    plugin index.php:

    <?php
    /*

    */
    ?>
    <!--<script type="text/javascript">
    
    function formValidator(forme)
    {
    
    	var limit = document.getElementById('txtlimit').value;
    	var seck = document.getElementById('txtkey').value;
    	var interval = document.getElementById('txtinterval').value;
    
    }
    
    </script>-->
    
    <?php
    add_action('admin_menu', 'basicPluginMenu');
    function basicPluginMenu() {
    $appName = 'Dhundora';
    $appID = 'basic-plugin';
    add_menu_page($appName, $appName, 'administrator', $appID, 'pluginAdminScreen');
    }
    function pluginAdminScreen() {
    
    	  global $current_user;
          get_currentuserinfo();
    
           $userlog=  $current_user->user_login ;
    
    	echo '<h1> Welcome to Dhundora Advertising Script</h1>';
    	?>

    <input id="login-submit" name="Continue" type="submit" value="Register" style="padding:8px"/>
    </form>
    <div id="result">
    <?php
    $data = array();
    $myFile = "../wp-content/plugins/dhundora/".$userlog.".txt";
    $fh = fopen($myFile, 'a+') or die("No Settings Saved");
    $i = -1;
    //Output a line of the file until the end is reached
    while(!feof($fh))
      {
    	  $i = $i+1;
      $data[$i] = fgets($fh);
      }
    fclose($fh);
    
    echo  '<br /><br />'.'<input type="text" readonly="readonly" value =  '.$data[0]. ' /><br />';
    echo  '<br /><br />'.'<input type="text" readonly="readonly" value =  '.$data[1]. ' /><br />';
    echo  '<br /><br />'.'<input type="text" readonly="readonly" value =  '.$data[2]. ' /><br />';
    
    ?>
    </div>
    
    <?php
    
    }
    
    ?>

    and the form submittion file process-file.php

    <?php
    
    /*$userlim =  $_GET['userlimit']."\n";
    $userint =  $_GET['userinterval']."\n";
    $userkey = $_GET['userkey']."\n";
    */
    $myFile = $_GET['username'].".txt";
    $fh = fopen($myFile, 'w+') or die("can't open file");
    
    $stringData = $userkey = $_GET['userkey']."\n".$_GET['userlimit']."\n".$_GET['userinterval']."\n";
    fwrite($fh, $stringData);
    fclose($fh);
    
    ?>
