Hooks & template overrides

Specifico gives developers two ways to customize the specification table: hooks (filters and actions) for targeted tweaks without touching markup, and a template override for full control of the HTML.

Hooks

Hooks come in two groups. Data hooks run before the table renders, so they apply everywhere — including the [specifico] shortcode — and keep working even if you override the template. Presentation hooks live inside the template, so they run unless you've replaced it (in which case you copy them across with the rest of the markup).

Data hooks

specifico_tab_title (filter)

Rename the Specifications tab. Receives the title and the WC_Product.

add_filter( 'specifico_tab_title', function ( $title, $product ) {
    return 'Tech Specs';
}, 10, 2 );

specifico_show_table (filter)

Decide whether the table/tab renders for a product. Receives the current boolean and the product ID.

// Hide the spec table for a specific category.
add_filter( 'specifico_show_table', function ( $show, $product_id ) {
    if ( has_term( 'accessories', 'product_cat', $product_id ) ) {
        return false;
    }
    return $show;
}, 10, 2 );

specifico_table_groups (filter)

The most powerful hook — reshape the resolved data before it renders. Reorder, hide, or inject groups and rows. Receives the groups array and the product ID.

add_filter( 'specifico_table_groups', function ( $groups, $product_id ) {
    // Drop any group titled "Internal".
    return array_values( array_filter( $groups, function ( $group ) {
        return ( $group['title'] ?? '' ) !== 'Internal';
    } ) );
}, 10, 2 );

Presentation hooks

specifico_before_table / specifico_after_table (actions)

Output content immediately before or after the <table>. Each receives the groups array and product ID.

add_action( 'specifico_after_table', function ( $groups, $product_id ) {
    echo '<a class="datasheet" href="/datasheets/' . esc_attr( $product_id ) . '.pdf">Download datasheet</a>';
}, 10, 2 );

specifico_table_classes (filter)

Add CSS classes to the <table>. Receives the current class array and the style slug.

add_filter( 'specifico_table_classes', function ( $classes, $style ) {
    $classes[] = 'my-custom-spec-table';
    return $classes;
}, 10, 2 );

specifico_row_label / specifico_row_value (filters)

Format an individual cell. Each receives the value, the row data, and the product ID. The returned value is sanitized with wp_kses_post(), so links and basic HTML are allowed.

// Turn a "Datasheet" row's value into a link.
add_filter( 'specifico_row_value', function ( $value, $row, $product_id ) {
    if ( ( $row[0]['value'] ?? '' ) === 'Datasheet' ) {
        return '<a href="' . esc_url( $value ) . '">Download PDF</a>';
    }
    return $value;
}, 10, 3 );

Template override

For full control of the markup, copy the plugin's template into your theme:

wp-content/plugins/specifico/templates/specification-table.php
  → wp-content/themes/your-theme/specifico/specification-table.php

Specifico loads the theme copy if it exists, otherwise its own — the same mechanism WooCommerce uses, so it works on both classic and block themes. Edit your copy freely.

The following variables are available inside the template:
