Support » Fixing WordPress » Need help getting post meta data for url

  • I’m using the code below to retrieve images from Instagram that have a certain hashtag. The problem is I’m trying to make it so $tag_id is pulled from the custom field in the post.

    I know it has to do something with this:

    get_post_meta( $post->ID, 'tag_id', true);
    I just cant get it to work.

    function get_instagram($tag_id=marshmallow,$count=20,$width=100,$height=75 ){
        $url = ''.$tag_id.'/media/recent?client_id=10e03dd47cee4829a4aa8c93561a8ddb&access_token=37653788.10e03dd.d720972a6ef2422f974fb72127845370&count='.$count;
        // Cache the results as the instagram API is slow
        $cache = './'.sha1($url).'.json';
        if(file_exists($cache) && filemtime($cache) > time() - 60*60){
            // If a cache file exists, and it is newer than 1 hour, use it
            $jsonData = json_decode(file_get_contents($cache));
        } else {
            $jsonData = json_decode((file_get_contents($url)));
        $result = '<div id="instagram">'.PHP_EOL;
        foreach ($jsonData->data as $key=>$value) {
            $result .= "\t".'<a class="fancybox" data-fancybox-group="gallery"
                                title="'.htmlentities($value->caption->text).' '.htmlentities(date("F j, Y, g:i a", $value->caption->created_time)).'"
                                style="padding:3px" href="'.$value->images->standard_resolution->url.'">
                              <img src="'.$value->images->low_resolution->url.'" alt="'.$value->caption->text.'" width="'.$width.'" height="'.$height.'" />
        $result .= '</div>'.PHP_EOL;
        return $result;
    echo get_instagram();

  • In your function definition, the string marshmallow needs to be in quotes:

    function get_instagram($tag_id='marshmallow',$count=20,$width=100,$height=75 ){
