No Objects

DB Layer

• Uses straight SQL queries

• db_query() and db_query_range()

• db_fetch_object() or db_fetch_array()

• drupal_write_record()

function ahah_callback_method() { // AHAH processing prep $form_state = array('storage' => NULL, 'submitted' => FALSE); $form_build_id = $_POST['form_build_id']; $form = form_get_cache($form_build_id, $form_state);

/** * Given a POST of a Drupal form (with both a form_build_id set), this * function rebuilds the form and then only renders the given form item. If no * form item is given, the entire form is rendered. * * Is used directly in a menu callback in ahah_helper's sole menu item. Can * also be used in more advanced menu callbacks, for example to render * multiple form items of the same form and return them separately. * * @param $parents */function ahah_helper_render($form_item_to_render = FALSE) { $form_state = array('storage' => NULL, 'submitted' => FALSE); $form_build_id = $_POST['form_build_id'];

// Get the form from the cache. $form = form_get_cache($form_build_id, $form_state); $args = $form['#parameters']; $form_id = array_shift($args);

// Are we on the node form? $node_form = FALSE; if (preg_match('/_node_form$/', $form_id)) { $node_form = TRUE; module_load_include('inc', 'node', 'node.pages'); }

// We will run some of the submit handlers so we need to disable redirecting. $form['#redirect'] = FALSE; // We need to process the form, prepare for that by setting a few internals // variables. $form['#post'] = $_POST; $form['#programmed'] = FALSE; $form_state['post'] = $_POST;

// $form_state['storage']['#ahah_helper']['file'] has been set, to know // which file should be loaded. This is necessary because we'll use the form // definition itself rather than the cached $form. if (isset($form_state['storage']['#ahah_helper']['file'])) { require_once($form_state['storage']['#ahah_helper']['file']); }

// If the form is being rebuilt due to something else than a pressed button, // e.g. a select that was changed, then $_POST['op'] will be empty. As a // result, Forms API won't be able to detect any pressed buttons. Eventually // it will call _form_builder_ie_cleanup(), which will automatically, yet // inappropriately assign the first in the form as the clicked button. The // reasoning is that since the form has been submitted, a button surely must // have been clicked. This is of course an invalid reasoning in the context // of AHAH forms. // To work around this, we *always* set $form_state['submitted'] to true, // this will prevent _form_builder_ie_cleanup() from assigning a wrong // button. When a button is pressed (thus $_POST['op'] is set), then this // button will still set $form_state['submitted'],

// $form_state['submit_handlers'] and $form_state['validate_handlers']. // This problem does not exist when AHAH is disabled, because then the // assumption is true, and then you generally provide a button as an // alternative to the AHAH behavior. $form_state['submitted'] = TRUE; // Continued from the above: when an AHAH update of the form is triggered // without using a button, you generally don't want any validation to kick // in. A typical example is adding new fields, possibly even required ones. // You don't want errors to be thrown at the user until they actually submit // their values. (Well, actually you want to be smart about this: sometimes // you do want instant validation, but that's an even bigger pain to solve // here so I'll leave that for later…) if (!isset($_POST['op'])) { // For the default "{$form_id}_validate" and "{$form_id}_submit" handlers. $form['#validate'] = NULL; $form['#submit'] = NULL; // For customly set #validate and #submit handlers. $form_state['submit_handlers'] = NULL; $form_state['validate_handlers'] = NULL; // Disable #required and #element_validate validation. _ahah_helper_disable_validation($form); }

// Build, validate and if possible, submit the form. drupal_process_form($form_id, $form, $form_state); if ($node_form) { // get the node from the submitted values $node = node_form_submit_build_node($form, $form_state);

// hack to stop taxonomy from resetting when the form is rebuilt $form_state['node']['taxonomy'] = taxonomy_preview_terms($node); }

// This call recreates the form relying solely on the form_state that the // drupal_process_form set up. //$form = drupal_rebuild_form($form_id, $form_state, $args, $form_build_id); $form = drupal_rebuild_form($form_id, $form_state, $args, $form_build_id);

// Get the form item we want to render. $form_item = _ahah_helper_get_form_item($form, $form_item_to_render);
