Split Content and Gallery

by

Is there a way to split up the post content and the gallery short code. I want to display the gallery outside my normal content no matter how or where it is placed. I can use this to get the shortcode itself:

if(has_shortcode(get_the_content(), 'gallery')){
    $pattern = get_shortcode_regex(); 
    preg_match("/$pattern/s", get_the_content(), $matches);
    echo do_shortcode($matches[0]);
}

But this doesn’t work if the gallery short code isn’t the first instance. Is there a way to split my content and gallery up completely?

Edit: I have a semi-solution but it seems like a long winded way to go about it. It first grabs the first shortcode in the post (which needs to be fixed since I only want the “Gallery” shortcode) then removes all shortcodes from the content (again, not really what I want to do.

<?php if(has_shortcode(get_the_content(), 'gallery')) : ?>
    <?php 
        $pattern = get_shortcode_regex(); 
        preg_match("/$pattern/s", get_the_content(), $matches);
    ?>
    <div id="content">
        <?php echo strip_shortcodes(get_the_content()); ?>
    </div>
    <div id="gallery">
        <?php echo do_shortcode($matches[0]); ?>
    </div>
<?php endif; ?>

Edit #2 – Ok, I’ve been able to only get gallery shortcodes in the post. I’ve also added a filter to remove the gallery shortcode form the_content() – the problem is that its not necessarily removing the shortcode since it does post it, but its not allowing me to run “do_shortcode()”

Functions.php

function remove_gallery($content) {
    global $post;

    if($post->post_type == 'artcpt')
        remove_shortcode('gallery', $content);

    return $content;
}
add_filter( 'the_content', 'remove_gallery', 6);

The Loop

<?php preg_match('/\]+\]/', get_the_content(), $matches); ?>
<div id="content">
    <?php the_content(); ?>
</div>
<div id="gallery">
    <?php echo do_shortcode($matches[0]); ?>
</div>

in The Loop it will return my short code Twice (i’m on a single page, should be looped twice – so its not running do_shortcode()). Not sure why.

Open to anybody who can simplify this but here’s what I came up with that worked for me.

First thing’s first – get the gallery, using get_post_gallery(), as soon as the loop starts:

<?php if( have_posts() ) : ?>

    <?php while( have_posts() ) :
            the_post();
            $gallery = get_post_gallery();
            $content = strip_shortcode_gallery( get_the_content() );
    ?>

        <div id="content">
            <?php echo $content; ?>
        </div> <!-- id="content" -->

        <div id="gallery">
            <?php echo $gallery; ?>
        </div> <!-- id="gallery" -->

    <?php endwhile; ?>

<?php endif; ?>

strip_shortcode_gallery() Function – functions.php

function strip_shortcode_gallery( $content ) {
    preg_match_all( "https://wordpress.stackexchange.com/" . get_shortcode_regex() . '/s', $content, $matches, PREG_SET_ORDER );

    if ( ! empty( $matches ) ) {
        foreach ( $matches as $shortcode ) {
            if ( 'gallery' === $shortcode[2] ) {
                $pos = strpos( $content, $shortcode[0] );
                if( false !== $pos ) {
                    return substr_replace( $content, '', $pos, strlen( $shortcode[0] ) );
                }
            }
        }
    }

    return $content;
}
