Question

我在设置一个变量到我的echo＆lt;＆lt;＆lt;＆lt; _END construct

中的链接时遇到了问题

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，在代码底部附近加粗。

这一个：

<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”，然后在文本周围有一个链接到view_build.php的超链接？buildurl = Dual + Broncos。

我不知道如何正确插入urlencode函数，因为当我放置标记时，它表示我的HTML是错误的（它表示表格列结束标记无效/不必要）。

所以我试着让urlencode在数据库输入时工作，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，我的数据库输入了值“Dual + Broncos”，但是当我检索行将其放入view_build.php？buildurl = $ row [5]位置的链接时，它不会显示“+”应该在编码的URL中。

对此有何帮助？或者建议如何以另一种方式执行此功能？

非常感谢！

PS。我包含了我的整个代码，因此您可以看到HTML标记和PHP标记的开始和结束位置。

Answer 1

只需使用变量将编码值存储在之后插入的heredoc之前。

$value = urlencode($row[5]);
...
<td class="newsbody" style="width:40%"><a href="view_build.php?buildname=$value">$row[0]</a></td>

Answer 2

只需在循环外进行urlencoding：

for($j = 0; ...) {
   $encoded = urlencode($row[0]);
   echo <<<EOL

....?buildname=$encoded
EOL;
}

你可以使用变量函数和“内联”编码，例如

$enc = 'urlencode';
echo <<<EOL
 ... ?buildname={$enc($row[0])}
EOL;

但是这样的代码很快变得完全无法管理并且很难调试。
