[英]Posting an Event to Page Wall with PHP
我已經將頭撞牆了兩周了,遍歷網絡,遍歷stackoverflow,反復測試並且未能將腳本發布到Fan Page上。 我終於得到了一個可以有效創建事件的腳本,但是它沒有出現在頁面上。
在DMCS將我指向PAGE訪問令牌之后,我擺弄着要生成它們。 現在,問題在於該事件出現在我的個人牆上,而不是我定位的頁面牆上。 誰能看到我所缺少的嗎?
這是最新編輯后的腳本:
<?php
$app_id = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxx";
$app_secret = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx";
$my_url = "http://xxxxxxxxxxxxxxxxxxxxxx.com/testfiles/fbeventform.php";
//Going to get the PAGE access code
//First to get USER Access Code
session_start();
$code = $_REQUEST["code"];
if(empty($code)) {
$_SESSION['state'] = md5(uniqid(rand(), TRUE)); //CSRF protection
$dialog_url = "https://www.facebook.com/dialog/oauth?client_id="
. $app_id . "&redirect_uri=" . urlencode($my_url) . "&state="
. $_SESSION['state'] . "&scope=create_event&scope=manage_pages";
echo("<script> top.location.href='" . $dialog_url . "'</script>");
}
if($_REQUEST['state'] == $_SESSION['state']) {
$token_url = "https://graph.facebook.com/oauth/access_token?"
. "client_id=" . $app_id . "&redirect_uri=" . urlencode($my_url)
. "&client_secret=" . $app_secret . "&code=" . $code;
$access_token = @file_get_contents($token_url);
$params = null;
parse_str($access_token, $params);
$graph_url = "https://graph.facebook.com/me?access_token="
. $params['access_token'];
$user = json_decode(file_get_contents($graph_url));
echo("Hello " . $user->name);
}
else {
echo("The state does not match. You may be a victim of CSRF.");
}
echo '<hr />' . $access_token;
//Now, getting the PAGE Access token, using the user access token
$page_token_url = "https://graph.facebook.com/" . $page_id . "?fields=access_token&" . $access_token;
$response = file_get_contents($page_token_url);
// Parse the return value and get the Page access token
$resp_obj = json_decode($response,true);
$page_access_token = $resp_obj['access_token'];
echo '<hr />' . $page_access_token;
//Post the event--here's the form function
if( !empty($_POST) && (empty($_POST['name']) || empty($_POST['start_time']) || empty($_POST['end_time'])) ) {
$msg = "Please check your inputs!";
} elseif(!empty($_POST)) {
$url = "https://graph.facebook.com/" . $page_id . "/events?" . $access_token;
$params = array();
// Prepare Event fields
foreach($_POST as $key=>$value)
if(strlen($value))
$params[$key] = $value;
// Check if we have an image
if( isset($_FILES) && !empty($_FILES['picture']['name']) ) {
$uploaddir = './upload/';
$uploadfile = $uploaddir . basename($_FILES['picture']['name']);
if (move_uploaded_file($_FILES['picture']['tmp_name'], $uploadfile)) {
$params['picture'] = "@" . realpath($uploadfile);
}
}
// Start the Graph API call
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $params);
$result = curl_exec($ch);
$decoded = json_decode($result, true);
curl_close($ch);
if(is_array($decoded) && isset($decoded['id'])) {
// Event created successfully, now we can
// a) save event id to DB AND/OR
// b) show success message AND/OR
// c) optionally, delete image from our server (if any)
$msg = "Event created successfully: {$decoded['id']}";
}
}
?>

這可以有效地創建事件,但它不會出現在我定位的頁面牆上。 我真的在這件事的盡頭...
感謝所有幫助,我將很樂意為最終用戶發布最終結果!
