Internationalion not working with PHP variable (Wordpress)?

What it basically does is to let the user input text in a field and that text will be displayed in h1 tags. The values is stored in the logo_text PHP variable:

<?php echo get_option(THEME_PREFIX . 'logo_image'); ?>

In order to internationalise it, I tried the following:

<?php echo get_option(__(THEME_PREFIX . 'logo_image') ); ?>

But the string wasn't shown in WPML's string translation panel.

Any suggestions?

header.php:

<h1>
        <?php if (get_option(THEME_PREFIX . "logo_image_enabled")) { ?>
             <img src="<?php bloginfo('template_directory'); ?>/images/<?php echo get_option(THEME_PREFIX . 'logo_image'); ?>" />
        <?php } else { ?>
            <h1><a href="<?php bloginfo('url'); ?>"><?php echo get_option(THEME_PREFIX . "logo_text"); ?></a></h1>
        <?php } ?>
    </h1>

custom-logo.php:

<?php
    $option_fields[] = $logo_image = THEME_PREFIX . "logo_image";
    $option_fields[] = $logo_image_enabled = THEME_PREFIX . "logo_image_enabled";
    $option_fields[] = $logo_text = THEME_PREFIX . "logo_text";

?>

            onSubmit: function(file, ext){
                 if (! (ext && /^(jpg|png|jpeg|gif)$/.test(ext))){
                    // extension is not allowed
                    status.text('Only JPG, PNG or GIF files are allowed');
                    return false;

                } else{

                }

WPML cannot resolve dynamic data inside GetText calls.

Since your 'THEME_PREFIX' doesn't change, all you need to do is translate the 2nd part of the argument and it should work:

• Make sure to replace THEME_TEXTDOMAIN with your theme's textdomain value.
