Get Custom Field Value of a $post_id on wp_insert_post Action in functions.php

    I have this code in the functions.php file which emails the post content to the admin every time a pending post is added to the database:

    function send_email_on_pending_post_creation( $post_id ){
$post_title = get_the_title( $post_id );
$post_url = get_permalink( $post_id );
$post_content = get_post_field('post_content', $post_id);
$subject = 'New post pending!';

$message = "A new post is pending on the website:";
$message .= "<br><br>";
$message .= "<strong>Post Title: </strong>";
$message .= "<a href='" . $post_url . "'>" .$post_title. "</a>";
$message .= "<br><br>";
$message .= "<strong>Post Content:</strong><br>";
$message .= $post_content;
$message .= "<br><br>";

$attachments = get_post_meta( $post_id, 'attachment_url', true );

//$attachments = get_attachment_url($post_id);

$msg_headers = array('Content-Type: text/html; charset=UTF-8', 'From: "Website" < no-reply@website.com >');

//send email to admin
wp_mail( 'admin@website.com', $subject, $message, $msg_headers, $attachments );
}

add_action('wp_insert_post', 'send_email_on_pending_post_creation' );

    Could you please help me figure out how to get the value of any custom field inside the function that fires on the wp_insert_post action?

    I did a var_dump on $attachments but it returns empty. Do I need to hook something to any other action to be able to fetch the custom field value?

    Please help!

    Thanks!

    Are you sure your key is right? You can test it with: get_post_custom_keys

    $custom_field_keys = get_post_custom_keys($post_id);
foreach ( $custom_field_keys as $key => $value ) {
    $valuet = trim($value);
    if ( '_' == $valuet{0} )
        continue;
    $message .= $key . " => " . $value . "<br />";
}

    I think it’s having troubles getting post meta because it hasn’t been inserted fully yet.. You could try wp_insert_post_data hook and explore the second argument $postarr (in the demo link above), I haven’t looked/read, but it should hold your Custom Fields data (if not you could even explore using $_POST if it exists).

    (Also unless you’ve written your own get_attachment_url() it’s wp_get_attachment_url())
