iframe embed video with php variable as source not working

Question

I have a variable that stores an array, and in that array there is a YouTube url.

When I var dump

$node->field_video_link

It looks like the following:

array(1) { ["und"]=> array(1) { [0]=> array(5) { ["video_url"]=> string(43) "https://www.youtube.com/watch?v=SC9BgH_L29c" ["thumbnail_path"]=> string(61) "public://video_embed_field_thumbnails/youtube/SC9BgH_L29c.jpg" ["video_data"]=> string(34) "a:1:{s:7:"handler";s:7:"youtube";}" ["embed_code"]=> NULL ["description"]=> NULL } } }

Now, I want to use the video link as an iframe so that users can watch through the site and I did it like the following:

$sample1_video_link = (isset($node->field_video_link['und'])) ? file_create_url($node->field_video_link['und'][0]['video_url']) : '';

<iframe width="420" height="315"
src="<?php print $sample1_video_link; ?>">
</iframe>

When I go view the page, the video thumbnail does not appear, and instead, I see a message that says "www.youtube.com refused to establish connection"

However, if I grab a random URL from youtube, the iframe works.

The error looks like in the below image:

Anything I am possibly doing wrong?

EDITED:

I now use echo instead of print and when I reload the page, still the same error.

<iframe src="<?php echo $sample1_video_link; ?>"></iframe>

When I inspect the page, I see the following:

<iframe src="https://www.youtube.com/watch?v=SC9BgH_L29c"></iframe>

Which is apparently the same value being stored in the array.

What does file_create_url do? I'm not familiar with that function — Stevish

use echo instead of print:

src="<?php echo $sample1_video_link; ?>">

also youtube generates embedding url (share below the video) use that one instead they also generate an example iframe structure :

<iframe width="560" height="315" src="https://www.youtube.com/embed/SC9BgH_L29c" frameborder="0" allow="accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe>

going by your code you can jsut add the video id after "https://www.youtube.com/embed/"

or

src="<?php echo str_replace("https://www.youtube.com/watch?v=","https://www.youtube.com/embed/",$sample1_video_link; ?>">

Or the shorthand version <?= $sample1_video_link ?>

I still see exactly the same error if I echo the variable

youtube generates embedding links maybe this helps : youtube.com/embed/SC9BgH_L29c

I cannot use the url directly in the html. It needs to come from the variable as it is because its dynamic content.
