Table Availability Filters: Building Dynamic Filters with Porto Theme’s AJAX Features

In the restaurant business, timing is everything. Customers browsing your website aren’t just looking for a menu. They want to know if they can get a table when they want one. A slow or outdated booking system can turn that curiosity into frustration, and frustration into lost revenue. That’s where dynamic table availability filters come in. With the right setup, your guests can easily search by date, time, or group size and instantly see what’s available.

The Porto Theme offers powerful AJAX filtering tools that help restaurant websites become faster, more responsive, and far more useful. This technology lets your website update its content without refreshing the whole page, creating a seamless experience for visitors. Whether you’re running a cozy bistro or managing several dining rooms across town, using Porto’s AJAX filters can help you deliver faster answers and smoother bookings. In this article, we’ll walk through how to plan, build, and fine-tune your restaurant tables and their availability filters using the tools built into the Porto Theme.

Getting to Know AJAX and Porto

To start, let’s look at what AJAX does. In simple terms, AJAX allows a webpage to update parts of its content without reloading the entire page. This means users can select a time slot or a group size and instantly see the updated availability, no spinning wheel, no waiting.

The Porto Theme includes robust support for AJAX out of the box. It was designed to be flexible, responsive, and modern, making it a solid choice for restaurants and hospitality businesses. The theme also integrates well with WooCommerce, which opens up even more options if your website handles online orders, gift cards, or event reservations. That built-in compatibility gives you room to grow, without needing to start over.

Start with a Smart Plan

Before jumping into the technical side of things, take time to plan your filters. Think about what your customers need to search for. A few useful filter categories might include:

• Date of reservation
• Time of day
• Number of guests
• Table type (indoor, outdoor, booth, bar seating)
• Location, if you run multiple restaurants or rooms

It’s also helpful to align your filters with the physical layout of your space. Do you want people to see only outdoor tables after a certain time? Should booths be hidden when they’re reserved for groups only? These decisions help you build filters that make sense to your guests.

On the technical side, your filters will need to connect with your reservation data and your table inventory. That connection needs to be well-structured from the beginning. If done right, you’ll avoid issues like filters showing unavailable tables or offering confusing choices.

Set Up the Data Behind the Filters

Once your filters are mapped out, it’s time to build the data that powers them. This means creating custom post types for your tables or reservation slots. You’ll also want to use meta fields to store information like:

• Table size (2-person, 4-person, etc.)
• Availability status
• Seating type (high-top, patio, etc.)
• Location or zone within your restaurant

Tools like Advanced Custom Fields (ACF) make this process easier, especially if you don’t want to write code. Storing this data in a clean, structured format will ensure your filters can pull the right information and show it instantly.

When your data is organized well, AJAX filters work more efficiently, and your website remains quick and responsive.

Build Your Filters with Porto’s AJAX Features

With your data in place, it’s time to create the filters themselves. Porto’s built-in widgets and filter blocks make it easy to set up dynamic filtering. You can design filter bars that respond in real time, and when a customer chooses a time slot or number of guests, the results update instantly without reloading.

This dynamic behavior isn’t just about speed. It makes the whole experience feel modern and intuitive. Customers stay engaged, which increases the chance they’ll complete their booking.

Once you’ve set things up, take time to test how well the filters connect with your custom post types. Make sure availability updates correctly and the filters don’t display empty results unless necessary.

Design for Simplicity and Speed

Good design helps filters work better. You’ll want to choose the right filter controls, like dropdown menus for time slots, sliders for group size, or checkboxes for seating type. These should be easy to understand and fast to use.

The Porto Theme lets you apply your styling, so filters can match your brand colors and overall website look. A clean, mobile-friendly layout goes a long way, especially since many diners book tables from their phones.

Keep the interface uncluttered. Consider features like sticky filters that stay visible while users scroll. Offer smart default values, like today’s date or the most popular time slot, to reduce the effort needed to get started.

Keep Things Running Fast

AJAX is powerful, but it needs a little care to run smoothly. Filtering too much data at once can slow things down. One good practice is to use lazy loading or pagination when your inventory is large. This keeps the site moving quickly, even during peak traffic.

Another key is using a good caching strategy. Porto works well with caching plugins like WP Rocket or W3 Total Cache. If your site relies heavily on live updates, look into conditional caching to avoid outdated content.

Careful testing will help you spot performance bottlenecks. If filters seem sluggish, check how many database calls are being made and streamline wherever you can.

Connect Filters with Your Booking System

Filters are useful on their own, but they shine when integrated with a booking system. Plugins like Amelia or WP Simple Booking System work well with Porto. They allow you to show live availability, block out already-reserved tables, and confirm bookings automatically.

You can also prevent double-bookings using conditional logic. For example, when one guest books a 6 PM patio table, that table disappears from search results for everyone else. Look for systems that also send confirmation emails, allow calendar syncing, and notify staff in real time.

From Filters to Full Tables

Making it easier for guests to find and book available tables improves the entire dining experience before they even walk through the door. By using the Porto Theme’s AJAX filtering features, restaurant owners can offer faster searches, real-time results, and smooth booking flows. That means fewer lost opportunities, more full seats, and a better impression from the first click.

These filters are not hard to set up when you break the process into thoughtful steps. With a clear plan, structured data, and smart styling, you can make your website as welcoming and efficient as your front of house. And once your guests get a taste of how easy it is to find a seat, they’ll keep coming back, not just for the food, but for the convenience.
