How to use a drupal_mail function.

Let's say you want to send mail using drupal_mail function in your "test" custom module (test is an example name of module used below) after the form is submitted. You have to build two functions. First is a test_form_submit function, the second one is the test_mail function.

In the submit function you have to put the code below:

<?php

function test_form_submit($form, &$form_state) {

$to = "test@example.com"; // to e-mail address
$from = "test@example.com"; // from e-mail address

I've seen a hundred times when people was looking for a function that displays all the menu tree (including children) with all its parameters. This little function makes drop down menu available. The function that returns all the arrays of menu is:

menu_tree_all_data($menu_name);

Let's say you want to display all array of primary-links with it's children. Just write:

print_r(menu_tree_all_data('primary-links'));

Having this information is a good start to write a module that allows to display drop down menu.

If you need to change mysql tables prefix just run the script below:

<?php
 $a = ''; // here goes old current prefix
 $b = ''; // here goes a new prefix

 $result = db_query("SHOW TABLES");
  while ($r = db_fetch_array($result)) {
   $table_old = current($r);
   $table_new = str_replace($a, $b, $table_old);
   db_query("RENAME TABLE {$table_old} TO {$table_new}");
   print "{$table_old} —> {$table_new} 
";
  }
?>

Of course you need to have mysql connection established at first.

Alright, so few days ago I had to set up the big background to my xhtml page. As always I put this code:

body { 

background: url('img/bg_body.jpg') no-repeat top center;
display: table; 
width: 100%; 

}

Drupal Api site gives only a quick description of avaliable functions. In most cases there's no examples of usage. save_node function is so important that I have to give a working example with CCK fields. Here it is:

Here is saving new node:

<?php
// add node properties
$newNode = (object) NULL;
$newNode->type = '{NODE_TYPE}';
$newNode->title = '{NODE_TITLE}'
$newNode->uid = {USER_ID};
$newNode->created = strtotime("now");
$newNode->changed = strtotime("now");
$newNode->status = 1;
$newNode->comment = 0;
$newNode->promote = 0;

In the htaccess file just replace this code:


RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} !=/favicon.ico
RewriteRule ^(.*)$ index.php?q=$1 [L,QSA]


to:


RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} !=/favicon.ico
RewriteRule ^(.*)$ index.php?q=$1 [L,QSA]


There are a lot of forum posts and issue queues revolving around the need to use a newer version of jQuery on a Drupal 6.x site. There are several ways to achieve this, such as using the jQuery Update module, but I'm going to focus on the recommended method of running 2 versions of jQuery side-by-side - the jQuery noConflict() function.

If you want to show a block only to a specyfic user change option in "Show block on specific pages:" area to "Show if the following PHP code returns TRUE (PHP-mode, experts only)." and paste the code shown below:

<?php
global $user;
if ($user->uid == 1){
  return TRUE;
} else {
  return FALSE;
}
?>

The only thing to chagne in the code is the user ID that in the example above equals "1".

That's it :)

Put this code to template.php. After that just clear cache in admin/settings/performance.

<?php

function themename_links($links, $attributes = array('class' => 'links')) {
  global $language;
  $output = '';

  if (count($links) > 0) {
    $output = '';

    $num_links = count($links);
    $i = 1;

    foreach ($links as $key => $link) {
      $class = $key;

      // Add first, last and active classes to the list of links to help out themers.
      if ($i == 1) {
        $class .= ' first';
      }
