Now that we have now the type.css file arrange let’s transfer on to creating the opposite important theme recordsdata.

Step 3: Create the primary template file in your theme

The index.php file serves as the primary template file in your theme. Any code you add right here is used to show the primary content material of your website.

For instance, in case you add some fundamental HTML code right here, all the things shows if you activate and preview the theme. Nevertheless, you need to pull info out of your WordPress CMS to show by way of your theme’s template file, and that is the place you employ PHP to add WordPress features.

Here's what the essential construction of the index.php file can seem like:

Within the above construction, get_header() and get_footer() are used to pull the header and footer sections from their respective template recordsdata (header.php and footer.php).

We are going to populate the index.php file with the appropriate code, however let’s first work on the theme’s header and footer sections.

Step 4: Create the header file

The header.php file shows your website’s header part, which generally contains parts like the location brand and navigation menu. It additionally contains stylesheets, scripts, and meta tags. Here's what our header.php file seems to be like:

Let’s break down and clarify every a part of this file and add the corresponding features and hooks to features.php.

Let’s start with the part. This part contains important metadata, the location title, character encoding, and the wp_head() perform:


>

    
    
    
The language_attributes(); perform units the language attributes for the HTML doc. Then, the wp_head(); perform is essential because it permits WordPress and plugins to insert important parts into the  part, corresponding to stylesheets and scripts.
Data
At all times wrap WordPress features in  tags.
Enqueue the stylesheet by including the next to features.php:
perform my_custom_theme_enqueue_styles() {
    // Enqueue the primary stylesheet
    wp_enqueue_style('my-custom-theme-style', get_stylesheet_uri());
}

add_action('wp_enqueue_scripts', 'my_custom_theme_enqueue_styles');
The perform wp_enqueue_style() provides the primary stylesheet to the pinnacle part. We prefix the perform with my_custom_theme to keep away from conflicts with different themes or plugins. You could resolve to add this immediately to the pinnacle tag with the  tag.
Equally, let’s declare a perform to add the location title to the pinnacle part:
perform my_custom_theme_wp_title() {
    add_theme_support('title-tag');
}

add_action('after_setup_theme', 'my_custom_theme_wp_title');
Now, due to the wp_head() perform, the type and title tag are added to the header dynamically. You possibly can confirm this by inspecting your WordPress website together with your browser’s developer instruments. Within the  part, it is best to see the stylesheet hyperlink and the dynamically generated title tag, confirming that they're included.
Subsequent, within the physique, we declared the navbar part the place we present a dummy brand and guarantee an choice for utilizing a {custom} brand when set within the WordPress website id:

    
The emblem part makes use of the the_custom_logo() perform to show a {custom} brand if one is ready. If no {custom} brand is ready, it shows a default picture.
To allow {custom} brand help, add the next code to features.php:
perform my_custom_theme_setup() {
    add_theme_support('custom-logo', array(
        'peak'      => 100,
        'width'       => 400,
        'flex-height' => true,
        'flex-width'  => true,
    ));
}

add_action('after_setup_theme', 'my_custom_theme_setup');
This perform provides help for a {custom} brand. Lastly, the navigation menu part:
        
             'header-menu',
                'menu_class' => 'header-menu'
            )); ?>
        
    
The wp_nav_menu() perform shows the navigation menu assigned to the “Header Menu” location. To register the navigation menu, guarantee you have got this code in features.php:
register_nav_menus(array(
    'header-menu' => __('Header Menu', 'my-custom-theme'),
));
Here's what your perform.php file will seem like now:
 100,
        'width'       => 400,
        'flex-height' => true,
        'flex-width'  => true,
    ));
}
add_action('after_setup_theme', 'my_custom_theme_setup');

perform my_custom_theme_enqueue_styles() {
    // Enqueue the primary stylesheet
    wp_enqueue_style('my-custom-theme-style', get_stylesheet_uri());
}
add_action('wp_enqueue_scripts', 'my_custom_theme_enqueue_styles');

// Perform to add the location title to the pinnacle part
perform my_custom_theme_wp_title() {
    add_theme_support('title-tag');
}
add_action('after_setup_theme', 'my_custom_theme_wp_title');
?>
By following these steps, you make sure that your header helps a {custom} brand and shows a navigation menu, making it dynamic and simply customizable by way of the WordPress admin dashboard.
Step 5: Create the footer file
The footer.php file will probably be accountable for displaying the footer part of your website. For this theme, the footer.php file will solely show the copyright 12 months:

  Copyright © 2024



On this file, we embody the wp_footer() perform, related to how we included wp_head() within the header. The wp_footer() perform permits WordPress and plugins to insert important parts, corresponding to scripts, simply earlier than the closing  tag. That is essential for guaranteeing that each one essential sources are loaded appropriately and your website features as anticipated.
Step 6: Displaying weblog posts with the WordPress loop
Let’s return to the index.php file to clarify how to loop by way of and show posts out of your WordPress website utilizing the WordPress loop — a highly effective approach to show content material dynamically. That is what the loop seems to be like:

    
        
            
                
                    
                
                
                
                
            
        
    
        
            Sorry, no posts have been discovered!
        
    
The code above checks for any posts to show earlier than coming into the loop. Within the loop, WordPress features like the_title(), the_author(), the_time('F j, Y'), and the_excerpt() show details about every WordPress submit.
The the_post_thumbnail() perform can also be used to show the thumbnail, however that is wrapped in an if assertion, so it solely shows when there may be a featured picture in your submit. Within the features.php file, we should add help for submit thumbnails with this perform so there may be an choice to add featured photographs if you create new posts:
add_theme_support('post-thumbnails');
Add this to the my_custom_theme_setup() perform we created within the features.php file. That is what the index.php file now seems to be like:


    
        
        Right here, you will discover posts on a number of subjects, together with programming, net improvement, and extra.
    

    
        
            
                
                    
                        
                    
                    
                    
                    
                
            
        
            
                Sorry, no posts have been discovered!
            
        
    

You'll discover some static code is added, which will probably be styled as a banner displaying “Welcome to my blog” and a paragraph of textual content.
Step 7: Creating a single submit template

Within the code above, get_header() and get_footer() embody the header and footer. In different components of the code, WordPress features show dynamic content material.
