WordPress get_the_tags() function can allow us to get all tags of a post. We can control these tags by our needs. In this tutorial, we will introduce how to use this function.
Syntax
get_the_tags( int $id )
Get all tags of a post.
$id: the post id.
If this function is used in main loop. the $id is not need, otherwise, you should assign a post id.
How to use get_the_tags()?
We can use code below to get all tags of a post.
<?php
$posttags = get_the_tags(14);
if ($posttags) {
foreach($posttags as $tag) {
echo $tag->name . ' ';
}
}
?>Where $posttags is an array, which contains some WP_Term Object object. For example:
Array
(
[0] => WP_Term Object
(
[term_id] => 108
[name] => tag-1
[slug] => tag-1
[term_group] => 0
[term_taxonomy_id] => 109
[taxonomy] => post_tag
[description] =>
[parent] => 0
[count] => 1
[filter] => raw
[object_id] => 24
)
[1] => WP_Term Object
(
[term_id] => 109
[name] => tag-2
[slug] => tag-2
[term_group] => 0
[term_taxonomy_id] => 110
[taxonomy] => post_tag
[description] =>
[parent] => 0
[count] => 1
[filter] => raw
[object_id] => 24
)
)
Then we can use these WP_Term Object in our wordpress site.
