Conditional logic for WooCommerce product options

Ask for artwork only after someone picks a printed finish. The page stays short, and nobody pays for a choice that does not apply. Three steps, free.

A printed T-shirt product page asking for Colour, Size and Artwork, each marked Required. Artwork offers Upload my artwork, Design it for me +£15.00 and No print, plain tee -£3.00. There is no file upload on the page, and the count reads 0 of 3 chosen.
Before a pick: no upload on the page.
The same page after Upload my artwork is picked. The artwork question shows a tick and the note JPG, PNG or PDF. We check every file before print. A Your artwork file upload, marked Required, has appeared under it, and the count reads 1 of 4 chosen.
After Upload my artwork: the upload appears.

Set it up

You need AddOnBoss, free from WordPress.org.

  1. Edit the product and open the Product options tab. Attach the set that decides, then add the question that depends on it below it.

    Here the artwork set comes first. The Your artwork file upload, added from Add a field, sits under it. A rule can only read a question above it.

    The Product options tab of a printed T-shirt. Under Options this product comes in, three sets are attached, Guide tee colours, Guide tee sizes and Guide artwork, each set to Required. Below them, a Your artwork file field reads Required, shown by a rule. Under the rows are Attach an option set, Add a field and Add a section.

  2. Open the question that waits, press Edit rule, and pick the answer that shows it.

    Keep Available only when, then choose the artwork set, is, Upload my artwork. Choose Hidden when for the reverse. What the customer sees shows the field both ways.

    The rule editor. Its sentence reads Available only when Guide artwork is Upload my artwork, with Done. Below are the boxes Available only when, then Guide artwork, is, Upload my artwork, with + Add another condition and Or when. Under What the customer sees, two panes: with the artwork unanswered the field is not shown, answered it is shown.

  3. Press Done, then Update. The upload now appears only for the customer who picks Upload my artwork.

Free to start. Show and hide rules are in the free plugin. The upload in this example is Pro.

Common questions

Can WooCommerce show a product option only when another is chosen?

Not on its own. Core WooCommerce has variations, which cannot depend on one another this way, so you need a product options plugin with conditional logic. AddOnBoss does it in the free plugin.

Will a hidden option still be charged or block the basket?

No. While a question is hidden nothing in it is charged, it is never required, and anything already picked or typed in it clears. That holds when the order is placed too, not just on the page.

Can one rule depend on two answers?

Yes. Press + Add another condition for "and", or Or when for "or". So "Finish is Embroidered and Quantity is more than 25, or when Finish is Printed" is one rule.

What is free and what is Pro?

Show and hide rules are free, with no limit on how many you write. They test a choice with is, is not, is any of and is answered, and a field with is ticked, has a file or is filled in. Rules that compare a number, is more than, is less than and is exactly, are in AddOnBoss Pro, as are file uploads.

Every setting: conditional options documentation. Or start earlier: add product options without variations.
