How I Built a Custom travel agency Website Using WordPress & PHP — A Technical Breakdown
A technical, non-promotional walkthrough focused on architecture, code, and lessons learned.
Why I Chose WordPress + PHP
Before starting development I evaluated multiple approaches: SaaS builders, static sites with booking widgets, and a custom backend (Laravel/Node). I chose WordPress + PHP for these reasons:
- Full control over code and extensibility.
- Non-technical team can manage content easily.
- Large plugin ecosystem for travel-related features.
- Cost-effective hosting and fast iteration.
Project Requirements
- Custom Tour Package Management — structured fields: price, itinerary, gallery, inclusions/exclusions.
- Blog System for travel guides and SEO content.
- Lead forms (enquiry and custom requests) with server-side validation.
- Performance — image-heavy pages must remain fast.
- SEO — clean slugs, schema, sitemaps.
Stack & Architecture
Key choices I made:
- WordPress (latest stable) with a lightweight parent theme and a child theme for customisation.
- PHP 8.x, Nginx, FastCGI caching, and Cloudflare CDN.
- Plugins used selectively: ACF, Yoast SEO, WP Super Cache, Smush. I avoided plugin sprawl.
Custom Post Type: tour_packages
I created a Custom Post Type to manage tour packages. Here is the snippet I used in functions.php:
function create_tour_package_cpt() {
$labels = array(
'name' => 'Tour Packages',
'singular_name' => 'Tour Package'
);
$args = array(
'labels' => $labels,
'public' => true,
'menu_icon' => 'dashicons-airplane',
'supports' => array('title','editor','thumbnail'),
'rewrite' => array('slug' => 'package')
);
register_post_type('tour_packages', $args);
}
add_action('init','create_tour_package_cpt');<p>This gives editors an easy UI while keeping content structured for templates and listing pages.</p>
ACF: Structured Fields
I used Advanced Custom Fields (ACF) for fields such as duration, price, itinerary (repeater), and gallery. Example output in single-tour_packages.php:
<?php if( get_field('duration') ): ?>
<p><strong>Duration:</strong> <?php the_field('duration'); ?></p>
<?php endif; ?>
<?php if( get_field('price') ): ?>
<p><strong>Starting Price:</strong> <?php the_field('price'); ?></p>
<?php endif; ?>Enquiry Form: Lightweight PHP Handler
To minimise plugin overhead, I implemented a small PHP form handler with sanitisation and wp_mail. HTML form:
<form method="POST" action="">
<input type="text" name="name" placeholder="Your Name" required>
<input type="email" name="email" placeholder="Your Email" required>
<textarea name="message" required></textarea>
<button type="submit">Submit</button>
</form><p>PHP handler example (placed in <code>functions.php</code>):</p>
<pre><code class="language-php">function handle_enquiry_form() {
if ( isset($_POST['name']) ) {
$name = sanitize_text_field($_POST['name']);
$email = sanitize_email($_POST['email']);
$message = sanitize_textarea_field($_POST['message']);
wp_mail(
'agency@example.com',
'New Enquiry From Website',
"Name: $name\nEmail: $email\nMessage: $message"
);
}
}
add_action('init', 'handle_enquiry_form');
Performance Optimisations
Because travel pages typically contain many photos, I applied the following:
- Serve WebP when supported and fall back to JPEG/PNG.
- Lazy-load below-the-fold images.
- Use Cloudflare CDN and Nginx FastCGI caching for public pages.
- Image compression and a simple asset pipeline for CSS/JS.
Tip: balance beautiful visuals with practical file sizes. Large hero images look great but harm mobile load times.
SEO & Structured Data
I used Yoast for metadata and added JSON-LD for LocalBusiness/TravelBusiness where appropriate. Example minimal JSON-LD snippet:
{
"@context": "https://schema.org",
"@type": "TravelAgency",
"name": "Ruuraa Holidays",
"url": "https://www.ruuraaholidays.com/"
}<p>Additionally, I ensured clean slugs like <code>/package/kuala-lumpur-tour/</code>, and submitted a sitemap to Search Console.</p>
Challenges
- Parent theme conflicts — resolved by overriding templates in the child theme.
- ACF repeater performance — limited repeater depth and paginated long itineraries on the frontend.
- Design vs performance — iterated homepage design to reduce render-blocking assets.
Lessons Learned
- Selective plugins + small custom PHP components keep the backend maintainable.
- Custom post types are valuable for business content—structure beats mixing everything into posts.
- Performance tuning early saves future redesign costs.
Conclusion
WordPress with targeted PHP customisations provides a flexible and maintainable platform for business websites. For a travel business, the combination of structured content (CPT + ACF), careful performance optimisations, and clear SEO practices creates a workhorse site that editors can manage without developer intervention.
