Support » Plugin: WooCommerce » How to Have Variable Products Only Show Valid Combinations

  • Resolved pmbrenner91


    Good morning!

    I have a variable product created on my website:


    What I’d like is for certain options to become unavailable depending on the previous selected option.

    So, selecting a “Pole Flag” item type will eliminated non-pole flag sizes under the size option.

    If the customer isn’t paying attention and selects a feather flag size for a teardrop flag, an error is displayed: “Sorry, no products matched your selection. Please choose a different combination.”

    I’d like to avoid that error by forcibly removing the options that would allow a customer to arrive at this error.

    Does that make sense?

  • This looks similar to a question Mr Jolley answered a little while ago.

    Have a look at this:

    His answer, not mine!


    Thanks a bunch for the prompt response! It’s not a product dependency, as in this product is not dependent on any other product. This product’s options is dependent on options of the same product. Will this plugin still help?

    Works perfect.

    Hey there,

    I do not understand the Answer Mike gave. It has only to do with how to handle 20 variations but not with how to trigger an event to reload only valid combinations.

    Or do I get something wrong?

    Is there a solution for this problem?

    Thanks in Advance,


    Hi everybody, same problem here, any news?

    hi there,

    I do have same issue…
    I do literally need the elimination of non possible options and I do have nearly 500 variations(with 5 different options).
    Unfortunately link to snippet posted by @mikejolley is no longer working…
    Any chance it can be posted directly here?


    add_filter( 'woocommerce_ajax_variation_threshold', 'custom_threshold', 40 );
    function custom_threshold( ) {
      return 500;

    Beware if the threshold is too big, page size will increase to the point where performance may suffer, particularly for users on slow connections.


    Works perfect…
    thanks a lot for this

    I have to say that it still loads reasonably fast…
    …I nearly did not noticed difference and I do have truly 497 variations

    I guess if each of them has special picture or lots of details, then it may slow it down considerably

    I think any problem will be for mobile users who live in parts of the country not reached by 4G. In the UK, cities are well covered but coverage in some rural areas is patchy. Depends on the typical customer for your store.

    again, can someone detail the complete approach when using the snippet? How does the snippet help? Where does one set the dependencies?

    Make a child theme:
    This is to make your customisations update-safe.

    Put the snippet in functions.php in the root of child theme. The first line in functions.php must be <?php.

    Where the number of variations is greater than the default 20 threshold, WooCommerce will not load the variations with the page, This is to limit the data sent with the page, and this limits page load time. After the page has loaded, the customer will make a selection(s). An Ajax call is used to fetch the variation data. Sometimes the variation is unavailable, and the customer will get an annoying “This variation is unavailable” message.

    If the snippet is used to raise the threshold above the number of variations, all variation data is loaded with the page and the customer cannot select variations which are not available. The downside is page load time may increase, particularly for users on poor connections. The webmaster will have to make a judgement.

    There are no dependencies.
