Set a default featured image

    I’m using post feeds in Meta Slider and it requires that the post (custom post in my case) has a featured image. So when a transparent png is set for each post, the slider works fine.

    How can I automatically set the featured image for a custom post type to transparent.png

    There’s a plugin that sounds like it does what you need:

    Thanks Alex. I have tried to use this plugin but it seems to have some bugs in the latest version. Is there an alternative?

    I’ve come up with this, but its obviously not quite right – not sure also at what point it applies the image

    add_filter('post_thumbnail_html', 'wt_modify_post_thumbnail_html', 99, 5);
function wt_modify_post_thumbnail_html() {
if ( has_post_thumbnail() &&  get_post_type() == 'testimonials' )  {
   the_post_thumbnail();
} else {
    echo '<img src="' . get_bloginfo( 'stylesheet_directory' ) . '/images/transparent.png" />';
}
}

    Hello powerj,

    The filter applies the image when there was no featured image is applied post in post type=”testimonials”.

    Thanks

    filter should return the results, not echo it;

    try to modifiy your code accordingly:

    add_filter('post_thumbnail_html', 'wt_modify_post_thumbnail_html');
function wt_modify_post_thumbnail_html( $html ) {
if ( !$html &&  get_post_type() == 'testimonials' )  $html = '<img src="' . get_bloginfo( 'stylesheet_directory' ) . '/images/transparent.png" />';
  return $html;
}
