Question

I am absolute beginner to drupal.

I have added a contact form (using Webform module).

Now I want to save the data entered in the form. But I am lost. I have searched over internet, found db_query() is used to query database.

But I dont know where to write the php code. Please help me or if you know any link,please give me.

The tables you’ll be most interested in are webform, webform_submissions, webform_submitted_data and webform_component. Have a look at those tables and it becomes very obvious how they’re linked together.

You’ll want to look at the Drupal 7 Database API to learn how to use the query system but here’s an example to get you going:

/* Get a list of all submissions from webform for the node with ID (`nid`) of 1 */
$nid = 1;
$submissions = db_select('webform_submissions', 'ws')
  ->fields('ws')
  ->condition('nid', $nid)
  ->execute();

/* If you want to use db_query and a plain old SQL statement instead you'd do it like this: 
$submissions = db_query('SELECT * FROM webform_submissions WHERE nid = :nid', array('nid' => $nid)); */

/* Loop through the submissions and load up the submitted data for each */
$submission_data = array();
foreach ($submissions as $submission) {
  $query = db_select('webform_submitted_data', 'wsa')
    ->fields('wc', array('name'))
    ->fields('wsa', array('data'))
    ->condition('sid', $submission->sid);

  /* Join in the component table to get the element label */
  $query->join('webform_component', 'wc', 'wc.nid = wsa.nid AND wc.sid = wsa.cid');

  $submission_data[] = $query->execute()->fetchAllKeyed();

}

At the end of that code you’ll have an array ($submission_data), which contains a list of arrays of submission data for the provided node. Each of those arrays’ items has a key of the component label, and a value of the submitted user value.

Hope that helps
