Allow Contributors To Upload Images In WordPress

Are you running a WordPress website with bunch of contributors who are willing to post on your website? If yes then this article contains a great tip for you.

As I mention on previous articles, every post on your blog must contain at least one image related to the article. It's really great for SEO and other things.

This code will help us to allow users with contributor role to upload images on your WordPress site.

Add this code to your functions.php file:

if ( current_user_can('contributor') && !current_user_can('upload_files') )
     add_action('admin_init', 'allow_contributor_uploads');
    
     function allow_contributor_uploads() {
          $contributor = get_role('contributor');
          $contributor->add_cap('upload_files');
     }

How To Disable Smart/Curly Quotes In WordPress

There are lot of word processor programs which itself converts all yours simple quotes to curly quotes (aka s mart quotes). It looks like small figures six and nine raised above the baseline (like 6...9 and 66...99).

It's a huge problem if you're writing codes in your posts as WordPress automatically converts all quote symbols to smart quotes. So if anyone is copying a snippet from your blog post would have problems with running to code in their own text file.

You can easily disable this feature with a small snippet. Just add following snippet to your functions.php file:

<?php
remove_filter('the_content', 'wptexturize');
remove_filter('comment_text', 'wptexturize');
remove_filter('the_excerpt', 'wptexturize');
?>

That's it!

Send Email Notifications When User Role Changes In WordPress

Yesterday I shared a code which sends an email to the user when the user updates their profile. Today I have something similar, but a bit different. This code sends an email the user when the user's role has changed.

It's a great way to let a member know about the role changes that you'll make. It's also a great trick if you're running a WordPress site with bbPress forum or multiple wirters & contributors.

Just add following to your functions.php:

function user_role_update( $user_id, $new_role ) {
        $site_url = get_bloginfo('wpurl');
        $user_info = get_userdata( $user_id );
        $to = $user_info->user_email;
        $subject = "Role changed: ".$site_url."";
        $message = "Hello " .$user_info->display_name . " your role has changed on ".$site_url.", congratulations you are now an " . $new_role;
        wp_mail($to, $subject, $message);
}
add_action( 'set_user_role', 'user_role_update', 10, 2);

That's it.
