Automatic Refresh all posts at once

4 Views

I created a function to save custom fields on publish a post. Something like this. 

function create_fields() {  
    global $post;     
    $casa_id = $post->ID;  
    update_post_meta($post->ID, 'casa_id', $casa_id);  
}  
add_action('publish_post', 'create_fields');

This function saves on a custom field some string.

Now the question:

How can i use this action on older posts? I have 1000 posts and i don’t want to refresh all the posts manually, is this possible?

  1. you can do something like this:

    $args = array(
    'posts_per_page' => 1000,
    'post_type' => 'post'
    );
$the_query = new WP_Query( $args );

if ( $the_query->have_posts() ) { 
    while ( $the_query->have_posts() ) {
        $the_query->the_post();
        $casa_id = $post->ID;
        update_post_meta($post->ID, 'casa_id', $casa_id);
    }
}

  2. It worked. I tryed this:

    function actualiza() {  
global $post;  
$args = array(  
    'numberposts' => -1,  
    'post_type' => 'post',  
    );  
$the_query = get_posts( $args );  
if ($the_query) {  
    foreach ($the_query as $post) {  
        $name = $post->post_title;
            update_post_meta($post->ID, 'name_post', $name);
    } 
}
}   
wp_reset_query();  
add_action('wp_head', 'actualiza');
