The function watermark creates watermark on the image.

Here is the code:

$mainImage = Mage::getBaseDir('media') . DS . 'test' . DS . 'image.jpg';
$watermarkImage = Mage::getBaseDir('media') . DS . 'test' . DS . 'watermark.jpg';

$image = new Varien_Image($mainImage);

// set watermark image width
$image->setWatermarkWidth(100);

// set watermark image height
$image->setWatermarkHeigth(100);

// create watermark image
// watermark($watermarkImage, $positionX=0, $positionY=0, $watermarkImageOpacity=30, $repeat=false)
$image->watermark($watermarkImage);

// save the watermark image
$image->save(Mage::getBaseDir('media'). DS . 'test' . DS . 'new.jpg');

Code Explanation

In the code above, you can see that I have an image named image.jpg inside media/test/ directory.
I have a watermark image named watermark.jpg.
I have set the watermark image width and height to 100px. You can omit these two functions if you don’t want to resize the watermark image.
The new image with watermark is saved inside media/test/ directory as new.jpg.

Hope this helps and thanks for reading.

I googled the web and found the following cause and solution:-

Problem:

I used to have adsense showing in my website and blogs but I use to have adsense showing on my website and blogs but recently they don’t show on websites again instead what i see is this their microfinance stuff “Microfinance Empowers”.

Cause:

Since April 2009 it has been a term of service that Adsense publishers have a data protection compliant privacy policy on their site(s). Those who do not have such a policy often find that their ads turn to public service ads.

Solution:

In your adsense report page, you will see the following text highlighted in red:

Your pages are displaying Public Service Advertisements (PSAs) because you haven’t yet verified your PIN and/or phone number. See the Payment History page for more details.

You should verify your PIN Information in order to show adsense like before.

Login to your adsense account and go to this link: https://www.google.com/adsense/account-settings

You will see the following notification about PIN Information highlighted in red:

As part of our effort to protect the accounts of AdSense publishers, we have mailed a Personal Identification Number (PIN) to the payment address entered in your account. This PIN must be entered on the PIN Information page before any payments can be issued to you.

In the meantime, your account remains active, and you may continue to show ads and accrue earnings. If you have not received your PIN within 3 weeks, you may request that it be resent.

Please use the link below to enter your PIN or to request a reissue:
PIN Information page

Google will mail Personal Identification Number (PIN) to the payment address entered in your account.

You can request PIN from this link: https://www.google.com/adsense/pinentry

Be sure that you have correct Payee information entered. You can edit Payee information from this link: https://www.google.com/adsense/account-edit

The PIN information for your account will be mailed to you by google within 3-6 weeks after your request for PIN.

When you get the PIN card sent to you by Google, you can enter the PIN in the PIN Entry section of this page: https://www.google.com/adsense/pinentry

After that, you can see adsense in your site as before.

Hope this helps and thanks for reading.

Well, the function credit goes to my friend Subesh’s article. He has already written such function in his blog article. I am just re-writing the function with some modifications (Making it easier for me to understand :))

Ok, here is the custom image resize function. This function will resize image proportionally.

/**
 * Resize Image proportionally and return the resized image url
 *
 * @param string $imageName	        name of the image file
 * @param integer|null $width 		resize width
 * @param integer|null $height 		resize height
 * @param string|null $imagePath 	directory path of the image present inside media directory
 * @return string 				full url path of the image
 */
public function resizeImage($imageName, $width=NULL, $height=NULL, $imagePath=NULL)
{
	$imagePath = str_replace("/", DS, $imagePath);
	$imagePathFull = Mage::getBaseDir('media') . DS . $imagePath . DS . $imageName;

	if($width == NULL && $height == NULL) {
		$width = 100;
		$height = 100;
	}
	$resizePath = $width . 'x' . $height;
	$resizePathFull = Mage::getBaseDir('media') . DS . $imagePath . DS . $resizePath . DS . $imageName;

	if (file_exists($imagePathFull) && !file_exists($resizePathFull)) {
		$imageObj = new Varien_Image($imagePathFull);
		$imageObj->constrainOnly(TRUE);
		$imageObj->keepAspectRatio(TRUE);
		$imageObj->resize($width,$height);
		$imageObj->save($resizePathFull);
	}

	$imagePath=str_replace(DS, "/", $imagePath);
	return Mage::getBaseUrl("media") . $imagePath . "/" . $resizePath . "/" . $imageName;
}

You can write the following code in template (.phtml) file to display the resized image:

<img src="<?php echo Mage::helper('moduleName')->resizeImage('abc.jpg', 400, 300, 'xyz/image'); ?>" alt="resized image" />

Here,

$imageName is the name of the image (e.g. abc.jpg)

$width is the image resize width (e.g. 400)
$height is the image resize height (e.g. 300)
(400 resembles 400px and 300 resembles 300px)

$imagePath is the path where the image is stored/saved. This directory must be inside ‘media’ directory. Like, if we specify ‘xyz/image‘ as $imagePath then our image path must be ‘media/xyz/image/abc.jpg‘ (the $imageName is abc.jpg)

We have defined the width and height to be 400 and 300 respectively. So, a new folder will be created named ‘400×300′. The new resized image will be saved here.

If width is null and height is 300 then the image will be resized proportionally with fixed height of 300px. And the folder name will be ‘x300′.

