Hi,

i am using webform module to create a free signup form.
So authenticated and anonymous user can signup for the event.
Once a user signed up, an email will sent to user.
In that email there is an unregister link , once they click , they will be able to see their submission and a button to unregister.
If you look into the url of unregister you will be able to see url like http://localhost/eve/node/5/submission/5/unregister
if an anonymous user change it into 4 he will be able to access others submission.How can i hash the url .
Please see the attachments

Hi Robert,

As i was looking for a solution , I created an access called unregister submission.So whenever user submitted a form (anonymous user too), a hashed value will store in database. The hashed value is md5 of the time and ip addres. Now i am trying to append the hash value to the url of unregister.The codes i created was given below.Please look into this and give me a suggestion .

Database Change
------------------------------
In schema webform_submissions add a varchar for hash value

'hash_value' => array(
'description' => 'The hash value for user submission.',
'type' => 'varchar',
'length' => 128,
),

Webform_submissions.inc
------------------------------------------
Insert hashed values into database
In function webform_submission_insert($node, $submitted)

$hash_value = md5(time().ip_address());
$result = db_query("INSERT INTO {webform_submissions} (nid, uid, submitted, remote_addr, hash_value) VALUES (%d, %d, %d, '%s')", $node->nid, $user->uid, time(), ip_address(), $hash_value);

Webform.module
---------------------------
In node submissions, add for unregister

$items['node/%webform_menu/submission/%webform_menu_submission/unregister/%hash_value'] = array(
'title' => 'Unregister',
'load arguments' => array(1),
'page callback' => 'drupal_get_form',
'page arguments' => array('webform_submission_unsregister_form', 1, 3,5),
'access callback' => 'webform_submission_access',
'access arguments' => array(1, 3,5, 'unregister'),
'weight' => 3,
'type' => MENU_LOCAL_TASK,
);

In function webform_submission_access

case 'unregister':
return user_access('unsregister own webform submissions');

In function webform_perm()
'unsregister own webform submissions',

In function webform_access($op, $node, $account)
case 'unregister':
return user_access('unsregister own webform submissions', $account);

Thank You
