I needed a way for a user to be prompted to send a message to the author of a node after it was flagged. This was my solution.
jQuery Impromptu provides a nice way of implementing a pop-up feature.
Flag of course flags a node.
<?php
// Load necessary to avoid error
module_load_include('pages.inc','privatemsg');
// Adds javascript to header
jquery_impromptu_add();
// Gets rid of whitespaces that break javascript code
// drupal_get_form retrieves the privatemsg form
// $uid is the author of the node
// $title is the title of the node
$form = str_replace("\r", '', str_replace("\n", '', drupal_get_form('privatemsg_new', $uid, $title)));
// javascript that runs jquery_impromptu on flag event
print '<script language="javascript">';
print "
$(document).bind('flagGlobalAfterLinkUpdate', function(event, data) {
if(data.flagStatus == 'flagged'){
$.prompt('$form');
}
});
";
print '</script>';
// Necessary because previous module_load_include changes title
drupal_set_title(check_plain($node->title));
?>
