Can someone please help me with displaying links related to selected attributes please?

I have a custom select attribute witk multiple values selected.
I need to display a different url based on the selected attribute.

This is what i have now in my code:

$materiaal = $c->getCollectionAttributeValue('project_materiaal'); //Custom Selection attribute

$selectedOptions = $c->getCollectionAttributeValue('project_materiaal');
if($selectedOptions == "leisteen"){
$materiaalUrl = "/leidekkers";
}
else {
$materiaalUrl = "/metalen";
}

But this is not working, all url's are getting displayed as '/metalen' now, so the first part of this code gets skipped.
I guess i need to do something with 'foreach', but i'm not a real coder so i don't know how i can fix this.

Some help from a real coder will be highly appreciated!

Have a look at my free quick attributes block. As a diagnostic on the page it may help you debug and also contains some code examples.

You may also find this howto of use:

If your select attribute is a multi-select, it will be returning an array, so you have to look for your comparison within the array using php in_array().

Or for a way to do stuff like this with no php coding - use my Magic Data addon.

You are not accessing the value of the select attribute properly. Because a select attribute could have more than one selection, you need to loop through the selections and check their "value" property. For example:
$materiaals = $c->getCollectionAttributeValue('project_materiaal');
$ist_leisteen = false;
foreach ($materiaals as $materiaal) {
    if ($materiaal->value == 'leisteen') {
        $ist_leisteen = true;
        break;
    }
}
if ($ist_leisteen) {
    $materiaalUrl = '/leidekkers';
} else {
    $materiaalUrl = '/metalen';
}



And for more details than you ever probably want to know about "related links" and select attributes, see the following threads:

Also note that there's an addon in the marketplace that does "related links" -- I'm not sure if it is right for your situation, but if you're rather pay some money than spend the time coding it yourself, it might be worth looking into:
