将上传的图像传递给facebook-> api函数的PHP SCRIPT问题 [英] PHP SCRIPT issue with passing the uploaded image to facebook->api function

问题描述

我有这个代码，它的工作很好，如果我提供一个图像的直接链接。

---

只是一个问题，我无法将我上传的图片传递给Facebook-> api（无论是否有效或者没有），并且以下总是回显

---

echo'只支持jpg，png和gif图像类型！'; / p>

---

我甚至删除了对图像类型的检查，并尝试从
$ img = realpath（$ _FILES [ PIC] [ tmp_name的值]）;
但$ img没有任何内容，并在Facebook上默认上传一个空的图像作为我的页面
请仔细检查我的以下代码，让我知道我的代码有什么问题，我该怎么办，而不是上传图像

'cookie'= > true，
'fileUpload'=> true，
））; 
 
 $ user = $ facebook-> getUser（）; 
 // echo $ user; 
 
 if（（$ facebook-> getUser（））== 0）
 {
 header（Location：{$ facebook-> getLoginUrl（array（'req_perms '=&''user_status，publish_stream，user_photos，offline_access，manage_pages'））}）; 
退出; 
} 
 else {
 $ accounts_list = $ facebook-> api（'/ me / accounts'）; 
 echo我连接; 
} 
 $ valid_files = array（'image / jpeg'，'image / png'，'image / gif'）; 
 
 
 //获取页面访问令牌作为页面发布
 foreach（$ accounts_list ['data'] as $ account）{
 if（$ account ['id'] == 194458563914948）{//我的页面id = 123456789 
 $ access_token = $ account ['access_token']; 
 echo< p>页面访问令牌：$ access_token< / p>; 
} 
} 
 
 //发布到页面墙
 
 if（isset（$ _ FILES）&&！empty（$ _ FILES） ）
 {
 if（！in_array（$ _ FILES ['pic'] ['type']，$ valid_files））
 {
 echo'只有jpg，png和gif图像类型被支持！ 
} 
 else {
＃上传照片
 $ img = realpath（$ _ FILES [pic] [tmp_name]）; 
 $ attachment = array（'message'=>'这是我的消息'，
'access_token'=> $ access_token，

 $ status = $ facebook-> api（'/ 194458563914948 / feed'，'POST'，$ attachment）; //我的页面id = 123456789 
 var_dump（$ status）;

解决方案

上传时，我收到以下回调

我是connectedarray（1）{[id] => string（31）
194458563914948_415487041812098}

I have this code and its working awsomely fine if i provide a direct link of an image.

---

Just and just only one problem i am not able to pass my uploaded image to facebook->api (whether its valid or not) and the following always echo

---

echo 'Only jpg, png and gif image types are supported!';

---

i even remove the check on image type and try to get the image from $img = realpath($_FILES["pic"]["tmp_name"]); but $img gets nothing in it and uploads a by default empty image on facebook as my page Kindly check my following code and let me know what is wrong with my code and what should i do instead to upload images

 <?


require 'src/facebook.php';

$app_id = "364900470214655";
$app_secret = "xxxxxxxx";

$facebook = new Facebook(array(
 'appId' => $app_id,
 'secret' => $app_secret,
 'cookie' => true,
 'fileUpload' => true,
));

$user = $facebook->getUser();
//echo $user;

if(($facebook->getUser())==0)
{
 header("Location:{$facebook->getLoginUrl(array('req_perms' => 'user_status,publish_stream,user_photos,offline_access,manage_pages'))}");
 exit;
}
else {
$accounts_list = $facebook->api('/me/accounts');
echo "i am connected";
}
  $valid_files = array('image/jpeg', 'image/png', 'image/gif');


//to get the page access token to post as a page
foreach($accounts_list['data'] as $account){
      if($account['id'] == 194458563914948){      // my page id =123456789
        $access_token = $account['access_token'];
        echo "<p>Page Access Token: $access_token</p>";
        }
    }

//posting to the page wall

if (isset($_FILES) && !empty($_FILES))
{  
if( !in_array($_FILES['pic']['type'], $valid_files ) )
{
  echo 'Only jpg, png and gif image types are supported!';
 }
 else{
  #Upload photo here
  $img = realpath($_FILES["pic"]["tmp_name"]);
$attachment = array('message' => 'this is my message',
                'access_token'  => $access_token,
                'name' => 'This is my demo Facebook application!',
                'caption' => "Caption of the Post",
                'link' => 'example.org',
                'description' => 'this is a description',
                'picture' => '@' . $img,
                'actions' => array(array('name' => 'Get Search',
                                  'link' => 'http://www.google.com'))
                );
$status = $facebook->api('/194458563914948/feed', 'POST', $attachment);   // my page id =123456789
var_dump($status);
}
}
?>
<body>
 <!-- Form for uploading the photo -->
 <div class="main">
  <p>Select a photo to upload on Facebook Fan Page</p>
  <form method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>" enctype="multipart/form-data">
  <p>Select the image: <input type="file" name="pic" /></p>
  <p><input class="post_but" type="submit" value="Upload to my album" /></p>
  </form>
 </div>
</body>

解决方案

Upon uploading, i received the following callback

i am connectedarray(1) { ["id"]=> string(31) "194458563914948_415487041812098" }

graph api explorer suggests the upload was successful
