Avoid duplicate entries tagged with multiple categories

Question

Let's say I have entries tagged with multiples categories, for example category_id="1" and category_id="2".

Then when I do:

{exp:channel:entries channel="news" category="1" orderby="date" status="open"}
    {categories}
    <span>{category_id}</span>
    <h5><a href="{site_url}news/category/{category_url_title}/{url_title}">{title}</a></h5>
    {/categories}
{/exp:channel:entries}

I get the following result:

1
My entry title
2
My entry title
1
Another entry
2
Another entry

Why is that? How can I avoid this? If I ask specifically for category_id="1" in my {exp:channel:entries} parameter, I should get only entries belonging to said category.

Thanks in advance for your help.

Looks like your code is a bit strange here, specifically the {categories}{/categories} tag pair wrapping everything.

Could you try the following and see if it works ?

{exp:channel:entries channel="news" category="1" orderby="date" status="open"}

    <h5>{title} - {categories}{category_id}{/categories}</h5>

{/exp:channel:entries}

If that works, then that's the problem.

Going back to your original code, I see another problem you are going to face if you structure your URLs like this: if an entry belongs to more than one category, you are going to have a problem constructing your URLs as you are doing here. If you can, working with url segments is probably a safer route here.
