Question

I have this piece of code in my cms:

<ul class="subsection_tabs" id="tab_group_one" style="clear:none;">
    <?php if ($this->getChildHtml('description')==NULL) { echo '<div id="trollweb_1"></div>'; } else echo('
    <li class="tab"><a href="javascript:void(0);" id="trollweb_1" onClick="trollweb_tabs(1)" class="active"><h4>' . $this->__('Product Description'). '</h4></a></li> '); ?>

The problem is it always outputs the ‘else’. Even though I haven’t filled in the description in the back end and it is blank.

How can I fix this?

Maybe getChildHtml() always returns a string (not NULL). And maybe the string in your test environment only contains whitespaces.
In that case trim() removes them and you can simply check the length of the string

if ( 0<strlen(trim($this->getChildHtml('description'))) ) {
