How to make customer don't instantly reduce product quanity when ordered

[Yu5tas]

I sell unique items, so every item has only 1 quantity and when some customer orders it, product goes out of stock, even if he doesn't pay the money (others can't order it then). If I let users order items out of stock, then they can put more than 1 product to the cart.

 

So how can I forbid people put more than 1 product to cart or how to remove automatic quantity lowering?

you can for example disable the quantity input field

for that you have to add readonly="readonly" attribute for quantity field in your product.tpl file

 

then your customers will not have possibility to increase the quantity value.

 

 

this is the code:

<!-- quantity wanted -->
  <p id="quantity_wanted_p"{if (!$allow_oosp && $product->quantity <= 0) OR $virtual OR !$product->available_for_order OR $PS_CATALOG_MODE} style="display: none;"{/if}>
   <label>{l s='Quantity:'}</label>
   <input readonly="readonly" type="text" name="qty" id="quantity_wanted" class="text" value="{if isset($quantityBackup)}{$quantityBackup|intval}{else}{if $product->minimal_quantity > 1}{$product->minimal_quantity}{else}1{/if}{/if}" size="2" maxlength="3" {if $product->minimal_quantity > 1}onkeyup="checkMinimalQuantity({$product->minimal_quantity});"{/if} />
  </p>
