP变量？
提问于 2014-07-04 22:37:10
我试图回显一个变量，以便它显示在我的超链接中。以下是我的当前代码：
<?php
if (!defined("WHMCS"))
die("This file cannot be accessed directly");
$customerserviceid = mysql_query("SELECT id FROM `tblhosting` WHERE `userid` = '{$_SESSION['uid']}'");
function limitOrders($vars) {
if(mysql_num_rows(mysql_query("SELECT packageid FROM `tblhosting` WHERE `userid` = '{$_SESSION['uid']}'")) > 0) {
if($packageid = '1' || $packageid = '2' || $packageid = '3' || $packageid = '4' || $packageid = '5' || $packageid = '6' || $packageid = '7' || $packageid = '8' || $packageid = '9' || $packageid = '10') {
global $errormessage;
$errormessage = "<li>It looks like you already have an account! Please <a href='http://mywebsite.com/upgrade.php?type=package&id=$customerserviceid'>click here</a> to upgrade or downgrade your account.</li>";
}
}
}
add_hook("ShoppingCartValidateCheckout", 1, "limitOrders");
?>我尝试将$customerserviceid添加到第14行的URL中，但它只是显示为空白，所以我猜我没有正确地添加一些内容。当我在phpMyAdmin中运行查询时，它确实显示了我想要的内容，所以查询本身应该是正确的。

mysql_query返回一个资源。您需要从资源中获取数据。你可以这样做。
$result= mysql_query("SELECT id FROM `tblhosting` WHERE `userid` = '{$_SESSION['uid']}'");
$row = mysql_fetch_assoc($result);
$customerserviceid = $row['id'];这应该能行。
