Magento Show Poll Results

Add this code in order to show the poll results in de poll block (using this article):

In addition for the result add in poll.phtml:

if ($poll->isVoted($poll->getId()) == TRUE) {
//Template Block
echo $this->getLayout()->createBlock(‘core/template’)->setTemplate(‘poll/result.phtml’)->setAttribute(‘my_poll_id’, $poll->getId())->toHtml();
} else {

// add the rest of the poll script here

}

Further open results.phtml and add on top:

if(!isset($poll)) {
$poll = new Mage_Poll_Model_Poll();
$poll->load($this->my_poll_id);

$action = Mage::getUrl(‘poll/vote/add’, array(‘poll_id’ => $poll->getId()));

$poll_answers = Mage::getModel(‘poll/poll_answer’)
->getResourceCollection()
->addPollFilter($poll->getId())
->load()
->countPercent($poll);

}

This should do the trick!

Lesti::Fpc and Layered Navigation

Lesti::Fpc is a great free Full Page Cache plugin for Magento. Though, it could be that it doesn’t work with Layered Navigation.

Solution

1. Go to your site and layered navigation and hover with your mouse on a filter item. It shows the url parameters (like ?color=red&manufacturer=brand).

2. Those parameter you need to add in the admin > config > system > Lesti::FPC > URL params. There add all the possible parameters from above. Like:

price,
cat,
manufacturer,
no_cache,
color

 

Magento import multiple images in dataflow csv/xml

Sometimes it’s really annoying that Magento only supports one image per product. On the Magento Commerce forum a solution is found:

Now, what you need to do is open the file
app/code/core/Mage/Catalog/Model/Convert/Adapter/Product.php
and go to around line 773 and find

$addedFilesCorrespondence = $mediaGalleryBackendModel->addImagesWithDifferentMediaAttributes(
$product,
$arrayToMassAdd, Mage::getBaseDir('media') . DS . 'import',
false,
false
);

and paste the following code right after it
if (isset($importData['media_gallery']) && !empty($importData['media_gallery'])) {
$x = explode(',', $importData['media_gallery']);
foreach ($x as $file) {
$imagesToAdd[] = array('file' => trim($file));
}
$mediaGalleryBackendModel->addImagesWithDifferentMediaAttributes(
$product,
$imagesToAdd, Mage::getBaseDir('media') . DS . 'import',
false,
false
);
}

Magento place order slow [FIXED]

The Magento “place order” step can take up to a minute. With thanks to this site I figured out how to fix slow checkouts.

Step 1

Find the file app/code/core/Mage/Rss/etc/config.xml and uncomment/remove:

<sales_order_save_after>
<observers>
<notifystock>
<class>rss/observer</class>
<method>salesOrderItemSaveAfterNotifyStock</method>
</notifystock>
</observers>
</sales_order_save_after>
<sales_order_save_after>
<observers>
<ordernew>
<class>rss/observer</class>
<method>salesOrderItemSaveAfterOrderNew</method>
</ordernew>
</observers>
</sales_order_save_after>

Step 2

Find the file app/code/core/Mage/Downloadable/etc/config.xml and uncomment/remove:

<!–sales_order_item_save_commit_after>
<observers>
<downloadable_observer>
<class>downloadable/observer</class>
<method>saveDownloadableOrderItem</method>
</downloadable_observer>
</observers>
</sales_order_item_save_commit_after–>

sqlstate 23000 integrity constraint violation 1048 column ‘value’ cannot be null magento

How to solve the problem ‘sqlstate 23000 integrity constraint violation 1048 column ‘value’ cannot be null magento’?

This problem is quite hard to identificate, because it’s hard to seek the right column ‘value’. Here is what I did in order to find out the problem.

  • Start the import process and see on which record number the errors occur.
  • Locate these record numbers and find the difference between other records in a spreadsheet program.
  • In my example I found out that on some rows the meta_robots column was empty instead of INDEX, FOLLOW. This caused the error.
  • Fill these rows. This will solve the problem.

BTW verhoging 21 procent doorvoeren in Magento (dutch)

Het kan de meeste mensen inmiddels niet ontgaan zijn, per 1 oktober 2012 zal er een BTW verhoging ingaan van 19 naar 21 procent. Vervelend daarbij is dat er nogal wat onduidelijkheden zijn. Aangezien ik zelf verstand heb van het webwinkel pakket Magento, probeer ik in dit artikel alle onduidelijkheden omtrent het nieuwe BTW tarief de wereld uit te helpen. U kunt daarbij zelf kiezen of u de BTW in de prijs door wilt voeren liever niet.

Stap 1: BTW tarief verhogen

Dit kunt u doen bij Verkopen > BTW > Beheer Belastingzones en Tarieven

Stap 2a: BTW in de prijs door laten voeren (prijsverhoging)

Hier komt een technisch verhaal bij kijken. De bedoeling is dat de catalogusprijs met de stijging van het btw-niveau automatisch meegaat. Uitgerekend is dit een prijsstijging van 1,68% (aan de hand van (1/119)*121*100% ). De bedoeling is dus om een negatieve korting te geven op alle producten.

