In this snippet, I'll show you how you can submit a webform programmatically using drupal_execute(). The first thing you'll need to do is figure out what the $form_state data looks like when the webform is submitted, so you can recreate that structure and pass it into drupal_execute().

One way to accomplish this is to add a validation/submit handler to the form using hook_form_alter() and then output the contents of the submitted data (using krumo, print_r, etc).

The following code will prepend a validation handler to the webform $form, so we can dump the submitted data to the screen:

<?php
function MYMODULE_form_alter(&$form, $form_state, $form_id) {
 
 
// define node id of webform
 
$webform_node_id = 146;
 
 
// check for form id of webform
 
if ($form_id == 'webform_client_form_' . $webform_node_id) {
 
   
// prepend a validation callback to the form
   
array_unshift($form['#validate'],
     
'_MYMODULE_form_alter_webform_' . $webform_node_id . '_validate');
 
  }
 
}
?>

And here is the validation handler which will dump the submitted data to the screen. NOTE: krumo() is available from the devel module; you could use print_r() as well:

<?php
function _MYMODULE_form_alter_webform_146_validate($form, &$form_state) {
 
// debug
 
krumo($form_state);
  die;
}
?>

Now, if I populate the webform with some data:

And submit the form, I will get the following debug output:

You'll need to mirror the structure of the submitted data when creating your $form_state variable, which will be passed into drupal_execute().

In the following function, I show how you can submit a webform programmatically. There is even additional code in there which loads a user's previously submitted data, if you care.

<?php
function MYMODULE_some_function() {

 
// define webform node id
 
$webform_node_id = 146;

 
// define user submitting the webform
 
$user_id = 2;

 
// load webform node
 
if ($node = node_load($webform_node_id)) {

   
// load module include file, per loading previously submitted webform data
   
module_load_include('inc', 'webform', 'webform_report');

   
// get submissions for user
   
$submissions = webform_get_submissions($node->nid, NULL, $user_id);

   
// get submission data ($submission) and submission id ($sid)
   
if (FALSE !== ($sid = key($submissions))) {
     
$submission = $submissions[$sid];
    }
    else {
     
$submission = NULL;
     
$sid = NULL;
    }

   
// create array of $form_state data
    // NOTE: be sure to use the debug output as a guide to make this array match!
   
$form_state = array(
     
'submitted' => true,
     
'values' => array(
       
'submission' => $submission,
       
'submitted' => array(
         
'test_field_1' => 'abc',
         
'test_field_2' => '123',
         
'test_field_3' => 'def',
        ),
       
'details' => array(
         
'email_subject' => $node->webform['email_subject'],
         
'email_from_name' => $node->webform['email_from_name'],
         
'email_from_address' => $node->webform['email_from_address'],
         
'nid' => $webform_node_id,
         
'sid' => $sid,
        ),
       
'op' => t('Submit'),
       
'submit' => t('Submit'),
       
'form_id' => 'webform_client_form_'. $webform_node_id,
      ),
    );

   
// Saves the webform data submited prior to login.
   
drupal_execute('webform_client_form_'. $webform_node_id, $form_state, $node, $submission, TRUE, FALSE);
   
  }

}
?>

In this tutorial I'll show how you can programmatically and dynamically remove a column from your view. In my example, I chose to hide an email column from unauthenticated users, but you could apply this code to do pretty much anything.

To get things started, I defined a content type of "Profile" to contain some user details (using the Content Profile module) and used the Devel module's generate users and nodes functionality to create some sample data. I then created a view to show the data:

Here is my page view display:

Now you can add the hook_views_pre_build() function in your module. Since the $view object is large, I recommend using krumo() (which comes with the Devel module) to browse through the $view object's properties.

<?php
function MYMODULE_views_pre_build(&$view) {

 
// check for your view name (in my example: people)
 
if ($view->name=='people') {
   
krumo($view);
  }

}
?>

The above code will neatly format the $view object in a hierarchical display. You can click to expand each class property.

As you can see, the $view object has a lot of data in it. At this point, you'll need to get acquainted with the structure of the handler object of the view ($view->display['default']->handler) and determine what to modify. To remove the email column for unauthenticated users, you can add the following code:

<?php
function MYMODULE_views_pre_build(&$view) {

 
// check for your view name (in my example: people)
 
if ($view->name=='people') {
  
   
// check if the user is anon
   
if (in_array('anonymous user',$GLOBALS['user']->roles)) {

     
// remove view hander properties for email column
     
unset(
       
$view->display['default']->handler->options['fields']['mail'],
       
$view->display['default']->handler->options['style_options']['columns']['mail'],
       
$view->display['default']->handler->options['style_options']['info']['mail']
      );

    }

  }

}
?>

When I logout, my view no longer shows the email column:
