add current page url tag to content form 7

contact-form-7-curPage-tag.php

<?php
/*
* add this to your theme's functions.php file
*/
wpcf7_add_shortcode('sourceurl', 'wpcf7_sourceurl_shortcode_handler', true);
function wpcf7_sourceurl_shortcode_handler($tag) {
if (!is_array($tag)) return '';

$name = $tag['name'];
if (empty($name)) return '';

$html = '<input type="hidden" name="' . $name . '" value="http://' . $_SERVER["SERVER_NAME"].$_SERVER["REQUEST_URI"] . '" />';
return $html;
}

/*
* open your contact form and in the form part add:
"[sourceurl thesource]"
*
* and in the email part add:
"Source URL: <a href="[thesource]">[thesource]</a><br />"
*/

and you are done

Just a heads up, because of recent changes in wpcf7 to version 4.8, please update
is_array > is_object
and
wpcf7_add_shortcode > wpcf7_add_form_tag

Thanks

Also update on row #9:
$name = $tag->name;
instead of
$name = $tag['name'];

Thanks a lot

With @danstramer reviews this code works. Thanks
