rewrite script to use wp_remote_get instead of file_get_contents_curl

2 Views

I have a script that pulls the facebook likes via facebook graph and writes them in my DB. However it uses file_get_contents_curl for the request and this is causing problems, so I’d like to use the wp_remote_get() command. I’ve tried to change it but somehow I can’t do it (I don’t really have PHP knowledge).

Here’s the part of the script:

foreach($posts as $post)
    {

        $fb = json_decode(file_get_contents_curl('http://graph.facebook.com/?id='.get_permalink($post->ID)));
        if( !isset( $fb->likes) && isset($fb->shares) )
        {
            $fb->likes = $fb->shares;
        }
        //$fb->likes = isset($fb->likes) ? $fb->likes : 0;
        $myfblikes = sprintf("%04s", (int)$fb->likes);
        update_post_meta($post->ID, 'fb_likes', $myfblikes);
    }

  1. You can try this:

    foreach( $posts as $post )
{
    $url      = sprintf( 'http://graph.facebook.com/?id=%s', get_permalink( $post->ID ) );
    $response = wp_remote_get( $url,  array( 'timeout' => 15 ) );


    if( ! is_wp_error( $response ) 
        && isset( $response['response']['code'] )        
        && 200 === $response['response']['code'] )
    {
        $body = wp_remote_retrieve_body( $response );
        $fb   = json_decode( $body );

        if( ! isset( $fb->likes ) && isset( $fb->shares ) )
        {
            $fb->likes = $fb->shares;
        }

        if( isset( $fb->likes ) )
        {
            $myfblikes = sprintf( '%04s', (int) $fb->likes );
            update_post_meta( $post->ID, 'fb_likes', $myfblikes );
       }
    }
}

    where we can use wp_remote_retrieve_body() to get the response body of wp_remote_get().

  2. wp_remote_get returns an array, not a string. So,

    foreach($posts as $post) {

    // get remote document as JSON
    $json = wp_remote_get( 'http://graph.facebook.com/?id=' . get_permalink($post->ID) );

    // check for WP_Error
    if(is_wp_error($json))
        return false;

    // Decode JSON and get document body as associative array
    $fbData = json_decode($json['body'], true);

    // return (numeric) array value
    return intval($fbData['likes']);
}

    I’m not sure about get_permalink($post->ID) part. That’s OK only if you have a FB page for each post.

  3. This solved my problem, try out this

     $response = wp_remote_get( 'http://www.example.com/index.html' );
if( is_array($response) ) {
  $header = $response['headers']; // array of http header lines
  $body = $response['body']; // use the content
}
echo $body; // to print content

  4. Just change one function with the other. This requires also to change the way you are using json_decode() because wp_remote_get() returns an array and json_decode() requires a string.

    foreach($posts as $post) {

    $fb = wp_remote_get( 'http://graph.facebook.com/?id=' . get_permalink( $post->ID ) );

    if( ! is_wp_error( $fb ) ) {

        $body = json_decode( wp_remote_retrieve_body( $fb ) );

        if( ! isset( $body->likes) && isset( $body->shares ) ) {
            $body->likes = $body->shares;
        }

        $myfblikes = sprintf( "%04s", (int) $body->likes );
        update_post_meta( $post->ID, 'fb_likes', $myfblikes );
    }
}
