FAQ

Does it require WooCommerce?

Yes. Sizer extends WooCommerce single product pages and does nothing without WooCommerce active. The plugin header declares WooCommerce as a required plugin.

Where does the size guide appear?

Always as a button just below the add-to-cart button on the single product page (hooked to woocommerce_after_add_to_cart_button at priority 15). There is no placement setting, placement is fixed so the guide lands in a predictable, discoverable spot.

Can I reuse one chart on many products?

Yes. Build a chart once under WooCommerce → Size Guides → Size charts, then assign it on each product’s Product data → Size guide tab. The same chart can be assigned to any number of products.

Can I assign a chart to a whole category?

Not in the free edition, assignment is per product only. A store-wide default chart (shown on every product with no explicit assignment) is the shipped Sizer Pro feature. Developers can implement other fallback logic with the sizer/resolved_chart_id filter.

Can I choose a text link instead of a button, or show the chart in a product tab?

No. The trigger is always a styled button, and the chart always opens in a modal <dialog>. There is no text-link variant and no inline product-tab display. You can restyle the button with CSS or replace the markup with a theme template override.

Is the modal accessible?

Yes. It is a native <dialog> opened with showModal(), which keeps focus inside while open. The close (×) button is focused on open, Escape and a backdrop click both close it, and focus returns to the Size guide button on close. The chart table uses <th scope="col"> and <th scope="row"> so screen readers announce each cell in context.

What happens on a browser without <dialog> support?

The script falls back to toggling the element’s visibility, so the chart still opens and closes. Modern evergreen browsers all support <dialog> and use the native modal path.

Can I change the wording?

Yes, two settings on the Settings tab: Link wording (the button text) and Pop-up heading (the dialog title). Leave the heading blank to reuse the button text; leave the button text blank to fall back to “Size guide”.

Can I override the styling or markup?

Yes. Copy single-product/trigger.php, dialog.php or chart-table.php into your theme under yourtheme/sizer/single-product/ to override the markup, and re-theme the look with the --sizer-* CSS custom properties. The output is dark-mode aware and respects prefers-reduced-motion.

Is there a shortcode?

No. The button is injected automatically after the add-to-cart button; there is nothing to place by hand. Developers can change which chart resolves with the sizer/resolved_chart_id filter.

What shows on a product with no chart?

Nothing, no button and no dialog, and no Sizer CSS or JS is enqueued on that page. You can roll size guides out one product at a time.

What happens to my charts if I uninstall?

Deleting the plugin removes the sizer_settings, sizer_charts and sizer_db_version options, so your charts and wording settings are gone. The per-product _sizer_chart_id meta is left in place, so if you reinstall and rebuild the same chart ids, existing product assignments still resolve.

What does Sizer Pro add?

Shipped today: a store-wide default chart for products with no per-product assignment (DefaultChart), and per-variation charts on variable products that update the modal as shoppers switch variations (VariationCharts). Both build on the sizer/resolved_chart_id filter and variation meta, with no extra database tables. cm/inch unit switching, a “find my size” calculator and CSV import/export are on the Pro roadmap.
