XF 1.5 Xen:if "has" instead of "equal"

I'm trying to display multiple categories of an addon.
In the database it shows like this:

Some of them have 1 category, some of them have multiple.

How can I show if a "product" is in a category in a template?
If I were to do something like this:

<xen:if is="{$product.category_ids} == 7">
    <a href="#">Indie</a>,
</xen:if>
<xen:if is="{$product.category_ids} == 5">
    <a href="#">Adventure</a>,
</xen:if>
<xen:if is="{$product.category_ids} == 4">
    <a href="#">Action</a>,
</xen:if>

etc, etc for every category with it's respective id and name. Only the first category in the database would show for the product, not multiple if the product had multiple categories.

<xen:if is="in_array(7, {$product.category_ids})">
    <a href="#">Indie</a>,
</xen:if>

<xen:if is="in_array(7, {$product.category_ids})">
    <a href="#">Indie</a>,
</xen:if>

Thanks for the reply @NixFifty ! Although it seems that would be the likely way to do it, doing it this way doesn't display anything.

Ah oops, I mistakenly thought category_ids was an array but it's actually a string.

In your PHP, use something like:

$product['selCategoryIds'] = explode(',', $product['category_ids']);

Pass that to your template and then you can use what I posted above (albeit with a small tweak):

<xen:if is="in_array(7, {$product.selCategoryIds})">
    <a href="#">Indie</a>,
</xen:if>

Sorry for such a long wait to reply. I have been busy busy!

So, everything seems to have worked here. Can see in the sidebar:

Thanks for the help!
However, I have 1 last final question regarding something like this.

in the code here:

<xen:if is="in_array(7, {$product.selCategoryIds})">
    <a href="#">Indie</a>,
</xen:if>

Where it says Indie, if I wanted to display the number there as well, How would I do so?
When pulling data from other items such as the title you simply put {$product.title} in the code and it displays the title. However, for something that has multiple options with commas, how would I go about doing that?
