How to pull products from a category on an extra check-out step I already have?

Question

I installed a plugin to add an extra check-out step to present more cross-sell products from here:

How to add a custom page with cross-sell products

And it works great - the page comes up and loads the cross-sells but now I need to pull the products from a category instead of the actual cross-sell products because I intend to change the cross-sells every once in a while and it would be nearly impossible to change cross-sells in 1300 products manually...

Any idea how I can do that?

Magento 1.9.1.0

Here is the actual code I used to add the extra check-out step:

https://github.com/tmhub/suggestpage

Edited on January 19th, 2017:

Let me just clarify from the very beginning...

There are a few things I did:

1. I installed the SuggestPage plugin from here: https://github.com/tmhub/suggestpage

that gave me the extra page in the check-out.

Then 2. I modified the IndexController.php file in:

/home/myAccount/public_html/app/code/community/TM/SuggestPage/controllers/backupINDEXCONTROLLER/IndexController.php

In order to:

1. Display cross-sell products on the extra check-out page

and

2. Give the option for customers to enter a coupon.

The original IndexController.php looked liked this:

<?php
class TM_SuggestPage_IndexController extends Mage_Core_Controller_Front_Action
{
    public function indexAction()
    {
        $this->loadLayout()
            ->_initLayoutMessages('checkout/session')
            ->_initLayoutMessages('catalog/session');
        $this->renderLayout();
    }
}

My modified IndexController.php looks like this:

<?php

class TM_SuggestPage_IndexController extends Mage_Core_Controller_Front_Action
{
    public function indexAction()

{

    $this->loadLayout()
        ->_initLayoutMessages('checkout/session')
        ->_initLayoutMessages('catalog/session');

$block2 =  $this->getLayout()->createBlock('checkout/cart_coupon')->setTemplate('checkout/cart/coupon.phtml');
$this->getLayout()->getBlock('content')->append($block2);

    $_product = Mage::getModel('catalog/product')->load(1); //here 1 is product Id
    $block = $this->getLayout()->createBlock('checkout/cart_crosssell')->setProduct($_product)->setTemplate('checkout/cart/crosssell.phtml'); $this->getLayout()->getBlock('content')->append($block);

    $this->renderLayout();
    }
}

This works and it works great displaying the cross-sell products!

Now what I am trying to do is display the products from a category (category ID=190) instead of actually displaying the cross-sell products. There are 2 gentlemen who have been trying to help me with this and I appreciate that very much - Murtuza Zabuawala and Piyush. They both have different approaches on how to do this:

Murtuza Zabuawala (in his answer below) says to add the following code to the IndexController.php file in:

/home/myAccount/public_html/app/code/community/TM/SuggestPage/controllers/backupINDEXCONTROLLER/IndexController.php

$this->loadLayout()
    ->_initLayoutMessages('checkout/session')
    ->_initLayoutMessages('catalog/session');

 $category = Mage::getModel('catalog/category')->load(11); //here 11 is category id
 $block    = $this->getLayout()->createBlock('catalog/product_list')->setCategory($category)->setTemplate('catalog/product/list.phtml');
 $this->getLayout()->getBlock('content')->append($block);
 $this->renderLayout();

But when I do that - my IndexController.php file looks like this (it's possible I am doing it wrong):

<?php

class TM_SuggestPage_IndexController extends Mage_Core_Controller_Front_Action
{
    public function indexAction()

{

    $this->loadLayout()
        ->_initLayoutMessages('checkout/session')
        ->_initLayoutMessages('catalog/session');

 $category = Mage::getModel('catalog/category')->load(190); //here 11 is category id
 $block    = $this->getLayout()->createBlock('catalog/product_list')->setCategory($category)->setTemplate('catalog/product/list.phtml');
 $this->getLayout()->getBlock('content')->append($block);

    $this->renderLayout();
    }
}

And it gives the following Error:

There has been an error processing your request

SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ')' at line 1, query was: SELECT `mg_catalog_category_entity`.* FROM `mg_catalog_category_entity` WHERE (entity_id =)

