How to: Get the first image from the next and previous post in single.php?

  • I know I can call the function following:

    function catch_that_image() {
    global $post, $posts;
    $first_img = ”;
    ob_start();
    ob_end_clean();
    $output = preg_match_all(‘/<img.+src=[\'”]([^\'”]+)[\'”].*>/i’, $post->post_content, $matches);
    $first_img = $matches [1] [0];

    if(empty($first_img)){ //Defines a default image
    $first_img = “/images/default.jpg”;
    }
    return $first_img;
    }

    But I try to using this function in single.php or posting page. It was display only image at own ID.

    However, I need to call an image from next and previous post of this ID.

    Can I do it?

    Thanks!

    Thanks!!

    However, I don’t want to using Featured Image. I want to using a first image that found in next and previous post to display in currently post.

    Yes, use regex there to get first one.

    Can you help me to write function of it?

    I really doubt about function. I try to write and edit some value but it not return a value or get errors not displayed next and previous image by post.

    This is my single.php code:

    It seems to display information of own page only.

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

<?php /* Start the Loop */ ?><?php while ( have_posts() ) : the_post(); ?>

<?php get_template_part( 'content', get_post_format() ); ?>
<?php endwhile; ?>

<?php /* Start the Loop */ ?><?php if ( have_posts() ) while ( have_posts() ) : the_post(); ?>
<div class="productwarp-feature">

<div class="productimage">

<div align="center"><a href="<?php the_permalink(); ?>" title="<?php the_title(); ?>" rel="bookmark"><img src="<?php echo catch_that_image() ?>" style="width: 80px; max-height: auto !important; height: 80px; max-width: auto !important; margin-left: -30px;"></a></div>

</div>

<div class="productinner"><a href="<?php the_permalink(); ?>" title="<?php the_title(); ?>" rel="bookmark"><?php the_title(); ?></a></div>

<p class="blurb" style="text-align: center;"><a href="<?php echo catch_that_url() ?>" rel="nofollow" title="Go to Store" class="purelycss_fusion_button color_green" style="text-decoration: none; color: white;" target="_blank">Shop Now</a></p>

</div>
<?php endwhile; ?>
</div>
