搜索结果页面-显示自定义元字段

时间：2014-05-14 作者：user12920

对于搜索结果页面，我正在制作一个自定义模板。在这个自定义模板中，我想显示自定义元字段值。

但是，当我这样做时：

    <?php if ( have_posts() ) : ?>

        <?php /* Start the Loop */ ?>
        <?php while ( have_posts() ) : the_post(); ?>

            <?php
            $pName = get_post_meta($post->ID, $productName, \'true\');
            echo $pName;
 );
    ?>
        <?php endwhile; ?>

        <?php else : ?>
            <?php get_template_part( \'content\', \'none\' ); ?>

    <?php endif;
我得到的结果不是自定义字段的值，而是：

Array
当我var\\u转储$pName时，它会显示所有正确的自定义字段内容。

问：为什么我会得到一个数组作为结果（当我告诉它这是一个带有“true”的单一结果时），我如何修复它以使它显示正确的内容？

谢谢

var\\u dump（$pName），设置为true：

---更新#2---

如果有什么区别的话：im想要的元数据来自一个CPT（产品）中的帖子（但我使用“搜索一切”插件将CPT包含在标准搜索结果中）

--找到了--

好吧，我犯了一个很愚蠢的错误。

$productName不应是变量。它应是字段的实际名称，即：productName。

所以做出这样的改变解决了所有的问题。

哈哈。。美好时光：）

谢谢大家的帮助！

你有一个失踪的) 您将true作为字符串传递，而不是布尔值。所以这一行：

$pName = get_post_meta($post->ID, $productName, \'true\';
事实上应该是：

$pName = get_post_meta($post->ID, $productName, true);
根据您的更新，为什么不执行以下操作：

echo \'Product Name: \'. $pName[\'productName\'][0];
echo \'Location: \'. $pName[\'locationName\'][0];
echo \'Address: \'. $pName[\'locationAddress\'][0];
然而，这段代码需要改进，可能是stackoverflow的一个问题，因为它不是WordPress特有的。这是PHP，处理数组/多维数组

SO网友:Howdy_McGee

我假设您的meta\\u数据是一个序列化数组。下面是get_post_meta() 文档介绍了序列化阵列：

$single
（布尔）（可选）如果设置为true，则函数将以字符串形式返回单个结果。如果为false或未设置，则该函数返回一个自定义字段数组。在序列化数组的上下文中，这可能不是直观的。If you fetch a serialized array with this method you want $single to be true to actually get an unserialized array back. 如果传入false或不传入，则将有一个1的数组，索引0处的值将是序列化字符串。

因此，如果您想要返回一个实际的单个值，则必须逐个保存每个元，而不是将元作为一个数组完全更新。要访问这些值，可以使用foreach 或者通过从0开始的索引直接访问它们。