If I try to make my IndexController.php like this:

<?php



class TM_SuggestPage_IndexController extends Mage_Core_Controller_Front_Action
{
    public function indexAction()

{

    $this->loadLayout()
        ->_initLayoutMessages('checkout/session')
        ->_initLayoutMessages('catalog/session');


$block2 =  $this->getLayout()->createBlock('checkout/cart_coupon')->setTemplate('checkout/cart/coupon.phtml');
$this->getLayout()->getBlock('content')->append($block2);

    $_product = Mage::getModel('catalog/product')->load(1); //here 1 is product Id
    $block = $this->getLayout()->createBlock('checkout/cart_crosssell')->setProduct($_product)->setTemplate('checkout/cart/crosssell.phtml'); $this->getLayout()->getBlock('content')->append($block);


    $this->renderLayout();

     $this->loadLayout()
    ->_initLayoutMessages('checkout/session')
    ->_initLayoutMessages('catalog/session');


 $category = Mage::getModel('catalog/category')->load(190); //here 11 is category id
 $block    = $this->getLayout()->createBlock('catalog/product_list')->setCategory($category)->setTemplate('catalog/product/list.phtml');
 $this->getLayout()->getBlock('content')->append($block);


 $this->renderLayout();


    }
}

It gives this Error:

The truth is - I don't know how to modify the IndexController.php file and it's entirely possible I am doing it wrong and therefore getting these Errors.

If I try to do what Piyush is suggesting (in his answer also below) which is to replace the following code in app/code/community/TM/SuggestPage/Block/Cart.php

getLastAddedQuoteItems() function in app/code/community/TM/SuggestPage/Block/Cart.php

with this code:

public function getLastAddedQuoteItems()
{
    $items = Mage::getModel('catalog/category')->load('your_category_id')
             ->getProductCollection()
             ->addAttributeToSelect('*')
             ->addAttributeToFilter('status', 1)
             ->addAttributeToFilter('visibility', 4)
             ;
    $this->_lastAddedQuoteItems = $items;

    return $this->_lastAddedQuoteItems;
}

then my Cart.php file looks like this (again - I'm not sure if I'm doing this right):

<?php
class TM_SuggestPage_Block_Cart extends Mage_Checkout_Block_Cart_Sidebar
{
    protected $_lastAddedQuoteItems = null;
    protected function _prepareLayout()
    {
        if (!Mage::registry('product')) {
            $productId = Mage::getSingleton('checkout/session')->getSuggestpageProductId();
            if (!$productId) {
                return false;
            }
            $product = Mage::getModel('catalog/product')
                ->setStoreId(Mage::app()->getStore()->getId())
                ->load($productId);
            if (!$product->getId()) {
                return false;
            }
            Mage::register('product', $product);
        }
    }
   public function getLastAddedQuoteItems()
{
    $items = Mage::getModel('catalog/category')->load('190')
             ->getProductCollection()
             ->addAttributeToSelect('*')
             ->addAttributeToFilter('status', 1)
             ->addAttributeToFilter('visibility', 4)
             ;
    $this->_lastAddedQuoteItems = $items;

    return $this->_lastAddedQuoteItems;
}
}

and I get the following Error message:

--- Hand Made light was added to your shopping cart.

Fatal error: Call to a member function isVisibleInSiteVisibility() on a non-object in /home/myACCOUNT/public_html/app/design/frontend/base/default/template/checkout/cart/sidebar/default.phtml on line 29

It is also possible that I am modifying this file wrong...

