Post thumbnails not showing in post lists for imported posts about customizr

[eri-trabiccolo]

I also ran an export/import but wasn't able to reproduce the issue :/

What do you think if we put a call to action button in the post list customize section to re-generate the thumb field (this button should have a description which doesn't make users think we re-generate the thumbnails ). The code could be something simple like the following (the LIMIT is to avoid memory issues - we'll actually avoid them this way? need to test this aspect):

function generate_tc_thumb_fld(){
  global $wpdb;
  $_has_posts = true;
  $_offset = 0;

  while ( $_has_posts ) {
    $_posts = $wpdb->get_results( "
      SELECT `ID` FROM $wpdb->posts 
      WHERE `post_status` = 'publish'  
      LIMIT 20 OFFSET " . $_offset
    );
    $_has_posts = count($_posts) > 0;
    if ( $_has_posts ) {
      $_offset = $_offset + count($_posts);
      if ( ! class_exists( 'TC_post_thumbnails' ) )
        TC___::$instance -> tc__( array('content' => array( array('inc/parts', 'post_thumbnails') ) ), true );
      foreach ( $_posts as $_post) 
        TC_post_thumbnails::$instance -> tc_set_thumb_info( $_post -> ID );
    }
  }
}

(maybe with an sql to remove the tc-thumb-fld occurrences before set them again)
But I'm assuming the issue is related to something which prevents the automatic refresh which your code already properly provides.

FYI the user having the issue solved it after this suggestion:

1. disable your plugins (maybe one of them might have conflicted)
2. browse the whole blog (post-lists) as admin

point 2 because we always refresh the thumb fld when user can upload images (right?).
I'm not sure if the user followed the 1) step too or if it was needed.

After all this is an edge case.
instead of adding a new button to the customizer, wouldn't it possible to hook at the end of the import process (there must a be a hook there) and run your code ?

A better version of it, yes, makes sense.
Anyway I tried to reproduce it but I couldn't reproduce it.
Hopefully will not be so much expensive.
