function template_preprocess_theming_example_text_form
Implements template_preprocess().
We prepare variables for use inside the theming-example-text-form.tpl.php template file.
In this example, we create a couple new variables, 'text_form' and 'text_form_content', that clean up the form output. Drupal will turn the array keys in the $variables array into variables for use in the template.
So $variables['text_form'] becomes available as $text_form in the template.

function template_preprocess_theming_example_text_form(&$variables) {
$variables['text_form_content'] = array();
$text_form_hidden = array();
// Each form element is rendered and saved as a key in $text_form_content, to
// give the themer the power to print each element independently in the
// template file. Hidden form elements have no value in the theme, so they
// are grouped into a single element.
foreach (element_children($variables['form']) as $key) {
$type = $variables['form'][$key]['#type'];
if ($type == 'hidden' || $type == 'token') {
$text_form_hidden[] = drupal_render($variables['form'][$key]);
}
else {
$variables['text_form_content'][$key] = drupal_render($variables['form'][$key]);
}
}
$variables['text_form_content']['hidden'] = implode($text_form_hidden);
// The entire form is then saved in the $text_form variable, to make it easy
// for the themer to print the whole form.
$variables['text_form'] = implode($variables['text_form_content']);
