Add download funtionality to Royal PrettyPhoto plugin

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');
/**
 * Adds download functionality to prettyPhoto plugin
 * @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' );
}

WP admin bar – How to hide/replace WordPress icon and blavatars – updated

At the left side of wp admin bar an wordpress icon “W” is shown.

When the user hover it, it lists some wordpress.org links.  Also in multisite installation a wordpress logo (called blavatar) is shown next to each blog name. Also if you have buddypress installed the same blavatar appears in the admin members stats metabox.

A simple way to hide those images or/and replace them with your site favicon is the following.

Just add the functions into your bp-custom.php (or custom.php) file the following:


/**
* Replace wordpress blavatar with site's favicon
*/
function ls_replace_blavatars() {
echo '<style>
#wpadminbar #wp-admin-bar-wp-logo > .ab-item .ab-icon:before {content:" "!important;}
#wpadminbar .quicklinks li .blavatar:before {content:" "!important;}

#wp-admin-bar-wp-logo>.ab-item .ab-icon { background: url("/wp-content/favicon.ico") no-repeat;}
#wpadminbar .quicklinks li div.blavatar { background: url("/wp-content/favicon.ico") no-repeat;}
//for buddypress members stats metabox
div#community-profile-page li.bp-blogs-profile-stats:before {content:" "!important;}
div#community-profile-page li.bp-blogs-profile-stats {background: url("/wp-content/favicon.ico") no-repeat; padding-left:16px}
//end for buddypress stats metabox
}
add_action('admin_head', 'replace_blavatars');

/**
* Remove wordpress logo/pages from admin bar
* @global type $wp_admin_bar
*/
function ls_admin_bar_remove() {
global $wp_admin_bar;
$wp_admin_bar->remove_menu( 'wp-logo' );
}

add_action( 'wp_before_admin_bar_render', 'ls_admin_bar_remove', 0 );


Yet another plugin resurrection :-) BuddyPress Block Activity Stream Types for BP 2.x

Since I manage a very large BP community, I was in a need  of a plugin which reduces the data recorded in the bp_activity table, which stores all the Buddypress activity. A plugin that would  “block” an activity record from being saved to the stream/database. Activities like user joining groups, friendships and profile updates.

But the only plugin which does this was BuddyPress Block Activity Stream Types which was great, but is hasn’t been updated in over 2 years and so isn’t compatible with BP 2.x.

So, based on the ideas and footsteps of this plugin creators I made an updated version for Buddypress 2.x. :-), which uses the Settings API of wordpress and adds a “Buddypress Block Activity Stream Types”  section into Buddypress Settings admin page.

The “resurrected” plugin code is currently available at  https://github.com/lenasterg/buddypress-block-activity-stream-types-ls
