157 views

I am trying to get the current user in WordPress. My code is in below:

<?php
    include('/wp-admin/includes/user.php');
    $current_user = wp_get_current_user(); 
    echo 'Username: ' . $current_user->user_login;
?>

but I get the following error:

Fatal error: Call to undefined function wp_get_current_user() in /membri/mysite/wordpress/getUser.php on line 3

How can I resolve it?

In your functions.php, you can do this:

function my_theme_get_user_id() {
    global $current_user;

    echo 'The current logged in user ID is: ' . $current_user->ID;
}

then, use an action hook or a filter to use it were needed.

In your theme, under the wp-content/themes/ directory, you can simply do this directly in any of your files for view:

global $current_user;
echo 'The current logged in user ID is: ' . $current_user->ID;

I want to display all the existing categories in my Wordpress page in the bottom of the content and the selected category will be in bold style, as follows:

For example, for an existing post if I selected category2 of 3 existing, then it show like this

category1 category2 category3

<div class="entry-meta">
<span class="term-links">
<?php foreach ( get_the_terms( $post->ID, 'category') as $term ) : 
?>
<a href="<?php echo esc_url( get_term_link( $term->term_id ) ) 
?>"><span class="<?php echo $term->slug ?>"><?php echo $term->name ?>
</span></a>
<?php endforeach; ?>
</span>

<style>
.term-links .category2 {
display: inline-block;
font-weight:bold;
</style>

In the above code only display the selected category, not showing the all category. How can I do this?