If I make my Cart.php file look like this:

<?php
class TM_SuggestPage_Block_Cart extends Mage_Checkout_Block_Cart_Sidebar
{
    protected $_lastAddedQuoteItems = null;
    protected function _prepareLayout()
    {
        if (!Mage::registry('product')) {
            $productId = Mage::getSingleton('checkout/session')->getSuggestpageProductId();
            if (!$productId) {
                return false;
            }
            $product = Mage::getModel('catalog/product')
                ->setStoreId(Mage::app()->getStore()->getId())
                ->load($productId);
            if (!$product->getId()) {
                return false;
            }
            Mage::register('product', $product);
        }
    }
    public function getLastAddedQuoteItems()
    {
        if (null === $this->_lastAddedQuoteItems) {
           $items = Mage::getModel('catalog/category')->load('190')
             ->getProductCollection()
             ->addAttributeToSelect('*')
             ->addAttributeToFilter('status', 1)
             ->addAttributeToFilter('visibility', 4)
             ;
    $this->_lastAddedQuoteItems = $items;

    return $this->_lastAddedQuoteItems;
}
}

It gives the following Error:

Edited later on January 19th, 2017:

Murtuza Zabuawala (thank you for trying) suggested to try a different code and so I made my IndexController.php in /home/myACCOUNT/public_html/app/code/community/TM/SuggestPage/controllers/

look like this:

<?php

class TM_SuggestPage_IndexController extends Mage_Core_Controller_Front_Action
{
    public function indexAction()

    {

        $this->loadLayout()
            ->_initLayoutMessages('checkout/session')
            ->_initLayoutMessages('catalog/session');


     $block = $this->getLayout()->createBlock('catalog/product_list')->setCategoryId(190)->setTemplate('catalog/product/list.phtml'); 
     $this->getLayout()->getBlock('content')->append($block);


        $this->renderLayout();
        }
    }

but that gives the following Error:

There has been an error processing your request
SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ')' at line 1, query was: SELECT `mg_catalog_category_entity`.* FROM `mg_catalog_category_entity` WHERE (entity_id =)

------Edited on January 18th:

I am really open to ANY solution that allows me to up-sell (I'm using this as a business term not Magento jargon here = Would you like some fries with that? kind of a thing...) on a separate page of the checkout (preferably after the customer adds the product and before they login to check out....

Edited on January 16th in response to an answer given by Piyush bellow:

Here is the ORIGINAL Cart.php file:

    <?php
class TM_SuggestPage_Block_Cart extends Mage_Checkout_Block_Cart_Sidebar
{
    protected $_lastAddedQuoteItems = null;
    protected function _prepareLayout()
    {
        if (!Mage::registry('product')) {
            $productId = Mage::getSingleton('checkout/session')->getSuggestpageProductId();
            if (!$productId) {
                return false;
            }
            $product = Mage::getModel('catalog/product')
                ->setStoreId(Mage::app()->getStore()->getId())
                ->load($productId);
            if (!$product->getId()) {
                return false;
            }
            Mage::register('product', $product);
        }
    }
    public function getLastAddedQuoteItems()
    {
        if (null === $this->_lastAddedQuoteItems) {
            $itemIds = Mage::getSingleton('checkout/session')->getSuggestpageQuoteItemIds();
            if (!$itemIds) {
                return false;
            }
            $items = array();
            $cartItems = $this->getItems();
            foreach ($cartItems as $cartItem) {
                if (in_array($cartItem->getId(), $itemIds)) {
                    $items[] = $cartItem;
                }
            }
            if (!$items) {
                return false;
            }
            $this->_lastAddedQuoteItems = $items;
        }
        return $this->_lastAddedQuoteItems;
    }
}

I changed it to this (as indicated in Piyush's answer):

<?php
class TM_SuggestPage_Block_Cart extends Mage_Checkout_Block_Cart_Sidebar
{
    protected $_lastAddedQuoteItems = null;
    protected function _prepareLayout()
    {
        if (!Mage::registry('product')) {
            $productId = Mage::getSingleton('checkout/session')->getSuggestpageProductId();
            if (!$productId) {
                return false;
            }
            $product = Mage::getModel('catalog/product')
                ->setStoreId(Mage::app()->getStore()->getId())
                ->load($productId);
            if (!$product->getId()) {
                return false;
            }
            Mage::register('product', $product);
        }
    }
    public function getLastAddedQuoteItems()
{
    $items = Mage::getModel('catalog/category')->load('190')
             ->getProductCollection()
             ->addAttributeToSelect('*')
             ->addAttributeToFilter('status', 1)
             ->addAttributeToFilter('visibility', 4)
             ;
    $this->_lastAddedQuoteItems = $items;

    return $this->_lastAddedQuoteItems;
}
}

But I get the following Error on the website:

Product blah blah was added to your shopping cart.

