Building the Back-End of a Photo Site

by

For those of you who have been following the last few screencasts, you must have noticed that each tutorial has been centered around a "photo site" theme. (See Scanning Folders With PHP, How to Dynamically Create Thumbnails, and Create a Photo-Admin Site Using PHP and jQuery. Today, we'll build the backend for a photo site. This tutorial will teach you how to add, delete, and update photos.

Our Mission

  • Create a database that will store our images.
  • Create a home page that retrieves all of the photos that are stored in our database.
  • Allow the user to upload photos.
  • Write some validation to ensure that the user enters a proper description and chooses an image
  • Use jQuery to allow the user to asynchronously update and delete specific photos.

There is simply too much to cover as a written tutorial. I've included a few key points. Refer to the screencast for the complete tutorial.

So that does it. You could implement a bit more security into this application. But the idea is that these pages would already be secured by using something similar to an ht-access file. From here on, the sky is the limit. You should consider adding tags to your images, creating albums, etc. This should get you started.
