WordPress的背景图像在：后

Question

我如何做一个自定义字段的背景图像，这是在选择器后？ 问题是，我必须让它变回来

<div id="pr1" class="project-slide> 
    <span class="project-title"><?php echo $project_title2;?></span> 
    <p><?php echo $project_text2;?></p> 
</div> 


    div#pr0.project-slide:after{ 
    background-image: url(http://localhost/ruby/wp-content/uploads/2017/05/720_500_specialnij.png); 
    } 

Answer 1

试试这个。

<div id="pr1" class="project-slide> 
    <span class="project-title"><?php echo $project_title2;?></span> 
    <p><?php echo $project_text2;?></p> 
</div> 




div#pr1.project-slide:after{  
    content:url(http://localhost/ruby/wp-content/uploads/2017/05/720_500_specialnij.png); 
    } 

Answer 2

尝试这可能会为你工作，如果不是这应该是沿着这些路线的东西。

<?php 
$your_field = get_field('your_field'); 
?> 

<style> 
div#pr0.project-slide:after{ 
    background-image: url(<?php echo $your_field['url']; ?>); 
} 
</style>
