Wordpress：用户组打印两次

Question

I have this following code that is printing twice the user group. Thanks in advance.

<?php
$terms = array();
        $terms_tags = get_the_terms( $current_user->ID, array( 'user-group' )   ); 
        foreach ( $terms_tags as $term_tag ) {
          $terms[$term_tag->slug] = $term_tag->name;
          echo $term_tag->slug. ' ';
        }
?>

Answer 1

The WordPress docs are indicating that the second parameter for get_the_terms() should be a string, not an array. Could you check this?

Try it like this:

<?php
  $terms = array();
  $terms_tags = get_the_terms( $current_user->ID, 'user-group' ); 
  foreach ( $terms_tags as $term_tag ) {
    $terms[$term_tag->slug] = $term_tag->name;
    echo $term_tag->slug. ' ';
  }
?>

By now this is the only "problem" i see in your code.
