有没有办法混合使用CSS和PHP? [英] Is there a way to mix CSS and PHP?

问题描述

我正在研究wordpress主题，并且我希望有一个自定义标题背景.我曾经使用wordpress提供的 add_theme_support('custom-header); 函数，它可以工作，但不是我想要的.我想要背景图片而不是img.我创建了一个名为header_background_callout()的函数，并添加了一个部分，设置和控件.该功能起作用，并输出用户通过wordpress中的定制"部分选择的背景网址.有没有办法我可以在CSS中做类似的事情?: background-image:url(<?php echo wp_get_attachment_url(<?php get_theme_mod());?>);

I'm working on a wordpress theme, and i want to have a custom header background. I used to use add_theme_support('custom-header); function that wordpress offers, it works but not the way i want it to. I want to have a background-image instead of an img. I made a function called header_background_callout() and i added a section, setting and control. the function works and outputs the background url that the user chooses through the customize section in wordpress. Is there a way that i can do something like this in css? : background-image: url(<?php echo wp_get_attachment_url(<?php get_theme_mod()); ?>);

谢谢.

推荐答案

是的.
我将css文件制成了php文件，因此，我可以按照您所说的做

Yes kind off.
I made my css file a php file and because of that I can do as you say

background-image: url(<?php echo get_theme_mod(); ?>); // I suppose you need to echo the mod?

在HTML中，您可以像这样使用它；

In the HTML you use it like;

<Link rel="stylesheet" type="text/css" href="style.php">

编辑，您可能需要通过以下方法将php文件的标头更改为css文件:

Edit you may need to change the header of the php file to a css file by:

<?php header("content-type: text/css; charset: UTF-8"); ?>
