Alternative layout with moduleclass_suffix

Question

I have a Problem with the carousel module from bootstrapjoomla.com Unfortunately the module doesn't support alternative layouts. But I need to have two carousel on my homepage. Therefore I've to create an override for the carousel where I change the carousel-id.

I tried to create an html-override depending on the moduleclass suffix but it doesn't work. The moduleclass suffix of my second carousel is " Carousel-carousel2". The code I inserted in the default.php in the override:

<?php
defined('_JEXEC') or die;
/* Layout anhand einer CSS-Klasse im Modul umleiten */

if(preg_match('/\Carousel-([A-Za-z]+)/', $module->moduleclass_sfx , $matches)){
 if(!empty($matches[1])){
  $this->setLayout($matches[1]);#ist Layout carousel2
   echo $this->loadTemplate('default'); #carousel2_default.php wird aufgerufen
  }
}else{ 

... 

} ?> 

carousel2_default.php is the file with my override.

My problem is, that the second carousel doesn't use the override but uses the default.php.

You can easily add the advanced module options that allow alternative layouts, by creating an override of the modules .xml and adding the advanced fields options within the <fields name="params"> tags, like this:

<config>
    <fields name="params">
        <fieldset name="advanced">
            <field
                name="layout"
                type="modulelayout"
                label="JFIELD_ALT_LAYOUT_LABEL"
                description="JFIELD_ALT_MODULE_LAYOUT_DESC" />
            <field
                name="moduleclass_sfx"
                type="text"
                label="COM_MODULES_FIELD_MODULECLASS_SFX_LABEL"
                description="COM_MODULES_FIELD_MODULECLASS_SFX_DESC" />
            </fieldset>
    </fields>
</config>

This adds the options for alternative layouts and custom module class suffix to the module settings, under the advanced tab, so you can select your alternative layout.
