Question & Answers

2. What is wishlist in shopping cart

Ans:- When you select a product to shopping cart a product from inventory is subtracted and a that product is added to your cart where in wishlist it doesn't happen.

Other use: When you find some cool thing you wish to buy after you get your salary you drop it into wishlist, E-commerce companies use this to sent customized offers to users. A win-win game.  

Amazon recently came up with amazing idea as you can check your friends wishlist and gift him on occasion. so you give the best gift for your buddy.

3. How to connect to database in joomla
Ans :- If you need to access tables within the same database as your Joomla! installation then you can simply use the JFactory->getDbo method. This uses the already established connection that Joomla! uses to connect to the database. For example:

<?php
$db = JFactory::getDbo();
?>

$db is now an object of type JDatabaseDriver and you can perform database operations on it using the usual methods.

But what if you want to connect to a completely different database from the one used by Joomla!?. This might be a different database on the same machine as your Joomla! site or it might be on a different host and perhaps even require a different database driver. Well, you can do this using the JDatabaseDriver->getInstance method.

<?php
$option = array(); //prevent problems
 
$option['driver']   = 'mysql';            // Database driver name
$option['host']     = 'db.myhost.com';    // Database host name
$option['user']     = 'fredbloggs';       // User for database authentication
$option['password'] = 's9(39s£h[%dkFd';   // Password for database authentication
$option['database'] = 'bigdatabase';      // Database name
$option['prefix']   = 'abc_';             // Database prefix (may be empty)
 
$db = JDatabaseDriver::getInstance( $option );
?>

$db is now an object of type JDatabaseDriver and you can perform database operations on it using the usual methods.

5. What is page template in wordpress
Ans:- Since a page template is a specific type of template file, here are some distinguishing features of page templates: Page templates only apply to pages, not to any other content type (like posts and custom post types). Page templates are used to change the look and feel of a page.

• Page templates only apply to pages, not to any other content type (like posts and custom post types).
• Page templates are used to change the look and feel of a page.
• A page template can be applied to a single page, a page section, or a class of pages.
• Page templates generally have a high level of specificity, targeting an individual page or group of pages. For example, a page template named page-about.php is more specific than the template files page.php or index.php as it will only affect a page with the slug of “about.”
• If a page template has a template name, WordPress users editing the page have control over what template will be used to render the page.
