I am looking for a way to remove all the unessesary text from default worpdress metaboxes.
Preferably I would like to ensure that the content is not just hidden through CSS but actually removed from the HTML so it does not even show up in the source.

Here's an answer to question #1. Not enough time right now to do the rest.
Unfortunately WordPress doesn't provide a hook to let you affect the Help Button on the top right of the admin, but you can use a somewhat dirty hack to achieve what you are trying to accomplish.
(source: mikeschinkel)
(source: mikeschinkel)
By calling the contextual_help and admin_notices hooks, the ones that are called immediately before and immediately after when the help link button is output, respectively, you can capture the output buffer and remove the offending HTML using preg_replace(). The ob_start()/ob_get_clean() pair of functions in PHP are what you need to buffer output and then to capture that buffered output, viola:
class RemoveAdminHelpLinkButton {
static function on_load() {
add_filter('contextual_help',array(__CLASS__,'contextual_help'));
add_action('admin_notices',array(__CLASS__,'admin_notices'));
}
static function contextual_help($contextual_help) {
ob_start();
return $contextual_help;
}
static function admin_notices() {
echo preg_replace('#<div id="contextual-help-link-wrap".*>.*</div>#Us','',ob_get_clean());
}
}
RemoveAdminHelpLinkButton::on_load();
In general you can use this technique to modify or delete almost any HTML output generated by WordPress by finding the before and after hooks but be aware that it is a very fragile technique; if another plugin has modified the HTML output from what you were expecting your preg_replace() could fail to match. Anyway...
To remove the help text for the Page Attributes metabox doesn't require regular expressions, a simple str_replace() will do. (Note finding the right hooks to use took the most time.):
class RemovePageAttributesHelpText {
static function on_load() {
add_action('admin_notices',array(__CLASS__,'admin_notices'));
add_action('dbx_post_sidebar',array(__CLASS__,'dbx_post_sidebar'));
}
static function admin_notices() {
ob_start();
}
static function dbx_post_sidebar() {
$match_text = '<p>Need help? Use the Help tab in the upper right of your screen.</p>';
echo str_replace($match_text,'',ob_get_clean());
}
}
RemovePageAttributesHelpText::on_load();
There's also another approach you can use when all you want to do it remove text from core and that's to use the 'gettext' hook. The following code removes the help text from the Page Attributes metabox:
class RemovePageAttributesHelpText {
static function on_load() {
add_filter('gettext',array(__CLASS__,'gettext'),10,4);
}
function gettext($translation, $text, $domain) {
if ($text=='Need help? Use the Help tab in the upper right of your screen.') {
$translation = '';
}
return $translation;
}
}
RemovePageAttributesHelpText::on_load();
Note that I'm cautious to use this hook as it gets called hundreds of times per page load; 577 times just to load the Admin Dashboard in case I just tested, for example. So if you use it be sure not to do anything that is computationally "expensive" such as running a raw SQL query or similar.
We'll use option #2 from technique #3 to strip the help text from the Excerpt Metabox (this one I included the code from technique #3 so this one replaces the code in #3):
class RemoveUnwantedPageEditingText {
static function on_load() {
add_action('admin_notices',array(__CLASS__,'admin_notices'));
add_action('dbx_post_sidebar',array(__CLASS__,'dbx_post_sidebar'));
}
static function admin_notices() {
ob_start();
}
static function dbx_post_sidebar() {
$html = str_replace('<p>Need help? Use the Help tab in the upper right of your screen.</p>','',ob_get_clean());
echo str_replace('Excerpts are optional hand-crafted summaries of your content that can be used in your theme.' .
' <a href="http://codex.wordpress/Excerpt" target="_blank">Learn more about manual excerpts.</a>','',$html);
}
}
RemoveUnwantedPageEditingText::on_load();
Jake Goldman's excellent talk at WordCamp Mid-Atlantic provides an excellent guide: http://www.cmurrayconsulting/wordpress-tips/customizing-wordpress-admin/#more-939
Download the well-commented theme that appears below the slideshow. (He asks that if you use his code, you please attribute it to him in your code comments.)
He mentions that you can get all the widget IDs as follows: var_dump( $wp_meta_boxes['dashboard'] );
You could: unset($wp_meta_boxes['dashboard']['normal']['core']['dashboard_right_now']);
Then add your own widget using wp_add_dashboard_widget().
Look in wp-admin/includes/dashboard.php for the function, wp_dashboard_right_now() for a model for what to add (deleting theme info, as desired.)

Alternativ and very easy: use the plugin Adminimize, this plugin have many options and you can add your own options. This plugin is my own and i will coding a newer plugin with better code. Maybe its help for a csutom solution to read the source.
