I have been asked several times by clients or collaborators to simplify  the admin interface of WordPress. Which is a problem, as I do not want my modifications to magically disappear at each WordPress update. So, one solution could be to simply hide the unused elements via CSS. Here is how it works:

First, add a stylesheet, simple-wp-admin.css to ypur theme which basically puts a « display: none » on the elements in the the post and page editor you want to hide. These elements are post revisions, comments etc. It contains something like this :

#post-body normal-sortables, #post-body #advanced-sortables {
display: none;
}

Then add  the following code to functions.php (in the theme folder), which calls the custom stylesheet from the admin interface.

<?php function simplify_admin_interface() {
$url = get_bloginfo('stylesheet_directory') . '/simple-wp-admin.css';
echo '<link rel="stylesheet" type="text/css" href="' . $url . '" />';
}

add_action('admin_head', 'simplify_admin_interface');
?>

That’s all.

(One could probably add an option to distinguish the user’s role and capabilities, so the advanced options will be hidden only for non administrators. I implemented this in the plugin I finally wrote, wp_simple_admin.)

Chez 1and1.fr WordPress fonctionne à merveille – il suffit de dire qu’on veut utiliser PHP5, et non PHP4, qui est la version de PHP utilisée par défaut sur leurs serveurs. Sans cela, la mise à jour automatique, l’installation via l’interface d’administration d’extensions et de thèmes et l’upload de fichiers ne fonctionnent pas correctement.

Il suffit, à la racine de l’installation WordPress, d’ajouter un fichier .htaccess (ou d’ajouter au fichier .htaccess présent) les lignes suivantes :

AddType x-mapp-php5 .php
AddHandler x-mapp-php5 .php

For a client I was looking for a slideshow which could be easily integrated with WordPress and galleria-wp has been my choice.
It just does not start the slideshow automatically…

In order to do this I added the following lines of code to the showNavigation if-loop :

if ( $showNavigation == 1 ) {
  // code..
} else {
  // autoplay
  jQuery(window).load( function() {
  timerID_$galleryID = setInterval( \"jQuery.galleria.next( 'stage_$galleryID', '$galleryID' );\", $intervalMilliSec );
 });
}

Now, if one unselects « show navigation » in wp-galleria’s admin panel in WordPress, the slideshow will autoplay.
