wp is_user_logged_in 在主页上不起作用

Question

I'm having an issue with is_user_logged_in() and was hoping to get some help.... the main site URL is http://www.thecuriosityworkshop.com I'm using is_user_logged_in() to echo certain content to signed in users, and it all works fine within the inner pages, but doesn't work on the home page.

Even when I log in as an admin and visit the home page is_user_logged_in() shows false , but when I go to any of the inner pages, is_user_logged_in() shows true . Any idea what is happening?

For the sake of testing I'm just doing the following:

if ( is_user_logged_in() ) {
  echo 'true';
} else {
  echo 'false';
}

Use this code:

//variable for check user logged in
$isUserLogged = false;

//Checks if the current visitor is a logged in user.
if ( !function_exists('is_user_logged_in') ) {

$user = wp_get_current_user();

    if ( !empty($user->ID) ) {
       $isUserLogged = true;
    }

} else {

    if ( is_user_logged_in() ) {
        $isUserLogged = true;
    }
}

I had this same issue and when I changed my .htaccess file to disable all caching it solved the problem. This is the best code I have found for this:

    #prevent caching
    <filesMatch "\.(html|htm|js|css)$">
     FileETag None
     <ifModule mod_headers.c>
      Header unset ETag
      Header set Cache-Control "max-age=0, no-cache, no-store, must-revalidate"
      Header set Pragma "no-cache"
      Header set Expires "Wed, 11 Jan 1984 05:00:00 GMT"
    </ifModule>
  </filesMatch>

whether the above code works in your .htacess file or not, try and go to browser tools -> clear browsing data and delete all cache before logging in, that should do it.

I browsed around a long time, stuck on this.

I had made an extra page, where I used WordPress-authentication.

This was basically it:

https://example.org/vips-only/login.php

require_once( $_SERVER['DOCUMENT_ROOT'] . '/wp-load.php' );
defined( 'ABSPATH' ) or die( 'This page cannot be accessed directly.' );

if( is_user_logged_in() ){
  echo 'You are logged in, mate';
} else {
  $redirect_to = get_site_url() . '/vips-only/welcome.php';
  wp_login_form([
    'redirect' => $redirect_to
  ]);
}

For some reason I couldn't get that is_user_logged_in() to work. Even if I first logged in via the 'real' WordPress-login form (and not this custom one I had setup).

What solved it for me was to create a new file and copy everything over in that, like: https://example.org/vips-only/new-login.php . I have no idea why that worked, but it did.

It might be cookie-related. It might be related to a plugin (I was using WPS Hide Login ). I thought the problem would return, but it hasn't yet.

Try to put this in header.php :

if ( is_user_logged_in() ) {
    $logged = TRUE
} else {
    echo 'false';
    $logged = FALSE
}

Then just add this condition on any content :

if($logged) {
    echo 'Logged in';
} else {
    echo 'not logged in'; 
}
