Enhance Your WordPress Form with Custom Post Type Search

When developing a WordPress site, sometimes you may find that your form dropdowns can get overcrowded with options, especially when pulling data from custom post types. This is a common issue faced by many developers, particularly when they need to present users with a long list of companies to choose from. In this guide, we will address how to transform a simple dropdown menu into a more user-friendly search feature, allowing users to type in text and filter the results dynamically.

The Challenge

Suppose you have a form with a dropdown that lists all companies pulled from your custom post types. The initial implementation might look something like this:

While functional, this dropdown can become cumbersome as the list of companies grows long. To improve usability, you want to allow users to start typing the company name and see results filtered in real-time.

The Solution

To achieve this enhanced functionality, we will switch from a traditional dropdown to an input field coupled with the datalist HTML element. This allows us to provide suggestions based on what the user types, improving the overall user experience.

Step-by-Step Implementation

1. Replace the Dropdown with an Input Field

Start by modifying your existing code to include an input field that references a datalist. Here’s how this can look:

2. Explanation of the Code

Querying Custom Post Types: We initialize a WP_Query to fetch all published posts of type 'companies'. This step ensures we have access to all relevant companies.

Input Field: The input element with the ID company is linked to the datalist by using the list attribute. This tells the browser that suggestions will come from the specified datalist.

Datalist Options: Within the datalist, we loop through each company obtained from the query and create an option tag for each. The value attribute is set to the company's title, making it available for display as users type.

3. Advantages of Using Datalist

The datalist element provides several benefits:

User-Friendly: As users type, relevant options appear, enabling quicker selection.

Cleaner Interface: Offers a cleaner look without long dropdown lists cluttering the interface.

Change Over Time: Easily adapt to varying amounts of data without altering the backend codebase.

Conclusion

By implementing an input field with a datalist, you can significantly enhance the user experience in your WordPress forms that involve selecting from custom post types. This solution not only simplifies the selection process but also makes your forms look modern and efficient.
