I just add this code to drupal documentation page in http://drupal.org/node/478328

paste this in your template.php file in theme directory.

<?php
/**
* This snippet will register a theme implementation of the user login form.
*
* Drupal 6.x only!
* Replace 'mytheme' with the name of your theme.
*/
function MYTHEME_theme(){
  return array(
    'user_login_block' => array(
      'template' => 'user-login-block',
      'arguments' => array('form' => NULL),
    )
  );
}
 
function MYTHEME_preprocess_user_login_block(&$variables) {
     // Add a custom placeholder to username field.
    $variables['form']['name']['#value'] = $variables['form']['name']['#title'];
    $variables['form']['name']['#attributes']['onblur'] = "if (this.value == '') {this.value = '".$variables['form']['name']['#value']."';} ;";
    $variables['form']['name']['#attributes']['onfocus'] = "if (this.value == '".$variables['form']['name']['#value']."') {this.value = '';} ;";
 
    // Add a custom placeholder to password field.
    // this will not work until you clicked in input, to make this work see <a href="http://drupal.org/node/75225" title="http://drupal.org/node/75225">http://drupal.org/node/75225</a> and apply the patch
    $variables['form']['pass']['#value'] = $variables['form']['pass']['#title'];
    $variables['form']['pass']['#attributes']['onblur'] = "if (this.value == '') {this.value = '".$variables['form']['pass']['#value']."';} ;";
    $variables['form']['pass']['#attributes']['onfocus'] = "if (this.value == '".$variables['form']['pass']['#value']."') {this.value = '';} ;";
 
    // Remove the "Username" & "Password" labels from the form.
    unset($variables['form']['name']['#title']);
    unset($variables['form']['pass']['#title']);
 
    // Add some classes
    $variables['form']['name']['#attributes']['class'] = 'name-field-login-form';
    $variables['form']['pass']['#attributes']['class'] = 'pass-field-login-form';
    $variables['form']['submit']['#attributes']['class'] = 'submit-field-login-form';
 
    // Change the text on the submit button
    //$variables['form']['submit']['#value'] = t('Login');
 
    // Make the submit button (image)
    $variables['form']['submit']['#type'] = 'image_button';
    $variables['form']['submit']['#src'] = path_to_theme() . '/images/login.png';
 
   // Remove links
   //unset($variables['form']['links']);
    $variables['form']['name']['#required'] = false;
    $variables['form']['pass']['#required'] = false;
    $variables['rendered'] = drupal_render($variables['form']);
}
?>

Note that password input will not work (will not get a default value),
See http://drupal.org/node/75225 and apply the patch

Make a new file "user-login-block.tpl.php" in your theme, and add the following:

<div class="login-form-custom">
  <?php print $rendered; ?>
</div>

Now clear your theme registry by visiting and saving /admin/build/themes, and your new tpl.php should work.

paste this in your template.php file in theme directory, please read following code and customize with your needs

<?php
function MYTHEME_preprocess_search_theme_form(&$variables, $hook) {
	// Add a custom placeholder text to Search box field.
	$variables['form']['search_theme_form']['#value'] = $variables['form']['search_theme_form']['#title'];
	$variables['form']['search_theme_form']['#attributes']['onblur'] = "if (this.value == '') {this.value = '".$variables['form']['search_theme_form']['#value']."';} ;";
	$variables['form']['search_theme_form']['#attributes']['onfocus'] = "if (this.value == '".$variables['form']['search_theme_form']['#value']."') {this.value = '';} ;";
 
	// Remove the "Search this site" label from the form.
	unset($variables['form']['search_theme_form']['#title']);
 
	// Add a custom class to the search box.
	$variables['form']['search_theme_form']['#attributes']['class'] = 'search-box';
 
	//change the text field size
	$variables['form']['search_theme_form']['#size'] = 25;
 
	// Change the text on the submit button
	//$variables['form']['submit']['#value'] = t('Go');
 
	// Rebuild the rendered version (search form only, rest remains unchanged)
	unset($variables['form']['search_theme_form']['#printed']);
	$variables['search']['search_theme_form'] = drupal_render($variables['form']['search_theme_form']);
 
