我在将变量设置为 echo<<<_END 构造中的链接时遇到问题
这是我的代码:
<?php //submit_build.php
include_once 'header.php';
require_once 'login_builds.php';
include_once 'functions.php';
$db_server = mysql_connect($db_hostname, $db_username, $db_password);
mysql_select_db($db_database)
or die("Unable to select database: " . mysql_error());
?>

我遇到问题的代码行是第 236 行,在代码底部附近以粗体显示。
这个:
<td class="newsbody" style="width:40%"><a href="view_build.php?buildname=$row[5]">$row[0]</a></td>
我基本上希望搜索结果显示一个值,例如“Dual Broncos”,然后在链接到 view_build.php?buildurl=Dual+Broncos 的文本周围有一个超链接。
我不知道如何正确插入 urlencode 函数,因为当我放置标签时,它说我的 HTML 错误(它说表格列结束标签无效/不必要)。
所以我尝试在数据库输入时让 urlencode 工作,这样每个对象都有一个“buildname”和一个“buildurl”,其中 buildurl = urlencode($buildname)。此代码有效,并且我的数据库输入了值“Dual+Broncos”,但是当我检索该行以将其放入位置 view_build.php?buildurl=$row[5] 的链接中时,它不显示'+' 应该在编码的 URL 中。
这个有什么帮助吗?或者关于如何以另一种方式执行此功能的建议?
非常感谢!
PS。我包含了我的整个代码,以便您可以看到 HTML 标记和 PHP 标记的开始和结束位置。
