You’re testing if assigning a value to $mylink was successful in the if statement rather than testing if it’s empty. Try something like: <?php $article_link = get_field(‘article_link’); if( $article_link[‘url’] ): ?> <a href=”https://wordpress.stackexchange.com/questions/246505/<?php echo $article_link[“url’]; ?>”><?php echo $article_link[‘title’]; ?></a> <?php endif; ?> See Example 1 in the ACF docs.
You just need to echo get_post_permalink() <?php echo get_post_permalink();?>
can you do this: get_post_meta(get_the_ID(), ”, true); print_r($meta); or get_post_meta(get_the_ID(), ‘my_custom_field’); print_r($meta); the first will pull all custom post type on the current post, and the second restricts to the field. You should get an array and then you’ll know which item in your array is the field title you’re looking to pull. then you … Read more
Variable scope – you need to globalise $wpdb before you can use it inside your function: function save_metaboxes() { global $wpdb; // Rest of your code }
First thing to check would be to make sure you have no spaces or invalid characters in your custom taxonomy names… This would cause them not to save properly. -shel
Depending on the ngg_images shortcode, you maybe need to echo the do_shortcode function. You can try function lilap_gid($atts, $content = “”){ $gid = get_post_meta(get_the_ID(), ‘gallery_id’, TRUE); ob_start(); echo do_shortcode( ‘[ngg_images tag_ids=”‘. $gid .'”]’); $content = ob_get_clean(); return $content; } add_shortcode( ‘gallery_display’, ‘lilap_gid’ );
I would recommend not using this in this way. I use ACF for pretty much everything outside of a basic content area. I’d recommend either using the tabs system or, probably more preferably, the Flexible Content add-on (it used to be an add-on, but is now part of ACF Pro). You can minimize/hide the flexible … Read more
It’s hard to tell what you’re working with from the image, but I’ll assume newline breaks. <?php $string = “http://www.podcast.com/track.mp3 2207703 audio/mpeg”; echo “<pre>”; echo $string; // should show multiple rows To grab the first line, try preg_match: // now grab the first line if( preg_match (‘/^(.*)$/m’, $string, $matches) ){ echo $matches[0]; // first line … Read more

Still, I found it is good to update some more details on the excellent post. Save your custom fields: add_action( ‘_wp_put_post_revision’, ‘save_cmb2’ ); function save_cmb2( $post, true ) { // save the custom field } Note that the second parameter is true if you like autosave. File: wp-includes/revision.php 275: /** 276: * Inserts post data … Read more