	$variables['form']['submit']['#type'] = 'image_button';
	$variables['form']['submit']['#src'] = path_to_theme().'/images/search.png';
 
	// Rebuild the rendered version (submit button, rest remains unchanged)
	unset($variables['form']['submit']['#printed']);
	$variables['search']['submit'] = drupal_render($variables['form']['submit']);
 
	// Collect all form elements to make it easier to print the whole form.
	$variables['search_form'] = implode($variables['search']);
}
}

why to use Drupal?
as a user, developer, themer ,sysadmin ..etc

This function multiply any two arrays (Matrix) with matrix multiply conditions ,get entry from files

attach:
file:array1.txt
content:
3;5;4
6;2;3

file:array2.txt
content:
2;1
6;7
8;9

Code:

<?php
/*
 * Created By Ayham Alsuleman in 25\10\2010 9:22am

*/
 
//check if the gives file is a matrix
function IsMatrix($file){
	if (file_exists($file)){
		//read the file
		$array = file($file);
		$rows = count($array);

		foreach ($array as $k =>$line){
			$linecols = count(split(';',$line));
			if($linecols !== $cols){

		//to multiply two arrays the close dimensions must be equal 
		//and the result array will be dimensions of the sides ..
		//e.g array1[5,2]*array2[2,3] we can multiply because the close dimensions equals 2 = 2

you need :
Token + Token actions + Trigger
1- Go to admin/settings/actions/manage
2- add Redirect to a tokenized URL... and enter
user/[UID]/edit then save
3- Go to admin/build/trigger/user
4- after register select from dropdown list Redirect to a tokenized URL then click Assign

you can customize this page with
profile category weight
one page profile

This code allow block to show in
training
training/*
content type 'product'
and all terms with taxonomy id 3,6,7

<?php
if ( ($_GET['q'] == 'training') or (substr($_GET['q'],0,9 ) == 'training/')){
 return true;
}else{
	// valid node id in view mode
	if ( arg(0) == 'node' AND is_numeric(arg(1)) AND arg(2) == FALSE ) {
	    $node = node_load(arg(1)); // cached
	    if ( ($node->type == 'product') ) {
	        return true;
	    }
	}else{
$match = FALSE;
 
 
	// put here the vocabulary ID you're interested in
	$vids = array(3,6,7);
 
  if (arg(0) == 'taxonomy' && arg(1) == 'term') {
	  foreach( $vids as $vk => $vid){
		  $str_tids = arg(2); 
		  $terms = taxonomy_get_tree($vid);
		  foreach ( $terms as $term ) {
		    $items[] = $term->tid;
		  }
 
		  $terms = taxonomy_terms_parse_string($str_tids); 
 
		  //browse each value
		  foreach ($terms['tids'] as $k => $v) {
		    if (in_array($v, $items)) {
		      $match = TRUE;
		    }
		  }
	 	}
	}
}
return $match;
 
}
return FALSE;
?>

make custom Breadcrumb in taxonomy term page

<?php
function YOURTHEME_breadcrumb($breadcrumb) {
 
	if (arg(0) == 'taxonomy' && arg(1) == 'term') {		
	$tid = arg(2);
	$term = taxonomy_get_term($tid);
	$vocabulary = taxonomy_vocabulary_load($term->vid);
	$vterms = taxonomy_get_tree($term->vid);
	$vitems = '';
	foreach ( $vterms as $vterm ) {
		$vitems .= "&#43;".$vterm->tid;
	}
 
		$breadcrumb[] = l($vocabulary->name, 'taxonomy/term/'.$vitems);
	  $breadcrumb[] = l($term->name, 'taxonomy/term/'.$term->tid);
  }
  if (count($breadcrumb) > 1) {
    // $breadcrumb[] = drupal_get_title();
    if ($breadcrumb) {
      return '<div class="breadcrumb">'. implode(' &rsaquo; ', $breadcrumb) ."</div>\n";
    }
  }
}
?>
