PHP 7.2 Warning

[good3n]

I get the PHP warning

Warning: count(): Parameter must be an array or an object that implements Countable in /path/to/wordpress/wp-includes/post-template.php on line 293

every time I programmatically create a post with wp_insert_post()

If I go back into the post via the admin UI and update it, the warning goes away.

I'm assuming because PHP 7.2 treats this as NULL.

If I edit the /wp-includes/post-template.php file it removes the warning.

Before (Warning):

<?php
if ( $page > count( $pages ) ) { // if the requested page doesn't exist
  $page = count( $pages ); // give them the highest numbered page that DOES exist
}

After (No Warning):

<?php
if(!empty($pages)) {
  if ( $page > count( $pages ) ) { // if the requested page doesn't exist
    $page = count( $pages ); // give them the highest numbered page that DOES exist
  }
}

@good3n Can you provide the code you are using to programmatically create a post?

Does this happen with a default theme and no plugins active on the site?

Sounds like a duplicate of #42814

I understand it's a duplicate but that ticket is closed.

Here is how I was able replicate the error Warning: count(): Parameter must be an array or an object that implements Countable in ... post-template.php on line 293 on the default TwentyNinenteen theme:

• Activated Easy Digital Downloads
• Created an actual post template - gist [here](​https://gist.github.com/wowthemesnet/7d7893b5af6d50049a3442709bb2e476).
• Assigned the template "My account" to a random page. Published.

The template was created following Pippin's [EDD guide](​https://docs.easydigitaldownloads.com/article/234-creating-a-customer-account-page)

PHP 7.2 , 7.3

Hi there, welcome to WordPress Trac! Thanks for the ticket.

• #42814 fixed this for get_the_excerpt().
• #47824 is a follow-up fix for get_the_content().

Closing as a duplicate of the above tickets.
