Adding support for title, id, class to icl_link_to_element

template-functions.php

<?php
// Add this to template-functions.php
// Disclaimer: I based icl_get_anchor_attributes on the _stringify_attributes function on CodeIgniter framework. I made my own function, but I believe this function is just better (and proved to work fine)

function icl_get_anchor_attributes($attributes) {
	if (is_object($attributes) && count($attributes) > 0) {
		$attributes = (array) $attributes;
	}

	if (is_array($attributes)) {
		$atts = '';
		if (count($attributes) === 0) {
			return $atts;
		}
		foreach ($attributes as $key => $val) {
			$atts .= ' '.$key.'="'.$val.'"';
		}
		return rtrim($atts, ',');
	}
	elseif (is_string($attributes) && strlen($attributes) > 0) {
		return ' '.$attributes;
	}
	return $attributes;
}

// Then modify icl_link_to_element function.

// find: function icl_link_to_element($element_id, $element_type='post', $link_text='',
//       $optional_parameters=array(), $anchor='', $echoit = true,
//       $return_original_if_missing = true) {
// replace with:

function icl_link_to_element($element_id, $element_type='post', $link_text='',
        $optional_parameters=array(), $anchor='', $echoit = true,
        $return_original_if_missing = true, $attributes='') {

// find: if (isset($anchor) && $anchor) {
// add after:

if ($attributes !== '') {
    $attributes = icl_get_anchor_attributes($attributes);
}

// Then modify
// find: $link = '<a href="' . $url . '">';
// and change for:

$link = '<a href="' . $url . '" ' . $attributes . '>';

// For using, you only need to send last parameter as an arran, ie:

array("title" => "something")
