Make search box placeholder translatable

And here comes another enhacement for this plugin.

Search functionality isn’t WPML compatible. This is an increasing requested feature that follows localization.

To make it compatible we need to transform the URL submission search in this:

eg: http://www.mydomain.com/en/?s=oursearch

WPML plugin became a standard in multilanguage for WordPress, so use their API is wise, nevertheless Polylang is another multilanguage plugin which I use, growing faster in users, that has a WPML compatibility interface.
This is just to justify the type of selection being made when it comes to multilanguage.

To have my responsive menu search box working in a multilanguage environment using Polylang plugin and able to work with WPML as well, I hacked the plugin at /responsive-menu/app/library/responsive-menu/View.php and edited this function as follows:

/**
     * Function to format and display the search bar in the main menu
     *
     * @param  array  $status
     * @return string
     * @added 2.0
     */

    static function searchBar() {

    if (function_exists('icl_get_home_url')) { ?>
        <form action="<?php echo icl_get_home_url(); ?>" id="responsiveSearch" method="get" role="search">
        <?php } else { ?>
        	<form action="<?php echo home_url(); ?>" id="responsiveSearch" method="get" role="search">
        <?php } ?>
            <input type="search" name="s" value="" results=5 autosave=responsive-menu placeholder="<?php echo __('Search', 'responsive-menu'); ?>" id="responsiveSearchInput">
            <input type="submit" style="display: none;" />
        </form>
   <?php
    }

Note that it includes the correction to the search box placeholder translation and the replacement of get_site_url() by home_url()

Sorry, I’ve spoken too soon.

The options from wpml-config.xml, which I’m reproducing here:

<wpml-config>
    <admin-texts>
        <key name="RMOptions">
            <key name="RM" />
            <key name="RMClickTitle" />
            <key name="RMTitle" />
            <key name="RMImage" />
            <key name="RMClickImage" />
        </key>
    </admin-texts>
</wpml-config>

need to be present at wp_otions table, so that the multilanguage plugin can filter them and make them translatable. Looks like you’re using a different aproach and thus those options fields never get extended to receive different values for each language.
Not sure, but it sounds to me they should be registered using:
register_setting( $option_group, $option_name, $sanitize_callback );

That’s great.

Then I guess your plugin has full WPML support now.

My configuration isn’t returning available those options for translation, but it might be related with something else than your plugin which I’ll have to pay atention.
