title: How to convert values from select multiple into an email?
body: <p>How can I convert the selected <code>options</code> from a <code>select</code> multiple field into an email?</p>
  
  <pre><code>&lt;select name="fields[issues][]" multiple="multiple"&gt;
       &lt;xsl:for-each select="//issues-all/entry"&gt;
           &lt;option value="{@id}"&gt;
             &lt;xsl:value-of select="title"/&gt;
           &lt;/option&gt;
       &lt;/xsl:for-each&gt;
  &lt;/select&gt;
  </code></pre>
  
  <p>My standard approach doesn't work unfortunately:</p>
  
  <pre><code>&lt;input name="send-email[body]" value="fields[name,address,phone,issues]" type="hidden" /&gt;
  </code></pre>
  
  <p>The email gets delivered but contains the <code>value</code> as a string rather than the actual values.</p>
  
  <p>What am I missing here?</p>
  
  <p>Thanks for any help.</p>
