I was trying to get results of a post meta relationship for a specific post id.

On a different language other than en_GB it seems to stop the function returning an array of results.

$meta_key = "your_key";
$meta_key = "your_post_id";
$sql = $wpdb->prepare(
"SELECT meta_value FROM {$wpdb->postmeta} WHERE meta_key = %s AND post_id = %s",
$meta_key,
$post_id
);
$related_ids = $wpdb->get_col($sql);

this strangely provides a different result than using get_post_meta.
I did not want to sync my custom fields as it creates a huge overhead.

I don’t know if this is a bug or by design.

I use the following code to add the contents of some custom checkout fields to my invoices and packing slips:

function custom_order_info_fields( $fields, $order ) {

	$custom_fields = array(
        array(
            'label' => 'Vergi Dairesi:',
	    'value' => get_post_meta( $order->get_id(), '_billing_vergidairesi', true ),
        ),
        array(
            'label' => 'T.C./Vergi No:',
			'value' => get_post_meta( $order->get_id(), '_billing_tckimlik_vergino', true ),
        ),
    );

    $fields = array_merge( $fields, $custom_fields );
    return $fields;
}

add_filter( 'wcdn_order_info_fields', 'custom_order_info_fields', 10, 2 );

The code works as intended except it gives empty values for the custom fields. There are no errors in debug logs, and when I dump some variables with:

var_dump(get_post_meta( $order->get_id(), '', false ));

I see the get_post_meta() returns data from my db table wp_postmeta instead of wp_wc_orders_meta where the custom fields are stored. wp_postmeta does have entries for every orderID that has a successful payment, because my payment gateway plugin stores them there, I’m not sure how or why.

Why does this happen and how do I make get_post_meta() return custom checkout fields?

Everything else seems to work fine. Below is my related config:

• WordPress 6.4.3
• WooCommerce 8.5.2
• Checkout Field Editor for WooCommerce 2.0.0
• Raft 1.1.1 (theme)
• Code Snippets 3.6.2
• Print Invoice & Delivery Notes for WooCommerce 4.8.1

I’m a newbie in wordpress, finding it difficult to retrieve author name from custom get post meta api

Below is snippet of my code

add_action( 'rest_api_init', 'my_register_template_hook' );
function my_register_template_hook() {
    register_rest_field( 'post', // any post type registered with API
        'appp',
        array(
            'get_callback'    => 'my_get_hook_data',
            'update_callback' => null,
            'schema'          => null,
        )
    );
}

function my_get_hook_data( $object, $field_name, $request ) {
    $data['post_detail']['below_title'] = '<span class="schedule-time">' . get_post_meta( $object['id'], 'author', true) . '</span>';

       $data['post_detail']['above_title'] = '<div class="post-featured-wrap">' . get_the_post_thumbnail( $object['id'], 'large', array( 'class' => 'post-featured' ) ) . '</div>'; 
       
   return $data;
}

I could only retrieve featured image

This isn’t outputting anything?

I have this line of code:
<?php echo ‘Course ID: ‘ . get_post_meta(17234, ‘_lesson_course’, true); ?>

I’ve stripped it out of a larger function, but I can’t even get this simple one to work. I’ve found the item in the database (screenshot: https://snag.gy/1IKwl4.jpg)

But it just returns back:
Course ID:

In other words, no value for the _lesson_course meta data.

I’ve double checked, there’s only one record, so it’s not an issue of pulling the wrong one. I’m stumped. Any ideas?

I’m using Divi, and added the following code below the post content:

<?php if(get_post_meta($post->ID, 'store-url', true) !== '') { ?>
	<div class="store"><a href="<?php echo get_post_meta($post->ID, 'store-url', true); ?>">Purchase a digital copy from $4 here. Up to 5184 x 3456 pixels in size</a>.</div>
<?php } ?>

I have a single custom field of name store-url with a value of a URL.

When I view a single post, I receive a white screen of death.

Help appreciated.

Steve

The if statement just checks if English or French is selected in qTranslate.

			<?php while ( have_posts() ) : the_post(); ?>
 
 			 <?php 	//This checks what language qTranslate has selected and returns the appropriate ShortDesc
					if (ppqtrans_getLanguage() =="en") {
					   $key = "byline_en";
					   $description = get_post_meta($post->ID, $key, true);
					}
					if (ppqtrans_getLanguage() =="fr") { 
					   $key = "byline_fr";
					   $description = get_post_meta($post->ID, $key, true);
					}
				?>
 
 
			
			<div class="product_thumbnail">
			<a href="<?php the_permalink() ?>">
			<?php //the_post_thumbnail grabs the post's "featured image" this feature has added theme support in the child theme functions.php ?>
			<?php the_post_thumbnail('thumbnail', array('class' => 'thumbnail')); ?>
			</a>
			
			<?php //This piece of code figures out the corrosponding post_title of the featured image ?>
			<h1 class="post_caption"><?php the_title(); ?></h1>
			<?php echo $description; ?>

			</div> <!-- product_thumbnail -->