If width is 400 and height is null then the image will be resized proportionally with fixed width of 400px. And the folder name will be ‘400x’.

If both width and height are null then the image is resized with height ‘100′ and width ‘100′. And the folder name will be ‘100×100′.

Cheers,

The following code will show breadcrumbs created by Magento. You can print the following code anywhere in php or phtml files.

echo $this->getLayout()->getBlock('breadcrumbs')->toHtml();

You can create you own breadcrumbs as well. Like, you may need to create breadcrumbs if you have your own custom built module. I will show you here, how you can do it.

It’s simple and easy. At first, you will define the breadcrumbs block. Then, you will add label, title and link to your breadcrumbs. The addCrumb Magento function is used in this case.

$breadcrumbs = $this->getLayout()->getBlock('breadcrumbs');

$breadcrumbs->addCrumb('home', array('label'=>Mage::helper('cms')->__('Home'), 'title'=>Mage::helper('cms')->__('Home Page'), 'link'=>Mage::getBaseUrl()));

$breadcrumbs->addCrumb('country', array('label'=>'Country', 'title'=>'All Countries', 'link'=>'http://example.com/magento/moduleName/country'));

$breadcrumbs->addCrumb('manufacturer', array('label'=>'State', 'title'=>'States'));

The label, title and link can be changed according to your need and requirement.

$fieldset->addField('logo', 'file', array(

	'required'  => false,
	'name'      => 'logo',
));

You can easily upload file using Varien_File_Uploader class. The class file path is lib/Varien/File/Uploader.php.

- In the code below, the file field name is ‘logo‘.
- You can add or remove allowed extension for upload through setAllowedExtensions function.
- If setAllowRenameFiles function’s parameter is set true, then the uploaded file name will be changed if some file with the same name already exists in the destination directory.
- The file is uploaded in media directory. You can add your own directory there. But remember that your directory should be writable.
- save function is used to save the file with a specific name and to a specific path.

if (isset($_FILES['logo']['name']) && $_FILES['logo']['name'] != '') {
	try {
		$uploader = new Varien_File_Uploader('logo');
		$uploader->setAllowedExtensions(array('jpg','jpeg','gif','png'));
		$uploader->setAllowRenameFiles(false);
		$uploader->setFilesDispersion(false);
		$path = Mage::getBaseDir('media') . DS;
		// $path = Mage::getBaseDir('media') . DS . 'logo' . DS;
		$logoName = $_FILES['logo']['name'];
		$uploader->save($path, $logoName);

	} catch (Exception $e) {

	}
}

Hope this helps. Thanks for reading.

We register a variable with register() function.
We can unregister the variable with unregister() function.
To fetch the registry variable, we use registry() function.
We can store anything in the registry variable. It can be integer, string, array, etc.

In the example below, I will be showing you how to create, fetch and destroy registry variable. In other words, I mean how to register, fetch and unregister variables in Magento.

Here, I will be registering store id (integer). The variable key will be ‘store_id‘.

Mage::register('store_id', Mage::app()->getStore()->getId());

Mage::app()->getStore()->getId() gives the current store id.

The key of our newly created variable is ’store_id’. To fetch the newly registered variable, we will use the following code:

Mage::registry('store_id');

We will destroy/unregister the variable when we no longer need it.

Mage::unregister('store_id');

Hope this helps and thanks for reading :-)

Here is the XML code of my config.xml file. I will be reading the nodes of this XML file.

<default>
	<catalog>
		<mypage>
			<name>myname</name>
			<age>100</age>
			<address_one>earth</address_one>
		</mypage>
	</catalog>
</default>

Here is the code to read the node of the above XML file. Here, ‘catalog/mypage‘ is parent nodes path. It depends upon XML node layout.

// prints 'myname'
echo Mage::getConfig()->getNode('catalog/mypage')->name;

// prints '100'
echo Mage::getConfig()->getNode('catalog/mypage')->age;

// prints 'earth'
echo Mage::getConfig()->getNode('catalog/mypage')->address_one;

Hope this helps and thanks for reading.

Here is a sample XML file which I am going to read through Magento code. I will also be adding an XML node to the following XML data.

<?xml version="1.0"?>
<config>
    <modules>
        <MyNamespace_MyModule>
            <version>0.1.0</version>
        </MyNamespace_MyModule>

            <mymodule>
                <use>standard</use>
                <args>
                    <module>MyNamespace_MyModule</module>

                    <file>mymodule.xml</file>
                </mymodule>
            </updates>
        </layout>
    </frontend>
</config>

Here is the Magento/PHP code to read the XML data. I have kept the XML file in the root directory of Magento installation. The XML file is named test.xml. At first, the XML file is loaded and then it’s node are read with getNode function. Then, I have printed the result.

$xmlPath = Mage::getBaseDir().DS.'test.xml';
$xmlObj = new Varien_Simplexml_Config($xmlPath);
$xmlData = $xmlObj->getNode();
echo "<pre>"; print_r($xmlData); echo "</pre>";

You can add node with the setNode function. Here, I have set a node inside the node ‘modules’. The name of my new node is ‘mukesh’ and it’s value is ‘chapagain’.

$xmlObj->setNode('modules/mukesh','chapagain');

Hope this helps. Thanks for reading.
