I have this site that uses the <!--nextpage--> tag in posts for pagination purposes. I want to disable pagination, but without deleting the tags for the database (maybe they'll want to use them again in the future).

Tried removing wp_link_pages(); from the template, but then it would only show the first page's content without the links - I don't know if that's how it should work or something wrong.

How can I make it that wordpress simply ignores <!--nextpage--> and display the full post at once?

You can try to use the the_post filter, to override the content pagination, that takes place within the setup_postdata() function ( PHP 5.4+ ):

/**
 * Ignore the <!--nextpage--> for content pagination.
 * 
 * @see http://wordpress.stackexchange.com/a/183587/26350
 */

add_action( 'the_post', function( $post )
{
    if ( false !== strpos( $post->post_content, '<!--nextpage-->' ) ) 
    {
        // Reset the global $pages:
        $GLOBALS['pages']     = [ $post->post_content ];

        // Reset the global $numpages:
        $GLOBALS['numpages']  = 0;

       // Reset the global $multipage:
        $GLOBALS['multipage'] = false;
    }

}, 99 );

to ignore the <!--nextpage--> feature.

The global $pages variable contains the paginated content:

$pages = explode('<!--nextpage-->', $content);

so that's why we need to restore it to:

$pages = array( $post->post_content );

We actually don't need to restore the $numpages variable, but we do it as part of the house cleaning. If we only restored $pages and $numpages=0 then we would get: 

<div class="page-links">Pages:</div>

The wp_link_pages() function checks if the global $multipage is true to display the content pagination output. So that's the variable to set to false to remove the whole output. We could also use the wp_link_pages filter to remove it.

  • Thanks, I was hopeing it would be simpler than adding hooks, but it did work like charm

  • Glad to hear it worked for you. Other approach would be to just remove it from the database (or just rename it) with a SQL query. But since you want to have the ability to turn it on again and handle new posts containing it, then I think the filtering solution is more suitable in this case. @LucianDavidescu

  • Here's another way to do this via the new content_pagination filter. @LucianDavidescu

Try to put <?php $GLOBALS['multipage'] = false; ?> in your loop. if doesn't show paginator in mobile: 

wp_is_mobile()
$GLOBALS['multipage'] = false;

I hope it is helpful for you
