   I have searched for the answer to this for the last hour. I am sure it is here somewhere, I must just not be looking in the right place. I must say here that I am new to wordpress and php.

   I have created a plugin that requires users to enter data, so I have a seperate php file that is called and shows the form, and also processes the submission. The issue is that I need to access the current user name when processing: and I can't figure out how. I am thinking "get_currentuserinfo();", but I can't seem to figure out how to get access to that.

   Thanks for any help you can provide.

   Below is the php file

   br />
   <?php

   if (array_key_exists('_submit_check', $_REQUEST)) {
   $aa = !empty($_REQUEST['a_a']) ? $_REQUEST['a_a'] : '';
   $bb = !empty($_REQUEST['b_b']) ? $_REQUEST['b_b'] : '';
   echo $aa;
   echo $bb;
   } else {
   wp_show_page();
   }

   function wp_show_page()
   {
   global $userdata;
   get_currentuserinfo();

   echo('Username: ' . $userdata->user_login . '\n');
   echo('User level: ' . $userdata->user_level . '\n');
   echo('User ID: ' . $userdata->ID . '\n');
   ?>
   <form name="linkform" id="linkform" class="wrap" method="post" action="/wp-content/plugins/subm.php">
   <input type="hidden" name="_submit_check" value="1"/>
   <div style="float: left; width: 98%; clear: both;" class="top">
   <fieldset class="small"><legend>Add new</legend>
   <table>
   </table>
   </fieldset>
   <input type="submit" name="save" class="button bold" value="Save »" />
   </div>
   <div style="clear:both; height:1px;"> </div>
   </form>
   <?php
   }

   ?>

   get_currentuserinfo() sets a number of global variables. You can see them all in the function at line 34 in /wp-includes/pluggable-functions.php

   For your convenience, here they are:
   $user_login = $_COOKIE[USER_COOKIE];
$userdata = get_userdatabylogin($user_login);
$user_level = $userdata->user_level;
$user_ID = $userdata->ID;
$user_email = $userdata->user_email;
$user_url = $userdata->user_url;
$user_pass_md5 = md5($userdata->user_pass);
$user_identity = $userdata->display_name;

   To use any of these, you must make them global, like this:
   global $user_identity;
get_currentuserinfo();
if ('' != $user_identity) {
echo "Hi there, $user_identity!";
}

   I've done that, (as you can see at the top of my function wp_show_page()). But I get "Call to undefined function: get_currentuserinfo()". So I think that I need to get access to the WP context somehow. I imagine it is a require_once statement that I am missing, but requiring various things hasn't worked for me. It can never find the files that I require.

   I looked at the wp-contact-form, and it specifically says that it doesn't have access to the wp functions. So I am not sure if it is even possible. Anyone have any idea what to do?
