Show an additional time if order beyond the quantity in stock

[Denys06]

Hello everyone, I'm posting this topic because I am facing a problem with the cart prestashop. In first time sorry for my bad English

 

I currently have adapted the code to my basket the products displayed a colored depending on the availability of the product:[/font]

 

 

My concern is that for the first product in this basket, there is only one copy in stock, out here indicating 3 in the desired amount, it still indicates that the product is in stock which is incorrect vis-à-vis the client.

 

I would like if the client indicates an amount above the stock available, the green picture should be replaced by an orange, or even better: the product is duplicated with the first quantity 1 in green and the second a amount of 2 orange.

 

Here is the line of code in my file shopping-cart-product-line.tpl



    <td class="cart_ref" align="center">
    {if $product.quantity_available > 0}
        <img src="{$img_dir}pr_avail.png" alt="{l s='Available'}" title="{l s='Available'}">
    {else if $product.quantity_available <= 0 && $product.allow_oosp}
        <img src="{$img_dir}pr_preorder.png" alt="{l s='On Backorder'}" title="{l s='On Backorder'}">
    {else if $product.quantity_available <= 0 && !$product.allow_oosp}
        <img src="{$img_dir}pr_oost.png" alt="{l s='Out of stock'}" title="{l s='Out of stock'}">
    {/if}
</td>

 

 Thank you in advance for your help
