WordPress get_the_tags() and get_tags() both can get wordpress post tags, however, there are some differences between them. In this tutorial, we will use some example codes to help you to understand them.
get the tags():
1) This function is often used in The Loop, If you want to used in other place, you should give a post id.
2) It gets all tags of one post
Here is an example:
<?php if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>
<?php
$posttags = get_the_tags();
if ($posttags) {
foreach($posttags as $tag) {
echo $tag->name . ' ';
}
}
?>
<?php endwhile; endif; ?>get_tags():
1) This function can be used in anywhere
2) It gets all tags saved in wordpress database,not belong to one post
Here is an example:
<?php
$posttags = get_tags();
if ($posttags) {
foreach($posttags as $tag) {
echo $tag->name . ' ';
}
}
?>
