CSS中的PHP变量不起作用 [英] PHP Variables in CSS not working
问题描述
我的html文件具有以下代码:
I have the following code for my html file:
<html>
<head>
<link rel='stylesheet' href='css/style.php' media = "screen"/>
</head>
<body>
<h1 id="foo">My h1 foo element</h1>
</body>
<html>
对于我的php文件:
<?php
header("Content-type: text/css; charset: UTF-8");
$asd = '#0000ff';
?>
h1#foo {
color: <?php echo $asd;?>;
}
我已经遵循了一些教程，这是我可以做的最简单的教程，但是某种程度上输出结果并没有达到应有的效果.我有什么想念吗?
I've followed some tutorials and this is the simplest one i could make but somehow the output is not working the way it should be. Did i miss anything?
P.S.如果我要在CSS中使用php变量，是否可以动态化?我的意思是在php主体内部，我可以覆盖css中使用的php变量的值，并且输出会改变吗?
P.S. if i was gonna use php variables in css, can it be sort of dynamic? i mean inside the php body, can i overwrite the value of the php variable used in css and the output would change?
非常感谢您的帮助！
推荐答案
对我来说很好^^
使用以下语法:
cssman.php
<?php
ob_clean();
header('Content-Type: text/css');
header('Cache-Control: no-cache, must-revalidate');
error_reporting( 0 );
// These are just to show you can use dynamic values and such:
$type = isset($_GET['type']) ? $_GET['type'] : '';
$theme = isset($_GET['theme']) ? $_GET['theme'] : '';
/** Simply print or echo your css here **/
ob_end_flush();
?>
首先尝试浏览输出，方法是手动导航到.php文件.如果根本没有内容，则很可能是PHP代码有错误，为了进行调试，您可以添加错误报告功能(别忘了也要ini_set('display_errors'，1)，否则错误只会被记录).
Try your output first, by navigating to the .php file manually. If there is no content at all, there is most likely a mistake in the PHP code, for debugging you could add error repporting (don't forget to also ini_set('display_errors',1), else errors will only be logged).
然后将其添加到您的视图中:
Then add it to your view:
您的视图
<style type="text/css">
@import "/Library/Stylesheets/cssman.php?type=cms" screen;
/* any aditional files here aswell */
</style>
