My Gallery Photos are showing in the post's excerpts

Question

I just can't win with this project! All of a sudden, each post's gallery photos are showing up in the excerpt/preview of the post. Each post has a gallery of images that should only be visible on the actual post's page. Can anyone see what might be causing this?

Here is my code:

if ( has_post_thumbnail() ) {
     the_post_thumbnail();
}
else {
     get_the_image( array('size' => 'thumbnail',
                          'image_class' => 'wp-post-image'));   
}

Then in my functions file:

// This theme displays custom size (page-single) featured image on the Post's  page

function InsertFeaturedImage($content) {

    global $post;

    $original_content = $content;

    if ( current_theme_supports( 'post-thumbnails' ) ) {

        if ((is_page()) || (is_single())) {

            $content = get_the_image( array( 'size' => 'full' ) );
            $content .= $original_content;
        }
    }
    return $content;
}

add_filter( 'the_content', 'InsertFeaturedImage' );

You can view the site in question here: http://dependablecarcompany.com

You'll see the horribly broken site in question. There should only be the ONE excerpt representative thumbnail there, and not all the thumbs from the gallery too.

Thank You!

Answer 1

   if(  ( is_page() || is_single() ) && ( !is_home() &&  !is_front_page() )  ){
        $content = strip_shortcodes( $original_content); 
    }

if its home or front page don't show gallery

    if( is_home() || is_front_page() ) {
          // don't show gallery
          $content = strip_shortcodes( $original_content); 
    } else {
          $content = get_the_image( array( 'size' => 'full' ) );
          $content .= $original_content;
    }

The post was using shorttags to print the gallery, get_the_image() printed the thumbnail.

so by removing the shorttags from appearing in the front page, the gallery no longer is shown on it, but will show on other pages, and also, categories, tags etc.

To further improve on that, add || is_archive() to the conditional above.

reference for is_home() and strip_shortcodes()

just for fun:

truth table:

0 0 0 1 = ( 0 || 0 ) && ( 1 && 0 ) = 0 && 1 = 0

0 0 1 0 = ( 0 || 0 ) && ( 0 && 1 ) = 0

0 0 1 1 = 0

0 1 0 0 = 0

... = 0

1 0 0 0 = 1

0 1 0 0 = 1

1 1 0 0 = 1

... = 0

Myers.

I guess you have this code on your index.php file or whathever file displaying content in homepage:

if ( has_post_thumbnail() ) {
 the_post_thumbnail(); 
} else {
 get_the_image( array('size' => 'thumbnail',
                      'image_class' => 'wp-post-image'));   
}

I had tested in mine. I do not use the code above. I only use this in functions.php

// This theme displays custom size (page-single) featured image on the Post's  page

function InsertFeaturedImage($content) {

global $post;

$original_content = $content;

if ( current_theme_supports( 'post-thumbnails' ) ) {

    if ((is_page()) || (is_single())) {

        $content = get_the_image( array( 'size' => 'full' ) );
        $content .= $original_content;
    }
}
return $content; 
}
add_filter( 'the_content', 'InsertFeaturedImage' );
