Question

我目前正在修改开源PHP POS，我想修改代码而不是显示警告并显示0个库存项目，如果数量为0则不显示结果。

我设法将消息从正常消息更改为javascript弹出窗口但是我仍然不想显示该项目。因为使用这个系统的我的工作人员总是忽略弹出窗口，而当月底它显示了相当多的负面项目并且让我难以检查和改变。因此，我在这里寻求专业帮助，为我提供建议和帮助。我看起来高低，并设法得到一堆代码，我相信它可能是那个。如果我错了，请纠正我。

代码：

function add_item($item_id,$quantity=1,$discount=0,$price=null,$description=null,$serialnumber=null)
{
    //make sure item exists
    if(!$this->CI->Item->exists($item_id))
    {
        //try to get item id given an item_number
        $item_id = $this->CI->Item->get_item_id($item_id);

        if(!$item_id)
            return false;
    }


    //Alain Serialization and Description

    //Get all items in the cart so far...
    $items = $this->get_cart();

    //We need to loop through all items in the cart.
    //If the item is already there, get it's key($updatekey).
    //We also need to get the next key that we are going to use in case we need to add the
    //item to the cart. Since items can be deleted, we can't use a count. we use the highest key + 1.

    $maxkey=0;                       //Highest key so far
    $itemalreadyinsale=FALSE;        //We did not find the item yet.
    $insertkey=0;                    //Key to use for new entry.
    $updatekey=0;                    //Key to use to update(quantity)

    foreach ($items as $item)
    {
        //We primed the loop so maxkey is 0 the first time.
        //Also, we have stored the key in the element itself so we can compare.

        if($maxkey <= $item['line'])
        {
            $maxkey = $item['line'];
        }

        if($item['item_id']==$item_id)
        {
            $itemalreadyinsale=TRUE;
            $updatekey=$item['line'];
        }
    }

    $insertkey=$maxkey+1;

    //array/cart records are identified by $insertkey and item_id is just another field.
    $item = array(($insertkey)=>
    array(
        'item_id'=>$item_id,
        'line'=>$insertkey,
        'name'=>$this->CI->Item->get_info($item_id)->name,
        'item_number'=>$this->CI->Item->get_info($item_id)->item_number,
        'description'=>$description!=null ? $description: $this->CI->Item->get_info($item_id)->description,
        'serialnumber'=>$serialnumber!=null ? $serialnumber: '',
        'allow_alt_description'=>$this->CI->Item->get_info($item_id)->allow_alt_description,
        'is_serialized'=>$this->CI->Item->get_info($item_id)->is_serialized,
        'quantity'=>$quantity,
        'discount'=>$discount,
        'price'=>$price!=null ? $price: $this->CI->Item->get_info($item_id)->unit_price
        )
    );

    //Item already exists and is not serialized, add to quantity
    if($itemalreadyinsale && ($this->CI->Item->get_info($item_id)->is_serialized ==0) )
    {
        $items[$updatekey]['quantity']+=$quantity;
    }
    else
    {
        //add to existing array
        $items+=$item;
    }

    $this->set_cart($items);
    return true;

}

function out_of_stock($item_id)
{
    //make sure item exists
    if(!$this->CI->Item->exists($item_id))
    {
        //try to get item id given an item_number
        $item_id = $this->CI->Item->get_item_id($item_id);

        if(!$item_id)
            return false;
    }

    $item = $this->CI->Item->get_info($item_id);
    $quanity_added = $this->get_quantity_already_added($item_id);

    if ($item->quantity - $quanity_added < 0)
    {
        return true;
    }

    return false;
}

提前谢谢！杰夫

你只显示前端的代码（“模板”），不幸的是这段代码显然缺少一些部分 - 至少表格行应该在那里。

但是我认为缺少的</tr>元素会出现在代码片段之后。

我在这里所做的只是将包含产品的<tr>置于一个条件中，这样只有当库存数量为＆gt;时才会显示它。 0

关于新代码 - 你有一个名为“out_of_stock”的函数，我试着在add_item的开头调用这个函数。请注意，这只是猜测，因为我不知道您的商店系统的内在因素：

function add_item($item_id,$quantity=1,$discount=0,$price=null,$description=null,$serialnumber=null)
{
//make sure item exists
if(!$this->CI->Item->exists($item_id))
{
    //try to get item id given an item_number
    $item_id = $this->CI->Item->get_item_id($item_id);

    if(!$item_id)
        return false;
}

// add the out-of-stock check here
if (out_ot_stock($item_id)) {
    return false;
}

// continue with the rest of code

php pos inventory：如果数量为0，则不显示结果
