Having problems extending product view / addtocart class's (php and phtm)
Question
I need to preset the product quantity on the product page.
NB1: my products have new yes/no attribute defined in backend called formula_price-active. NB2: for formula_price_active product, I pass parameters via product url to pre-configure my product page
I then extended the view.php class to add/overload custom functions :
<?php
class Mine_Quotemodule_Block_Catalog_Product_View extends Mage_Catalog_Block_Product_View
{
/**
* Get default qty - either as preconfigured, or as 1.
* Also restricts it by minimal qty.
*
* @param null|Mage_Catalog_Model_Product $product
* @return int|float
*/
public function getProductDefaultQty($product = null)
{
if (!$product) {
$product = $this->getProduct();
}
$FPA_att_value = $product->getAttributeText('formula_price_active');
if (isset($FPA_att_value) && (($FPA_att_value == 'yes') || ($FPA_att_value == 'oui')))
{
$params = Mage::app()->getRequest()->getParams();
$urlParams = array();
foreach ($params as $name=>$value)
{
if ($name!="id")
{
$urlParams[$name] = base64_decode($value);
}
}
if (isset($urlParams['Devis_Qty']))
{
$qty = $urlParams['Devis_Qty'];
}
else
{
$qty = $this->getMinimalQty($product);
$config = $product->getPreconfiguredValues();
$configQty = $config->getQty();
if ($configQty > $qty) {
$qty = $configQty;
}
}
}
else
{
$qty = $this->getMinimalQty($product);
Mage::log('Qty'.$qty);
$config = $product->getPreconfiguredValues();
$configQty = $config->getQty();
Mage::log('configQty '.$configQty);
if ($configQty > $qty) {
$qty = $configQty;
}
}
Mage::log('Final Qty'.$qty);
return $qty;
}
public function testProductFP($product = null)
{
if (!$product) {
$product = $this->getProduct();
}
$FPA_att_value = $product->getAttributeText('formula_price_active');
if (isset($FPA_att_value) && (($FPA_att_value == 'yes') || ($FPA_att_value == 'oui')))
{
$params = Mage::app()->getRequest()->getParams();
$urlParams = array();
foreach ($params as $name=>$value)
{
if ($name!="id")
{
$urlParams[$name] = base64_decode($value);
}
}
if (isset($urlParams['Devis_Qty']))
{
$result = true;
}
else
{
$result = false;
}
}
else
{
$result = false;
}
return $result;
}
...
and the view.phtml to add custom stuffs (but theorically has nothing to do with the current problem):
…
<div class="extra-info">
<?php echo $this->getReviewsSummaryHtml($_product, 'default', false)?>
<!-- Modifs Perso -->
<!--<?php echo $this->getChildHtml('product_type_availability'); ?>-->
<?php echo $this->getDimHtml() ?>
<!-- ******************** -->
</div>
…
This seems to work well: - case 1: If formula_price_active is set to No or if it is set to yes but the needed parameters are not present, the basic getDefaultQuantity method is used -case 2: when the formula_price_active is set to Yes and parameters are OK, it sets the wanted qty.
I then added a custom addtocart.phtml in order to disable the quantity input in case 2.
BUT, when I add it to my layout.xml the problem appears :
in case 2 it is working, but in case 1, the quantity is set to 0 ?
What is strange,is that the qty layout changes as defined…
Here is my layout.xml
<?xml version="1.0"?>
<layout version="0.1.0">
<default>
<reference name="content">
</reference>
<reference name="head">
<action method="addItem"><type>skin_css</type><name>css/quote_form.css</name></action>
</reference>
</default>
<routeurfrontend_index_index>
<reference name="content">
<block type="quotemodule/quoteformblock" name="quoteform_quoteformblock"
template="quotemodule/quoteform.phtml" />
</reference>
</routeurfrontend_index_index>
<catalog_product_view>
<reference name="product.info">
<action method="setTemplate">
<template>quotemodule/catalog/product/view.phtml</template>
</action>
</reference>
<reference name="product.info.addtocart">
<action method="setTemplate">
<template>quotemodule/catalog/product/view/addtocart.phtml</template>
</action>
</reference>
</catalog_product_view>
</layout>
Thank you for your help,
Solution
That was a stupid mistake…Sorry…
I based my addtocart.phtml on the wrong template (base/default instead of rwd/default). The base/default one does not replace the qty value by 1 if getProductDefaultQty returns null whereas the rwd/default does :
base/default addtocart.phtml
<input type="text" name="qty" id="qty" maxlength="12" value="<?php echo $this->getProductDefaultQty() * 1 ?>" title="<?php echo $this->__('Qty') ?>" class="input-text qty" />
rwd/default addtocart.phtml
<input type="text" pattern="\d*" name="qty" id="qty" maxlength="12" value="<?php echo max($this->getProductDefaultQty() * 1, 1) ?>" title="<?php echo $this->__('Qty') ?>" class="input-text qty" />
