Most of the WordPress users now use highly code themes that add to the functions and looks of their blogs. And for many such functions you need a add a custom field while publishing any post. Obviously many of us dont like to do this extra thing while blogging.
So here’s a solution to how to do it automatically.
Just goto your Dashboard > Appearance > Editor and look for ‘functions.php’ file.
The only thing you have to do is to edit the cutsom field name on line 6.
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);
}
}
Thats it, now a custom field will be added automatically every time you publish a post on your WordPress blog.
