Our example: we try to set the default value for a filter on a certain week.
I tried to set the default value of your exposed filter in:
<?php
$form['week']['#default_value'];
?>Didnt work.
In get forms you need to set the $form_state['input']['week']. Also you need to make sure the value isnt submitted yet so check on $_GET['week'] to get the actual value.
Here is a code example
<?php
/**
* Implementation of hook_form_alter()
*/
function boek_top100_form_alter(&$form, &$form_state, $form_id) {
//Sets the default top 100 week ie. the latest
if ($form_id == 'views_exposed_form' && arg(0) == 'top100') {
$result = db_result(db_query("SELECT week FROM {boek_top100} ORDER BY id DESC LIMIT 1"));
if ($_GET['week'] == '') {
$form_state['input']['week'] = $result;
}
}
}
