I am placing this code in custom_functions.php in my Thesis site. Here is URL to form:<br /> <a href="http://www.halloweenfun.net/submit-site-review/" rel="nofollow">http://www.halloweenfun.net/submit-site-review/</a></p> <p>Here is the code, but it is invalid, because it is "crashing" my custom_functions.php.<br /> Any help?</p> <pre><code>add_action(&quot;gform_pre_submission&quot;, &quot;create_attribution&quot;); function create_attribution($form){ if($form[&quot;id&quot;] == &#39;1&#39;){ $hidden-byline = &quot;Submitted by &quot; . $_POST[&quot;input_4&quot;] . &quot;, from &quot;. $_POST[&quot;input_5&quot;] . &quot;, who &quot; . $_POST[&quot;input_6&quot;] . &quot; affiliated with the site.&quot;; $_POST[&quot;input_8&quot;] = $hidden-byline; } return $form; }</code></pre>
