Question: Is it somehow possible to get_post_meta or get_post_custom and have meta_id returned along with the meta_value?
Solution:
<span class="hljs-function"><span class="hljs-keyword">function</span> <span class="hljs-title">get_complete_meta</span>(<span class="hljs-params"> <span class="hljs-variable">$post_id</span>, <span class="hljs-variable">$meta_key</span> </span>) </span>{
<span class="hljs-keyword">global</span> <span class="hljs-variable">$wpdb</span>;
<span class="hljs-variable">$mid</span> = <span class="hljs-variable">$wpdb</span>-><span class="hljs-title function_ invoke__">get_results</span>( <span class="hljs-variable">$wpdb</span>-><span class="hljs-title function_ invoke__">prepare</span>(<span class="hljs-string">"SELECT * FROM <span class="hljs-subst">$wpdb</span>->postmeta WHERE post_id = %d AND meta_key = %s"</span>, <span class="hljs-variable">$post_id</span>, <span class="hljs-variable">$meta_key</span>) );
<span class="hljs-keyword">if</span>( <span class="hljs-variable">$mid</span> != <span class="hljs-string">''</span> )
<span class="hljs-keyword">return</span> <span class="hljs-variable">$mid</span>;
<span class="hljs-keyword">return</span> <span class="hljs-literal">false</span>;
}
it will return an array of objects like:
<span class="hljs-title function_ invoke__">Array</span>
(
[<span class="hljs-number">0</span>] => <span class="hljs-built_in">stdClass</span> <span class="hljs-title function_ invoke__">Object</span>
(
[meta_id] => <span class="hljs-number">1002</span>
[post_id] => <span class="hljs-number">1</span>
[meta_key] => my_key
[meta_value] => my_value
)
[<span class="hljs-number">1</span>] => <span class="hljs-built_in">stdClass</span> <span class="hljs-title function_ invoke__">Object</span>
(
[meta_id] => <span class="hljs-number">1003</span>
[post_id] => <span class="hljs-number">668</span>
[meta_key] => my_key
[meta_value] => another value
)
)
