As a small note to dynamic filters, for example:
<?php$my_view = views_get_view('my_name');
$my_view->filter[1]['value'] = 1;
$my_view->is_cacheable = 0;
?>
Always use
<?php $my_view->is_cacheable = 0;?>after adding filters, fields, arguments or anything dynamically to a view.Handy trick to turn views exposed filters into dropdowns/selects fields.
I tried to override the
views-exposed-form.tpl.phpby using functionMYTHEME_preprocess_views_exposed_form(&$vars, $hook)but that never actually worked. The changes were not being printed out, the form was never altered.Then I implemented "hook_form_FORM_ID_alter" to convert a textfield exposed filter into a dropdown or select field, I created a custom module and implemented the hook_form_FORM_ID_alter as follows:
<?php
function mymodule_form_views_exposed_form_alter(&$form, &$form_state)
{
if($form['#id'] == 'views-exposed-form-myviews-page-1')
{
unset($form['title']);
// this part is very important to avoid "illegal choice"
// error message.
$options[""] = t("Any");
$result = db_query("SELECT title FROM {node}");
while($r = db_fetch_array($result))
{
$options[check_plain($r['title'])] = $r['title'];
}
$form['title']['#type'] = 'select';
$form['title']['#options'] = $options;
$form['title']['#multiple'] = false;
}
}
?>
