Create shortcode to display posts of custom post type in wordpress

I had to display custom post type posts using short code and for this I have made research and got very nice code in which made some modification.

If anybody need to display custom post type posts using shortcode then you can use this code:

Just paste this code in functions.php


//custom post type function
function verdict_lists() {

register_post_type( 'verdicts',
// CPT Options
array(
'labels' => array(
'name' => __( 'Verdicts' ),
'singular_name' => __( 'Verdict' )
),
'supports' => array( 'title', 'editor', 'excerpt', 'author', 'thumbnail', 'custom-fields' ),
'public' => true,
'has_archive' => true,
'rewrite' => array('slug' => 'verdicts'),
)
);
}
// Hooking up our function to theme setup
add_action( 'init', 'verdict_lists' );

add_shortcode( 'custom_posts', 'verdict_custom_posts' );
function verdict_custom_posts( $atts ){
global $post;
$default = array(
'type' => 'post',
'post_type' => '',
'limit' => -1,
'status' => 'publish'
);
$r = shortcode_atts( $default, $atts );
extract( $r );

if( empty($post_type) )
$post_type = $type;

$post_type_ob = get_post_type_object( $post_type );
if( !$post_type_ob )
return '

No such post type ' . $post_type . ' found.

';

//$return = '

' . $post_type_ob->name . '

';

$args = array(
'post_type' => $post_type,
'numberposts' => $limit,
'post_status' => $status,
);

$posts = get_posts( $args );
if( count($posts) ):
$return .= '

';
foreach( $posts as $post ): setup_postdata( $post );
$return .= '

• '. get_the_title().'

  '. get_the_excerpt().'

  Read more

';

endforeach; wp_reset_postdata();
$return .= '

';
else :
$return .= '

No posts found.

';
endif;

return $return;
}

How to make center bootstrap pop up box or modal

Today, I had need to display bootstrap pop up box in center of screen and after searching got a beautiful solution using javascripts.

Just you need add this JavaScript code and your bootstrap pop up or modal box will be center of the screen.

Like this:

$(function() {
function reposition() {
var modal = $(this),
dialog = modal.find('.modal-dialog');
modal.css('display', 'block');

// Dividing by two centers the modal exactly, but dividing by three
// or four works better for larger screens.
dialog.css("margin-top", Math.max(0, ($(window).height() - dialog.height()) / 2));
}
// Reposition when a modal is shown
$('.modal').on('show.bs.modal', reposition);
// Reposition when the window is resized
$(window).on('resize', function() {
$('.modal:visible').each(reposition);
});
});

Hope, it will help for some people.