**

Fatal error: Call to a member function isVisibleInSiteVisibility() on a non-object in /home/myAccount/public_html/app/design/frontend/base/default/template/checkout/cart/sidebar/default.phtml on line 29

**

What am I doing wrong? Please help!

This is line 29 that the Error message is talking about:

$this->_lastAddedQuoteItems = $items;

I tried to mess with the closing tags -

**}**

add or remove some but it does not seem to help!

Edited on January 20th, 2017: My IndexController.php looks like this:

<?php

class TM_SuggestPage_IndexController extends Mage_Core_Controller_Front_Action
{
    public function indexAction()


{

   $this->loadLayout()
    ->_initLayoutMessages('checkout/session')
    ->_initLayoutMessages('catalog/session');


$block2 = $this->getLayout()->createBlock('checkout/cart_coupon')->setTemplate('checkout/cart/coupon.phtml');
$this->getLayout()->getBlock('content')->append($block2);

$_product = Mage::getModel('catalog/product')->load(100); 
$block = $this->getLayout()->createBlock('checkout/cart_crosssell')->setProduct($_product)->setTemplate('checkout/cart/crosssell.phtml'); $this->getLayout()->getBlock('content')->append($block);


$this->renderLayout();
    }
}

Answer 1

As per github url Module provided by you.

You can simply change the product collection of your getLastAddedQuoteItems() function of block.

For category product you can use this code in your Modules Block file Cart.php-

public function getLastAddedQuoteItems()
{
    $items = Mage::getModel('catalog/category')->load('your_category_id')
             ->getProductCollection()
             ->addAttributeToSelect('*')
             ->addAttributeToFilter('status', 1)
             ->addAttributeToFilter('visibility', 4)
             ;
    $this->_lastAddedQuoteItems = $items;

    return $this->_lastAddedQuoteItems;
}

Answer 2

as far as I know add below code in your indexAction That I have given previously

 $this->loadLayout()
    ->_initLayoutMessages('checkout/session')
    ->_initLayoutMessages('catalog/session');

 $category = Mage::getModel('catalog/category')->load(11); //here 11 is category id
 $block    = $this->getLayout()->createBlock('catalog/product_list')->setCategory($category)->setTemplate('catalog/product/list.phtml');
 $this->getLayout()->getBlock('content')->append($block);
 $this->renderLayout(); 

I am not sure but you can try below code to

 $block    = $this->getLayout()->createBlock('catalog/product_list')->setCategoryId(199)->setTemplate('catalog/product/list.phtml'); //here 199 is category Id
 $this->getLayout()->getBlock('content')->append($block);
 $this->renderLayout(); 

EDIT

In your indexController indexAction put below code and remove all other code and here 1 is your product Id so you have to update only 1 product ids cross sell product , that way you can solve your problem and close this question

$this->loadLayout()
    ->_initLayoutMessages('checkout/session')
    ->_initLayoutMessages('catalog/session');


$block2 = $this->getLayout()->createBlock('checkout/cart_coupon')->setTemplate('checkout/cart/coupon.phtml');
$this->getLayout()->getBlock('content')->append($block2);

$_product = Mage::getModel('catalog/product')->load(100); //here 100 is product Id
$block = $this->getLayout()->createBlock('checkout/cart_crosssell')->setProduct($_product)->setTemplate('checkout/cart/crosssell.phtml'); $this->getLayout()->getBlock('content')->append($block);


$this->renderLayout();

Edit 2

$block    = $this->getLayout()->createBlock('catalog/product_list')->setData('category_id',199)->setTemplate('catalog/product/list.phtml'); //here 199 is category Id
 $this->getLayout()->getBlock('content')->append($block);
 $this->renderLayout();
