WP Canyon did wonderful tricks, this tricks is about how to automatically create a custom field when a post is published. This wonderful method is added some code on your functions.php files on your current theme.
Added Custom Field Automatically On Post - Abigail Clancy
The first time need to do is open your functions.php and paste Automatically Create a Custom Field code
add_action('publish_page', 'add_custom_field_automatically');
add_action('publish_post', 'add_custom_field_automatically');
function add_custom_field_automatically($post_ID) {
global $wpdb;
if(!wp_is_post_revision($post_ID)) {
add_post_meta($post_ID, 'field-name', 'custom value', true);
}
}
You’ll need to tweak this code to make it suitable on your cases, example you need to change field-name and the custom value of your custom field. Do you like Automatically Create a Custom Field tricks?
Good trick. I would like to do this only when the publish action is on a specfic custom post type. Can it be done?
For example, I have a custom post type called journal. When I hit publish, I want a custom field called ‘custom_post_template’ to be created with the value journalentry.php
Any thoughts? Thanks!!
Can you use this method to add multiple custom fields?
