#index.php

The reason why we need to remove index.php is to get the website crawl by google or any other search engines. Google will not crawl your url if your url contains index.php.

Magento doesn’t handle SSL certificates on load balanced servers very well.

Fix it with this. 

.htaccess

... SetEnvIf X-Forwarded-Proto "^https$" HTTPS=on

And stick this in index.php, before the Mage::run line

foreach (array(    'SERVER_PORT' => 443,    'HTTP_X_FORWARDED_PROTO' => 'https',    'HTTP_CF_VISITOR' => '{"scheme":"https"}' ) as $key => $value) {    if (isset($_SERVER[$key]) && $_SERVER[$key] == $value) {        $_SERVER['HTTPS'] = 'on';        $_SERVER['SERVER_PORT'] = 443;        break;    } }

WordPress: Display a List of Last Updated Posts

If you are using last modified date, then you might want to show a list of your recently updated posts on your site. Each time you update a post, WordPress stores the date and time of that update in the posts table as last updated date. We will show you how to create a custom WordPress query to list your most recently updated articles.

Copy code below to your functions.php

function wpb_lastupdated_posts() // Query Arguments $lastupdated_args = array( 'orderby' => 'modified', 'ignore_sticky_posts' => '1' ); //Loop to display 5 recently updated posts $lastupdated_loop = new WP_Query( $lastupdated_args ); $counter = 1; echo '<ul>'; while( $lastupdated_loop->have_posts() && $counter < 5 ) : $lastupdated_loop->the_post(); echo '<li><a href="' . get_permalink( $lastupdated_loop->post->ID ) . '"> ' .get_the_title( $lastupdated_loop->post->ID ) . '</a> ( '. get_the_modified_date() .') </li>'; $counter++; endwhile; echo '</ul>'; wp_reset_postdata(); //add a shortcode add_shortcode('lastupdated-posts', 'wpb_lastupdated_posts');

That’s all. Now if you want to display last updated posts in your theme’s template files, then you can use it like this:

<?php if (function_exists(wpb_lastupdated_posts)) : wpb_lastupdated_posts(); endif; ?>

And if you need to change in the posts or pages then you need to open these files: index.php or home.php, single.php and page.php. But sometimes theme developer change this file with template, like loop.php inside include folder.

Then you will need to locate the following code:

<?php the_modified_time('F jS, Y');?>

Replace it with:

<?php $u_time = get_the_time('U'); $u_modified_time = get_the_modified_time('U'); if ($u_modified_time >= $u_time + 86400) echo "and last modified on "; the_modified_time('F jS, Y'); echo " at "; the_modified_time(); echo ", "; ?>

Or maybe you want to not change the original post date instead add last updated info below post date, you could try WordPress plugin Last Updated Shortcode.

Cuando empezamos a crear nuestro propio tema de Wordpress, hay que considerar que hay archivos más importantes que otros. Lo más importantes son index.php y style.css.

Del archivo index.php se desprenden los siguientes archivos:

single.php

archive.php

category.php

functions.php

page.php

404.php

home.php

etc.

Del Index se desprenden los archivos:

Header.php

loop.php

sidebar.php

footer.php

Estos se llaman en index.php por medio de funciones:

get_header(); get_sidebar(); get_footer(); get_template_part('loop');
