save post

hey guys !

Am not really sure that i could post that question over here… so, forgive me if am wrong ??
Moreover, i tried to search on the forum any solutions… without success or am blind ??

Well, am looking for a hook that let me retrieve all the $_POST values when a post is edited/added… Here’s my code :

add_action('admin_menu', 'post_options_box');
add_action('save_post ', 'str_save_post');

function post_options_box()
{
	add_meta_box('MetaBox', 'STRApp-It', 'str_draw_panel', 'post', 'side', 'high');
	add_meta_box('MetaBox', 'STRApp-It', 'str_draw_panel', 'page', 'side', 'high');
}

function str_draw_panel()
{
	$target_content_values = array('key1' 				=> 'val1',
								   'key2'		=> 'val2',
								   'key3'				=> 'val3);
	global $post;
	$meta_values = get_post_meta($post->ID, '_target_content', false);
	//var_dump($meta_values);
	$action = 'add';
	if (sizeof($meta_values) > 0) {
		$action = 'update';
	}

	?>
		<h4>Target</h4>
		<input type="hidden" name="_target_content_action" value="<?php echo $action ?>" />
		<?php
			foreach ($target_content_values as $key => $value) {
				$checked = '';
				if($key == $meta_values[0])
					$checked = 'checked';
				?>
					<input type="radio" name="_target_content" value="<?php echo $key ?>" <?php echo $checked ?> /><?php echo $value ?><br />
				<?php
			}
		?>
	<?php
}

function str_save_post($post_id, $post)
{
	var_dump($_POST);
	die();
}

unfortunately, i see that when i click on the update button in the admin panel, nobody comes in my str_save_post function… Does anybody know what am doing wrong ??

As you can see, am starting plugin developments on WordPress and am a lil bit lost ! ??

Thanks for your help guys !
