On WPCF7 I have a function that when someone lands on the website with this parameter on the URL "myweb.com/?promo=mypromo", the it saves the "mypromo" as cookie for a 6 months period and if anyone contacts me, the "mypromo" comes attached.</p> <p>Question is, how to do this with GF. I am using GF integration with salesforce, all working smoothly btw, just this promocode thing not at all. I just don't know how to set a new variable in GF fields with the dynamic promocode call I need.</p> <p>This is the function I am using with WPCF7:</p> <p>&lt;?php<br /> function tracking_cookie(){<br /> if (!isset($_COOKIE['RD7cViG1mO6y'])) {<br /> setcookie('RD7cViG1mO6y',base64_encode($_GET['promo']), strtotime('+6 month'), '/', 'myweb.com'); //Tracks Promo code<br /> if (!isset($_COOKIE['qsJKX2zx3Le1'])) {<br /> setcookie('qsJKX2zx3Le1',base64_encode($_SERVER['HTTP_REFERER']),strtotime('+6 month'), '/', 'myweb.com');<br /> } //Tracks First Referrer to the website<br /> }<br /> }<br /> add_action('init','tracking_cookie',0);<br /> wpcf7_add_shortcode( 'tracker', 'wpcf7_tracker_shortcode', true );</p> <p>function wpcf7_tracker_shortcode( $tag ) {<br /> global $wpcf7_contact_form;<br /> if ( ! is_array( $tag ) )<br /> return '';<br /> $name = $tag['name'];<br /> if (!isset($_COOKIE['RD7cViG1mO6y'])) {<br /> $tracker_code=$_GET['promo'];<br /> } else {<br /> $tracker_code=base64_decode($_COOKIE['RD7cViG1mO6y']);<br /> }<br /> $html = $html.'&lt;input type="hidden" name="'.$name.'" value="'.$tracker_code.'" /&gt;';<br /> return $html;<br /> }</p> <p>wpcf7_add_shortcode( 'referrer', 'wpcf7_referrer_shortcode', true );<br /> function wpcf7_referrer_shortcode( $tag ) {<br /> global $wpcf7_contact_form;<br /> if ( ! is_array( $tag ) )<br /> return '';<br /> $name = $tag['name'];<br /> if (!isset($_COOKIE['qsJKX2zx3Le1'])) {<br /> $referrer=$_SERVER['HTTP_REFERER'];<br /> } else {<br /> $referrer=base64_decode($_COOKIE['qsJKX2zx3Le1']);<br /> }<br /> $html = $html.'&lt;input type="hidden" name="'.$name.'" value="'.$referrer.'" /&gt;';<br /> return $html;<br /> }</p> <p>?&gt;</p> <p>than I set [promo_code] and [referrer_link] in WPCF7 mail and this is how I have been using.</p> <p>Can someone help me making this work on a GF hidden promocode field? (btw my salesforce promocode parameter is "Promo_Code__c").</p> <p>Appreciate.<br /> Hugo </p>
