Thanks Ben! So I added the code your provided to the general.php file, and then added this to the php file I want to display the info:

Code:

<?php require_once('/path/to/global/library.php');
ft_include_module("submission_history");
$form_id = form_16;
$submission_id = id;
$last_modified_info = sh_get_last_modified_info($form_id, $submission_id);
?>

(I updated the path, and the form_id to the correct value. "id" will be obtained from the url, test.php?id=1)

So, there are no errors on the page. yay! But now to print the info I need on the page...so I would assume

Code:

echo $last_modified_info["first_name"];

Of course, with my limited (but learning!) php knowledge, I have missed something.. because nothing is displayed :-)

Hey Alex,

Sorry! Brain like a sieve.

Here: just add this function to the bottom of your /modules/submission_history/code/general.php file:

PHP Code:

/**
 * This returns information about who last modified the submission. Added in 1.1.2.
 *
 * @param integer $form_id
 * @param integer $submission_id
 * @return array has_history  - true/false
 *               account_type - admin/client/unknown
 *               account_id   - the ID of the admin/client
 *               first_name   - the admin/client last name
 *               last_name    - the admin/client last name
 */
function sh_get_last_modified_info($form_id, $submission_id)
{
  global $g_table_prefix;

  $query = mysql_query("
    SELECT sh___change_account_type, sh___change_account_id
    FROM   {$g_table_prefix}form_{$form_id}_history
    WHERE  submission_id = $submission_id
    ORDER BY     sh___history_id DESC
    LIMIT 1
  ");

  $return_info = array("has_been_modified" => false);
  if (mysql_num_rows($query) == 0)
  {
    return $return_info;
  }

  $result = mysql_fetch_assoc($query);
  $return_info = array(
    "has_been_modified" => true,
    "account_type"      => $result["sh___change_account_type"],
    "account_id"        => $result["sh___change_account_id"]
  );

  if (is_numeric($result["sh___change_account_id"]))
  {
    $account_info = ft_get_account_info($result["sh___change_account_id"]);
    $return_info["first_name"] = $account_info["first_name"];
    $return_info["last_name"] = $account_info["last_name"];
  }

  return $return_info;
} 


Then, to call it, just add this code to your PHP page (the first line is only necessary if you haven't already included the API or library.php file):

PHP Code:

require_once('path/to/global/library.php');
ft_include_module("submission_history");
$form_id = 123;
$submission_id = 456;
$last_modified_info = sh_get_last_modified_info($form_id, $submission_id); 


Then, $last_modified_info contains all the important details about who last modified it.

Here's what it contains:

PHP Code:

// boolean. This will contain "true" if there's a record in the history table; false otherwise.
$last_modified_info["has_been_modified"];

// *** the following keys are only populated if has_been_modified == true

// string. this contains "admin", "client" or "unknown"
$last_modified_info["account_type"];

// integer. This only has a value if account_type == "admin" or "client"
$last_modified_info["account_id"];

// strings. These are only populated if account_type == "admin" or "client"
$last_modified_info["first_name"];
$last_modified_info["last_name"]; 


Let me know how it goes. If all looks good, I'll add it to the next version of the module!
