How To Add Custom User Roles In WordPress ?

Leave a comment

Suppose you need to create a new custom post type, may be NEWS. So that you can allow you subscribers to post NEWS on your website. In the given example we will be creating a custom user role for NEWS and the users allotted this role would only be managing only NEWS section from WP-Admin (Dashboard).

Open your theme’s function.php file: site root >> wp-content >>themes >> function.php and add the given code block:

add_role( ‘news_user’, ‘News User’, array( ‘news’ ) );

This function generates new custom user role which can only manage
news section from Dashboard.

Although you may add some more function for new custom user role.

New custom user role can also be removed from WordPress by using the following function in your theme’s function.php file:

remove_role( ‘news_user’ );

From WordPress Function $wp_roles also you can add and remove custom user roles as show below:

global $wp_roles;
$wp_roles->add_cap( ‘news_user’, ‘manage_category’ );
$wp_roles->remove_cap( ‘news_user’, ‘view_post’ );

‘public’ => true,
‘exclude_from_search’ => false,
‘show_in_admin_all_list’ => true,
‘show_in_admin_status_list’ => true,
‘label_count’ => _n_noop( ‘Unread <span class=”count”>(%s)</span>’, ‘Unread <span class=”count”>(%s)</span>’ ),
) );
}
add_action( ‘init’, ‘my_custom_post_status’ );

Add ‘Pin It’ Button To Images In Your WordPress Blog

Leave a comment

Without using Plugin: Add this code to your theme’s footer.php file before the </body> tag. Get Pinterest’s javascript at Goodies.

<script type=”text/javascript” src=”//assets.pinterest.com/js/pinit.js”></script>

Add this code to your theme’s single.php file wherever you want Pin It button to be visible:

<a href=”http://pinterest.com/pin/create/button/?url=<?php the_permalink(); ?>&media=<?php echo catch_that_image() ?>&description=<?php the_title(); ?>” class=”pin-it-button” count-layout=”horizontal”><img border=”0″ src=”//assets.pinterest.com/images/PinExt.png” title=”Pin It” /></a>

Add this code in your theme’s functions.php file:

function catch_that_image() {
global $post, $posts;
$first_img = ”;
ob_start();
ob_end_clean();
$output = preg_match_all(‘/<img.+src=[‘”]([^'”]+)[‘”].*>/i’, $post->post_content, $matches);
$first_img = $matches [1] [0];
if(empty($first_img)){ //Defines a default image
$first_img = “/images/default.jpg”;
}
return $first_img;
}

Or You may use a WordPress plugin and that would be more easy for you. Use this plugin Pinterest Pin It Button For Images. Either search it on WP Plugin search or click the link and upload the folder to the /wp-content/plugins/ directory, Activate from ‘Plugins’ menu and Enjoy.
