使用Cookie在刷新时更改php中的标题
[英]changing title in php on refresh using cookies
问题描述
while ($row = mysql_fetch_row($result))
{
echo "<tr>";
echo ("<p><td>$row[2]</td><td>$row[0]</td><td>$row[1]</td><td><i>$row[3]</i></td><td><a href=\"delete.php?time=$row[2]&user=$row[0]&pass=$row[1]\"><center>[x]</center></a></td></p>");
echo "</tr>";
$x++;
}
echo "</table>";
}
else
{
echo "*No Accounts*";
}
if (isset($_COOKIE['amountx'])) {
if ($_COOKIE['amountx'] < $x) {
$x = $x - $_COOKIE['amountx'];
echo "<title>'New Logs - ($x)'</title>";
}
else if ($_COOKIE['amountx'] == $x) {
echo "<title>'Logs (0)'</title>";
}
else {
setcookie("amountx", $x, time() + 60 * 60 * 24 * 30);
}
}
else {
setcookie("amountx", $x, time() + 60 * 60 * 24 * 30);
}
The title never updates but the cookie is saved. 
标题永不更新，但cookie已保存。 This was in the while loop but I took it out and it still saves the cookie amount. 这是在while循环中，但是我取出来了，它仍然节省了cookie的数量。 But I can't get it to display the new title even after refreshing every 5 seconds via meta-refresh. 但是即使通过meta-refresh每5秒刷新一次，我也无法显示新标题。 How can I update the title? 如何更新标题？

Looking at the structure of your code, it appears that you're printing HTML in the <body> tag before you're attempting to echo a different <title> tag. 查看代码的结构，您似乎在尝试回显其他<title>标签之前在<body>标签中打印HTML。
You can't have a <title> tag anywhere but within the <head> element. 除了<head>元素之外，您在任何地方都没有<title>标签。
Move your <title> code to take effect within the <head> element, and it should work. 移动您的<title>代码，使其在<head>元素内生效，并且应该可以正常工作。

我删除了页面顶部的顶部<title>Page title</title> ，现在可以正常使用了，谢谢。
