/**Using the Previously created DB**/
mysql> use magento

/**Import the Dumpped SQL**/
mysql>source pathToMagentoRoot/mySql.sql

So after the command is executed I had the whole DB on production enviornment. Similarly we can also import dumpped data of Production on Local database running on WAMP server.
To import Dumpped SQL data on WAMP, first create a database, say magento and then use the following commands

/**
	Using the Previously created DB.
	-p password part is optional if you have not configured password for MYSQL locally
	-u Username (root by default)
**/

mysql> C:\wamp\bin\mysql\mysql5.0.51b\bin>mysql.exe -use magento -u root -p password

/**Import the Dumpped SQL**/
mysql>source pathToSQLSource/mySql.sql

By Now we have the database synced between Local and Production. Next is configuring the database name used by Magento. Browse to app/etc/local.xml and change in the following part.

    <connection>
                    <host><![CDATA[localhost]]></host>
                    <username><![CDATA[username_here]]></username>
                    <password><![CDATA[password_here]]></password>
                    <dbname><![CDATA[databasename_here]]></dbname>
                    <active>1</active>
    </connection>

Finally, browsed through table core_config_data and find value of path: web/unsecure/base_url and path: web/secure/base_url and change their values accordingly.

Now I had my Shop enviorment switched. Most work for you as well. LOL.

Here is the function.

/**
	 * @param $value - Must be comma seperated options.
	 * @param $title - Title of the custom option.
	 * @param $type - Type of custom option - drop_down,radio,checkbox,multiple,area,field.
	 * @param $noOption - Specifies if the custom options has options or not.
	 */
	function setCustomOption ($value, $title, $type, $noOption = false)
	{
		$custom_options = array();
		if ($type && $value != "" && $value) {
			$values = explode(',', $value);
			if (count($values)) {
				/**If the custom option has options*/
				if (! $noOption) {
					$is_required = 0;
					$sort_order = 0;
					$custom_options[] = array(
						'is_delete' => 0 , 'title' => $title , 'previous_group' => '' , 'previous_type' => '' , 'type' => $type , 'is_require' => $is_required , 'sort_order' => $sort_order , 'values' => array()
					);
					foreach ($values as $v) {
						$titleopt = ucfirst(trim($v));
						switch ($type) {
							case 'drop_down':
							case 'radio':
							case 'checkbox':
							case 'multiple':
							default:
								$title = ucfirst(trim($v));
								$custom_options[count($custom_options) - 1]['values'][] = array(
									'is_delete' => 0 , 'title' => $titleopt , 'option_type_id' => - 1 , 'price_type' => '' , 'price' => '' , 'sku' => '' , 'sort_order' => ''
								);
							break;
						}
					}
					return $custom_options;
				}
				/**If the custom option doesn't have options | Case: area and field*/
				else {
					$is_required = 0;
					$sort_order = '';
					$custom_options[] = array(
						"is_delete" => 0 , "title" => $title , "previous_group" => "text" , "price_type" => 'fixed' , "price" => '' , "type" => $type , "is_required" => $is_required
					);
					return $custom_options;
				}
			}
		}
		return false;
	}

And to save the custom option, first get the array built by the above function and pass it to the catalog/product_option Model’s function to save. Here’s how you do it.

$arrayOption = array();
	/**
	 * For Creating dropdown,select,multiselect,radio type of custom option
	 */
	$arrayOption[] = setCustomOption("OPT1,OPT2", "Select Option", "drop_down");
	/**
	 * For Creating textfield and textarea type of custom option
	 */
	$arrayOption[] = setCustomOption("Anyvalue", "Area", "area", true);
	/**
	 * Load the product you want to assign custom option to
	 */
	$product = Mage::getModel("catalog/product")->load(167);
	foreach ($arrayOption as $options) {
		foreach ($options as $option) {
			$opt = Mage::getModel('catalog/product_option');
			$opt->setProduct($product);
			$opt->addOption($option);
			$opt->saveOptions();
		}
	}

After running the code you will get something like this.

Custom Option added to a Product

Hope you like this post!

Here’s the code to get the all the custom options of a product. Please see that you need to specify the id of the product for which you are retriving custom option for. I’ve echoed some text as well to give you an idea what exactly you are getting in each loop.

$product = Mage::getModel("catalog/product")->load(167);
	$i = 1;

	echo "<pre>";

	foreach ($product->getOptions() as $o) {

		echo "<strong>Custom Option:" . $i . "</strong><br/>";
		echo "Custom Option TYPE: " . $o->getType() . "<br/>";
		echo "Custom Option TITLE: " . $o->getTitle() . "<br/>";
		echo "Custom Option Values: <br/>";

		// Getting Values if it has option values, case of select,dropdown,radio,multiselect

		$values = $o->getValues();
		foreach ($values as $v) {

				print_r($v->getData());
		}

		$i++;

		echo "----------------------------------<br/>";
	}

Happy coding in Magento!
