我正在使用facebook提供的graph-api。版本号为3.1.0。我的代码工作得很好，但它显示了用户的所有图像，而不管相册。
我想更改我的代码，以便用户只能看到他/她所选择的相册的图像。
我的意思是图像应该在相册中显示。
我的代码如下:
index . php

更新:
在关闭标记之前，我在代码中添加了一个函数。该函数如下:
<script type="text/javascript">
function showAlbum(albumId){
alert('Album Id'+albumId);
var fbhtml = '';
<?php
$albmId = albumId;
// get all photos for album
$i=0;
$photos = $facebook->api("/".$albmId."/photos");
foreach($photos['data'] as $photo){ ?>
fbhtml += '<div class="baby_img">';
fbhtml += '<input type="checkbox" id="facebook_<?php echo $i; ?>" name="facebook[]" value="<?php echo $photo["source"]; ?>" class="styled" />';
fbhtml += '<img src="<?php echo $photo["source"]; ?>" class="img-responsive" style="width:100px !important; height:100px !important;" />';
fbhtml += '</div>';
<?php
$i++;
$showBtn=true;
}
?>
$('#fbhtmlImage').html(fbhtml);
}
</script>
函数正在工作，但我没有得到所需的输出。它正在获取我相册中没有的图像。没有得到相册里的图片
使用ajax解决
function showAlbum(albumId){
var fbhtml = '';
$.ajax({
type: "GET",
url: "fbphotos.php",
data: { albumId: albumId }
}).done(function(response) {
var response = jQuery.parseJSON(response );
if(response['data'].length>0)
{
for(var x=0; x<response['data'].length; x++){
fbhtml += '<div class="baby_img">';
fbhtml += '<input type="checkbox" id="facebook_'+x+'" name="facebook[]" value="'+response['data'][x]['source']+'" class="styled" />';
fbhtml += '<img src="'+response['data'][x]['source']+'" class="img-responsive" style="width:100px !important; height:100px !important;" />';
fbhtml += '</div>';
}
}
else
{
fbhtml = 'There are no image(s) in this album.';
}
$('#fbhtmlImage').html(fbhtml);
$('#fbmodal-footer').show();
$(".loader").fadeOut("slow");
});
}
这可能是对你的回答，但它更多的是我的评论，但它很长，这就是为什么我在这里发布
在这部分代码中你已经有了你想要的东西。第一个循环迭代所有的相册，因此您可以使用album.name来显示相册，然后您可以传递id(无论您想要什么，就像点击链接一样)来显示相应的照片。
查看我对你代码的注释:
<?php
$albums = $facebook->api("/me/albums"); //This fetches all the albums
foreach($albums['data'] as $album){ //This loops every available album
//Here you can get the name of the album
//by $album['name']
//and id by $album['id']
//You can have links here
echo '<a href="#" onclick="showAlbum('.$album['id'].')">'.$album['name'].'</a>';
}
?>
<script>
function showAlbum(albumId){
// get all photos for album
//use Js SDK here not the php SDK to load the images
//If you want to still use the php sdk then make an ajax call
//to the file which can return images of specific album by id
}
</script>
