<p>You could store the gender inside a data value on the options of the select.</p>

<p>Like this:</p>

<p><div class="snippet" data-lang="js" data-hide="false">
<div class="snippet-code">
<pre class="snippet-code-js lang-js prettyprint-override"><code>$('#person').change(function(){
	var gender = $(this).find('option:checked').attr('data-gender');
    $('#gender_hidden').val(gender);
    $('#gender').val(gender);
});</code></pre>
<pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"&gt;&lt;/script&gt;
&lt;form&gt;
    &lt;input type="hidden" id="gender_hidden" /&gt;
    &lt;input type="text" id="gender" /&gt;
    &lt;select id="person" onchange="change(this);"&gt;
        &lt;option value="Person_1" data-gender="male"&gt;Person 1&lt;/option&gt;
        &lt;option value="Person_2" data-gender="female"&gt;Person 2&lt;/option&gt;
        &lt;option value="Person_3" data-gender="male"&gt;Person 3&lt;/option&gt;
    &lt;/select&gt;
&lt;/form&gt;</code></pre>
</div>
</div>
</p>

<p>To generate the HTML for that use <a href="https://developer.wordpress.org/reference/functions/get_post_meta/" rel="nofollow">get_post_meta</a></p>

<pre><code>&lt;?php
$args = array('post_type'=&gt;'people');

$people = WP_Query($args);
if ($people-&gt;have_posts()) ?&gt;
    &lt;input id="gender" name="gender" /&gt;
    &lt;select name="person"&gt;
        &lt;?php while ($people-&gt;have_posts()){ $people-&gt;the_post();
            global $post;
            $name = get_the_title();
            $slug = $post-&gt;post_name;
            $gender = get_post_meta($post-&gt;ID, 'gender', true);
        ?&gt;
        &lt;option data-gender="&lt;?php echo $gender; ?&gt;" value="&lt;?php echo $slug; ?&gt;"&gt;&lt;?php echo $name; ?&gt;&lt;/option&gt;
        &lt;?php } ?&gt;
    &lt;/select&gt;
&lt;?php }
</code></pre>


<p>I have a form, created as a plugin in wordpress. In the form is a drop down select menu that is populated with all entries from a custom post type called 'singers'.</p>

<p>i.e. "singer 1, singer 2, singer 3"</p>

<p>In this custom post type, each singer has meta box info, the info I'm interested in is 'singer_gender'. When a singer is selected, I want to pass a variable into a hidden field on that form with either "male" or "female"</p>

<p>So, for example, if Singer 1 is selected, and is male, my form would have the following hidden field:</p>

<pre><code>&lt;input type="hidden" name="singer_gender" id="singer_gender" value="&lt;?php echo singer_gender; ?&gt;" /&gt;
</code></pre>

<p>Is there a way to make this happen?</p>


Wordpress get metabox info for selected custom post type
