Hi there.<\/p>\n
I am trying to build a function in my theme which collects post metadata and displays them, according to what I write in the custom field. I want to show images representing flags (for countries). Some posts must have more than one flag displayed.
\nI thought the function get_post_custom_values would be nice.<\/p>\n
<?php get_post_custom_values($key, $post_id); ?> in my theme where I want the images to show up. For each post I create a custom field named flags, and type in values like uk,dk (etc).<\/p>\n
And this script to associate metadata to images:<\/p>\n
<? php
\n$uk=\/images\/uk-png;
\n$dk=\/images\/denmark.png;<\/p>\n
$mykey_values = get_post_custom_values(\u2018flags\u2019);
\nForeach ($mykey_values as $key => $value) {
\necho \u201c$key => $value (\u2018flags\u2019)\u201d;
\n}
\n?><\/p>\n
But it doesnt work.
