if custom post type exist

I want to test if custom post type mobile exist. I used if custom post type exist in the loop, but it doesn’t work. Any suggestion why my code is not working

<?php /* The loop */ ?>
<?php if ( have_posts() ) : ?>...

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

<? if( post_type_exists( 'mobiles' ) ) {  echo 'The Products post type   exists';} ?>
<?php get_template_part( 'content', get_post_format() ); ?>

<?pp echo 'The post type is: '. get_post_type( get_the_ID() ); ?>

<?php endwhile; ?>
<?php twentythirteen_paging_nav(); ?>
<?php else : ?>
<?php get_template_part( 'content', 'none' ); ?>
<?php endif; ?>

You typed “mobiles” when you said you wanted to check for post type “mobile”. So simply remove the s ;).

<? if( post_type_exists( 'mobiles' ) ) {  echo 'The Products post type   exists';} ?> 

Should be:

<? if( post_type_exists( 'mobile' ) ) {  echo 'The Mobile post type   exists';} ?>

If it’s still not working, triple check if you succesfully registered a post type named “mobile”.
