Codeigniter 在购物车上添加产品

朋友们，我正在开发一个电子商务网站（使用Codeigniter）

在客户填写产品数量并单击“购买”后，只有“数量”字段的产品才能在购物车中填写。你能帮我吗

HTML:

<form>
<ul class="products-list">
    <li class="product">
        <input type="hidden" class="product_id" value="1">
        <span class="product-name">Product 1</span>
        <span class="product-value">$ 100</span> 
        <span>Qnt. <input type="text" class="quantity"></span> 
    </li>
        <li class="product">
        <input type="hidden" class="product_id" value="2">
        <span class="product-name">Product 2</span>
        <span class="product-value">$ 100</span> 
        <span>Qnt. <input type="text" class="quantity"></span> 
    </li>
</ul>
<button>Buy</button>
</form>

$.ajax({
    url: '/cart/add/'+product_id+'/'+quantity,
    type: 'GET',
    success: function( data ){
        if ( data != false ) {
            window.location.reload();
        }
    }
});

public function addItem( $product_id, $quantity){ 
    $product = $this->Produto_model->getById($product_id); 
    $this->carrinho->setItem($product, $quantity); 
    echo json_encode($this->carrinho); 
}

我的PHP代码：

<form>
<ul class="products-list">
    <li class="product">
        <input type="hidden" class="product_id" value="1">
        <span class="product-name">Product 1</span>
        <span class="product-value">$ 100</span> 
        <span>Qnt. <input type="text" class="quantity"></span> 
    </li>
        <li class="product">
        <input type="hidden" class="product_id" value="2">
        <span class="product-name">Product 2</span>
        <span class="product-value">$ 100</span> 
        <span>Qnt. <input type="text" class="quantity"></span> 
    </li>
</ul>
<button>Buy</button>
</form>

$.ajax({
    url: '/cart/add/'+product_id+'/'+quantity,
    type: 'GET',
    success: function( data ){
        if ( data != false ) {
            window.location.reload();
        }
    }
});

public function addItem( $product_id, $quantity){ 
    $product = $this->Produto_model->getById($product_id); 
    $this->carrinho->setItem($product, $quantity); 
    echo json_encode($this->carrinho); 
}  

像这样试试

你的问题是什么？什么有效，什么无效？哪里出错了？好的，我在routes.php文件中做了什么？当前看起来是这样的：$route['cart/add/（：num）/（：num）']=“front/products/addItem/$1/$2”<代码>$route['cart/add/']=“front/products/addItem/”
