Question

I have 2 custom post types in WordPress: ‘homepage’ and ‘story’ and I have installed a plugin ‘Post from Site’. When I try to post into ‘story’ from front page with this plugin i get a few errors.

This is story.php 45:

if ( !current_user_can( 'edit_post', $post->ID )){
    return $post->ID;
}

and homepage.php 79:

add_action('save_post', 'save_details');
function save_details(){ 
global $post;   
update_post_meta($post->ID, "link_homepage", $_POST["link_homepage"]);  // homepage.php 79
}

Any help please?

Answer 1

The $post object isn’t available during the save_details function. When you call the function, pass in the $post_id as the first parameter. You’ll also want to move the authorization code in story.php into the save_details function.

function save_details($post_id){ 
    update_post_meta($post_id, "link_homepage", $_POST["link_homepage"]);  // homepage.php 79
}
