自定义字段多个值,Wordpress,PHP

我是php的新手,但努力学习,我无法弄明白。

这里的原始代码带有一个值我正在工作:

$description = get_post_meta($post->ID, "description", false);

if ($description[0]=="") { 

<!-- If there are no custom fields, show nothing -->

 } else { 

<div class="wrap">
    <h3>Products</h3>

     foreach($description as $description) {
    echo '<p>'.$description.'</p>';
    } 

</div>

 } 

我很难修改此代码,以便从多个自定义字段输入中检索值并将它们放在一起并放在一起。

以下是添加了一个值的代码,但是如何组合thoose 2值:

$description = get_post_meta($post->ID, "Description", false);
$seccond_value = get_post_meta($post->ID, "price", false);

<?php
if ($description[0]=="") {  
?>
<strong> how do i combine 2 values here?</strong>


<!-- If there are no custom fields, show nothing -->
<?php
 } else { 

?>
<div class="wrap">
    <h3>products</h3>


<strong>// how does this part work and how to i combine 2 values here?</strong>
<?php
     foreach($description as $description) {
    echo '<p>'.$description.'</p>';
    }  
?>
</div>

 } 

也许这里的某个人有一个很好的提示,可以解决上面的问题吗?

试试这个

if ($description[0] != "" && $seccond_value[0] != "") { 

// Combine two values and print them


} else {

// Value is not set

}
