My Child-theme funtions.php file and shortcode is [my-shortcode]

<?php

function wpb_postsbycategory() {
// the query
$the_query = new WP_Query( array( 'category_name' => 'yhteystiedot', 'posts_per_page' => 1, 'orderby' => 'post_date', 'order' => 'DESC' ) ); 
 
// The Loop
if ( $the_query->have_posts() ) {
    $string .= '<div class="postsbycategory widget_recent_entries">';
    while ( $the_query->have_posts() ) {
        $the_query->the_post();
        
		
            $string .= '<div>'.'' .get_the_content() .'</div>';
            $string = apply_filters('the_content', $string);
	$string = str_replace(']]>', ']]>', $string);
            }
    } else {
    // no posts found
}
$string .= '</div>';
 
return $string;
 
/* Restore original Post Data 
wp_reset_postdata();*/
}
// Add a shortcode
add_shortcode('my-shortcode', 'wpb_postsbycategory');

add_filter( 'widget_text', 'shortcode_unautop');
add_filter( 'widget_text', 'do_shortcode');

Here is the code of some of my php file(UserRecord.php) that is_user_logged_in() is not working.

/** public_html/wp-content/plugins/SLMS/UserRecord.php */
if ( !is_user_logged_in() ) {
wp_redirect( home_url() );
exit;
}
elseif(isset($_POST[‘saveUserBtn’]) and $_SERVER[‘REQUEST_METHOD’] == “POST”) {
insertRecord();

/**
insertRecord();
echo “working” ;
*/

}

elseif(isset($_POST[‘searchUNBtn’]) and $_SERVER[‘REQUEST_METHOD’] == “POST”) {
searchUNRecord();

/**
searchUNRecord();
echo $_POST[‘searchUN’];
echo “Success”;*/
}

elseif(isset($_POST[‘updateUserBtn’]) and $_SERVER[‘REQUEST_METHOD’] == “POST”) {
updateRecord();

/**
updateRecord();
echo $_POST[‘ID’];
echo “Update Status”;*/
}

Produces a fatal error in geolocation line:182 undefined function is_user_logged_in()

Currently tested and repeated in two instances – development environment

researched: Our reference

<p>
<?php
if ( is_user_logged_in() ) {
    echo 'Welcome, registered user!';
} else {
    echo 'Welcome, visitor!';
}
?>
</p>

Which works as expected on all pages other than the events list page.

When the events list view as is set to List, is_user_logged_in() always returns false regardless of whether a user is logged in or not. However, if the events list view is set to Month or Day, is_user_logged_in() returns the expected value depending on the user’s logged in status.

Is this a bug or is there something I don’t understand about how the events list view is implemented?

I’m working on multiplesite on wordpress based on sub domain basis. How can I disable the WP Super cache for all the subdomains.

My another question is “WP Super Cache cannot tell logged-in users properly” – means is_user_logged_in() seems to be not working if WPSC is enabled.

Need help urgently

}

I’m using Buddypress for my website. I have created a notice for my users and I’m using this code:

<?php if ( is_user_logged_in() ) {
echo '<span class="notice-user">
<div>
<p> You can send friend requests and Messages to this user</p>
</div>
<span>';
}
?>

While this is working absolutely fine for the visitors, This code also shows up the notice if the user visits his OWN profile.

So, If user XYZ visits ABC. This notice should be there but if user XYZ visits his own profile i.e. XYZ’s profile, this notice should not be there.

Any idea How can I do that?

Thanks in advance!

I have found this weird issue. Im using this function to display a welcome message for logged in users. Everything works, logout, login, etc.

After login on My Account page the Top Bar is succesfully updated and the welcome message appears, but if I go to the front page the Welcome message is not appearing. It is displayed on every other page, shop, posts, categories, etc. Just not on the front page.

If I refresh the front page with CTRL+R the welcome message appears correctly.

Default State

Logged In

I have disabled caching for front page too.

Also tried this code, to flush it on login:

add_action('wp_login', 'mj_flush_w3tc_cache');

function mj_flush_w3tc_cache()
{
	if (function_exists('w3tc_pgcache_flush_post')) {
		w3tc_pgcache_flush_post(233);
	}
}

Thanks for the help

If I refresh the page, the function or the wordpress_logged_in isset comprobation works great.

Any ideas? I’m driving myself crazy…

Thanks!
