I'm using this kind of statements on other places in the webshop (product detail page) but I want to use this one is on the category page:
<?php if ($_product->getAttributeText('cp_doos_specificaties') == "Ja" || "Yes"): ?> But for some reason this isn't working... When I remove the || Yes it's working, but I need the Yes also because the webshop is also in English and otherwise the code won't work.
Hope someone can help me with this.
Yo can use like below statement in your case,
This condition is allow both value Ja And Yes
<?php if ($_product->getAttributeText('cp_doos_specificaties') == "Ja" || $_product->getAttributeText('cp_doos_specificaties') == "Yes"): ?> In addition to Rakesh Jesadiya who is absolutely correct in his answer, I think you should also improve the quality of the IF-statement.
If the attribute cp_doos_specificaties is a Yes/No-attribute, it will either have values "0" (for no) or "1" (for yes). Your IF-statement only takes into account 2 languages, and if someone ever adds another, they will have to know this - which is very unlikely to happen.
Instead, better use this:
<?php // language-independent check if ($_product->getData('cp_doos_specificaties') == "1") { // ... } 
Zend_Debug::dump($_product->debug());, you can see the data available in the place where you are. <?php if ($_product->getData('cp_doos_specificaties') == "1"): ?> I think Your flat tables is enable so Follow below steps,
cp_doos_specificaties in attribute codeyes to Used in Product ListingSystem->index ManagmentDepending on your attribute type, you can use $_product->getAttributeText('xyz') or $_product->getData('xyz') to get attribute value.
Instead of
<?php if ($_product->getAttributeText('cp_doos_specificaties') == "Ja" || $_product->getAttributeText('cp_doos_specificaties') == "Yes"): ?> you should consider to make this work language independend. It seems better to compare the attributes to the translated value.
if ($_product->getAttributeText('cp_doos_specificaties') == $this->__('Yes')) Now make shure "Yes" is somewhere translated in one of your translation.csv.
If the attribute only returns 0 or 1, you can use
if ($_product->getData('cp_doos_specificaties'))
