Does the `archiveFilters` tag support secondary or multi-level cascading selection, for example, selecting provinces first and then cities?

As an experienced website operation expert, I am well aware that the filtering function plays a crucial role in content management and user experience.Especially when faced with an overwhelming amount of information, an efficient and intuitive filtering system can greatly enhance the efficiency of users in finding the content they need.AnQiCMS (AnQiCMS) has won a lot of praise in the content operation field with its flexible functions and powerful extensibility.archiveFiltersLabel, take a look at how it performs and implements strategies when dealing with multi-level cascading filtering, such as the need to first select provinces and then cities.

archiveFiltersThe core function of tags: a powerful tool for multi-dimensional filtering

First, let us make it cleararchiveFiltersThe original intention and basic functions of tags. We can clearly see this from the document description of AnQi CMS,archiveFiltersLabels are mainly used to build 'filter conditions that combine list items based on various document parameters'.It provides a convenient way to display various filtering fields defined in the content model on the front-end page.

For example, on a real estate information website, you may want users to be able to filter listings based on "house typearchiveFiltersLabels can present these custom fields defined in the backend content model in a user-friendly manner on the page, allowing users to quickly locate the document list that meets their needs by clicking or selecting.

In particular, when you use it in a templatearchiveFiltersthe tag will output a list containing multiple filtering dimensions (item.Name). Each dimension also has its own multiple optional values (item.Items）。These optional values are not just simple text, each one comes with a filterLinkproperty. When the user clicks on a filter condition, the page will use thisLinkJump or refresh, bring the corresponding filter parameters (such as?housing_type=residential) into the URL to display the filtered content list.

archiveFiltersDirect consideration of cascading filtering

Then, let's go back to the core of our topic:archiveFiltersDoes the tag natively support two-level or multi-level cascading filtering, such as the dynamic联动 effect of first selecting a province and then a city?

To put it bluntly, it is the design scope of the ready-to-use Anqi CMS.archiveFiltersThe tag is inthe design category of its own out-of-the-box design.This does not directly provide the function of multi-level cascading filtering without page refresh. This means that when the user navigates through the page byarchiveFiltersWhen a "province

Why is this happening? The reason is thatarchiveFiltersThe mechanism of the tag. It tends to generatean independent filtering dimension. Each filtering option'sLinkAn attribute, it is always a complete URL, which will guide the browser to send a new request to the server, loading a new page filtered according to all selected parameters.Under this model, each filter is relatively independent and does not update the options of other filters in real time.It is more suitable for handling multiple or parallel filtering conditions rather than relying on the cascade of superior choices in real time.

Implement multi-level cascading filtering strategy: The flexibility and customization of Anqi CMS

AlthougharchiveFiltersThe label does not have a built-in real-time cascade feature, but this is not a limitation of Anqi CMS.On the contrary, thanks to the

To achieve this goal, it can be roughly divided into the following steps:

1. Exquisite design of backend data model:You need to design the hierarchical relationship of your data (such as real estate information) in the Anqi CMS backend content model. For relationships like provinces and cities, you can create two custom fields, such asprovince_id(Province ID) andcity_id(City ID), and ensure they are correctly associated during content entry.Or, you can also consider creating independent content models or configurations for provinces and cities, and storing data through their relationships.

2. JavaScriptization of front-end interaction logic:This is the key to implementing a refreshless cascading filter.You need to write JavaScript code to listen for changes in front-end filters (such as province selection boxes).

   • Get the ID of the selected province.
   • By AJAX (Asynchronous JavaScript and XML) request, send a query to the backend API of Anqi CMS to get the list of cities under the corresponding province.
   • After receiving the city data, dynamically update the city filter box on the page, fill it with new city options, and clear or disable the previous city options until the new data is fully loaded.

3. Backend API support:To enable the front-end JavaScript to retrieve dynamic city data, you need to ensure that the Anqin CMS provides or allows you to develop the corresponding backend API interface.The purpose of this interface is to receive a province ID and then return all the city data under the province.The AnQiCMS is an enterprise-level content management system developed based on the Go language, with a modular design and high concurrency features, providing a solid foundation and convenience for developing such a custom API.Even if there is no out-of-the-box API, it can be easily realized through secondary development.

By using this mode of cooperation between front-end JavaScript and back-end API, you can achieve a smooth and interactive two-level or multi-level cascading filtering experience without refreshing the entire page.archiveFiltersThe tag can still be used to display these filtering conditions, but the data update and option linkage behind it are handled by customized frontend logic and backend API.

In summary, of Anqi CMS'sarchiveFiltersThe tag is an excellent multi-dimensional content filtering tool, it handles parallel filtering needs intuitively.And for those who need more advanced, dynamic two-level or multi-level cascading filter functions, Anqi CMS provides a powerful and flexible platform that allows you to easily implement these complex user experiences by combining its powerful scalability, custom fields, and appropriate frontend and backend development.

Frequently Asked Questions (FAQ)

1. Question:archiveFiltersCan tags apply multiple filter conditions at the same time?Answer: Yes,archiveFiltersLabels are designed to display multiple filtering dimensions.You can use it in parallel in the template to display multiple filter conditions such as house types, house sizes, price ranges, and more.After the user selects these conditions, all selected parameters will be passed through the URL and will act together on the content list filter.

2. Question: How toarchiveFiltersProvide filter data for tags?Answer:archiveFiltersThe filtered data usually comes from the "More Model Custom Fields" defined in the AnQi CMS content model.You can add custom fields such as 'House Type', 'Province' and define optional values for these fields in the content model settings.archiveFiltersThe label will automatically read these configurations and generate the corresponding filter options.

3. Ask: If I only want to implement a simple province-city selection and it's fine to refresh the page each time I select a province, can Anqi CMS directly support this?Answer: If 'refreshing the page' is an acceptable user experience, it will be much simpler to implement. You just need to add custom fields for 'province' and 'city' in the content model, and then use two separatearchiveFiltersLabel to display province and city filters. When the user selects a province, the page refreshes, and the new URL will include the province parameter. At this point, the "city" filter will also display all cities.Although this is not a dynamic cascade, it is also a feasible solution in some scenarios.To filter the city list options more intelligently based on the selected province (even after refreshing the page), make sure that the province information is included in your URL parameters, and the "City" filter generates itsItemsAt that time, it can recognize and display only the cities under the province specified in the URL. This is usually needed during template parsing,archiveFiltersThe backend logic of the label can read and respond to other filtering parameters.
