Virtuemart 2/Joomla 2.5.4浏览页面上的Virtuemart Add To Cart按钮

Question

我试着找出如何做到这一点，但就是不能解决，我试着在这里，谷歌和通过Virtuemart论坛搜索，但没有成功。

我正在尝试显示“类别”浏览页面上“产品详细信息”页面上的“添加到购物车”按钮。我之前在Virtuemart 1.1中使用以下代码做到了这一点：

<?php echo $form_addtocart ?>

然而，在Virtuemart2中尝试使用相同的代码时，我没有得到任何结果，尽管他们的指南仍然说明了这一点，就我所见：http://virtuemart.net/documentation/Developer_Manual/Modifying_the_Layout.html

我尝试从products页面复制完全相同的代码，但也不起作用，代码是：

<?php
// Add To Cart Button
if (!VmConfig::get('use_as_catalog', 0) and !empty($this->product->prices)) {
echo $this->loadTemplate('addtocart');
}  // Add To Cart Button END
?>

我要覆盖的文件位于：

/components/com_virtuemart/views/category/tmpl/default.php (the Category template)
/components/com_virtuemart/views/productdetails/tmpl/default.php (the Product page that the button is from)

如果我忽略了一些简单的东西，或者我遗漏了任何必要的信息，我深表歉意。

你好，阿莱克斯奈尔。

Answer 1

对于VM，它可能是一大堆东西。如果您没有调试工具，只需添加以下行，以查看是否满足条件(如Damien所提到的)：

echo "vmConfig says: |".VmConfig::get('use_as_catalog', 0)."|";
echo ", Product has prices?: |".$this->product->prices."|";
// Add To Cart Button
if (!VmConfig::get('use_as_catalog', 0) and !empty($this->product->prices)) {
    echo $this->loadTemplate('addtocart');
}  // Add To Cart Button END

如果两者都返回为true，那么它就是addtocart按钮的模板。

(示例：default_products.php)这将添加“添加到购物车按钮”

<form method="post" class="product" action="index.php" id="addtocartproduct<?php echo $product->virtuemart_product_id ?>">
        <?php // Product custom_fields
        if (!empty($product->customfieldsCart)) {  ?>
        <div class="product-fields">
            <?php foreach ($product->customfieldsCart as $field)
            { ?><div style="display:inline-block;" class="product-field product-field-type-<?php echo $field->field_type ?>">
                <span class="product-fields-title" ><b><?php echo  JText::_($field->custom_title) ?></b></span>
                <?php echo JHTML::tooltip($field->custom_tip,  JText::_($field->custom_title), 'tooltip.png'); ?>
                <span class="product-field-display"><?php echo $field->display ?></span>

                <span class="product-field-desc"><?php echo $field->custom_field_desc ?></span>
                </div><br/ >
                <?php
            }
            ?>
        </div>
        <?php }
         /* Product custom Childs
          * to display a simple link use $field->virtuemart_product_id as link to child product_id
          * custom_value is relation value to child
          */

        if (!empty($this->product->customsChilds)) {  ?>
            <div class="product-fields">
                <?php foreach ($this->product->customsChilds as $field) {  ?>
                    <div style="display:inline-block;" class="product-field product-field-type-<?php echo $field->field->field_type ?>">
                    <span class="product-fields-title" ><b><?php echo JText::_($field->field->custom_title) ?></b></span>
                    <span class="product-field-desc"><?php echo JText::_($field->field->custom_value) ?></span>
                    <span class="product-field-display"><?php echo $field->display ?></span>

                    </div><br/ >
                    <?php
                } ?>
            </div>
        <?php } ?>

            <div class="addtocart-bar">

                <?php // Display the quantity box ?>
