 To enable pages in framework we need:  A model-Connection to database and represent data on page  A controller- will look up the current page  A template (view)- display data on page to user  With all above, we need some extra information  Menu and Sub menu options  Breadcrumb generation

 Model  Ability to connect to database  Search for a page given by page name/path  Represent data on the page  If no page found, generate “Page not found” error  Can be achieved using a constructor  Pass page path as parameter  Set values to properties if page found  Set particular value if page not found

 We need following methods for page model  isValid(): used by controller to lookup if the page is valid or not?  isActive(): used by controller to lookup if the page is active or not?  isSecure(): used by controller to check if the page is secure or not? And accessible to user or not?  getProperties(): return the properties of the page to integrated with view

 Page view should have following template pages  Header- to have common header on most of the pages  Footer- to have common footer on most of the pages  Page- to display the page to user  We my have additional pages in template  404 Error: indicates page not found  Login: logged in by user to access secure pages  Page Disable: show page is inactive

Header Template It may also contain CSS, JavaScript, Icon etc information

 Footer Template  It may contain copyright info, about us, terms and conditions etc.  Page Template  In case of “Page not found” template

 We may have other templates in framework  Page Disable template  Login Form template  Signup Form template  Shipping Address template  Change password template  Shopping Cart template  And sooooooooooooooo on Can be limited with limited requirements

 Controller of pages needs to perform the following task  Clean the path requested  Pass path to page model  If the page is valid, convert page properties to tags to use in template, output the page view  If the page is invalid, display 404 page  If the page is valid and secure, display the page if user is logged in, else direct user to login page

 We breakdown functionality into 3 areas  Model- manage product data by update, save, clone  Controller- interpret users requests, interface with model, interact with view to display data  Template- to display list of products to end user

 Product model needs the following functionality:  Lookup a product based on a product path  Determine if a product exists or not, based on said path  Store product data  Return product data as an array  Return a Boolean value indicating if a product is valid or not

Product View

 Product Controller needs the following functionality  Needs to communicate with controller  Clean the path requested  Pass product URL path to controller  If a valid product URL, display it using view  If not a valid URL, display “product not found” page

 Our categories functionality of framework will be same as products model and controller with some minor difference  Not as many tables are required to get the category detail, content_version table is enough  Categories need to list products contained within them  We have to deal with child-parent categories structure

 Categories Model  Is complex than other product and pages model because it deals with categories and sub categories  In First stage ▪ Use subqueries, that will count no. of subcategories ▪ Queries are then cached and its references are passed to template or view to display products  In 2 nd Stage ▪ Adding some additional functions in controller about cached queries, if there are any subcategory

 Categories View  We need 3 types of templates to display categories to end user  Category template  Subcategory template  Products Template within category

 Categories View  Category template

 Categories View  Subcategory template

 Categories View  Products template

 Categories Controller  Communicate with Model to get categories  If no category found, show “No Category Found” page  List categories and sub categories using view  If no subcategory found, show “No Subcategory Found” page  List products within categories using views, if any, else show “No Product in Category”

 In our framework, so far, the models, controllers and views of products, categories, pages have same format  Thy can be improved using inheritance in PHP  Common classes can be defined with common functionalities  Product view includes one photo of product  Product view can be changed to mange more photos of products

 First path of the URL should include the area of site that user is trying to access  etc  We need to maintain a list of active controllers  If sitearea match with any active controller  Include controller file, create controller object, pass control to framework controller  Else shows 4o4 page error or “Page not found”

 We need a controller table to save list of active controllers
