Facebook的PHP API

Question

我运行这个简单的代码：

<?php 
$keyword = 'iPhone'; 
$graph_url = "https://graph.facebook.com/search?"; 
$graph_url .= "&type=post"; 
$graph_url .= "&q=$keyword"; 
$results = file_get_contents($graph_url); 

$json = json_decode($results); 

foreach($json->data as $show) { 
echo '<img src="'.$show->picture.'" alt="some_text"/><br />'; 
echo $show->from->name . "<br />"; 
echo $show->message . "<br />"; 
echo $show->created_time . "<br />"; 
echo "<hr>"; 
} 
?> 

据检索关键字“iPhone”的所有Facebook的帖子是怎么来的一些内容是空的，而Facebook的个人资料图片不显示在所有职位，我将如何限制职位。我如何去解决这个问题，任何人都指向正确的方向？

Answer 1

<?php 
$keyword = 'iPhone'; 
$graph_url = "https://graph.facebook.com/search?"; 
$graph_url .= "&type=post"; 
$graph_url .= "&q=$keyword"; 

//添加这些行

$graph_url .= "&fields=from,caption,created_time,picture"; 
$graph_url .= "&limit=$number"; 

//

$结果=的file_get_contents（$ graph_url）;

$json = json_decode($results); 

foreach($json->data as $show) { 
echo '<img src="'.$show->picture.'" alt="some_text"/><br />'; 
echo $show->from->name . "<br />"; 
echo $show->caption. "<br />"; 
echo $show->created_time . "<br />"; 
echo "<hr>"; 
} 
?>
