我制作了一个模块,可以显示instagram个人资料中的最新图像,它在Joomla 3.4.8中使用一个小的弹出库非常完美我想添加个人资料图像profile_picture,但它当然应该只出现一次。我尝试过各种php echo,但没有运气
有人能帮忙吗?
PHP
<?php
// Supply a user id and an access token
$userid = $params->get('klintweb_insta_id');
$accessToken = $params->get('klintweb_insta_access_token');
$count = $params->get('klintweb_insta_count');
// Gets post and image
function fetchData($url){
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_TIMEOUT, 20);
$result = curl_exec($ch);
curl_close($ch);
return $result;
}
// Pulls and parses data.
$result = fetchData("https://api.instagram.com/v1/users/{$userid}/media/recent/?count={$count}&access_token={$accessToken}");
$result = json_decode($result);
?>
前臂
<?php foreach ($result->data as $post): ?>
{emailcloak=off}
<!-- Renders images. @Options (thumbnail,low_resoulution, high_resolution) -->
<span class="KlintWebInstaSpan">
<a data-mediabox-group="insta" type="image/jpeg" class="jcepopup noicon" data-mediabox-caption="<?= rtrim(strip_tags(substr ($post->caption->text,0,140))).'...'; ?>" data-mediabox-title="rasmusjorgensen128" href="<?= $post->images->standard_resolution->url ?>">
<img src="<?= $post->images->thumbnail->url ?>" alt="Billede fra instagram" />
<span class="overlay"></span>
</a>
</span>
<?php endforeach ?>

感谢Adam Taylor你指出可以做得多么简单
也感谢Danoweb帮助
我理解得对吗?你正在循环浏览照片列表,并且还想访问个人资料图片并打印一次?
你需要循环浏览所有的照片吗?如果没有,您可以在打印照片后添加一个break
,以退出循环。
如果你也需要循环浏览照片,为什么不访问JSON中的第一个元素,从那里获取个人资料图片,然后循环浏览其余的照片?
编辑:就您的解决方案而言,直接访问第一张照片,打印相关的用户缩略图,然后继续循环并打印所有照片可能会更容易。类似于:
<div class="user">
<?php $post = $result->data[0]; ?>
<img src="<?= $post->user->profile_picture ?>" alt="<?= $post->user->username ?>" />
<span class="username"><?= $post->user->username ?></span>
</div>
<!-- do the rest of your looping/displaying photos -->
在您的解决方案中,您将数组切片为一个元素,然后当您真正想做的只是访问第一个元素时,在数组上循环。
据我所知,配置文件图片似乎在JSON响应中提供了两次。我会使用一个变量来跟踪我是否已经显示了个人资料图片,如果是,就不要显示第二个。例如:
<?php
$shown_profile = false;
foreach ($result->data as $post)
{
//WE HAVE NOT SHOWN PROFILE PIC, SHOW IT AND SET FLAG.
if($shown_profile == false and (image is profile pic) )
{
$shown_profile = true;
}
//WE HAVE ALREADY SHOWN PROFILE PIC AND THIS IMAGE IS A DUPLICATE
if($shown_profile == true and (image is profile pic) )
{
//JUMP TO THE NEXT LOOP INTERATION
continue;
}
//[THE REST OF YOUR FOREACH CODE]
}
?>
