Pulling posts from another WordPress site

Question

I am trying to get the 2 latest posts from my personal website, using the code below from http://codex.wordpress.org/Function_Reference/fetch_feed#Usage

<h2><?php _e( 'Recent news from Some-Other Blog:', 'my-text-domain' ); ?></h2>

<?php // Get RSS Feed(s)
include_once( ABSPATH . WPINC . '/feed.php' );

// Get a SimplePie feed object from the specified feed source.
$rss = fetch_feed( 'THISISWHEREMYURLGOES/' );

$maxitems = 0;

if ( ! is_wp_error( $rss ) ) : // Checks that the object is created correctly

    // Figure out how many total items there are, but limit it to 5. 
    $maxitems = $rss->get_item_quantity( 2 ); 

    // Build an array of all the items, starting with element 0 (first element).
    $rss_items = $rss->get_items( 0, $maxitems );

endif;
?>

<ul>
<?php if ( $maxitems == 0 ) : ?>
    <li><?php _e( 'No items', 'my-text-domain' ); ?></li>
<?php else : ?>
    <?php // Loop through each feed item and display each item as a hyperlink. ?>
    <?php foreach ( $rss_items as $item ) : ?>
        <?php echo esc_html( $item->get_title() );  ?>
        <li>
            <a href="<?php echo esc_url( $item->get_permalink() ); ?>"
                title="<?php printf( __( 'Posted %s', 'my-text-domain' ), $item->get_date('j F Y | g:i a') ); ?>">
                <?php echo esc_html( $item->get_title() ); ?>                    
                <?php printf( __( 'Posted %s', 'my-text-domain' ), $item->get_date('j F Y | g:i a') ); ?>

            </a>
        </li>
    <?php endforeach; ?>
<?php endif; ?>

With this code, I can get the Posts URL, the title and the date posted, which is great!

Now, trying to get the image is another issue. I am trying to use :

<?php echo esc_html( $item->the_post_thumbnail() ); ?> 

But I get the error : Fatal error: Call to undefined method SimplePie_Item::the_post_thumbnail()

So, using SimplePie, is there a way to get the posts image?

MAJOR EDIT:

This way of getting the RSS feed isn't great, it is causing alot of issues throughout the site, so if anyone could show me/direct me to something where I can get the 4 latest posts from another WordPress site, that'd be awesome!

Answer 1

As you've found, WordPress feeds have some limitations. Since you've asked for an alternative solution, I'd definitely recommend using WP REST API .

Since WP API isn't yet part of the WP Core, you'll want to do the following:

1. Head to your Plugins panel (on the site you're trying to pull posts from...your personal website) and install WP REST API (WP API) .
2. Activate the plugin
3. Getting your posts is as easy as going to: http://yoursite.com/wp-json/posts

Since you only want four posts, you can use filters:

http://yoursite.com/wp-json/posts?filter[posts_per_page]=4

To get this JSON into a usable state in PHP:

// Get the JSON
$json = file_get_contents('http://yoursite.com/wp-json/posts?filter[posts_per_page]=4');
// Convert the JSON to an array of posts
$posts = json_decode($json);

You can now digest this $posts array however you want (by looping through it). For example:

foreach ($posts as $p) {
    echo '<p>Title: ' . $p->title . '</p>';
    echo '<p>Date:  ' . date('F jS', strtotime($p->date)) . '</p>';
    // Output the featured image (if there is one)
    echo $p->featured_image ? '<img src="' . $p->featured_image->guid . '">' : '';
}

More info in the WP API docs .

Answer 2

If you dont want to use WP REST API , you can give a try to Wordpress Developers API .

You will have to authorize Wordpress Jetpack plugin for this. And then enable the REST API.

<?php
$posts = json_decode(file_get_contents("https://public-api.wordpress.com/rest/v1.1/sites/{yoursite.com}/posts"));
//You can use the $posts variable afterwards
?>
