Styling PDF generated file using Print Module, CSS and TCPDF is a little tricky. Becouse I had to face it there are few issues that you must notice. First of all if you want to use external css in most cases it won't work as a file. Better approach is to create a file print_pdf.tpl.php in your theme directory and attach an inline css. Do not put the css in your head tag as it is in standard html. Put it in body section, right after body tag starts like this:

<%body>

Easy, that's how:

<?php

//nice menus display

$menu = theme('nice_menus', array('id' => 0, 'direction' => 'down', 'depth' => 1, 'menu_name' => 'main-menu', 'menu' => NULL));

print $menu['content'];

?>

If you would like to display custom content on given time just use the script below. All explanations were included in comments of script:

<?php


// date format eg. 01-03-2012 00:01
function showOnTime($givenDate, $content) {

	$now = time(); //returns timestamp of current time 
	$givenDate = strtotime($givenDate); //returns timestamp of given date
	
	if($now >= $givenDate) { //if now variable exceeds givenDate the content is displayed
	
		print $content;
	
	}
}

//example of usage

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]
