I've implemented this update class in my plugin, but for some reason the update banner isn't diplayed.

Within the class Wp_License_Manager_Client I have this code:

add_filter('pre_set_site_transient_update_plugins', array($this, 'check_for_update'));

that fire the function check_for_update, in particular the following line is called:

$plugin_slug = plugin_basename($this->plugin_file);

$transient->response[$plugin_slug] = (object) array(
    'new_version' => $info->version,
    'package'     => $info->package_url,
    'slug'        => $plugin_slug,
    'url'         => $info->package_url
);

This is the var_dump($transient->response[$plugin_slug]):

object(stdClass)#8891 (4) { 
    ["new_version"]=> string(5) "1.0.1" 
    ["package"]=> string(107) "https://example.com/api/license-manager/v1/get?p=my-plugin&[email protected]&l=123456789%24" 
    ["slug"]=> string(47) "my-plugin/public/class-wp-api-client.php" 
    ["url"]=> string(107) "https://example.com/api/license-manager/v1/get?p=my-plugin&[email protected]&l=123456789%24" 
    }

I replaced the values for privacy, but as you can see the object is correctly created.

The situation in the panel is the following:

As you can see from the image Wordpress show me that there is one update, but when I click on "updates", it says that all the plugins are updated. Also, I get the update badge notification only when I clear the cache.

What is going on?

PS: I'm testing this in my localhost with XAMPP and wordpress version is 6.0.1.

  • Which cache plugin you are using can you specify that.

  • So what this line means " Also, I get the update badge notification only when I clear the cache. " can you explain a bit.

  • @Prits I usally clear the cache using the console -> network -> disable cache

  • That cache didn't create issue with this.

I ran across this a few weeks ago with a client site - maybe this will help.

 /**
 * Debug Pending Updates
 *
 * Crude debugging method that will spit out all pending plugin
 * and theme updates for admin level users when ?debug_updates is
 * added to a /wp-admin/ URL.
 */
function debug_pending_updates() {

    // Rough safety nets
    if ( ! is_user_logged_in() || ! current_user_can( 'manage_options' ) ) return;
    if ( ! isset( $_GET['debug_updates'] ) ) return;

    $output = "";

    // Check plugins
    $plugin_updates = get_site_transient( 'update_plugins' );
    if ( $plugin_updates && ! empty( $plugin_updates->response ) ) {
        foreach ( $plugin_updates->response as $plugin => $details ) {
            $output .= "<p><strong>Plugin</strong> <u>$plugin</u> is reporting an available update.</p>";
        }
    }

    // Check themes
    wp_update_themes();
    $theme_updates = get_site_transient( 'update_themes' );
    if ( $theme_updates && ! empty( $theme_updates->response ) ) {
        foreach ( $theme_updates->response as $theme => $details ) {
            $output .= "<p><strong>Theme</strong> <u>$theme</u> is reporting an available update.</p>";
        }
    }

    if ( empty( $output ) ) $output = "No pending updates found in the database.";

    wp_die( $output );
}
add_action( 'init', 'debug_pending_updates' );

Append your admin url as follows:

For example: https://yoursite.com/wp-admin/?debug_updates

Tutorial you are using is 7 years old, I wouldn't bother wit it as it is probably not fully compatible with latest WP-Core and auto-updates.

I'm using free (MIT license) and regularly maintained Plugin Update Checker & WP Update Server WP libraries for my Warp iMagick plugin.

Check this tutorial to add licencing.

You can use this code to check if plugin updates is available :

add_action('admin_menu', array($this,'register_test_menu_page'));

public function register_test_menu_page(){
    add_menu_page('Test', 'Test Menu', 'manage_options', 
     'test_user_menu', array($this,'test_user_menu_fun'), null, 4);
}

public function test_user_menu_fun(){
    $update_plugins = get_site_transient( 'update_plugins' );
    foreach ($update_plugins->response  as $key => $value) {
        var_dump($value->slug);
    }   
}

it provides an array you can easily show that in the list in your setting page.

  • The code you provided returns an empty response, but as you can see from my question the transient is correctly valorized

  • Can you check your wp_options table with the key '_site_transient_update_plugins' and double check if you see in correct database and also add the SS for plugin update available .

  • The value of _site_transient_update_plugins is the following: pastebin.com/WLZQeTQP also I don't know what does SS means

  • The link is not available and add SS means Screenshot of that meta key wp_options table.
