如何使用 Facebook 在我的应用程序中上传活动创建照片？

嗨
我想在我的应用程序（即事件创建）中上传一张活动照片，并且在我的数据库中，以下是我的代码：
HTML 文件：

<tr>
    <td class="style6 style1 style8"><span class="style30">Add Event Photo </span></td>
    <td colspan="4"><input name="userfile" type="file" class="style28" id="userfile"  size="50" height="25" /></td>
</tr>
<tr>
    <td><input name="image" type="image" src="img_2.gif" alt="submit form" border="0" /></td>
</tr>

现在是要上传的 php 代码：

if (isset($_POST['eventtitle'])&& $_FILES['userfile']['size'] > 0){
$fileName = $_FILES['userfile']['name'];
$tmpName  = $_FILES['userfile']['tmp_name'];
$fileSize = $_FILES['userfile']['size'];
$fileType = $_FILES['userfile']['type'];

$fp      = fopen($tmpName, 'r');
$content = fread($fp, filesize($tmpName));
$content = addslashes($content);
fclose($fp);

if(!get_magic_quotes_gpc())
{
    $fileName = addslashes($fileName);
}
mysql_query("INSERT INTO  event values('$uid','$eventID','$newDate','$newtime','$newDate2','$newtime1','$name','$location','$street','$city','$fileName', '$fileSize', '$fileType','$content','$description')");
mysql_close($con);
?>

name、size、type 和 content 是图像的字段。

Hi
I want to upload a event photo in my app ie event create and also in my database the following is my code:
HTML file:

<tr>
    <td class="style6 style1 style8"><span class="style30">Add Event Photo </span></td>
    <td colspan="4"><input name="userfile" type="file" class="style28" id="userfile"  size="50" height="25" /></td>
</tr>
<tr>
    <td><input name="image" type="image" src="img_2.gif" alt="submit form" border="0" /></td>
</tr>

now the php code to upload:

if (isset($_POST['eventtitle'])&& $_FILES['userfile']['size'] > 0){
$fileName = $_FILES['userfile']['name'];
$tmpName  = $_FILES['userfile']['tmp_name'];
$fileSize = $_FILES['userfile']['size'];
$fileType = $_FILES['userfile']['type'];

$fp      = fopen($tmpName, 'r');
$content = fread($fp, filesize($tmpName));
$content = addslashes($content);
fclose($fp);

if(!get_magic_quotes_gpc())
{
    $fileName = addslashes($fileName);
}
mysql_query("INSERT INTO  event values('$uid','$eventID','$newDate','$newtime','$newDate2','$newtime1','$name','$location','$street','$city','$fileName', '$fileSize', '$fileType','$content','$description')");
mysql_close($con);
?>

name, size, type and content are fields for the image.

好吧，我两天前写了一篇关于此的教程：如何：使用 Graph API 创建 Facebook 事件 – 高级

示例代码：

<?php
$app_id = "APP_ID";
$app_secret = "APP_SECRET";
$my_url = "REDIRECT_URL"; // mainly this should be the same URL to THIS page

$code = $_REQUEST["code"];

if(empty($code)) {
    $auth_url = "http://www.facebook.com/dialog/oauth?client_id="
    . $app_id . "&redirect_uri=" . urlencode($my_url)
    . "&scope=create_event";
    echo("<script>top.location.href='" . $auth_url . "'</script>");
}

$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);

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/me/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);
        }
    }
    $params['method'] = "post";

    // Start the Graph API call
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL,$url);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 2);
    curl_setopt($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']}";
    }
}
?>

Well, I've written a tutorial about this two days ago: How To: Create Facebook Events Using Graph API – Advanced

    echo("<script>top.location.href='" . $auth_url . "'</script>");
}

$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);

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/me/events?" . $access_token;
