How to Create a Custom WordPress Search Form (Step by Step)
The default WordPress search leaves a lot to be desired. Out of the box, it only searches post and page titles and content, often returning poor results. And the search form itself is very basic, with no options to filter or refine results.
The good news is that with a bit of know-how, you can dramatically improve your WordPress site‘s search experience. Creating a custom search form gives you full control over what gets searched, how results are ranked and displayed, and the overall search interface.
In this in-depth guide, we‘ll walk through how to create a custom WordPress search form step by step. Whether you‘re comfortable with code or prefer to use plugins, you‘ll learn how to build a powerful, user-friendly search tailored to your site. Let‘s get started!
Why Create a Custom Search Form in WordPress
The default WordPress search is very limited:
- It only searches post and page title and body content, ignoring custom fields, taxonomies, and other metadata.
- There‘s no way for users to filter or narrow results by category, tag, author, date, or other criteria.
- The search algorithm is very basic, often returning less relevant results.
- The search form itself can‘t be easily customized or styled to fit your theme.
All of this adds up to a subpar user experience, especially on large sites. Visitors often struggle to find what they‘re looking for and get frustrated.
Creating a custom WordPress search form solves these issues:
- You can choose exactly what content is searchable, including custom post types, fields, taxonomies, and more.
- You can provide filters and advanced search options to help users refine results.
- You have full control over the search algorithm and how results are ranked/scored for relevance.
- You can style the search form and results to perfectly match your site design.
The end result is a much more effective, user-friendly search experience. Visitors are able to quickly find the content they need, without frustration. This boosts engagement, reduces bounces, and ultimately helps drive more conversions.
Planning Your Custom Search Form
Before diving into implementation, it‘s important to plan out your custom search form. Think through questions like:
- What content do I want to make searchable? Besides posts and pages, consider custom post types, taxonomies, fields, and more.
- What filters and options will I provide? Common ones include category, tag, author, and date, but the possibilities are endless.
- How will I style the form and results to fit my design? Consider colors, fonts, layout, etc.
The answers will depend a lot on the specifics of your site. An ecommerce store has very different search needs than a blog or news site.
For example, let‘s say you run a job board with custom post types for job listings. You‘d want to make those listings searchable, perhaps with filters for job category, type (full-time, part-time, etc.), and location. The search form should be prominently placed and styled to fit the look of your site.
On the other hand, a food blog may just need a simple recipe search. The form could be a basic input with filters for meal type, cuisine, or dietary restrictions. The styling could be more subtle to blend in with your theme.
The planning process is all about aligning your search functionality with your users‘ needs and your site‘s content. Taking the time to think it through upfront will make the actual implementation much smoother.
Coding a Custom Search Form Template
The most powerful and flexible way to create a custom search form is by directly editing your theme template files. This gives you complete control over the markup, styling, and functionality.
To get started, you‘ll need to create a new template file called searchform.php in your theme directory. This is the file WordPress looks for when outputting the search form.
Here‘s a basic example of what this file might look like:
<form role="search" method="get" class="search-form" action="<?php echo esc_url( home_url( ‘/‘ ) ); ?>">
<label for="search">Search for:</label>
<input type="search" id="search" name="s" value="<?php echo get_search_query(); ?>" />
<button type="submit">Search</button>
</form>This outputs a simple search form with a label, input, and submit button. The get_search_query() function fills in the input with the current search query, if any.
To add filters and advanced options, you can use additional inputs and the WP_Query parameters. For example, to add a category dropdown:
<select name="category">
<option value="">All categories</option>
<?php
$categories = get_categories();
foreach ( $categories as $category ) {
$selected = ( $_GET[‘category‘] == $category->slug ) ? ‘selected‘ : ‘‘;
echo ‘<option value="‘ . $category->slug . ‘" ‘ . $selected . ‘>‘ . $category->name . ‘</option>‘;
}
?>
</select>This loops through all the categories and outputs them as <option> tags. It also checks the URL parameters to keep the dropdown in sync with the current search.
You can add taxonomies, post types, custom fields, and more using a similar approach. Just be sure to update your search query to take them into account (more on that below).
Once your form markup is in place, you can style it to match your theme. Use CSS to control the layout, colors, fonts, and other visual styles.
