reuse content on different domains

Alejandro · Aug 4th 2019

Hi there, I just wondering if can I reuse content (e.g. news articles) from a mainsite.com to site_A.com, site_B.com and site_C.com, of course, all of them using Perch; my idea is to publish news on mainsite.com and automatically publish on the other sites; is it possible to do this? I've tried to to do this using an RSS feed but I can't set up an image for each article and even worst, I can't set up a css style for the xml. Thanks

There's a few different approaches you could take. Are the sites all on the same hosting? Can they all connect to one database?

Alejandro · Aug 5th 2019

Hi Drewm, no really, they are on the same reseller account but separate account each. No, they are on different database.

Thanks.

In which case an RSS or JSON feed would be a good option between the sites.

Alejandro · Aug 6th 2019

Thanks Drew

Any suggestions on how to implement this using JSON? I did not find information in Perch Docs and Forum.

Are you using Perch or Runway?

Alejandro · Aug 7th 2019

Hi Drew,I'm using Perch, at the moment, but I can move to Runway if necessary, no problem.

There's probably three parts to this:

1. Produce the JSON feeds on your primary site

2. Write code (probably an app) to parse and use the JSON on the secondary sites

3. Figure out how/when those feeds should be refreshed (possibly a scheduled task)

For an experienced PHP developer this should be very straightforward, so it'll depend on your level of experience.

Hi Drew.

Thank you for your answer. I'm not an experienced PHP developer, so, I've been traying to do this using a XML feed.

My code for rss_post.html

Code

<item>
<title><perch:blog id="postTitle" /></title>
<link><perch:blog id="domain" /><perch:blog id="postURL" /></link>
<guid><perch:blog id="domain" /><perch:blog id="postURL" /></guid>
<description><![CDATA[<perch:blog id="excerpt" encode="false" />]]></description>
<pubDate><perch:blog id="postDateTime" format="D, d M Y H:i:s O" /></pubDate>
<enclosure url="https://mysite.com<perch:blog id="image" type="image" crop />" length="123456789" type="image/jpeg" />
</item>

My feed rss.php on my news folder

PHP

<?php include('../perch/runtime.php');?>
<?php
$domain = 'https://'.$_SERVER['HTTP_HOST'];
PerchSystem::set_var('domain', $domain);
header('Content-Type: application/rss+xml');
echo '<'.'?xml version="1.0"?'.'>';
?>
<rss version="2.0" xmlns:atom="http://www.w3.org/2005/Atom">
<channel>
<title>News</title>
<link><?php echo PerchUtil::html($domain); ?>/news/</link>
<description>News</description>
<atom:link href="<?php echo PerchUtil::html($domain); ?>/news/rss.php" rel="self" type="application/rss+xml" />
<?php
perch_blog_custom(array(
'template'=>'blog/rss_post.html',
'count'=>6,
'sort'=>'postDateTime',
'sort-order'=>'DESC',
));
?>
</channel>
</rss>

My problem is that I can't see post image on <item>. I've used

Code

length="123456789"

on <enclosure> because I don't know how can I obtain this value.

Thanks for your help.

drewm · Aug 11th 2019

I’m not quite sure what you’re asking. Is the image path not being output into the template? If not, what do you get, and what does that field look like in your post.html template? Do the attributes match?

Alejandro · Aug 12th 2019

Hi Drew, Thank you for your answer. My issue is: I can't see the blog image ("image") on my page to show rss feed. Path to the image is ok.

post.html

Code

<header class="cs-post-single-title">
<div class="cs-post-category-solid cs-clearfix">

Sorry, I don't understand what you mean by this.

Alejandro · Aug 12th 2019

Maybe, if you can take a look at my test page https://patagonia.uach.cl/index_rss_externo.php section "Noticias" (scroll down in the middle), I hope to see an image but it does not appear, <div></div> is empty.

Thanks

drewm · Aug 12th 2019

Where is the code for this page? This is different than the templates you've shown us.

Alejandro · Aug 12th 2019

Yes, I'm trying other way, here you go

PHP

<div class="container">
<?php
$xml_feed = new DOMDocument();
$xml_feed->load('https://patagonia.uach.cl/noticias/rss.php');
$feed_items = array();
foreach ($xml_feed->getElementsByTagName('item') as $node) {
$item = array (
'title' => $node->getElementsByTagName('title')->item(0)->nodeValue,
'desc' => $node->getElementsByTagName('description')->item(0)->nodeValue,
'link' => $node->getElementsByTagName('link')->item(0)->nodeValue,
'pubDate' => $node->getElementsByTagName('pubDate')->item(0)->nodeValue,
'image' => $node->getElementsByTagName('image')->item(0)->nodeValue,
);
array_push($feed_items, $item);
}
foreach ($feed_items as $feed_item) { ?>
<table style="margin-left: 20px;" border="0" cellpadding="0" cellspacing="0" width="360">
<tbody>
<tr>
<td height="140" width="230">
<span><?php echo $feed_item["pubDate"] ?></span>
<h2><?php echo $feed_item["title"] ?></h2>
<a class="ver_mas" href="<?php echo $feed_item["link"] ?>">ver más</a>
</td>
<td align="right" width="130">
<div><?php echo $feed_item["image"] ?></div>
</td>
</tr>
</tbody>
</table>
<?php } ?>
</div>

$node->getElementsByTagName('image')

Your tag is called img not image.

Alejandro · Aug 12th 2019

Ok, I did a change but still not working

PHP

<?php
$xml_feed = new DOMDocument();
$xml_feed->load('https://patagonia.uach.cl/noticias/rss.php');
$feed_items = array();
foreach ($xml_feed->getElementsByTagName('item') as $node) {
$item = array (
'title' => $node->getElementsByTagName('title')->item(0)->nodeValue,
'desc' => $node->getElementsByTagName('description')->item(0)->nodeValue,
'link' => $node->getElementsByTagName('link')->item(0)->nodeValue,
'pubDate' => $node->getElementsByTagName('pubDate')->item(0)->nodeValue,
'img' => $node->getElementsByTagName('img')->item(0)->nodeValue,
);
array_push($feed_items, $item);
}
foreach ($feed_items as $feed_item) { ?>
<table style="margin-left: 20px;" border="0" cellpadding="0" cellspacing="0" width="360">
<tbody>
<tr>
<td height="140" width="230">
<span><?php echo $feed_item["pubDate"] ?></span>

Here's my updated rss_post.html template:

Code

<item>
<title><perch:blog id="postTitle" /></title>
<link><perch:blog id="postURL" /></link>
<guid><perch:blog id="domain" /><perch:blog id="postURL" /></guid>
<description><![CDATA[<perch:blog id="excerpt" encode="false" />]]></description>
<pubDate><perch:blog id="postDateTime" format="D, d M Y H:i:s O" /></pubDate>
<img src="https://patagonia.uach.cl<perch:blog id="image" type="image" width="100" height="75" crop="true"/>" />
</item>

'img' => $node->getElementsByTagName('img')->item(0)->nodeValue,

Your tag has no nodeValue as it's an empty tag. You'll want to get the value of the src attribute here instead.
