如何query_posts,并且仅在自定义字段不为空或具有值的情况下显示结果.

我想在自定义字段中输入URL,并且仅在存在URL时才显示这些页面?

当前代码,但我想不通:

$args = array( 'posts_per_page' => '10', 'post_type' => 'programmes', 'orderby' => 'meta_value_num', 'meta_key' => 'popularityfig', 'order' => 'DESC', );
How do I query_posts and only show results if a custom field is not empty or has a value.

I want to put in a URL in a custom field and only show these pages if there is a URL?

current code but I can't figure out the rest:

$args = array( 'posts_per_page' => '10', 'post_type' => 'programmes', 'orderby' => 'meta_value_num', 'meta_key' => 'popularityfig', 'order' => 'DESC', );

尚不清楚上面的答案是否真的对您有用@erichmond,但绝对不是我想要的.虽然找到了解决方案.请参阅:如何显示仅在meta_value不为空的情况下发布

It's not clear if the answer above actually worked for you @erichmond, but it definitely did not for me. Found a solution though. See: How can I show posts only if meta_value is not empty

尝试以下代码:

 $args = array(
'posts_per_page' => '10',
'post_type' => 'programmes',
'meta_key' => 'popularityfig',
'meta_value' => '',
'meta_compare' => '!=',
'order' => 'DESC'
);

您可能需要在代码中注意两个参数:meta_value和meta_compare.将meta_compare与运算符!=一起使用将排除元值为空的帖子.

Try this code:

$args = array(
'posts_per_page' => '10',
'post_type' => 'programmes',
'meta_key' => 'popularityfig',
'meta_value' => '',
'meta_compare' => '!=',
'order' => 'DESC'
);

There're 2 arguments you might want to note in the code: meta_value and meta_compare. Using meta_compare with operator != will exclude posts with empty meta value.

谢谢,我现在可以在法典上看到吗?为什么在不确定之前看不到它！！再次感谢.

Thanks, I can see that on codex now?? Why I couldn't see it before I'm not sure!! Thanks again.

无论出于何种原因,这都会使我的所有帖子变得毫无价值.取而代之的是,我使用了'meta_value'=> array('')和'meta_compare'=>'NOT IN'并成功了,我使用高级自定义字段(ACF)插件创建了元值,它只是一个文本字段.

For whatever reason, this kept pulling all of my posts regardless of value. Instead, I used 'meta_value' => array('') and 'meta_compare' => 'NOT IN' and that worked.I created my meta value with the Advanced Custom Fields (ACF) plugin and it was just a text field.
