如何在日曆中顯示我的Facebook朋友的照片

Question

我正在開發一個Facebook應用程序，我想在其中顯示我的朋友的照片以及他的出生日期。例如，今天是4月26日;如果我的任何朋友的生日的今天，他/她的照片應該在26日的日曆顯示時隙等

這裏是到目前爲止我的查詢：

$dt = "April 12"; 

$fql1 = "SELECT uid,pic_big,pic,pic_small,name 
    FROM user 
    WHERE birthday='".$dt."' AND 
     uid IN (SELECT uid2 FROM friend WHERE uid1= $user)"; 

我希望能夠同時處理完整日期（即1986年4月12日）和部分日期（4月12日）。

這是我的日曆代碼

<table width="100%" cellpadding="0" cellspacing="0" height="400" align="center" style="border:1px solid #cccccc;">

<?php 
    for($i = 1; $i < $numDays+1; $i++, $counter++){ 
     $dateToCompare = $month . '-' . $i . '-' . $year; 
     $timeStamp = strtotime("$year-$month-$i"); 
     //echo $timeStamp . '<br/>'; 
     if($i == 1){ 
      // Workout when the first day of the month is 
      $firstDay = date("w", $timeStamp); 
      for($j = 0; $j < $firstDay; $j++, $counter++){ 
       echo "<td>&nbsp;</td>"; 
      } 
     } 
     if($counter % 7 == 0){ 
      ?> 
      </tr><tr> 
      <?php 
     } 

     $pdate=strlen($i); 
     if($pdate==1) 
     { 
      $day="0".$i; 
     } 
     else 
     { 
      $day=$i; 
     } 

     $pmonth=strlen($month); 
     if($pmonth==1) 
     { 
      $mon="0".$month; 
     } 
     else 
     { 
      $mon=$month; 
     } 

    ?>

你的問題有點難以理解？;但根據我的理解 - 您在尋找朋友的特定日期的生日時遇到問題。

我會建議以不同的方式解決這個問題。看起來您正在爲日曆中的每個日期執行單個FQL查詢。我認爲加載所有用戶的朋友會更好，並循環瀏覽每個用戶的朋友並推斷日期。根據Facebook's documentation，生日日期格式是相對於用戶的語言環境而言的，因此您無法在該字段中可靠地進行查詢。

一種替代方案：（。編輯更加完整的，幾乎完全照搬現在pasteable）

<?php 

$facebook = new Facebook(array(
    'appId' => FB_APP_ID, //put your FB APP ID here 
    'secret' => FB_APP_SECRET, //put your FB APP SECRET KEY here 
    'cookie' => true 
)); 

$session = $facebook->getSession(); 

if ($session) 
{ 
    //check to see if we have friends_birthday permission 
    $perms = $facebook->api('/me/permissions'); 
} 

//we do this to see if the user is logged & installed 
if (empty($session) || empty($perms['friends_birthday'])) 
{ 
    //get url to oauth endpoint for install/login 
    $loginUrl = $facebook->getLoginUrl(array(
     //put the URL to this page, relative to the FB canvas 
     //(apps.facebook.com) here vvv 
     'next' => 'http://apps.facebook.com/path_to_your_app/index.php', 
     'req_perms' => 'friends_birthday' 
    )); 

    //use javascript to redirect. the oauth endpoint cant be loaded in an 
    //iframe, so we have to bust out of the iframe and load it in the browser 
    //and tell the oauth endpoint to come back to the fb canvas location 
    echo "<script>window.top.location='{$loginUrl}';</script>"; 
    exit; 
} 

$user = $session['uid']; //load the user id from the session array 

$cur_month_birthdays = array(); 
$cur_month = 4; //april 

try { 

    $fql1 = "SELECT uid, pic_big, pic,pic_small, name, birthday FROM user " 
    . "WHERE uid IN (" 
    .  "SELECT uid2 FROM friend WHERE uid1 = {$user} " 
    . ")"; 

    $friends = $facebook->api(array(
     'method' => 'fql.query', 
     'query'  => $fql1 
    )); 

    //make sure i have some friends... 
    if (!empty($friends)) 
    { 
     foreach ($friends as $friend) 
     { 
      //if this friend doesn't have their bday specified, skip them. 
      if (empty($friend['birthday'])) 
      { 
       continue; 
      } 

      //get unix time for the users' birthday 
      $birthday_ts = strtotime($friend['birthday']); 

      //if this friends birthday is this month... 
      if (date('m', $birthday_ts) == $cur_month) 
      { 
       //generate a month-day string for the birthdate 
       $birthday_str = date('m-d', $birthday_ts); 

       //initialize the array of friends with birthdays on this date 
       if (empty($cur_month_birthdays[ $birthday_str ])) 
       { 
        $cur_month_birthdays[ $birthday_str ] = array(); 
       } 

       $cur_month_birthdays[ $birthday_str ] []= $friend; 
      } 
     } 
    } 
} 
catch (Exception $e) 
{ 
    //error with facebook 
    error_log($e); 
} 

//output list of days in this month with friends that have birthdays 
print_r($cur_month_birthdays); 

上面的代碼將獲取所有用戶的通過每個朋友圈，並找到那些在你當前月份的生日（定義爲$cur_month）。然後，您可以循環並構建您的日曆，並且每天您都會檢查$cur_month_birthdays陣列，以查看是否有朋友在當天有生日，並適當地顯示它們。

希望有幫助！

** 編輯 **

這是我對上面的腳本輸出。我已經編輯了它的設置（包括FB PHP SDK的初始化和用戶會話的獲取），我假設你至少在代碼已經到位現在你可以看到結構數組的 - 你應該能夠很容易找出如何融入您的日曆
