To include a second type of content,
0:00
the first thing we need to
do is create a pages class.
0:02
Create a new file in source Classes.
0:05
We'll name this Pages.php.
0:08
Our class Pages extends the collection.
0:15
[SOUND] This means that we have two
methods that must be implemented.
0:22
The get title method,
from the collection interface and
0:28
the set entity method,
from the collection class.
0:32
Protected function setEntity.
0:36
This entity equals pages.
0:48
Public function getTitle.
0:56
And then,
since we are always using a single page,
1:04
we can set this method to always
return the current title.
1:08
return $this->current()->title.
1:14
Now we can rename
the index file to blog.php.
1:20
Then we can create a new
file named index.php.
1:29
First, let's add all the required files.
1:41
[SOUND] Require the config.
1:43
[SOUND] Require the view,
1:48
views header.php.
1:53
Require 'views/single.php' and
1:58
require 'views/footer.php';.
2:05
Since we're going to show
pages only as a single item,
2:13
we can use the single.php file.
2:17
Next, we need the content for our page.
2:20
Content equals new pages.
2:28
We'll pass the repo, and
then 1 to find the page.
2:31
Let's take a look at our site now.
2:37
We now see only the welcome page.
2:43
We don't have a way to pull other pages
right now, but, if we type blog.php,
2:46
we can see the blog posts
that we set up earlier.
2:55
Let's add the ability to
pull the rest of our pages.
2:59
We're going to use the slug
field from our page data.
3:02
So we'll set slug equal to home for
our home page.
3:07
Now we can change our initialization
to use the slug variable.
3:12
We'll pass slug, and we also need
to tell it to use the slug field.
3:17
Now we can change the slug variable
based on the page we wish to display.
3:23
Once again, we'll use if is set and
the get variable.
3:29
We'll check for slug.
3:36
And if that's set,
we'll set our slug equal
3:41
to filter_input(INPUT_GET, 'slug',
3:47
and then FILTER_SANITIZE_STRING).
3:53
Let's go back to our site and
see this in action.
4:02
Our home page is still working, and
4:09
if we type ?slug=about-us,
4:13
we can see the About Us page.
4:18
We are almost done.
4:24
To finish our site,
4:25
we need to add some navigation as well
as a featured image to our pages.
