Assignment #1
Introduction to PHP
Goal
Use these starting files. Failure to do so will result in a mark of 0 for this assignment.
Your goal for this assignment is to build a dynamic image gallery using the Unsplash Image Source service. You will be using a PHP data-structure to store the configuration parameters for your gallery.
A working example of this assignment can be seen here: stungeye.com/school/unsplash
File and Folder Structure
Your project requires the following files and folders:
index.php
main.css (Feel free to use the one provided with the example version.)
Folder named images
Unsplash
Unsplash describes itself as: Beautiful, free photos. Gifted by the worlds most generous community of photographers.
Unsplash photos are searchable by keyword on their website. Heres the website search for pastoral goats:
Unsplash also has an API for finding images by keyword using specially constructed URLs.
Locally Saved Unsplash Images
Check out the Unsplash website:
Find and download at least four images that you like.
Make note of the photographers name and the photographers Unsplash URL.
Resize each of these images to be 1230 pixels wide (or a size that suits your CSS).
(In MS Paint: Resize button =>pixel radio button => Horizontal: 1230)
Save these images to your images folder.
Image Gallery Configuration
Your index.php file should be a simple valid HTML5 document with a PHP block at the top. Include the following $config array in this PHP block:
$config =[
'gallery_name' => 'Name of Your Gallery',
'unsplash_categories' =>['array','of','category','keywords'],
'local_images' =>['array','of','local','image','filenames']
];
Update the $config data to customize:
your gallery name
the categories of images you wish to feature (minimum 4)
the filenames of the images you saved earlier (minimum 4)
The rest of your script will use these configuration values.
Gallery Requirements
Your gallery should include the following:
The name of your gallery from the $config data should be displayed at the top of the page in an h1 element.
One image for each of your categories should be displayed.
(Details on loading images by category using the Unsplash API are below. )
Above each image, the name of the category within an h2 element.
A h1 element that reads # Large Images where # is the size of the array of local images with the $config hash. (Use PHP code to find this value.)
The local images you saved to your images folder.
IMPORTANT: You should be using loops to display all your images instead of hardcoding your image tags. Adding new categories or images should not require any changes to your code beyond the $config variable.
Random Unsplash Images by Category
You can load up a random image from Unsplash from a specific category by using cleverly crafted URLs.
Loading a random 300x200 pixel nature photo:
Photographer Name Links
After all of the above is working:
For each of your local images display the name of the photographer.
The name of display should also link to the photographers Unsplash home page.
IMPORTANT: You need to figure out a way to store the photographers name and URL along with the image filenames in the $config variable. Use your knowledge of arrays and hashes to figure out how best to store this information.
Open the example version of this assignment to see what this photographer attribution might look like.
Remember, adding new images to your page should not require any changes to your code beyond the $config variable.
Wizard Tutorial - Javascript Responsive Lightbox (Optional)
A javascript lightbox allows us to view full-size images by clicking on image thumbnails.
Here's what you'll be building. (Click on any of the small images.)
Lets create a lightbox gallery using the Luminous Javascript library:
Make a copy of your working index.php file. Call this copy: lightbox.php
Modify lightbox.php to only display your locally stored images.
Remove the links to the photographers Unsplash pages.
Make thumbnail versions of all your images that are 300 pixel wide. Name each thumbnail with _thumbnail at the end of the filename.
Example: mountain.jpg becomes mountain_thumbnail.jpg.
Modify each image such that the thumbnail displayed within a link to the fullsize image. For example:
Add these CDN-served link and script tags to your HTML head element:
