我的mySQL数据库已经满了<a> tags but the links are not working when echo&#39;ing

Question

$mydb = new wpdb('xxxxxx','xxxxx','xxxxx','localhost');
$max_id = $mydb->get_results("SELECT MAX(id) FROM `links1`");
$row_id = ceil((mt_rand() / mt_getrandmax()) * intval($max_id[0]->{"MAX(id)"}));
$row_pre = $mydb->get_results("SELECT link FROM `links1` WHERE id=" . $row_id);
$row = $row_pre[0]->link;

my rows contain anchor tags like this:

<a href="http://www.google.com">google</a>

But when this code runs, it only displays this in the browser:

 google

Link does not work. Why?

=========

Here's the code that's outputting the code:

<?php require_once('add.php'); ?>
            <p><?php echo $row; ?></p>

========= I've even tried doing this for testing purposes:

echo htmlspecialchars($row);

And it displays the raw anchor tags! Like this in the browser:

<a href="http://www.google.com">google</a>

++++++++++++++++++++++++

EDIT!!!!!

I looked at the outputted html in the browser through Chrome's dev tools and the slashes are missing in the link!!! WHY?

Answer 1

在google.com之前加上 http：// ：

<a href="http://www.google.com">google</a>

更新了查询：

选择链接时，您只需将http：//连接到您的链接，如下所示：

SELECT concat('http://',link) as link FROM `links1` WHERE id=" . $row_id

Answer 2

事实证明问题在于被提取的列包含ENTIRE锚链接。一旦我们将数据库更改为在一列中包含URL，并在另一列中包含链接名称，它就会起作用！

不确定原因......从列中提取整个锚链接可能是一个安全问题。
