The AHAH Helper module eases the work when developing AHAH powered forms. More information about the AHAH Helper can be found here.
An example of a problem can be when creating a form that initially displays a drop-down and a submit button. When a user selects on of the valid options, another drop-down is displayed with additional options which is associated with what the user has selected. The solution to this problem is the code shown below.
function MY_MODULE_NAME_ahah_powered_form($form_state) {
$form = array();
/* register your form */
ahah_helper_register($form, $form_state);
if(!isset($form_state['storage']['classification']['type'])) {
$type_default_value = 0;
} else {
$type_default_value = $form_state['storage']['classification']['type'];
}
if(!isset($form_state['storage']['classification']['animal'])) {
$animal_default_value = 0;
} else {
$animal_default_value = $form_state['storage']['classification']['animal'];
}
/* sample drop-box options */
$type_options = array(
0 => 'Choose Animal Type',
1 => 'Invertebrates',
2 => 'Vertebrates'
);
$animal_options[1] = array(
0 => 'Choose Animal',
3 => 'Mollusks',
4 => 'Arthropods'
);
$animal_options[2] = array(
0 => 'Choose Animal',
5 => 'Fish',
6 => 'Amphibians'
);
$form['classification'] = array(
'#type' => 'fieldset',
'#title' => t(''),
'#prefix' => '',
/* Don't forget to set #tree! */
'#tree' => TRUE,
);
$form['classification']['type'] = array(
'#type' => 'select',
'#title' => '',
'#default_value' => $type_default_value,
'#options' => $type_options,
'#ahah' => array(
'event' => 'change',
'wrapper' => 'classification',
/* This is the "magical path". Note that the parameter is an array of
the parents of the form item of the wrapper div! */
'path' => ahah_helper_path(array('classification')),
),
);
/* display if user has selected animal type */
if($type_default_value) {
$form['classification']['animal'] = array(
'#type' => 'select',
'#title' => '',
'#default_value' => $animal_default_value,
'#options' => $animal_options[$type_default_value],
);
}
$form['classification']['go'] = array(
'#type' => 'submit',
'#value' => t('Go'),
);
return $form;
}

yum install rsync
Once Rsync is installed. You can type rsync -man to see all the options available to it. Here is an example of Rsync:
rsync -r -v username@servername.com:/var/www/vhosts/site1/ /var/www/vhosts/site2
This example will merge the code from site1 on the remote server to site2 on my local. Using the -v specifies verbose and -r is recursive.
rsync -r -v --exclude “sites/default/files” username@servername.com:/var/www/vhosts/site1/ /var/www/vhosts/site2
This example will merge the code from site 1 to site2 but will also exclude the directory “sites/default/files”.
