ste_yeu on "Polylang doesn't show all the strings from wpml-config.xml"

I lost a lot of time for this problem, there were two alteatives to resolve it:

1. Using the shortcodes [polylang]:

// [polylang lang="en"]English[/polylang][polylang lang="sp"]Spanish[/polylang]
function polylang_shortcode($atts, $content = null)
{
        if (empty($content))
                retu '';
        extract( shortcode_atts( array('lang' => ''), $atts ) );
        if (empty($lang))
                retu "<h3>You must specify 'lang' using shortcode: polylang</h3>";

        retu ($lang == pll_current_language()) ? $content : '';
}
add_shortcode('polylang', 'polylang_shortcode');

This trick saved me many times, I think that the developers should integrate it.

Unfortunately in many fields of this theme I can't use shortcodes, so I could not use this trick.

2. Using php code, and I resolved in this way, so I had to edit the php file of theme section:

<?php

                $url = 'http://' . $_SERVER['SERVER_NAME'] . $_SERVER['REQUEST_URI']; // get current url

                if (false !== strpos($url,'/en/')) { // if in url I find the string /en/
                        echo 'eng';
                } elseif (false !== strpos($url,'/it/')) { // if in url I find the string /it/
                                echo 'ita';
                        }
        ?>