Magento accepteert echter standaard geen negatieve kortingen:

Magento Negatieve Korting

 

 

Conform het volgende artikel moeten we dus een paar wijzigingen doorvoeren in de kern:

  1. Ga naar: app/code/core/Mage/Rule/Model/Rule.php en vind:
    //check if discount amount > 0
    if ((int)$this->getDiscountAmount() < 0) { 3 Mage::throwException(Mage::helper(‘rule’)->__(‘Invalid discount amount.’));
    }
  2. Vervang deze code door deze uit te 'commenten':
    // if ((int)$this->getDiscountAmount() < 0) { 3 //Mage::throwException(Mage::helper(‘rule’)->__(‘Invalid discount //amount.’));
    //}
  3. Ga nu naar: app/code/core/Mage/Adminhtml/Block/Promo/Quote/Edit/Tab/Actions.php en vind: 'class' => 'validate-not-negative-number',
  4. ‘Comment’ deze code ook uit: // 'class' => 'validate-not-negative-number',
  5. Herhaal stap 3 en 4 voor het bestand app/code/core/Mage/Adminhtml/Block/Promo/Catalog/Edit/Tab/Actions.php
  6. Verander in het bestand app/code/local/Mage/CatalogRule/Model/Observer.php :
    $finalPrice = min($product->getData(‘final_price’), $this->_rulePrices[$key]);
    in:
    $finalPrice = $this->_rulePrices[$key];
  7. Vervolgens kunt u deze bestanden uploaden (het veiligste is om de bestanden niet in app/code/core, maar app/code/local op te slaan).
Vervolgens kunt u de negatieve korting doorvoeren.
Ga naar promotie > catalogus prijsregels > nieuwe regel aanmaken. Geef de prijsregel een naam en voer bij actie het tarief van -1,68 procent in. Daarbij kunt u een vanaf datum van 1 oktober 2012 instellen. Vervolgens kunt u de wijzigingen opslaan en klikt u op ‘apply rules’.
Het nadeel van een automatische stijging is wel dat een ‘mooie’ prijs als €49,95 zal vanderen in €55,21. Mocht u later dus alle prijzen handmatig wijzigen, kunt u de zojuist ingevoerde prijsregel weer uitzetten.

Stap 2b: BTW niet in de prijs door laten voeren (gelijke prijs)

Als het goed is, is hier verder geen wijziging voor nodig.

Extra fee for Shopping Cart AND Catalog Cart Price Rules in Magento – Negative discount

This article is incomplete and the solution might not work!

Ever wondered wether it would be possible creating a negative discount? This article describes how to create a negative shopping cart price rule.

By default, Magento doesn’t accept negative price rule discount values:

Magento Negatieve Korting

We have to add some changes through the core in Magento conform the article:

  1. Go to: app/code/core/Mage/Rule/Model/Rule.php and fin:
    //check if discount amount > 0
    if ((int)$this->getDiscountAmount() < 0) { 3 Mage::throwException(Mage::helper(‘rule’)->__(‘Invalid discount amount.’));
    }
  2. Replace this code, by 'commenting':
    // if ((int)$this->getDiscountAmount() < 0) { 3 //Mage::throwException(Mage::helper(‘rule’)->__(‘Invalid discount //amount.’));
    //}
  3. Go to: app/code/core/Mage/Adminhtml/Block/Promo/Quote/Edit/Tab and find: 'class' => 'validate-not-negative-number',
  4. ‘Comment’ this code as well: // 'class' => 'validate-not-negative-number',
Now it works for shopping cart price rules. Unfortunately the article doesn’t describe how to enable negative values for catalog price rules. We have the solution:
  1. Repeat step 3 and 4 for the file app/code/core/Mage/Adminhtml/Block/Promo/Catalog/Edit/Tab/Action.php
  2. Then you can upload these files, I’ll prefer to save it in the app/code/local directory instead of core.

Serialization failure: 1213 Deadlock found when trying to get lock; try restarting transaction

When having trouble with the error: “Serialization failure: 1213 Deadlock found when trying to get lock; try restarting transaction” or when your place order / order confirmation gets stuck.

Fixing the order process getting stuck:

According to the Magento Forum, in MySQL, try:

TRUNCATE `log_customer`;
TRUNCATE `log_quote`;
TRUNCATE `log_summary`;
TRUNCATE `log_summary_type`;
TRUNCATE `log_url`;
TRUNCATE `log_url_info`;
TRUNCATE `log_visitor`;
TRUNCATE `log_visitor_info`;

Of course create a backup first. Doesn’t this fix the problem or do you have a better solution? Comment it!

Change the ‘add to cart’ button to ‘view product’ in Magento on category page

So you’ve got your webshop with products with different sizes. The ‘add to cart’ button on the category page is sometimes a step too much, because you’ll have to choose a size first.

Changing the button to ‘view product’

Changing the button to ‘view product’ would be a better solution. Open the file list.phtml in: /app/design/frontend/default/{yourskin}/template/catalog/product .

About line 63 and about line 107 replace: <p><button type=”button” title=”<?php echo $this->__(‘Add to Cart’) ?>” onclick=”setLocation(‘<?php echo $this->getAddToCartUrl($_product) ?>’)”><span><span><?php echo $this->__(‘Add to Cart’) ?></span></span></button></p>

With:

<button type=”button” title=”<?php echo $this->__(‘Add to Cart’) ?>” onclick=”setLocation(‘<?php echo $_product->getProductUrl() ?>’)”><span><span>View product</span></span></button>
