  1. I can only see the need for 2 tables. A documents table and a document_types table. The documents table references the documents_type table by type_id I.e. documents ---------- doc_id type_id date_added doc_name document_types ---------- type_id type_title document_types would contain people, companies, and projects, and any other types. Each has an id and is used in a join from documents when you want to say fetch all company documents. You do not want to be creating separate tables for each type as there is no flexibility in the design and as you have already found out it is hard to create the business logic.
  2. Here's a challenge for anyone using OOP so you can see how it benefits. I've started it off and you can see there are issues that need to be corrected. An online shop needs an order dispatch system for sending out parcels using different couriers. At the start of the day a batch will be started and at the end of the day it will be closed when no more parcels are going to be shipped. This is called the dispatch period. Each parcel sent out with a courier is called a consignment. Each consignment will be given a unique number and each courier will provide an algorithm for generating the number. At the end of the dispatch period a list of all consignment numbers need to be sent to each courier. Each courier has their own method for accepting the list i.e. UPS uses email, Fedex uses FTP. Build a structure using OOP to facilitate the implementation of the above scenario. It does not need to be a final product. Assume that your library is given to another developer to use who will build a front end for it that will have the following features: 1. Start a new batch 2. Add a consignment 3. End the batch /** * Interface CourierInterface */ interface CourierInterface { /** * Fetch a consignment number * @return int */ public function fetchConsignmentNumber(); /** * Dispatch a consignment number to a courier */ public function dispatch($number); } class FedexCourier implements CourierInterface { /** * @var int */ private static $count = 10000; /** * We will use a simple static counter here to return a number * @return int */ public function fetchConsignmentNumber() { self::$count++; return self::$count; } /** * Send to courier * @param $number * @return string */ public function dispatch($number) { } } class Consignment { /** * @var CourierInterface */ protected $courier; /** * @var int $number Should contain a consignment number */ protected $number; /** * Consignment constructor. * @param CourierInterface $courier */ public function __construct(CourierInterface $courier) { $this->courier = $courier; // fetch a consignment number from the courier $this->number = $this->courier->fetchConsignmentNumber(); } /** * Simple getter * @return int */ public function getNumber() { return $this->number; } /** * @return mixed */ public function process() { return $this->courier->dispatch($this->number); } } class Batch { /** * @var array */ protected $consignments = []; /** * Batch constructor. * Start the dispatch period * This could take in a storage dependency for persistence */ public function __construct() { } /** * Add a consignment to the current batch * * @param Consignment $consignment */ public function addConsignment(Consignment $consignment) { $this->consignments[] = $consignment; } /** * Process each consignment */ public function endDispatchPeriod() { // loop through each of the consignments // the storage dependency could be use here to track the consignment numbers // i.e. $c->getNumber() foreach ($this->consignments as $c) { $c->process(); } } } Client <?php // client code // start a new batch $batch = new Batch(); // add some consignments $parcel1 = new Consignment(new FedexCourier()); $batch->addConsignment($parcel1); $parcel2 = new Consignment(new FedexCourier()); $batch->addConsignment($parcel2); // end the batch $batch->endDispatchPeriod(); ?>
  3. 1. Remove any PHP / Server Side code 2. Strip out any <img> tags 3. Strip out any <script> tags 4. Strip out any <link> tags to CSS files Job done. Should run like lightning!
  4. Also consider Yii http://www.yiiframework.com/
  5. For dedicated servers I would like to add OVH http://www.ovh.co.uk/products/dedicated_offers.xml We have about 5 of these servers running CentOS.
  6. Keldorn, this is for you [attachment deleted by admin]
  7. Trialing DWCS4. Couldn't get used to netbeans. Happy so far. The code colouring is far better than any other IDE. Too much customising in netbeans.
