Creating users to use MySQL and Changing Root Password in Linux debian

2011-04-11T07:50:00.001-07:00

By default mysql creates user as root and runs with no passport. You might need to change the root password.

To change Root Password
= mysql -u root
mysql> USE mysql;
mysql> UPDATE user SET Password=PASSWORD('new-password') WHERE user='root';
mysql> FLUSH PRIVILEGES;

Storing variable or other data using pear cache

2011-02-04T22:21:00.000-08:00

You can do this by using the base cache class:


require_once(“Cache.php”);

$cache = new Cache(“file”, array(“cache_dir” => “cache/”) );
$id = $cache->generateID(“this is a unique key”);

if ($data = $cache->get($id)) {

print “Cache hit.
Data: $data”;

} else {

$data = “The quality of mercy is not strained…”;
$cache->save($id, $data, $expires = 60);
print “Cache miss.
”;

}

To save the data we use save(). If your unique key is already a legal file name, you can bypass the generateID() step. Objects and arrays can be saved because save() will serialize the data for you. The last parameter controls when the data expires; this can be the seconds to cache the data, or a Unix integer timestamp giving the date and time to expire the data, or zero to use the default of 24 hours. To retrieve the cached data we use get().

You can delete a cached data item using $cache->delete($id) and remove all cached items using $cache->flush().

New: A faster Caching class is Cache-Lite. Highly recommended.

How to create a custom maintenance page in magento?

2010-06-02T09:13:00.000-07:00

New Magento 1.4 brings changes in how errors are displayed along with an easy way to put your favorite store into maintenance mode.

If you check index.php file of new Magento 1.4, you’ll notice one interesting thingy, it checks for existence of “maintenance.flag” file in store root, if it’s found your store is put into maintenance mode. Service Temporarily Unavailable page is displayed with Please try again later message. Remember that administration can’t be accessed in maintenance mode along with the store.

Developers probably noticed that errors also are no longer displayed like before, as mentioned on Magento blog:
Since version 1.4.0.0 for security reasons the trace in the Magento error report page is disabled by default. The “Error log number” does not give any information about the error. To enable the trace copy the errors/local.xml.sample to errors/local.xml and follow the instructions described in that file.

By default, error logs are placed in /var/report, named by mentioned log number. local.xml file is well commented, so open it and check possible configuration options. I really like emailing of error reports to specified email address.

If you want to change default maintenance look, you can change myskin value in /errors/local.xml file and create new /errors/myskin folder based on /errors/default. It functions the similar way as themes, if the phtml file isn’t found in your skin, the default will be used.

How to add featured products to homepage in magento

2010-06-01T07:54:00.000-07:00

====== Add Featured Products to Home Page ======

- Create a category to contain the featured products. Call it e.g. "Featured" or "Home Page". Set "Is Active" to No. That way, it won't display in the catalog menu.
- After saving the category, please note what ID it gets. You can see it in the last part of the URL. If the URL ends with ''catalog_category/edit/id/8/'', the ID is 8. On later version, the ID is next to the category name:{{how_to:categoryid.png?625}}
- Add products for the home page to the new category.
- Edit the Home Page (CMS -> Manage Pages -> Home Page) and add the following content, where 8 should be replaced by your category ID:

{{block type="catalog/product_list" category_id="8" template="catalog/product/list.phtml"}}

{{how_to:notice.png}} If your product/list.html references $this->getColumnCount() you can vary the column count (e.g. 4 columns) from the default (3) displayed by using:

{{block type="catalog/product_list" column_count="4" category_id="8" template="catalog/product/list.phtml"}}

Although displaying more than 3 columns in your template would likely require additional CSS/layout changes as well.

If you want a view that is different from the category lists, you can copy and modify list.phtml and change the path above. Following steps is an example.

==== Add Bestsellers to Home Page using the best-selling box of Blue Theme ====
In Blue Theme, there is a sample HTML code in the content box (Admin -> CMS -> Manage Pages -> Home Page) that displays a list of Best Selling Products. You can easily modify list.phtml to reuse the skin of the best-selling box. Adding featured products to Home Page is a matter of clicking to select the required products in the category (Admin -> CMS -> Manage Categories -> Category Products tab) as outlined in the above method and there is no need to mess with the HTML code in the CMS.

- Copy the following code to your preferred text editor

getLoadedProductCollection() ?>
count()): ?>

__('There are no products matching the selection.') ?>
count() ?>


                      







htmlEscape($_product->getName()) ?>

getPriceHtml($_product, true) ?>

getRatingSummary()): ?>

getReviewsSummaryHtml($_product, 'short') ?>



getShortDescription()) ?>

__('Learn More') ?>                   
 
 
count() ?>

- Name it homelist.phtml and save it in location ''app/design/frontend/default/blue/template/catalog/product'', create the folders where necessary
- Edit the Home Page (CMS -> Manage Pages -> Home Page) and add the following content, where 19 should be replaced by your category ID:

Best Selling Products

{{block type="catalog/product_list" category_id="19" template="catalog/product/homelist.phtml"}}

**Please note:** In order to make this work for more than one block of products with different category IDs on the same page, you need to add the following code at the end of your phtml file(s):

===== Alternative way: =====
If you are on 1.4 or greater or 1.7EE or greater then this post is no longer valid as magento has moved to using widgets. You can find a featured product widget here: http://www.magewidgets.com/featured-products-widget.html

If you want more in depth way, try to view this post:
http://inchoo.net/ecommerce/magento/featured-products-on-magento-frontpage/

If you're using Magento v1.1.5 or later, you might want to use these code snippets instead:
http://www.magentocommerce.com/boards/viewthread/4780/P15/#t44262
This approach uses core functions instead of using Zend DB to figure out how to build a query statement.
