Add a sortable user Id column into WordPress Users table


Sometimes it is useful to find the user_id of each user you have in your WordPress site.  This is especially helpful if you have a multisite with a lots of users.  Something like this:

user_d

In order to have that kind of functionality,  you can add the following code in your theme’s functions.php.
If you have a multisite installation the ID column will be only displayed in the network users admin page and not in each subsite’s users admin table.

Override bp-signups view with pending users view from ‘new user approve’ plugin


Using BuddyPress and New user approve plugin is a bit confusing for the admin, cause the “pending” users link on top of  users table in admin page, points to BuddyPress pending users. But when the ‘New user approve’ plugin is activated, the pending users are shown in a different page.

In order to fix the link “Pending” displayed on top of the users table, the following filter is needed.

A way to extend Royal prettyPhoto plugin to support download image functionality is via Javascript.

Just put the following lines into the functions.php of your theme file.

add_action('wp_footer','ls_prettyPhoto_Download');
/**

 * @author lenasterg
 */
function ls_prettyPhoto_Download() {
 echo '<style>.pp_download{ background: #ccc; border-radius: 3px; height: 25px; padding: 4px;}</style>


jQuery(document).ready(function() {
 jQuery("a[rel^=\'prettyPhoto\']").prettyPhoto({
 changepicturecallback: function(){
 jQuery(".pp_social").append("");
 $getit= settings.image_markup.replace(/{path}/g,pp_images[set_position]);
 jQuery(".pp_pic_holder").find(\'.pp_details .pp_download_place\').html(\'Download\');
 }
 });
});
';
}

Email to superadmin when a subsite has low available space


Since part of my job is to support a very, very large multisite (and multiuser) WordPress installation, I deal daily with user’s requests and problems.

One of the most frustrating things for them and me, is when the available space of their blog is low. They have to report it to our helpdesk and then wait till we increase it.

Since I couldn’t find a plugin which notice the network admin about low space in subblogs,  I wrote a simple function which does it.

The function sends an email to the network admin when the available space is less then 200MB. It runs every time the blog admin visits the control panel of his/her’s blog.
Just add the following code in your custom.php file.

/**
* Send email to super admin when the blog's available space is less than 200MB
*/
function ls_blog_space_mail() {
$space_left = round( get_upload_space_available() / 1024 / 1024 );
if ( $space_left < 200 ) {
$message = 'Site ' . get_site_url() . ' has only ' . $space_left . 'MB space left. '
. 'If you wish to expand the available space visit ' . network_admin_url( 'site-settings.php?id=' . get_current_blog_id() ) . ' and increase the "' . __( 'Site Upload Space Quota' ) . '."';
wp_mail( get_site_option( 'admin_email' ), "[ " . wp_specialchars_decode( get_option( 'blogname' ) ) . " ]. Low available space", $message );
}
}


if ( is_multisite() ) {
add_action( 'activity_box_end', 'ls_blog_space_mail' );
}
