将帖子术语分别插入DB

I am trying to add tags to my videos as terms and the problem is if i have more tags for one video they are stored in one variable and passed to the DB as a group, what i need to have is that every tag gets inserted to the db separately

Right now its like this: Example :

          $tags = #tag1 #tag2 #tag3
          wp_insert_term( $tags, 'post_tag'); 

In the db it looks like

          term_id           name              slug
             1         #tag1 #tag2 #tag3  tag1-tag2-tag3

and i would need it to be like this

          term_id           name              slug
             1              #tag1             tag1
             2              #tag2             tag2
             3              #tag3             tag3

Wordpress doesn't know what's your intention, so

$tags = '#tag1 #tag2 #tag3'

is actually one variable. So, say it different, try the snippet below

$tags = array('#tag1', '#tag2', '#tag3', '#tag4', '#tag5');
foreach($tags as $tag){
    wp_insert_term(trim($tag), 'post_tag'); // just in case, use trim() for cleaning
}

Demo

If you'd like to use explode(), be sure to clean each value using trim(); or better said be sure you don't have an empty string.

Try this:

$tags = "#tag1 #tag2 #tag3";
$tagsArray = explode(" ", $tags);
foreach($tagsArray as $tag)
{
    wp_insert_term( $tag, 'post_tag'); 
}
