我已经放置了一个用于获取当前页面 URL 的 php 代码，现在我可以通过编写此代码来获取当前页面 URL

<?php print(selfURL()); ?>

现在，我想知道如何将此代码编写为输入字段的默认值？实际上我希望输入字段自动填充当前页面的 URL。

当我使用它时<?php print(selfURL()); ?>，value="<?php print(selfURL()); ?>"它简单地显示一个文本并且不显示当前的 url。但是当我将它粘贴到其他地方时，它工作正常。

有什么建议么？

更新：

伙计们，这是页面的完整代码，可能有帮助！

<?php
function selfURL() { $s = empty($_SERVER["HTTPS"]) ? '' : ($_SERVER["HTTPS"] == "on") ? "s" : ""; $protocol = strleft(strtolower($_SERVER["SERVER_PROTOCOL"]), "/").$s; $port = ($_SERVER["SERVER_PORT"] == "80") ? "" : (":".$_SERVER["SERVER_PORT"]); return $protocol."://".$_SERVER['SERVER_NAME'].$port.$_SERVER['REQUEST_URI']; } function strleft($s1, $s2) { return substr($s1, 0, strpos($s1, $s2)); }
?>
<?php

require_once( dirname(__FILE__).'/includes/load-yourls.php' );

试试这个，

<input name="textVal" type="text" val=<?php echo selfURL(); ?> />

你可以像下面这样使用。

方法一

 <input name="myinput" type = "text" value = "<?php print(selfURL()); ?>" />

方法二

<input name="myinput" type = "text" value = "<?php echo selfURL(); ?>" />

问题更新后回答

<input type="text" name="" id="" value="<?php echo $_SERVER['PHP_SELF']; ?>"/>

以下是解决方案：

$_SERVER['PHP_SELF'];
测试代码如下

<input type="text" name="" id="" value="<?php echo $_SERVER['PHP_SELF']; ?>"/>

你的代码编辑

$var = $_SERVER['PHP_SELF'];
OR
$var = selfURL();

<p><label>URL: <input type="text" name="url" value="$var" size="70" /></label></p>

您在 her-doc 语法中添加 php，这就是错误
