Wordpress remove thumbnail?

Question

WordPress

Tell me how to remove this thumbnail on the left? When adding news, I did not select a thumbnail, it is included in the template by default

Answer 1

It comes out only by editing the template. Otherwise, the template will fail.

Answer 2

You can do so.
Option 1 - in general, whatever they are, they will be deleted. You need to edit the functions.php file in your theme folder. P.s. be careful here, you can cheat the template by editing this file, make backups.

global $wpdb;

$attachments = $wpdb->get_results( "
     SELECT * 
     FROM $wpdb->postmeta 
     WHERE meta_key = '_thumbnail_id'
" );

foreach ( $attachments as $attachment ) {
    wp_delete_attachment( $attachment->meta_value, true );
}

$wpdb->query( "
    DELETE FROM $wpdb->postmeta 
    WHERE meta_key = '_thumbnail_id'
" );

Option 2:
Remove <?php the_post_thumbnail(); ?> in the single.php file Option
3 (never did this, always rules functions.php) - in the place where thumbnails are displayed, write the condition if ( has_post_thumbnail() and is_front_page() or is_category() )

Answer 3

try adding the following to functions.php

function my_post_image_html( $html, $post_id, $post_image_id ) {
  if(is_singular() ){
    $html = '';
  }
  return $html;
}
add_filter( 'post_thumbnail_html', 'my_post_image_html', 10, 3 );

this will disable the display of thumbnails on pages and individual posts

Answer 4

so in the settings of the post itself) as far as I remember, you can turn off the thumbnail))
