Getting image thumb from the post

  • Hey,

    I am trying to get the image thumb added in the post at the time of adding the post.

    I am using the_post_thumbnail(‘thumbnail’) function however it is showing the featured image. I would like to get the image from the content. How can i do this with WordPress default functions.

    Please help

    Thanks
    Zack

  • I don’t think there is a WordPress function for that but I use this function to get the first image from the post content:

    function get_first_image() {
    global $post;
    $first_image = '';
    ob_start();
    ob_end_clean();
    $output = preg_match_all('/<img.+src=[\'"]([^\'"]+)[\'"].*>/i', $post->post_content, $matches);
    $first_image = $matches[1][0];

    if(empty($first_image)){ //return false if no image is found
        $first_image = false;
    }

    return $first_image;
}
