Explanation

To add custom page layouts in WordPress, you can create a special template file that allows you to design pages differently from the default layout. Here's a simple way to do it:

Register the Custom Template: Use a function to add your custom template to the list of available page templates. This makes it selectable when editing a page in WordPress.


function wp_dudecom_add_custom_page_templates($post_templates) {
    $post_templates['templates/custom-template.php'] = __('Custom Template', 'textdomain');
    return $post_templates;
}
add_filter('theme_page_templates', 'wp_dudecom_add_custom_page_templates');

Load the Custom Template: Ensure WordPress uses your custom template file when the page is viewed. This function checks if the page is using your template and loads it accordingly.


function wp_dudecom_load_custom_page_template($template) {
    global $post;

    if ($post && 'templates/custom-template.php' === get_post_meta($post->ID, '_wp_page_template', true)) {
        $template = get_template_directory() . '/templates/custom-template.php';
    }

    return $template;
}
add_filter('template_include', 'wp_dudecom_load_custom_page_template');

Create the Template File: Automatically create the template file if it doesn't exist. This file contains the HTML structure and WordPress functions to display the page content.


function wp_dudecom_check_custom_template_file() {
    $custom_template_path = get_template_directory() . '/templates/custom-template.php';

    if (!file_exists($custom_template_path)) {
        $custom_template_content = "\n\n\n    
\n    
\n\n\n";
        wp_mkdir_p(get_template_directory() . '/templates');
        file_put_contents($custom_template_path, $custom_template_content);
    }
}
add_action('after_setup_theme', 'wp_dudecom_check_custom_template_file');

Add Custom Styling: Add a unique class to the body tag when your custom template is used. This helps you apply specific styles using CSS.


function wp_dudecom_custom_body_class($classes) {
    if (is_page_template('templates/custom-template.php')) {
        $classes[] = 'custom-template';
    }
    return $classes;
}
add_filter('body_class', 'wp_dudecom_custom_body_class');

With these steps, you can create and use custom page layouts in WordPress, giving you more control over the design and functionality of your pages.

Code

<?php
// Add custom page templates to WordPress theme

// Hook into 'theme_page_templates' to add custom templates
function wp_dudecom_add_custom_page_templates($post_templates) {
    $post_templates['templates/custom-template.php'] = __('Custom Template', 'textdomain');
    return $post_templates;
}
add_filter('theme_page_templates', 'wp_dudecom_add_custom_page_templates');

// Load custom template file
function wp_dudecom_load_custom_page_template($template) {
    global $post;

    if ($post && 'templates/custom-template.php' === get_post_meta($post->ID, '_wp_page_template', true)) {
        $template = get_template_directory() . '/templates/custom-template.php';
    }

    return $template;
}
add_filter('template_include', 'wp_dudecom_load_custom_page_template');

// Ensure custom template file exists
function wp_dudecom_check_custom_template_file() {
    $custom_template_path = get_template_directory() . '/templates/custom-template.php';

    if (!file_exists($custom_template_path)) {
        $custom_template_content = "<?php\n/*\nTemplate Name: Custom Template\n*/\n\nget_header();\n?>\n\n<div class=\"custom-template-content\">\n    <h1><?php the_title(); ?></h1>\n    <div><?php the_content(); ?></div>\n</div>\n\n<?php get_footer(); ?>";
        wp_mkdir_p(get_template_directory() . '/templates');
        file_put_contents($custom_template_path, $custom_template_content);
    }
}
add_action('after_setup_theme', 'wp_dudecom_check_custom_template_file');

// Add custom body class for styling
function wp_dudecom_custom_body_class($classes) {
    if (is_page_template('templates/custom-template.php')) {
        $classes[] = 'custom-template';
    }
    return $classes;
}
add_filter('body_class', 'wp_dudecom_custom_body_class');
?>

Instructions

To implement custom page layouts in WordPress, follow these steps:

File Location: Add the provided code to your theme's functions.php file.

Prerequisites: Ensure you have access to your WordPress theme files and a basic understanding of how to edit them.

Open your theme's functions.php file: Navigate to Appearance > Theme Editor in your WordPress dashboard, and select functions.php from the list of theme files.
Copy and paste the code: Insert the provided code snippet into your functions.php file. This code will register a custom page template, load it when selected, create the template file if it doesn't exist, and add a custom body class for styling.
Save the changes: After pasting the code, save the changes to your functions.php file.
Create the template directory: Ensure that the templates directory exists within your theme folder. The code will automatically create the custom-template.php file if it doesn't exist.
Select the custom template for a page: Go to Pages > Add New or edit an existing page. In the Page Attributes section, select Custom Template from the Template dropdown menu.
Customize the template: Edit the custom-template.php file located in the templates directory of your theme to customize the layout and design as needed.

By following these steps, you can effectively add and use custom page layouts in WordPress. For further assistance or advanced functionality, consider reaching out to wp-dude.com for professional help.
