添加谷歌分析事件以表格提交在PHP中

Question

我正在尋找添加事件以成功提交表單的PHP（購買的腳本）。我發現功能的PHP成功觸發，並標誌着我，我覺得分析去...

function emailSuccessfullySent() { 
global $translations, $lang, $options, $fdata, $is_ajax; 

// redirect to custom "success" page if it's been set 
if (!empty($options['redirect_url'])) { 
    if (!$is_ajax) { 
     header('Location: '.$options['redirect_url']); 
    } else { 
     echo json_encode(array('redirect' => array($options['redirect_url']))); 
    } 
    exit; 
} 

// if no redirect has been set, echo out the success message 
if ($is_ajax) { 
    echo json_encode(array('success' => array($translations->form->success->title->$lang))); 
    // analytics code here 
} else { 
    echo '<h2>'.$translations->form->success->title->$lang.'</h2>'; 
    // analytics code here 
} 

removeUploadsFromServer(); 
} 

...但我不知道如何觸發事件JS：

ga('send', 'event', 'Form Button', 'submit', 'Feedback');

您需要查看Google Analytics（分析）server-side measurement protocol。

這是一個PHP實現，我已經成功，但它可能是矯枉過正的用例（但至少它是一個參考）。 Here is the full code，但我已經簡化了這篇文章。

//Handle the parsing of the _ga cookie or setting it to a unique identifier 
function ga_parse_cookie(){ 
    if (isset($_COOKIE['_ga'])){ 
     list($version, $domainDepth, $cid1, $cid2) = explode('.', $_COOKIE["_ga"], 4); 
     $contents = array('version' => $version, 'domainDepth' => $domainDepth, 'cid' => $cid1 . '.' . $cid2); 
     $cid = $contents['cid']; 
    } else { 
     $cid = ga_generate_UUID(); 
    } 
    return $cid; 
} 

//Generate UUID v4 function (needed to generate a CID when one isn't available) 
function ga_generate_UUID(){ 
    return sprintf(
     '%04x%04x-%04x-%04x-%04x-%04x%04x%04x', 
     mt_rand(0, 0xffff), mt_rand(0, 0xffff), //32 bits for "time_low" 
     mt_rand(0, 0xffff), //16 bits for "time_mid" 
     mt_rand(0, 0x0fff) | 0x4000, //16 bits for "time_hi_and_version", Four most significant bits holds version number 4 
     mt_rand(0, 0x3fff) | 0x8000, //16 bits, 8 bits for "clk_seq_hi_res", 8 bits for "clk_seq_low", Two most significant bits holds zero and one for variant DCE1.1 
     mt_rand(0, 0xffff), mt_rand(0, 0xffff), mt_rand(0, 0xffff) //48 bits for "node" 
    ); 
} 

//Send Data to Google Analytics 
//https://developers.google.com/analytics/devguides/collection/protocol/v1/devguide#event 
function ga_send_data($data){ 
    $getString = 'https://ssl.google-analytics.com/collect'; 
    $getString .= '?payload_data&'; 
    $getString .= http_build_query($data); 
    $result = wp_remote_get($getString); 
    return $result; 
} 

//Send Event Function for Server-Side Google Analytics 
function ga_send_event($category=null, $action=null, $label=null, $value=null, $ni=1){ 
    //GA Parameter Guide: https://developers.google.com/analytics/devguides/collection/protocol/v1/parameters?hl=en 
    //GA Hit Builder: https://ga-dev-tools.appspot.com/hit-builder/ 
    $data = array(
     'v' => 1, 
     'tid' => 'UA-XXXXXX-Y', //***** Replace with your tracking ID! 
     'cid' => ga_parse_cookie(), 
     't' => 'event', 
     'ec' => $category, //Category (Required) 
     'ea' => $action, //Action (Required) 
     'el' => $label, //Label 
     'ev' => $value, //Value 
     'ni' => $ni, //Non-Interaction 
     'dh' => 'gearside.com', //Document Hostname 
     'dp' => '/', //Document path 
     'ua' => rawurlencode($_SERVER['HTTP_USER_AGENT']) //User Agent 
    ); 
    ga_send_data($data); 
} 

然後，在你評論的位置，你只需將功能：

ga_send_event('Form Button', 'Submit', 'Feedback');

另一種選擇是設置你的目標「成功」頁面上。

成功提交表單後，用戶將被重定向到成功頁面並觸發Google Analytics中的目標。
