I'm developing an eCommerce site with WordPress+WooCommerce.
I added buttons to certain products in the Short Description field in order to quickly select certain number of products to be added in the cart (this is because I have different offers, for example: "Buy 4 for the price of 3").
I have a script like this in the general jquery file:
<script>
function pack4() { document.getElementById("quantity").value = "4"; }
function pack8() { document.getElementById("quantity").value = "8"; }
</script>
And this is an example of the code I have in some products Short Description:
<span><strong>4x3 Pack:</strong>TOTAL<strong>$1800</strong></span>
<button class="select" onclick="pack4()">Select</button>
Everything works and whenever you click on every button the order quantity adds the corresponding number.
The thing is: Whenever my client (who usually edits products) click on the Text/Visual flap of Short Description, the onclick="pack4()" code disappears. I guess WordPress/WooCommerce have got some jQuery filter that erases this kind of codes. I need it to stop doing that, because the client regularly edits things (and of course they don't know anything about coding). Otherwise, I have to add the code again every time.
I also suspect WP/WC also filters it without needing to click on this Text/Visual flap (but I might be wrong about that).
Anyone knows what to do?
Thanks!
