New button in product page

[Serial]

Hi,

 

I want to add a new button in product page.

 

I have just a problem with this. When I click on him, it's add the product in my cart.

But, I didn't want to do this. I want that on button click to redirect in a specific url of my shop.

 

I noticed that if my button is not in the form id="buy_block", it works.

 

How can I do to position my button in this form while redirect in a specific url ?

You probably added a submit button.

Can you place here the code for your button?

No it isn't ^^

{if $product->id_category_default != "100"}
<div class="box-echantillon" style="padding-bottom: 40px; padding-left: 13px; margin-top:-10px;">
<button id="btn_echantillon" class="btn btn-primary"><i class="fa fa-eyedropper"></i>
Acheter un échantillon (10x10cm)</button>
</div>
{/if}

Do you have a link of the page, you can share? Have the button inside the form.
