Code Overview

Registering Custom Post Type

The plugin registers a custom post type for travel packages:

function travel_packages_custom_post_type() {
    $labels = array(
        'name'               => __( 'Travel Packages', 'travel-packages-plugin' ),
        'singular_name'      => __( 'Travel Package', 'travel-packages-plugin' ),
        'menu_name'          => __( 'Travel Packages', 'travel-packages-plugin' ),
        'name_admin_bar'     => __( 'Travel Package', 'travel-packages-plugin' ),
        'add_new'            => __( 'Add New', 'travel-packages-plugin' ),
        'add_new_item'       => __( 'Add New Travel Package', 'travel-packages-plugin' ),
        'new_item'           => __( 'New Travel Package', 'travel-packages-plugin' ),
        'edit_item'          => __( 'Edit Travel Package', 'travel-packages-plugin' ),
        'view_item'          => __( 'View Travel Package', 'travel-packages-plugin' ),
        'all_items'          => __( 'All Travel Packages', 'travel-packages-plugin' ),
        'search_items'       => __( 'Search Travel Packages', 'travel-packages-plugin' ),
        'parent_item_colon'  => __( 'Parent Travel Packages:', 'travel-packages-plugin' ),
        'not_found'          => __( 'No travel packages found.', 'travel-packages-plugin' ),
        'not_found_in_trash' => __( 'No travel packages found in Trash.', 'travel-packages-plugin' )
    );

    $args = array(
        'labels'             => $labels,
        'public'             => true,
        'publicly_queryable' => true,
        'show_ui'            => true,
        'show_in_menu'       => true,
        'query_var'          => true,
        'rewrite'            => array( 'slug' => 'travel-package' ),
        'capability_type'    => 'post',
        'has_archive'        => true,
        'hierarchical'       => false,
        'menu_position'      => null,
        'supports'           => array( 'title', 'editor', 'thumbnail', 'custom-fields' ),
        'register_meta_box_cb' => 'add_travel_package_meta_boxes'
    );

    register_post_type( 'travel-package', $args );
}
add_action( 'init', 'travel_packages_custom_post_type' );

Adding Meta Boxes

The plugin adds meta boxes for additional travel package details:

function add_travel_package_meta_boxes() {
    add_meta_box(
        'travel-package-details',
        __( 'Travel Package Details', 'travel-packages-plugin' ),
        'render_travel_package_details_meta_box',
        'travel-package',
        'normal',
        'high'
    );
}

Rendering Meta Boxes

The plugin renders the meta boxes for user input:

function render_travel_package_details_meta_box( $post ) {
    $country = get_post_meta( $post->ID, 'country', true );
    $cost = get_post_meta( $post->ID, 'cost', true );
    $duration = get_post_meta( $post->ID, 'duration', true );
    $map_url = get_post_meta( $post->ID, 'map_url', true );
    $package_includes = get_post_meta( $post->ID, 'package_includes', true );
    $package_excludes = get_post_meta( $post->ID, 'package_excludes', true );
    $photos = get_post_meta( $post->ID, 'photos', true );

    // Render HTML form fields here...
}

Saving Meta Box Data

The plugin saves the meta box data when the travel package is saved:

function save_travel_package_details( $post_id ) {
    if ( defined( 'DOING_AUTOSAVE' ) && DOING_AUTOSAVE ) {
        return;
    }

    if ( isset( $_POST['country'] ) ) {
        update_post_meta( $post_id, 'country', sanitize_text_field( $_POST['country'] ) );
    }

    if ( isset( $_POST['cost'] ) ) {
        update_post_meta( $post_id, 'cost', sanitize_text_field( $_POST['cost'] ) );
    }

    if ( isset( $_POST['duration'] ) ) {
        update_post_meta( $post_id, 'duration', sanitize_text_field( $_POST['duration'] ) );
    }

    if ( isset( $_POST['map_url'] ) ) {
        update_post_meta( $post_id, 'map_url', sanitize_text_field( $_POST['map_url'] ) );
    }

    if ( isset( $_POST['package_includes'] ) ) {
        update_post_meta( $post_id, 'package_includes', wp_kses_post( $_POST['package_includes'] ) );
    }

    if ( isset( $_POST['package_excludes'] ) ) {
        update_post_meta( $post_id, 'package_excludes', wp_kses_post( $_POST['package_excludes'] ) );
    }

    if ( isset( $_FILES['photos'] ) ) {
        $photo_urls = array();

        $photo_files = $_FILES['photos'];

        foreach ( $photo_files['name'] as $key => $photo_name ) {
            $photo_tmp = $photo_files['tmp_name'][$key];
            $photo_type = $photo_files['type'][$key];
            $upload_dir = wp_upload_dir();
            $upload_path = $upload_dir['path'];
            $upload_url = $upload_dir['url'];

            $photo_path = $upload_path . '/' . $photo_name;
            $photo_url = $upload_url . '/' . $photo_name;

            move_uploaded_file( $photo_tmp, $photo_path );

            $photo_urls[] = $photo_url;
        }

        update_post_meta( $post_id, 'photos', $photo_urls );
    }
}
add_action( 'save_post_travel-package', 'save_travel_package_details' );

Displaying the Travel Package

The plugin provides a template for displaying travel packages:

function display_travel_package($content) {
    if ( 'travel-package' == get_post_type() ) {
        $country = get_post_meta( get_the_ID(), 'country', true );
        $cost = get_post_meta( get_the_ID(), 'cost', true );
        $duration = get_post_meta( get_the_ID(), 'duration', true );
        $map_url = get_post_meta( get_the_ID(), 'map_url', true );
        $package_includes = get_post_meta( get_the_ID(), 'package_includes', true );
        $package_excludes = get_post_meta( get_the_ID(), 'package_excludes', true );
        $photos = get_post_meta( get_the_ID(), 'photos', true );

        // Display the travel package details here...
    }

    return $content;
}
add_filter('the_content', 'display_travel_package');
