Use post tags for meta keyword content

Question

Seems this should be super simple, but I can't find the right API function to make it work...

I'd like to use a posts tags to populate the keywords meta content...

<meta name="keywords" content="tags from post go here seperated by commas">

I've tried this but it creates a link list of each post tag...

<meta name="keywords" content="<?php echo the_tags('',' , '); ?>" />

Answer 1

You need to use the template function get_the_tags to fetch the data instead of letting WordPress output it for you. You can then loop through this array and output the list however you would like:

<?php
if ( $posttags = get_the_tags() ) {
    foreach($posttags as $tag)
        echo $tag->name . ' '; 
}
?>

Answer 2

the_tags() automatically displays a link to each post tag. You could use get_the_tags() which returns an array of tag objects, which you can then loop through and get the name of the tag.

Answer 3

Try something like:

<?php
  $postTags = get_the_tags();
  $tagNames = array();
  foreach($postTags as $tag) {
    $tagNames[] = $tag->name;
  }
?>

<meta name="keywords" content="<?php echo implode($tagNames,","); ?>" />
