auto generate thumbnail from video by scanning whole post – lost plug-in

Hey Adam,

I think you were really close to getting it working when you tried the change you mentioned. Like you mentioned, since the field only has the Vimeo ID you need to make one more small change. Instead of changing it to this:

// Gets the post's content
$video_key = 'vimeo_id';
$markup = get_post_meta($post_id, $video_key, true);
$new_thumbnail = null;

Try changing it to this:

// Gets the post's content
$video_key = 'vimeo_id';
$markup = 'https://vimeo.com/'.get_post_meta($post_id, $video_key, true);
$new_thumbnail = null;

Now the plugin should know it’s from Vimeo.

Perfect! Thank you so much, it works a charm.

I do have a further question though. Ideally what I’m trying to set up is an action that checks to see if there is a value entered into the vimeo_id field and if not, then use a value entered into a youtube_id field.

In the original template, I had this:

<?php if( $project_item = get_post_meta($post->ID, 'vimeo_id', true) ): ?>
<iframe src="https://player.vimeo.com/video/<?php echo $project_item; ?>?title=0&byline=0&portrait=0" width="508" height="286" frameborder="0" webkitAllowFullScreen allowFullScreen></iframe>
<?php else: ?>
 <iframe width="508" height="286" src="https://www.youtube.com/embed/<?php echo get_post_meta($post->ID, 'youtube_id', true);?>" frameborder="0" allowfullscreen></iframe>
<?php endif; ?>

Do you have any idea how this would work with your plug-in? Would I need to add something similar to the code you’ve provided for the youtube_id field as well? If so, if you could point out where I’d be grateful and am more than happy to pay you for your time.

Looking at the other other thread again, I’m thinking something like this would work:

// gets custom field data
$vimeoid = get_post_meta($post_id, 'vimeo_id', true);
if($vimeoid) {
	$markup = 'https://vimeo.com/'.get_post_meta($post_id, $vimeoid, true);
} else {
$youtubeid = get_post_meta($post_id, 'youtube_id', true);
if($youtubeid) {
	$markup = 'https://youtu.be/'.get_post_meta($post_id, $youtubeid, true);
}
$new_thumbnail = null;

Unfortunately it doesn’t. Does anyone know what I’m doing wrong?

Adding in another } satisfies the WordPress system but not the plug-in. Code that isn’t woking currently looks like this:

// gets custom field data
$vimeoid = get_post_meta($post_id, 'vimeo_id', true);
if($vimeoid) {
	$markup = 'https://vimeo.com/'.get_post_meta($post_id, $vimeoid, true);
} else {
$youtubeid = get_post_meta($post_id, 'youtube_id', true);
if($youtubeid) {
	$markup = 'https://youtu.be/'.get_post_meta($post_id, $youtubeid, true);
}
}
$new_thumbnail = null;

Does anyone have any idea on how I can get the Video Thumbnails plug-in to search 2 custom post fields as described above? I am more than happy to pay someone for their time and expertise.

I think you’re pretty close, try changing ‘https://youtu.be/’ to ‘https://www.youtube.com/watch?v=’

I don’t think it currently checks for youtu.be links, but it’s something I should add. PS – Donations are always welcome!

Hi Sutherland,

Thanks a lot for your input. Unfortunately that slight change of code hasn’t fixed it. I still get the ‘We didn’t find a video thumbnail for this post. (be sure you have saved changes first)’ message for projects that have a youtube_id rather than a vimeo_id.

Ah, I just realized you’re using get_post_meta() twice for each source and asking for the wrong field the second time, try this.

// gets custom field data
$vimeoid = get_post_meta($post_id, 'vimeo_id', true);
if($vimeoid) {
	$markup = 'https://vimeo.com/'.$vimeoid;
} else {
$youtubeid = get_post_meta($post_id, 'youtube_id', true);
if($youtubeid) {
	$markup = 'https://www.youtube.com/watch?v='.$youtubeid;
}
}
$new_thumbnail = null;

Amazing, thank you Sutherland. It works a treat. Now if I can just get a few other bits and bobs working I should be in a position to give you a donation.
