Drupal 7 Module Development

Installation Profiles
Text filters
Text filters, known as input formats in previous versions of Drupal, are created
and configured by the installation profile. In order for a site to have text filters
that users can choose from, the installation profile must set up the filter first. The
simplest method for setting them up is in the hook_install() function inside the
profile's .install file. Continuing our example, the following code at the top of
store_install() would add Filtered HTML and Full HTML text filters, with the
filtered one set as the default:
// Add text formats.
$filtered_html_format = array(
'format' => 'filtered_html',
'name' => 'Filtered HTML',
'weight' => 0,
'filters' => array(
// URL filter.
'filter_url' => array(
'weight' => 0,
'status' => 1,
),
// HTML filter.
'filter_html' => array(
'weight' => 1,
'status' => 1,
),
// Line break filter.
'filter_autop' => array(
'weight' => 2,
'status' => 1,
),
// HTML corrector filter.
'filter_htmlcorrector' => array(
'weight' => 10,
'status' => 1,
),
),
);
$filtered_html_format = (object) $filtered_html_format;
filter_format_save($filtered_html_format);
$full_html_format = array(
'format' => 'full_html',
'name' => 'Full HTML',
'weight' => 1,
'filters' => array(
