Variable Product SKU Display

I think this might be a bug.

In meta.php, the if statement includes “variable” so I guess it should be displaying…
if ( $product->is_type( array( 'simple', 'variable' ) )

Any idea of how to access an array of SKU’s for a variable product?

Hey Sean,

This was a bug i raised to the WC developers via github.

It has now been fixed for ready for 1.7 …

Do you want the fix to get it working on 1.6.5.2?

Many Thanks
Samuel

Yes, that would be great thanks Samuel.
I have a client quite eager to get this fixed before they go live.

Thanks,
Sean K.

Hi Samuel,

I would also be interested in the fix for this.

Thanks,
Jeff

Finally found this! I am having the same problem. Could you share the fix with us Samuel?

Thank you,
Alice

I need this fix please.
Why would they wait til 1.7?

Hi,

Sorry for such a late response.

here is the fix..

replace your add-to-cart-variation.js with the following code

jQuery(document).ready(function($) {

	/**

	$('form.variations_form')

		} )

Dear samueljeden,

It’s nice to see solution, but this code seems to have syntax error.
I have fix it (see below).

I’m using Woocommerce 1.6.6 and still sku for variable product isn’t visible.

add-to-cart-variation-min.js (fixed)

jQuery(document).ready(function(e){function t(e,t){var r=[];for(var i=0;i<e.length;i++){var s=e[i],o=s.variation_id;n(s.attributes,t)&&r.push(s)}return r}function n(e,t){var n=!0;for(attr_name in e){var r=e[attr_name],i=t[attr_name];r!==undefined&&i!==undefined&&r.length!=0&&i.length!=0&&r!=i&&(n=!1)}return n}e("form.variations_form").on("click",".reset_variations",function(t){e(this).closest("form.variations_form").find(".variations select").val("").change();return!1}).on("change",".variations select",function(t){$variation_form=e(this).closest("form.variations_form");$variation_form.find("input[name=variation_id]").val("").change();$variation_form.trigger("woocommerce_variation_select_change").trigger("check_variations",["",!1]);e(this).blur();e().uniform&&e.isFunction(e.uniform.update)&&e.uniform.update()}).on("focusin",".variations select",function(t){$variation_form=e(this).closest("form.variations_form");$variation_form.trigger("woocommerce_variation_select_focusin").trigger("check_variations",[e(this).attr("name"),!0])}).on("check_variations",function(n,r,i){var s=!0,o=!1,u=!1,a={},f=e(this),l=f.find(".reset_variations");f.find(".variations select").each(function(){e(this).val().length==0?s=!1:o=!0;if(r&&e(this).attr("name")==r){s=!1;a[e(this).attr("name")]=""}else{value=e(this).val().replace(/&/g,"&").replace(/"/g,'"').replace(/'/g,"'").replace(/</g,"<").replace(/>/g,">");a[e(this).attr("name")]=value}});var c=parseInt(f.attr("data-product_id")),h=window["product_variations_"+c];h||(h=window.product_variations);var p=t(h,a);if(s){var d=p.pop();if(d){f.find("input[name=variation_id]").val(d.variation_id).change();f.trigger("found_variation",[d])}else{f.find(".variations select").val("");i||f.trigger("reset_image")}}else{f.trigger("update_variation_values",[p]);i||f.trigger("reset_image");r||f.find(".single_variation_wrap").slideUp("200")}o?l.css("visibility")=="hidden"&&l.css("visibility","visible").hide().fadeIn():l.css("visibility","hidden")}).on("reset_image",function(t){var n=e(this).closest(".product"),r=n.find("div.images img:eq(0)"),i=n.find("div.images a.zoom:eq(0)"),s=r.attr("data-o_src"),o=r.attr("data-o_title"),u=i.attr("data-o_href");if(s&&u&&o){r.attr("src",s).attr("alt",o).attr("title",o);i.attr("href",u)}}).on("update_variation_values",function(t,n){$variation_form=e(this).closest("form.variations_form");$variation_form.find(".variations select").each(function(t,r){current_attr_select=e(r);current_attr_select.find("option:gt(0)").attr("disabled","disabled");var i=current_attr_select.attr("name");for(num in n){var s=n[num].attributes;for(attr_name in s){var o=s[attr_name];if(attr_name==i)if(o){o=e("<div/>").html(o).text();o=o.replace(/'/g,"\\'");o=o.replace(/"/g,'\\"');current_attr_select.find('option[value="'+o+'"]').removeAttr("disabled")}else current_attr_select.find("option").removeAttr("disabled")}}});$variation_form.trigger("woocommerce_update_variation_values")}).on("found_variation",function(t,n){var r=e(this),i=e(this).closest(".product"),s=i.find("div.images img:eq(0)"),o=i.find("div.images a.zoom:eq(0)"),u=s.attr("data-o_src"),a=s.attr("data-o_title"),f=o.attr("data-o_href"),l=n.image_src,c=n.image_link,h=n.image_title;r.find(".variations_button").show();r.find(".single_variation").html(n.price_html+n.availability_html);if(!u){u=s.attr("src")?s.attr("src"):"";s.attr("data-o_src",u)}if(!f){f=o.attr("href")?o.attr("href"):"";o.attr("data-o_href",f)}if(!a){a=s.attr("title")?s.attr("title"):"";s.attr("data-o_title",a)}if(l&&l.length>1){s.attr("src",l).attr("alt",h).attr("title",h);o.attr("href",c)}else{s.attr("src",u).attr("alt",a).attr("title",a);o.attr("href",f)}var p=r.find(".single_variation_wrap");n.sku?i.find(".product_meta").find(".sku").text(n.sku):i.find(".product_meta").find(".sku").text("");p.find(".quantity").show();!n.is_in_stock&&!n.backorders_allowed&&r.find(".variations_button").hide();n.min_qty?p.find("input[name=quantity]").attr("data-min",n.min_qty).val(n.min_qty):p.find("input[name=quantity]").removeAttr("data-min");n.max_qty?p.find("input[name=quantity]").attr("data-max",n.max_qty):p.find("input[name=quantity]").removeAttr("data-max");if(n.is_sold_individually=="yes"){p.find("input[name=quantity]").val("1");p.find(".quantity").hide()}p.slideDown("200").trigger("show_variation",[n])});e("form.variations_form .variations select").change()});

Thank you for the code but same with lorsabyan, the SKU is still not appearing when choosing the variables. I have left the main SKU blank as stated in the docs and added a different SKU for each variable but it is still blank on the front end. ??

My apologies for the syntax error.

You are required to have a parent sku for it to show.

Many Thanks