Finally, you‘ll need to edit your search results template (search.php) to display the results from your custom form. Use the WP_Query parameters to modify the main query based on the selected filters:
$args = array(
‘s‘ => get_search_query(),
‘category‘ => $_GET[‘category‘],
‘post_type‘ => ‘post‘,
);
$search_query = new WP_Query( $args );This takes into account the search query (s) and selected category. You can add more parameters to further customize the results.
Using Plugins to Create Custom Search Forms
If you‘re not comfortable editing theme files directly, you can use a plugin to create custom search forms. There are a number of great options available:
- SearchWP is a powerful plugin that lets you create custom search engines for your site. It indexes all your content (including custom fields and taxonomies) and provides a drag-and-drop form builder to easily customize your search interface. It also has options to weight certain fields higher, customize the algorithm, and more.
- Relevanssi replaces the default WordPress search with a more relevant, flexible solution. It lets you define what gets indexed (including custom fields, shortcodes, and more) and adjust the weighting of different fields. It also has built-in support for multi-language sites, fuzzy matching, and other advanced features.
- Advanced Custom Fields is a popular plugin for adding custom fields to WordPress. While not strictly a search plugin, it does have an option to make custom fields searchable. This works great if you just need to add a few extra fields to your search, without all the complexity of a standalone search plugin.
Using a plugin can be a good middle ground between the simplicity of the default search and the flexibility of a fully custom solution. You get more power and customization, without having to touch any code.
For example, with SearchWP, you can create a custom search form with just a few clicks:
- Install and activate the SearchWP plugin
- Go to the SearchWP settings page and create a new search engine
- Choose what post types, taxonomies, and fields to include
- Customize the weighting and relevance settings to fine-tune the results
- Use the Form Builder to create your custom search form
- Paste the form shortcode anywhere you want it to appear
That‘s it! You now have a fully custom search form up and running. You can further customize the form and results using the plugin settings and your own CSS.
Enhancing Your Custom Search Form
Once you have a basic custom search form in place, there are a few ways you can enhance it to provide an even better experience:
- Add live search (aka "instant search" or "search as you type"). This uses AJAX to display search results instantly as the user types, without reloading the page. SearchWP and other plugins have built-in support for this. You can also implement it yourself with some custom JavaScript.
- Highlight the search terms in the results. This makes it easy for users to see why a particular result matched their query. SearchWP and Relevannsi both offer this feature out of the box. You can also do it yourself by wrapping the terms in
<mark>tags before outputting the results. - Track searches and use the data to improve your content. Knowing what users are searching for (and not finding) can give you valuable insights into how to optimize your site. Most search plugins keep track of queries in the WordPress dashboard. You can also use a tool like Google Analytics to track site search and see how it affects user behavior.
These enhancements can take your custom search form from good to great. They provide a faster, more intuitive, and more helpful search experience for your visitors.
Custom Search Form Examples and Use Cases
To spark your creativity, here are a few examples of effective custom search forms for different types of sites:
WooCommerce Product Search
The default WooCommerce search only looks at product titles and descriptions. By creating a custom form, you can search SKUs, categories, tags, attributes, variation data, and more.
Some features to consider:
- Filters for category, price range, brand, size, color, etc.
- Options to sort by relevance, price, popularity, rating, etc.
- Instant search results with product images and prices
- Advanced search textbox with autocomplete suggestions
Real Estate Listings Search
If you‘re using WordPress to power a real estate website, a custom search form is essential. Visitors expect to be able to search by location, price, property type, number of bedrooms/bathrooms, square footage, amenities, and more.
Some features to consider:
- Textbox for keywords/MLS number
- Dropdown for property type (single-family, condo, land, etc.)
- Sliders for price and square footage ranges
- Checkboxes for must-have amenities (pool, garage, etc.)
- Map-based search to show only listings in a selected area
Knowledge Base Search
A knowledge base or documentation site needs a powerful search to help users find answers fast. In addition to article titles and body content, you may want to search comments, tags, custom fields, and attachments.
Some features to consider:
- Filters for topic, product, or section
- Options to search just titles or full text
- Instant search with article excerpts and URLs
- Weighted results that favor certain sections or terms
- Synonym detection to match related terms
Of course, these are just a few examples. The possibilities for custom search forms are endless! The key is to tailor the functionality and design to your particular use case and audience.
