自定义字段多值、Wordpress、PHP

自定义字段多值、Wordpress、PHP,php,wordpress,Php,Wordpress,我对php还不熟悉,但我一直在努力学习,我无法理解这一点 下面是我使用的一个值的原始代码: $description = get_post_meta($post->ID, "description", false); if ($description[0]=="") { <!-- If there are no custom fields, show nothing --> } else { <div class="wrap"> <h3&

我对
php
还不熟悉,但我一直在努力学习,我无法理解这一点

下面是我使用的一个值的原始代码:

$description = get_post_meta($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>

 } 
$description=get\u post\u meta($post->ID,“description”,false);
如果($description[0]==“”){
}否则{
产品
foreach($description作为$description){
回显“”.$description.“

”; } }
我很难修改这段代码,从多个自定义字段输入中检索值,并将其放在一起或在同一个字段之间

下面是添加了一个以上值的代码,但我不知道如何组合这两个值:

$description = get_post_meta($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>

 } 
$description=get\u post\u meta($post->ID,“description”,false);
$second\u value=get\u post\u meta($post->ID,“price”,false);
如何在此处组合两个值?
产品
//此部分如何工作以及如何在此处组合两个值?
} 
也许这里有人有一个很好的sajt技巧来回答我上面的问题?

试试这个

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

// Combine two values and print them


} else {

// Value is not set

}
