Clone an entire page to custom index.php

Question

I am building a custom index.php file in my child theme overriding the default theme index.php file which loads first when the theme is first installed.

Is there a way to clone an entire page to index.php file by page name or id or slug? I will build a page by adding a new page from dashboard and add elements there. Now, when I build the page, I also want the index.php file look the same. Hope I make sense.

I have created a custom template as the index.php file. But not sure about the cloning process. Any help will be appreciative.

thanks

Answer 1

You can get the code from page.php of your parent theme inside your index.php - in this file you'll have all that is needed to display a page. For example in WP default theme, this code from page.php will display the current page using content-page.php template :

while ( have_posts() ) : the_post();
    get_template_part( 'content', 'page' );
    endif;
endwhile;

Then, in WP settings, define your page as home page in Settings > Reading - it will tell wordpress to use that page for your index.php template.

I got it resolved this way.

<?php
            if ( have_posts() ) :
                while ( have_posts() ) : the_post();
                    $post_format = et_pb_post_format(); ?>
<?php
                    $page = get_page_by_title('Default Homepage'); 
$content = apply_filters('the_content', $page->post_content);
echo $content;
?>
