Examples we used:
Example 1:
between the php tags:
$result = taxonomy_select_nodes( array(1, 3), 'or', 'all', true);
$html = node_title_list($result);
$html.= theme('pager');
print $html;
Example 2:
between the php tags:
$node = node_load(55); $i=$_GET['choice']; print $node->choice[$i]['chvotes'];
and add to the url:
?choice=1
Example 3:
between the php tags:
$node = node_load(55); $i=arg(2); print $node->choice[$i]['chvotes']."<br />"; print arg(0)."<br />"; print arg(1)."<br />"; print arg(2)."<br />"; print arg(3);
and add to the url:
/0
Functions that we used in the 2nd session:
Drupal functions:
- taxonomy_select_nodes()
- node_title_list()
- theme()
- theme_pager()
- any drupal function that starts with theme_ is called a themeable function, i.e. it can be overridden in every theme folder (any theme can write its own html output for these variables, in our example it was the pager).
- arg()
PHP functions:
- array()
HTTP variables:
- _GET
- for getting data from the database
- usually the URL changes, so that u can use the same URL to GET the same data (results) if used at other times.
- _POST
- for submitting/sending data to the database, e.g. in forms
