我正在尝试为Facebook页面创建一个自定义选项卡,它在页面选项卡中的firefox,chrome和Internet Explorer 8中完全适用于我,并且作为直接链接,但对于其他人来说,它只是没有'拿起他们的喜欢。
这是我的代码:
require 'src/facebook.php';
// Create our Application instance (replace this with your appId and secret).
$facebook = new Facebook(array(
'appId' => 'xxxxxxxx',
'secret' => 'xxxxxx',
));
$user = $facebook->getUser();
// alternative to the below but only works on the facebook tab itself
$signed_request = $_REQUEST["signed_request"];
list($encoded_sig, $payload) = explode('.', $signed_request, 2);
$data = json_decode(base64_decode(strtr($payload, '-_', '+/')), true);
if (empty($data["page"]["liked"])) {
echo "You are not a fan!";
} else {
echo "Welcome back fan!";
}
if ($user) {
try {
$likes = $facebook->api("/me/likes/xxxxxxxxxx");
if( !empty($likes['data']) )
{
?>
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>
<script type="text/javascript">
$(document).ready(function() {
$('#fan').click(function() {
$('#fan').animate({
opacity: 0.2,
width: 'auto',
height: 'auto'
}, 1000, function() {
// Animation complete.
$('#fan').hide('slow');
$('#voucher').show('slow');
});
});
});
</script>
<a href="#"><img id="fan" src="//www.website.com/facebook/2011/voucher/fans_image.jpg" alt="10% off" style="border:0;" /></a>
<div style="display:none; position:absolute; top:0; left:0;" id="voucher" >
<a href="//www.website.com/facebook/2011/voucher/EYE-TEST-DECEMBER-11.pdf" target="_blank"><img src="//www.website.com/facebook/2011/voucher/fb-voucher-dec11.jpg" style="border:0;" alt="10% off" /></a> <br />
<p style="text-align:center"><a href="//www.website.com/facebook/2011/voucher/EYE-TEST-DECEMBER-11.pdf" target="_blank">Click here to download PDF version of the voucher.</a></p>
</div>
<?php
}
else
{
?>
<img style="position:absolute; top:0; left:0; border:0;" id="all" src="//www.website.com/facebook/2011/voucher/fb_like_page.jpg" width="520" height="304" alt="Click LIKE button to get 10% off." />
<?php
}
} catch (FacebookApiException $e) {
error_log($e);
$user = null;
}
}
if ($user) {
$logoutUrl = $facebook->getLogoutUrl();
}
else {
//user isn't logged in so just show un-liked image
?>
<img style="position:absolute; top:0; left:0; border:0;" id="all" src="//www.website.com/facebook/2011/voucher/fb_like_page.jpg" width="520" height="304" alt="Click LIKE button to get 10% off." />
<?php
$loginUrl = $facebook->getLoginUrl(array(
'scope' => 'user_likes'
));
}
更多信息 该应用程序在沙箱模式下不。
我在想,因为该应用程序出现在我的帐户设置中,这就是为什么它只适用于我,但如果我查看其他粉丝选项标签,他们就不会弹出权限通知,以便可以&是不是这样?
答案 0 :(得分:1)
持久性通知适用于明确授权应用的用户,这是您似乎已完成的操作。您向拥有和未授权申请的人显示信息,而不是向喜欢或不喜欢您网页的人显示
// alternative to the below but only works on the facebook tab itself
$signed_request = $_REQUEST["signed_request"];
list($encoded_sig, $payload) = explode('.', $signed_request, 2);
$data = json_decode(base64_decode(strtr($payload, '-_', '+/')), true);
if (empty($data["page"]["liked"])) {
echo "You are not a fan!";
} else {
echo "Welcome back fan!";
}
这里的代码是我希望喜欢或不喜欢页面选项卡的人。这与授权位于该选项卡上的应用程序无关。当用户喜欢您的页面时,您无法访问其用户ID等,只有他们喜欢该页面。但是您的代码似乎正在使用api来测试用户是否喜欢该页面。我的猜测是你的用户对象实际上是null,因为用户没有明确授权该页面选项卡上的应用程序。这有意义吗?
因此,除非他们已授予对该应用的访问权限:
if ($user) {
$logoutUrl = $facebook->getLogoutUrl();
}
else {
//user isn't logged in so just show un-liked image
?>
<img style="position:absolute; top:0; left:0; border:0;" id="all" src="//www.website.com/facebook/2011/voucher/fb_like_page.jpg" width="520" height="304" alt="Click LIKE button to get 10% off." />
<?php
$loginUrl = $facebook->getLoginUrl(array(
'scope' => 'user_likes'
));
}
$ user将在此处为空,您将告诉人们喜欢您的网页是否已经这样做
