Hooks & Filters

ProductBay provides an extensive set of WordPress action hooks and filters, enabling developers to extend, customize, and integrate with the plugin without modifying its core source files.

Since v1.0.0

All hooks listed on this page were introduced in ProductBay 1.0.0, unless the hook notes a later version.

Hook Naming Convention

All hooks are prefixed with productbay_ to avoid collisions:

• Actions — Use do_action( 'productbay_*' )
• Filters — Use apply_filters( 'productbay_*' )

---

Core

Hooks fired during the plugin lifecycle.

productbay_loaded

Fires after all free plugin components are initialized. This is the primary hook for add-on plugins to bootstrap themselves.

Type	Action
Parameters	$plugin (Plugin) — The main plugin instance
File	app/Core/Plugin.php

add_action( 'productbay_loaded', function( $plugin ) {
    // Your add-on logic here
} );

productbay_admin_capability

Filters the capability required to reach the ProductBay admin screens and REST routes. Use it to delegate table management to a restricted role instead of full administrators.

Type	Filter
Parameters	$capability (string) — defaults to manage_options
Returns	string — A WordPress capability
File	app/Core/Constants.php
Since	1.3.1

add_filter( 'productbay_admin_capability', function() {
    return 'edit_products';
} );

productbay_admin_init

Fires after the admin component is set up (inside is_admin() context only).

Type	Action
Parameters	$admin (Admin) — The admin instance
File	app/Core/Plugin.php

---

Data Layer

Hooks around table CRUD operations in TableRepository.

productbay_before_save_table

Filters table data before it is persisted.

File	app/Data/TableRepository.php

add_filter( 'productbay_before_save_table', function( $data, $id ) {
    // Validate or modify data before save
    return $data;
}, 10, 2 );

productbay_after_save_table

Fires after a table is successfully saved.

Type	Action
Parameters	$post_id (int), $data (array)
File	app/Data/TableRepository.php

productbay_after_delete_table

add_filter( 'productbay_table_data', function( $data, $post ) {
    $data['my_pro_field'] = get_post_meta( $post->ID, '_my_pro_meta', true );
    return $data;
}, 10, 2 );

---

---

Frontend Rendering

The most critical layer for extending table output. All hooks are in TableRenderer.php unless noted otherwise.

productbay_query_args

Filters WP_Query arguments before the product query executes.

Type	Filter
Parameters	$args (array), $source (array), $settings (array)
Returns	array — Modified query args
File	app/Frontend/TableRenderer.php

add_filter( 'productbay_query_args', function( $args, $source, $settings ) {
    // Example: only show featured products
    $args['tax_query'][] = [
        'taxonomy' => 'product_visibility',
        'field'    => 'name',
        'terms'    => 'featured',
    ];
    return $args;
}, 10, 3 );

productbay_table_columns

Filters the columns array before rendering.

Type	Filter
Parameters	$columns (array), $table_id (int)
Returns	array — Modified columns

productbay_cell_output

Filters a single cell's HTML output.

Type	Filter
Parameters	$cell_html (string), $col (array), $product (WC_Product)
Returns	string — Modified HTML

add_filter( 'productbay_cell_output', function( $html, $col, $product ) {
    if ( $col['type'] === 'my_custom_type' ) {
        return '<span>' . esc_html( $product->get_attribute('brand') ) . '</span>';
    }
    return $html;
}, 10, 3 );

productbay_table_output

Filters the complete table HTML before it is returned.

Type	Filter
Parameters	$html (string), $table (array)
Returns	string — Modified HTML

productbay_table_styles

Filters the generated scoped CSS for a table.

Type	Filter
Parameters	$css (string), $table (array)
Returns	string — Modified CSS

Button & toggle text filters

Four filters override the customer-facing labels on a table's action controls. Each receives an empty string plus the table's resolved cart settings, so returning a non-empty string wins. Returning '' falls through to the global Cart Customization setting, and then to the built-in translatable default.

