Exclude excerpt from wordpress wp_query - php

Question

Hellow everyone!
I am showing blog of posts in additional wp template and everything works fine, but I've made some kind of gallery from it, and I don't need to show anything except gallery and title.
Inside posts I have this:
[gallery ids="1618,...,1634"]
<h2>...</h2>
<p>...</p>
text without format, etc.
As you can see, I am using a gallery shortcode. I need it to be shown, but all other content to be excluded from the loop.
Really appreciate your help in this question...
My template code:
<?php
/*
* Template name: Блог
*/
$current_page = (get_query_var('paged')) ? get_query_var('paged') : 1;
$args = array(
'posts_per_page' => 9,
'paged' => $current_page,
'cat' => 8
);
query_posts( $args );
$wp_query->is_archive = true;
$wp_query->is_home = false;
while(have_posts()): the_post();
?>
<div class="foto_posts">
<?php the_content() ?>
<?php echo '' . get_the_title() . '';?>
</div>
<?php
endwhile;
if(function_exists('page_navi_slider')) page_navi_slider();

Answer 1

try to replace <?php the_content() ?> to <?php the_title() ?>

Answer 2

if you just want to show gallery shortcode try this
replace
<?php the_content() ?>
to
$pattern = get_shortcode_regex();
preg_match('/'.$pattern.'/s', $post->post_content, $matches);
if (is_array($matches) && $matches[2] == 'gallery') {
$shortcode = $matches[0];
echo do_shortcode($shortcode);
}

Try this for getting galleries and videos use the get_post_meta_key()
<?php get_post_meta($post_id,'key_name',1);?>
If it returns an array then traverse that array to get the images link and video links
add_shortcode('gallery', 'gallery_shortcode_fancybox');
function gallery_shortcode_fancybox($attr) {
$attachment_ids = explode(',',$attr['ids']);
$args = array(
'post__in' => $attachment_ids,
//'cat' => 8 if category needs to be shown pass it in shortcode , same as ids
);
$gallery_posts = query_posts( $args );
foreach ($gallery_posts as $key => $value) {
//do the stuff here
echo '<h2>'. $value->post_title;'</h2>';
$feat_image = wp_get_attachment_url( get_post_thumbnail_id($value->ID);
echo '<p><img src="'.$feat_image.'" ></p>';
}
}
