Add WPML translations to WP2Static v7

Hi @stevygee, thanks for the quick reply. Yes, there is an index.html in that folder.

Hi, @stevygee I implemented your solution, unfortunately it doesn't work for me. In one of the comments you wrote "just create a plugin file with this code and activate the plugin!" Just create a simple wp plugin in the wp-content / plugins directory and activate it? Below I attach some of the code as it is written in my project:

` <?php
/**
* @Wordpress-Plugin
* Plugin Name: Static S3 WPML
* Plugin URI: https://www.xxx.com/
* Description: Additional crawler for wp2static plugin. Crawling pages & subpages translated via WMPL
* Version: 0.0.2
* Author: xxx.com
* Author URI: https://xxx.com/
* Text Domain: static-s3-wpml
*/

function sg_get_translated_posts_urls()
{
    $default_lang = apply_filters('wpml_default_language', null);
    
    $posts = get_posts(array(
        'post_type'        => array('post', 'page'),
        'numberposts'      => -1,
        'suppress_filters' => true,
    ));
    
    $ids = wp_list_pluck($posts, 'ID');
    
    $permalinks = array();
    foreach ($ids as $id) {
        $lang = apply_filters('wpml_post_language_details', null, $id);
        
        if ($lang['language_code'] === $default_lang) {
            continue;
        }
        
        $permalink      = get_permalink($id);
        $wpml_permalink = apply_filters('wpml_permalink', $permalink, $lang['language_code']);
        $wpml_permalink = str_replace(trailingslashit(home_url()), '/', $wpml_permalink);
        $permalinks[]   = $wpml_permalink;
    }
    
    return $permalinks;
}

function sg_add_additional_urls($url_queue)
{
    $translation_urls = sg_get_translated_posts_urls();
    $url_queue        = array_merge($url_queue, $translation_urls);
    
    return $url_queue;
}

add_filter('wp2static_modify_initial_crawl_list', 'sg_add_additional_urls');

I will be grateful for a hint as to what I am doing wrong.
Greetings, Maciek

@jeffceriello So in that case, this gist seems to work, because WP2Static has received the URL and crawled it. Please check the WP2Static output files, open that index.html locally in your browser and check if it contains the contents you expect. If it does, I think you are experiencing an issue with your hosting, unrelated to this gist. If you are getting an error, it means the page has been crawled, but something went wrong during crawling and the error your webserver (running WP) has been saved into the file, in which case it is probably an issue with your webserver config or WP2Static itself.

Ok, I will check that, thanks @stevygee.

@maciejmokrzycki Yes that looks good, should work this way. I just tested again with WP2Static v7.alpha-004 and a snapshot from May 8th and both worked. Please check if you translations show up in the WP2Static logs: WP2Static > Caches > Show URLs/Paths.

Hi, @stevygee

I have noticed some issues

Suppose, I have Contact Page in English and Spanish with Different languages in directories settings in WPML.

Typically, my homepage looks like example.com/ and example.com/es/

Case 1. It works perfectly if I maintain same permalink for all languages.

example.com/contact/ returns 200
example.com/es/contact/ returns 200

All good.

Case 2. Doesn't work with Translated permalinks

example.com/contact/ returns 200
example.com/es/contacto/ returns 404

Issues

1. Crawled logs shows 404 for /es/contact/ which should not be because I have already translated permalink (Ref: case 2)
2. I do not see /es/contacto/ in the crawl logs.
3. However, the actual content of /es/contacto/ appears at /es/contact/ permalink.

This problem presist for Post and Pages.

Expected: I wish to make content appear at translated URL /es/contacto/ which is for Spanish version of Contact page.

Thanks

@thegulshankumar Two things come to mind:

1. Apologize if this is too obvious, but are your translated permalinks working in the WP frontend? So are you getting 200 for /es/contacto/ when accessing WordPress directly? If not, try to get the permalinks working first.
2. Clear your WP2Static Cache before deploying. I found that WP2Static v7 often refuses to crawl a page (even if a change has been made), if it was already cached during a previous deployment process.

Expected: I wish to make content appear at translated URL /es/contacto/ which is for Spanish version of Contact page.

Hi @thegulshankumar

I think this issue can be solved by:
$wpml_permalink = apply_filters( 'wpml_permalink', $permalink, $lang['language_code'] );
→
$wpml_permalink = apply_filters( 'wpml_permalink', $permalink, $lang['language_code'], true );

See $full_resolution parameter at https://wpml.org/wpml-hook/wpml_permalink/.

@stevygee thanks for sharing! I have an idea for improvement.

	$posts = get_posts( array(
		'post_type'        => array( 'post', 'page' ),
		'numberposts'      => -1,
		'suppress_filters' => true, // Get posts in all languages
	) );

	$ids = wp_list_pluck( $posts, 'ID' );

→

	$ids = get_posts( array(
		'fields'           => 'ids',
		'post_type'        => array( 'post', 'page' ),
		'numberposts'      => -1,
		'suppress_filters' => true, // Get posts in all languages
	) );

@fertek You are right, thanks for the simplification!

Edited: After all I was able to get it working using fertek's suggestion above using the true parameter after all. For this to work reliably, you need to go to WPML > Languages > and disable "Adjust IDs for multilingual functionality". Otherwise, the IDs get converted and you will be missing some pages during the crawl.

Thank you for sharing these solutions.

@bkno Glad to hear that it works for you now!