These are the seam ProductBay Pro uses to implement per-table custom text; a filter added at the default priority will run alongside it, so use a later priority if you need to override Pro.

Filter	Default label	Since
productbay_add_to_cart_text	WooCommerce's add-to-cart text	1.3.2
productbay_select_options_text	"Select Options" / "View Products"	1.3.2
productbay_bulk_list_text	"Add to bulk list"	1.3.4
productbay_bulk_list_added_text	"Added"	1.3.4

Type	Filter
Parameters	$text (string) — empty by default, $cart_settings (array) — the table's resolved cart settings
Returns	string — The label to render, or '' to fall back

// Call the bulk list an "order sheet" on every table.
add_filter( 'productbay_bulk_list_text', function( $text, $cart_settings ) {
    return __( 'Add to order sheet', 'my-textdomain' );
}, 10, 2 );

add_filter( 'productbay_bulk_list_added_text', function( $text, $cart_settings ) {
    return __( 'On sheet', 'my-textdomain' );
}, 10, 2 );

TIP

The bulk-list labels are always rendered — they give the select checkbox its accessible name on desktop, and become the visible toggle button on stacked mobile cards.

productbay_filter_options

Filters the choices offered by the category and product type dropdowns above a table.

Options are resolved from the table's own base product set — the source scope, ignoring the visitor's current selection — so the dropdowns never offer a value that would render an empty table. Use this filter to add a choice back (for example a category the table does not contain yet but soon will) or to drop one.

Type	Filter
Parameters	$options (array), $source (array), $settings (array), $table_id (int)
Returns	array — product_cat as a list of ['slug' => …, 'name' => …], product_type as a map of slug => label

add_filter( 'productbay_filter_options', function( $options, $source, $settings, $table_id ) {
    // Always offer the Clearance category, even while it is empty.
    $options['product_cat'][] = array( 'slug' => 'clearance', 'name' => __( 'Clearance', 'my-textdomain' ) );
    return $options;
}, 10, 4 );

productbay_filter_options_cache_ttl

Filters how long resolved filter choices stay cached, in seconds. Resolving them costs one ID-only product query plus two term queries, so the result is cached per table; the cache key carries a hash of the resolved query args, so editing a table's source takes effect immediately, while catalog changes are picked up when the transient expires.

Return 0 to disable caching — useful on a store whose product categories change constantly.

Type	Filter
Parameters	$ttl (int) — default 12 * HOUR_IN_SECONDS, $table_id (int)
Returns	int — Lifetime in seconds, or 0 to skip caching

productbay_render_filters

Action fired inside the filter bar, after the built-in category and product type dropdowns and before the Clear button. This is where add-ons inject their own filter controls — Pro's price range filter uses it.

Type	Action
Parameters	$settings (array), $source (array)
File	app/Frontend/TableRenderer.php

productbay_before_table / productbay_after_table

Actions fired before and after the table wrapper <div>.

Type	Action
Parameters	$table (array)

productbay_before_row / productbay_after_row

Actions fired before and after each product row <tr>.

Type	Action
Parameters	$product (WC_Product), $table (array)

productbay_toolbar_start / productbay_toolbar_end

Actions to inject content at the start or end of the toolbar area (above the table, where search and bulk actions live).

Type	Action
Parameters	$table (array)

Blocks & Preview

productbay_block_editor_css_paths

Filters the CSS files injected into the block editor's iframe, so a table rendered inside the editor looks like it does on the storefront. Return absolute filesystem paths, not URLs.

Type	Filter
Parameters	$paths (string[]) — absolute paths, defaults to the plugin's frontend.css and block-tabs.css
Returns	string[]
File	app/Blocks/BlockManager.php

    return $paths;
} );

productbay_preview_css_urls

Filters the stylesheet URLs loaded inside the admin live-preview iframe. The block editor equivalent above takes paths; this one takes URLs.

Type	Filter
Parameters	$css_urls (array) — defaults to the plugin's frontend.css
Returns	array
File	app/Api/PreviewController.php

---
