Is there a has_more_tag() method or equivalent?

1. Quite simply put: there is no built in function that does the same thing as your code above.

2. Making a quick note of the codes we could use to show the_content(); if the More tag exists, and the_excerpt(); if it doesn’t.

   Code #1 (Recommended)

   <?php
       if( strpos( $post->post_content, '<!--more-->' ) ) {
           the_content();
       }
       else {
           the_excerpt();
       }
   ?>

   Code #2

   <?php
       if( strpos( get_the_content(), 'more-link' ) === false ) {
           the_excerpt();
       }
       else {
           the_content();
       }
   ?>
   

   (Credit: Michael) Basically does #1 the other way around.

   Code #3

   <?php
       if( preg_match( '/<!--more(.*?)?-->/', $post->post_content ) ) {
           the_content();
       }
       else {
           the_excerpt();
       }
   ?>
   

   (Credit: helgatheviking) For use only in edge cases where you cannot use strpos(). Generally strpos() is more efficient than preg_match().

   Making it more conditional:

   <?php
       if ( is_home() || is_archive() || is_search() ) {
           if( strpos( $post->post_content, '<!--more-->' ) ) {
               the_content( __( 'Continue reading <span class="meta-nav">&rarr;</span>', 'twentytwelve' ) );
           }
           else {
               the_excerpt();
           }
       }
       else {
           the_content();
       }
   ?>
   

   What does it do? If the page shown is home, archive or search results page, then show the_content(); if the More tag exists, the_excerpt(); if it doesn’t, and simply show the_excerpt(); on all other pages.

3. I could not get any of the provided solution to work, however I found this to be working well for me, publishing it as an extra solution if anybody else had problems getting it working. Just testing if the content is them same with and without stripping the teaser.

           // Choose the manual excerpt if exists
           if ( has_excerpt() ) :
                   the_excerpt();
   
           // Is there a more tag? Then use the teaser. ()
           elseif ( get_the_content('', false) != get_the_content('', true)  ) :
               global $more; 
               $more = 0;
               echo strip_tags(get_the_content( '', false ));
               $more = 1;
   
           // Otherwise make an automatic excerpt
           else :
               the_excerpt(40);
   
           endif;

4. For the ones searching for a more WP related answer, You can use this logic:

   $info = get_extended($post->post_content);
   if(!empty($info["extended"])){
      // it has a read more tag.
   }else{
      // it hasn't one.
   }
   

   For this, you can blame the WP Core if it doesn’t work right. 🙂
