How to exclude specific category content from the document list?

In website operation, we often need to flexibly control the display of content.For example, you may want to display the latest articles on the homepage, but not include a specific category, such as "Internal Notice" or "Archived Content";Or in a product list, you want to exclude those categories that are 'discontinued' or 'internal testing' to keep the user interface simple and clear.

Safe CMS provides very convenient and powerful features to meet such needs. By skillfully using template tags in thearchiveListWe can easily exclude specific categories of content in the document list, making your website content more accurate and organized.

Precise control: How to exclude specific category content?

Of Security CMSarchiveListThe tag is the core tool we use to call the document list in the template.It is feature-rich and can filter and sort documents based on various conditions.When we want to exclude a specific category from a document list,archiveListThe tag provides a very practical parameter -excludeCategoryId.

This parameter allows you to specify one or more category IDs to remove documents under these categories from the current list.

Actual operation example:

1. Exclude a single category

Assuming your website has a category named "Internal Announcement" with category ID 5. You want to exclude the content of this category from all article lists, then you canarchiveListUse this label:

{% archiveList archives with type="list" limit="10" excludeCategoryId="5" %}
    {% for item in archives %}
        <li>
            <a href="{{item.Link}}">{{item.Title}}</a>
            {# 这里是其他文档信息，例如简介、发布时间等 #}
            <div>{{item.Description}}</div>
            <span>{{stampToDate(item.CreatedTime, "2006-01-02")}}</span>
        </li>
    {% empty %}
        <li>
            该列表没有任何内容
        </li>
    {% endfor %}
{% endarchiveList %}

In this code block,excludeCategoryId="5"Tell the system to ignore articles with category ID 5 when retrieving the list of articles.

2. Exclude multiple categories

If you need to exclude multiple categories, such as the category ID 5 'Internal Announcement' and category ID 8 'Expired Activities', just separate these category IDs with commas:

{% archiveList archives with type="list" limit="10" excludeCategoryId="5,8" %}
    {% for item in archives %}
        <li>
            <a href="{{item.Link}}">{{item.Title}}</a>
            {# 您的文档列表循环代码 #}
        </li>
    {% empty %}
        <li>
            该列表没有任何内容
        </li>
    {% endfor %}
{% endarchiveList %}

By this means, you can flexibly combine the categories that need to be excluded to meet more complex display requirements.

3. Use with other filtering conditions.

excludeCategoryIdThe parameter can be used with otherarchiveListParameters perfectly combined. For example, you may only want to display articles under the 'Product Update' category with ID 10, but at the same time, you want to exclude the content of a subcategory 'Old Version Product' (assuming ID 12):

{# 假设您只想显示分类ID为10的“产品更新”下的文章，但排除其子分类“旧版本产品” (ID 12) #}
{% archiveList archives with type="list" categoryId="10" excludeCategoryId="12" limit="10" %}
    {% for item in archives %}
        <li>
            <a href="{{item.Link}}">{{item.Title}}</a>
            {# 您的文档列表循环代码 #}
        </li>
    {% empty %}
        <li>
            该列表没有任何内容
        </li>
    {% endfor %}
{% endarchiveList %}

Thus, you have achieved the need to further refine and exclude certain subcategories under a specific parent category.
