have_post() does return null value in wp

Question

I used the following code in my page template:

<?php
while(have_posts()):the_post();
the_content();
?>

But nothing is displayed. The loop is not working. I'm sure that, there is sufficient information as content in my template page.

Answer 1

You should use if condition to check if post exists else skip the loop. Make sure to ON the error log and check the exact error.

<?php wp_reset_query(); ?>
<?php if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>
<?php the_content(); ?>
<?php endwhile; else: ?>
<p><?php _e('Sorry, no posts matched your criteria.'); ?></p>
<?php endif; ?>

Answer 2

<?php
/**
* Template Name: My Template
*/

the_post();
the_content();
?>

If you save the following code as a page template and call the page template into a page by choosing it, then the page will show the page content without any hassle.

Note: it's THE minimal bit of code.

Answer 3

use the following code Try using wp_reset_query()

 <?php
    wp_reset_query();
    while(have_posts()):the_post();
    the_content();
    endwhile;
   ?>
