I am facing an issue of update now button not showing up even if there is an update for a plugin. The following is the method that checks the updates for the plugin
public function check_update( $_transient_data ) {
global $pagenow;
if ( ! is_object( $_transient_data ) ) {
$_transient_data = new stdClass;
}
if ( 'plugins.php' == $pagenow && is_multisite() ) {
return $_transient_data;
}
if ( ! empty( $_transient_data->response ) && ! empty( $_transient_data->response[ $this->name ] ) && false === $this->wp_override ) {
return $_transient_data;
}
$version_info = $this->get_cached_version_info();
if ( false === $version_info ) {
$version_info = $this->api_request( 'plugin_latest_version', array( 'slug' => $this->slug, 'beta' => $this->beta ) );
error_log('version info from api'.wp_json_encode($version_info));
$this->set_version_info_cache( $version_info );
}
if ( false !== $version_info && is_object( $version_info ) && isset( $version_info->new_version ) ) {
if ( version_compare( $this->version, $version_info->new_version, '<' ) ) {
$_transient_data->response[ $this->name ] = $version_info;
}
$_transient_data->last_checked = time();
$_transient_data->checked[ $this->name ] = $this->version;
}
return $_transient_data;
}
This is the method that gets the info related to version info in the cache:
public function get_cached_version_info( $cache_key = '' ) {
if( empty( $cache_key ) ) {
$cache_key = $this->cache_key;
}
$cache = get_option( $cache_key );
if( empty( $cache['timeout'] ) || time() > $cache['timeout'] ) {
return false; // Cache is expired
}
return json_decode( $cache['value'] );
}
And this is the method which sets the version info in the cache:
public function set_version_info_cache( $value = '', $cache_key = '' ) {
if( empty( $cache_key ) ) {
$cache_key = $this->cache_key;
}
$data = array(
'timeout' => strtotime( '+3 hours', time() ),
'value' => json_encode( $value )
);
update_option( $cache_key, $data, 'no' );
}
When I remove/delete the update_plugins transient the updates started to show up but again after some time the again the update now button disappears only showing that there is an update for the plugin. I tried to use the following but it is not a recommendable approach:
public function force_update_check() {
delete_site_transient( 'update_plugins' );
}
Therefore a but help needed to fix the issue. This is the method for showing update notification
public function show_update_notification( $file, $plugin ) {
if ( is_network_admin() ) {
return;
}
if( ! current_user_can( 'update_plugins' ) ) {
return;
}
if( ! is_multisite() ) {
return;
}
if ( $this->name != $file ) {
return;
}
// Remove our filter on the site transient
remove_filter( 'pre_set_site_transient_update_plugins', array( $this, 'check_update' ), 10 );
$update_cache = get_site_transient( 'update_plugins' );
$update_cache = is_object( $update_cache ) ? $update_cache : new stdClass();
if ( empty( $update_cache->response ) || empty( $update_cache->response[ $this->name ] ) ) {
$version_info = $this->get_cached_version_info();
if ( false === $version_info ) {
$version_info = $this->api_request( 'plugin_latest_version', array( 'slug' => $this->slug, 'beta' => $this->beta ) );
$this->set_version_info_cache( $version_info );
}
if ( ! is_object( $version_info ) ) {
return;
}
if ( version_compare( $this->version, $version_info->new_version, '<' ) ) {
$update_cache->response[ $this->name ] = $version_info;
}
$update_cache->last_checked = time();
$update_cache->checked[ $this->name ] = $this->version;
set_site_transient( 'update_plugins', $update_cache );
} else {
$version_info = $update_cache->response[ $this->name ];
}
// Restore our filter
add_filter( 'pre_set_site_transient_update_plugins', array( $this, 'check_update' ) );
if ( ! empty( $update_cache->response[ $this->name ] ) && version_compare( $this->version, $version_info->new_version, '<' ) ) {
// build a plugin list row, with update notification
$wp_list_table = _get_list_table( 'WP_Plugins_List_Table' );
# <tr class="plugin-update-tr"><td colspan="' . $wp_list_table->get_column_count() . '" class="plugin-update colspanchange">
echo '<tr class="plugin-update-tr" id="' . $this->slug . '-update" data-slug="' . $this->slug . '" data-plugin="' . $this->slug . '/' . $file . '">';
echo '<td colspan="3" class="plugin-update colspanchange">';
echo '<div class="update-message notice inline notice-warning notice-alt">';
$changelog_link = self_admin_url( 'index.php?edd_sl_action=view_plugin_changelog&plugin=' . $this->name . '&slug=' . $this->slug . '&TB_iframe=true&width=772&height=911' );
if ( empty( $version_info->download_link ) ) {
printf(
__( 'There is a new version of %1$s available. %2$sView version %3$s details%4$s.', 'easy-digital-downloads' ),
esc_html( $version_info->name ),
'<a target="_blank" class="thickbox" href="' . esc_url( $changelog_link ) . '">',
esc_html( $version_info->new_version ),
'</a>'
);
} else {
printf(
__( 'There is a new version of %1$s available. %2$sView version %3$s details%4$s or %5$supdate now%6$s.', 'easy-digital-downloads' ),
esc_html( $version_info->name ),

esc_html( $version_info->new_version ),

'<a href="' . esc_url( wp_nonce_url( self_admin_url( 'update.php?action=upgrade-plugin&plugin=' ) . $this->name, 'upgrade-plugin_' . $this->name ) ) .'">',
'</a>'
);
}
do_action( "in_plugin_update_message-{$file}", $plugin, $version_info );
echo '</div></td></tr>';
}
}
