Part IV: Customizing and Extending the System 612 11. If you want to add the sample data, click the Install Sample Data button, or click the Go Directly to Shop button. The component populates the database accordingly and then takes you to the Store control panel where it displays a confirmation message. 12. Access your Joomla! database installation; typically this is done through phpMyAdmin. 13. Import into your database the file virtuemart.installation.addons.joomla1.5.sql, which is located inside the /administration/components/com_virtuemart/ sql directory. If successful, you see a confirmation message. 14. Access the Module Manager by selecting the option Module Manager under the Extensions menu. The Module Manager loads in your browser. 15. Enable all VirtueMart modules. 16. Access the Plugins Manager by selecting the option Plugin Manager under the Extensions menu. The Plugin Manager loads in your browser. 17. Enable all VirtueMart Plugins. The installation process is now complete and you should be able to access all the features of VirtueMart. Reviewing the VirtueMart Control Panel When you access the VirtueMart component you will first see the default VirtueMart control panel, as shown in Figure 23.4. The control panel is intended to give you quick access to the most com- mon functionalities needed by a shop administrator. Note at the top left, above the VirtueMart logo, two texts links labeled Simple Layout and Extended Layout. The default view is the Simple Layout. Clicking the Extended Layout link radically changes the interface, as shown in Figure 23.5. If you are doing extensive work on the Shop, you are likely find the Extended Layout to be more usable. Keep in mind that the Extended Layout is geared toward administratrators and the simple layout is the layout you would probably want to display to your users who prefer a less cluttered interface.

Configuring VirtueMart Immediately after installation you can configure the Shop to suite your needs. Configuration is a lengthy process and can be time-consuming, particularly if you have not yet thought through the options you want to use for your Shop. Note that the decisions you make during the initial config- uration can be modified at a later time. To begin, click the Configuration icon on the VirtueMart Control Panel. Global Store configuration The Global Store configuration opens to display a set of seven tabs: l Global l Security l Site Chapter 23: Implementing e-Commerce with VirtueMart 615 l Shipping l Checkout l Downloads l Feed Configuration Each tab is discussed in detail in the following sections. Global tab Clicking the Configuration icon on the VirtueMart control panel displays the Configuration screen. The default tab displayed is the Global tab, as shown in Figure 23.6. The Global tab’s workspace is divided into seven areas: l Global l Price Configuration l Frontend Features l Tax Configuration l User Registration Settings l Core Settings l Logfile Configuration The Global area includes the following options: l Shop is offline?: Check this box to take the Shop offline. This causes the message entered in the parameter immediately below to be displayed to visitors who click on the link to the Shop. Note that this is does not take the entire site offline, just the Shop portion of the site. If you want to take the entire site offline, use the controls in Joomla’s Global Configuration Manager. Cross-Reference Joomla!’s Global Configuration Manager is discussed in Chapter 4. l Offline Message: Enter into this text field the message you want visitors to see when the Shop is offline. This is only visible when the parameter immediately above is checked. l Use only as catalogue: Check this box to disable all shopping cart functionalities. (for example, add to cart and buy now buttons.) Part IV: Customizing and Extending the System 616 FIGURE 23.6 The Global tab of the Configuration Manager. Chapter 23: Implementing e-Commerce with VirtueMart 617 The Price Configuration area includes the following options: l Show Prices: Check this box to show prices with the products. l Member group to show prices to: If you want to only show prices to certain groups of users, select them here. To show the price information to all visitors, select Public Front-end. l Show “(including XX% tax)” when applicable?: If your prices include tax (that is, tax is not extra), then check this box to show users the text “including xx% tax” alongside the price information for the product. l Show the price label for packaging?: Use this when products are sold in multiples of units and the pricing is based upon the purchase of a set package of units. The Frontend Features area includes the following options: l Enable content mambots / plugins in descriptions?: Allows the Joomla! system plugins to parse the content of the product descriptions. This is useful for providing dynamic con- tent in the product or category descriptions.

This allows customers to fill in coupon numbers to get discounts on products. l Enable Customer Review/Rating System: Check this box to enable User Reviews and Ratings of Products. l Auto-Publish Reviews?: Check this box to publish automatically any user reviews with- out requiring prior administrator approval. l Comment Minimum Length: The minimum required number of characters for a valid comment. l Comment Maximum Length: The maximum number of characters for a valid comment. l Enable Affiliate Program?: Check this box to enable affiliate tracking on the front end.

By default there is only one, convertECB, which fetches the data for the cur- rency converter from the European Central Bank. Note The currency converter module is only needed if you offer shoppers their choice of currencies. The currencies option is set in the Store Information panel, which is accessed by clicking on the sub-menu Edit Store under the Store menu. l Order mail format: Select either HTML or text only e-mails format for e-mails sent by the system. l DEBUG?: Check to enable Debugging. Note this will cause debugging info to be dis- played at the bottom of pages.

Chapter 23: Implementing e-Commerce with VirtueMart 621 The Security tab’s workspace is divided into three areas: l Security Settings l More Core Settings l Global Proxy Settings The Security Settings area includes the following options: l Site URL: This field should show the site URL that resulted from the installation process. You can alter this if necessary, but an incorrect value will cause problems! l SECUREURL: Enter the secure URL to be used for the site (https). l Shop areas which must use https: Select from the combo box one or more areas of the site that must use secure https protocol. l Generally prevent https connections?: When checked, the system will steer the user out of https URLs when the visitor is viewing pages where https is not needed. This improves site performance. l Encryption Function: If you want to use encryption on the site, select AES_ENCRYPT. l Encryption Key: System-created encryption key. It is generally not necessary for you to change this value. l Store Credit Card Information: Check if you want the system to store the users’ credit card information in the database. This will be encrypted, but you should not select this option if you do not need the data. l Allow Frontend-Administration for non-Backend Users?: Check if you want to allow any of the front-end registered user groups to manage the shop. Do not select this if you do not intend to allow this level of access to the Shop. The More Core Settings area includes the following options: l Table Prefix for Shop Tables: The default value for the database table prefix is vm. Changing this value can crash your site, so do not do this unless you know what you are doing! l HOMEPAGE: The Shop’s default home page. Typically you do not want to alter this unless you have created a special home page. l ERRORPAGE: The Shop’s error page. Typically you do not want to alter this unless you have created a special error page. The Security Settings area includes the following options: l URL of the proxy server: This value will be used by the Shop server to connect to the Internet when needed. Typically this field is left blank as this will be handled automati- cally by your server. l Proxy Port: The port used for the connection with the proxy server. Typically this field is left blank as this will be handled automatically by your server.
