I'm trying to make this code work . i couldnt figure out why is not working

I'm trying to insert a custom field name 'views' to each (wordpress) post a random value !

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;
       $rand_num = rand(144, 544);
	if(!wp_is_post_revision($post_ID)) {
		add_post_meta($post_ID, 'views', '$rand_num', true);
	}
}

PHP:

 

Hey,

You wrapped the $rand_num variable in single quotes... You must wrap it in double quotes, in fact, quotes aren't even needed there to pass the value.

In other words... It should be:

add_post_meta($post_ID, 'views', $rand_num, true);

Thanks its working...

Is there any way i can change/update (a random num) the value for the custom field name 'views' for old post which is already published and has a custom field value already assign!

The above code works only for new post in wordpress!

 

Yea, just run a custom SQL command.

Don't use this, but just for the idea:

$rand_num = rand(144, 544);
mysql_query("UPDATE `{$posts_table}` SET `views`='{$rand_num}' WHERE `custom_field`>'';);

PHP:

 

i try the code below , but no luck , can u help me out

$rand_num = rand(144, 544);
mysql_query("update wp_postmeta set meta_value = '[B]{$rand_num}[/B]' WHERE meta_key = 'views';" )
