如何根据自定义字段在WP帖子标题旁边添加图标

Question

I am trying to add a little icon (jpg) next to every WordPress posts' titles that have a specifc custom field. Anyone would know how to do it?

I have defined a custom field for some posts like this: $custom = 2 and i want these posts' titles to include an icon.

Answer 1

So to access the specific custom field, use this:

get_post_meta($post_id, $key, $single);

Where $post_id = the id of the post (use

$post->ID 

to get a post's ID)

Where $key = the name of the custom field (ie. "custom")

where $single = If set to true then the function will return a single result, as a string

So you'd use something like:

$key = 'custom';
if (get_post_meta($post->ID, $key, true) == 2){
    //echo icon here
}
