Wordpress - Get tag id by slug

I am trying to get id\name of tag by it slug.

Thats my code:

$tag = get_term_by('slug', 'hedoms', 'post_tag');
$tag_id = $tag->term_id;

<h1><?php echo $tag->name;?></h1>

I took it from here:

I have tag with the slug **hedoms** but the `<h1>` is empty, it not returns the value. I have tried this function (get_term_by) with category - and same result.

the 2nd field is the slug.


But if i do it with id and not slug, it works fine:

$tag_id = get_term_by('id', 97, 'post_tag');
echo $tag_id->name;


It look like the get_term_by recognize only 'id' as field.


What i miss here? it should be on loop or something ?

The file i trying to do it is `archive-product.php` of Woocommerce.

$tag = get_term_by('slug', ' hedoms','post_tag');

$tag_id = $tag->term_id;

OK i have found the solution.

I set on the get_term_by the taxonomy 'post_tag' instead 'product_tag' as it woocommerce tags. Next time i will look carefully on the url of the wp-admin when i am looking on taxonomy page:

...wp-admin/edit-tags.php?taxonomy=product_tag&post_type=product

So the code should be like that:

$tag = get_term_by('slug', $slug, 'product_tag');
$tag_name = $tag->name;

<h1><?php echo $tag_name; ?></h1>


Solved.
