Request callback validation example
<?php
/**
* Implementation of hook_menu().
*/
function ssp_menu($may_cache){
$items = array();
$items[] = array(
'path' => 'validate/user/'.arg(2),
'title' => t(''),
'callback' => 'ssp_validate_user',
'callback arguments' => array(arg(2)),
'access' => TRUE,
);
return $items;
}
/**
* Implementation of hook_form_alter();
*/
function ssp_form_alter($form_id, &$form){
if ($form_id == 'user_login' || $form_id == 'user_login_block'){
// We want the username to have a validation type of request
$form['name']['#attributes']['class'] = 'request';
// and we want the path to be /validate/user (an additional argument of the value is passed)
$form['name']['#attributes']['validator-path'] = '/validate/user';
}
}
function ssp_validate_user($username){
$output = array();
$username = check_plain($username);
if ($user = user_load(array('name' => $username))){
// user is found
$output['valid'] = TRUE;
}
else {
// user is not found, provide an error message.
$output['valid'] = FALSE;
$output['message'] = t('Sorry the user <strong>!username</strong> was not found.', array('!username' => $username));
}
// format the $output array as a javascript readable object which is then displayed, and
// then we exit; to display only this JSON string on the page being requested by the javascript.
echo json_encode($output);
exit;
}
