Problem with "Use of 'self' in callables is deprecated" in WP-Discourse

kendoer · March 1, 2024, 10:22pm

Hello ! I opened WP_DEBUG to test some functions, and see this message:

Deprecated : Use of “self” in callables is deprecated in /wp-content/plugins/wp-discourse/lib/discourse.php on line 225

This message shows in PHP8.2 and 8.3. It’s fine with PHP below&include 8.1.

Is there anything we could do to resolve this? I tend to use PHP8.3 as it shows better performance than 8.1. Thank you very much!

Hello,

No worry; it’s only a deprecation and will be removed in PHP 9 (which is far in the future).
You still can use PHP 8.3.

          		$discourse_url = ! empty( $this->options['url'] ) ? $this->options['url'] : null;
          		$domain_name   = wp_parse_url( $discourse_url, PHP_URL_HOST );
          		update_option( 'wpdc_discourse_domain', $domain_name );
          		update_option( 'discourse_option_groups', $this->discourse_option_groups );
          
          		foreach ( $this->discourse_option_groups as $group_name ) {
          			if ( 'discourse_configurable_text' === $group_name && get_option( 'discourse_configurable_text' ) ) {
          				$saved_values   = get_option( 'discourse_configurable_text' );
          				$default_values = $this->discourse_configurable_text;
          				$merged_values  = array_merge( $default_values, $saved_values );
          				array_walk( $merged_values, 'self::register_text_translations' );
          				update_option( $group_name, $merged_values );
          			} else {
          				add_option( $group_name, $this->$group_name );
          			}
          		}
          
          		// Transfer 'use-discourse-comments' and 'add-join-link' options. Plugin version 1.7.7.
          		$commenting_options = get_option( 'discourse_comment' );
          		if ( ! empty( $commenting_options['use-discourse-comments'] ) || ! empty( $commenting_options['add-join-link'] ) ) {
          			$commenting_options['enable-discourse-comments'] = 1;

I believe this should be used now: self::class . 'register_text_translations'

Just to share that someone made a PR a few months ago to fix this:
