Single post
Our blog is almost ready, however, there is still one important part missing. We can display all of our posts in a loop, but when someone tries to read the entire post it doesn't work. In order to let users read the entire content, we have to create a new file which will be responsible for displaying single posts. Let's do it!
1. HTML markup
- Create a file called
single.php. - Paste in the following code and save the file:
- Open your blog and click into one of your posts. It will redirect you to the post page. Alternatively, you can click "View" in
Dashboard -> Posts:
<?php get_header();
require_once('components/navbar.inc.php'); ?>

<?php get_footer(); ?>
You should now see the following website:
This is our HTML markup. Exactly the same as last time, it's static and doesn't fetch any data from our WordPress Blog yet. Let's fix it.
2. The title
If you have a looked at the code you might notice that we have reused some functions like get_header(), require_once('component/navbar.inc.php' or get_footer(). This will take care of our Navbar and Footer. Let's move to the title.
- Update the first lines of the
single.phpfile as follows: - And trailing lines as follows:
- Update our title code:
- using a function, which you already know:
the_title()
<?php get_header();
require_once('components/navbar.inc.php');
if ( have_posts() ) {
while ( have_posts() ) {
the_post();
?>
<!--Main Navigation-->
...
...
<!--Main layout-->
<?php
} // end while
} // end if
get_footer();
?>
That's how we added our WP Loop and dynamically fetch data from database.
<h1 class="font-weight-bold mb-4">Post title</h1>
<h1 class="font-weight-bold mb-4"><?php the_title() ?></h1>
Now you should see the same title as your original post.
Note
You could also use similar function
get_the_title()(notethe_). The difference is thatthe_title()automatically prints the title. In case ofget_the_title(), which returns a string, you have to print it manually i.e. usingecho<?php echo get_the_title(); ?>That doesn't make much sense in that case. However, remember that in the case your title wouldn't show, this approach, can save you a lot of time in debugging :) The second option, is also useful whenever you want to do some text manipulation before printing it. We will learn about that soon.
3. Breadcrumbs
A breadcrumb is a graphical control element frequently used as a navigational aid in user interfaces and on web pages. It allows users to keep track and maintain awareness of their locations within programs, documents, or websites.
- Update the following code: (around line number 50):
- With the following code:
- And refresh the post page.
<!-- Breadcrumbs -->
<ol class="breadcrumb white z-depth-1">
<li class="breadcrumb-item">
<a href="#">Home Page</a>
</li>
<li class="breadcrumb-item">
<a href="#">Marketing Automation Category</a>
</li>
<li class="breadcrumb-item active">Very long title of the post</li>
</ol>
<!-- Breadcrumbs -->
<!-- Breadcrumbs -->
<?php
$categories = get_the_category();
$first_category_name = $categories[0]->cat_name;
$first_category_id = get_cat_ID( $category[0]->cat_name );
$first_category_link = get_category_link( $category_id );
?>
<ol class="breadcrumb white z-depth-1">
<li class="breadcrumb-item">
<a href="<?php echo get_home_url(); ?>">Home Page</a>
</li>
<?php
if (count($categories)){
?>
<li class="breadcrumb-item">
<a href="<?php echo $first_category_link ?>"><?php echo $first_category_name ?></a>
</li>
<?php
}
?>
<li class="breadcrumb-item active"><?php the_title() ?></li>
</ol>
<!-- Breadcrumbs -->
Our breadcrumbs are now automatically generated. They will display a path to our post starting from our HomePage, through Category. Each step is a link either to the main page or a category page (we will create category pages later). That will help users to navigate. As you probably noticed, we are displaying the first category. WordPress allows us to assign more than one category, therefore, we take the first one, or we skip the step if the category is not set.
3. Feature image
- Replace the following code
- With the one below:
<img src="https://mdbootstrap.com/img/Photos/Slides/img%20(144).jpg" class="img-fluid z-depth-1-half mb-4" alt="">
<?php the_post_thumbnail( 'large', array( 'class'=> 'img-fluid z-depth-1-half mb-4')); ?>
4. The post
Now let's take care of our post content part. Exactly same as in previous lessons, we will replace static HTML markup with dynamic WP functions.
- Update the following part:
- By replacing it with the following:
