「if meta box empty」將它從前端隱藏 - WordPress

Question

我在前端顯示郵件和電話的值。

如何非此即彼設置隱藏到javascript:void(0)

這是我當前的代碼：

section id="page-content" class="col-md-8"> 
        <h3>About <?php the_title(); ?></h3> 
         <ul class="people-single unstyled inline-block"> 
           <li><a href="mailto:<?php echo(types_render_field("person-email", array('raw' => true))) ; ?>" target="_blank" class="hvr-hang"><span class="glyphicon glyphicon-envelope" aria-hidden="true"></span></a></li> 
           <li><a href="tel:<?php echo(types_render_field("person-phone", array('raw' => true))) ; ?>" target="_blank" class="hvr-hang"><span class="glyphicon glyphicon-earphone" aria-hidden="true"></span></a></li> 
         </ul> 
         <?php the_content(); ?> 
       </section> 

Answer 1

像這樣的東西應該工作：

<?php 
$personalEmail = types_render_field("person-email", array('raw' => true))); 
$personalPhone = types_render_field("person-phone", array('raw' => true))); 
?> 
<ul class="people-single unstyled inline-block"> 
    <?php 
    if($personalEmail != "") 
    { ?> 
     <li><a href="mailto:" target="_blank" class="hvr-hang"><span class="glyphicon glyphicon-envelope" aria-hidden="true"></span></a></li> 
    <?php 
    } 
    if($personalPhone != "") 
    { ?> 
     <li><a href="tel:" target="_blank" class="hvr-hang"><span class="glyphicon glyphicon-earphone" aria-hidden="true"></span></a></li> 
    } ?> 
</ul> 

如果電子郵件或電話號碼不是空白，那麼它會顯示電話號碼或電子郵件。
