I have a form in index.php

<?php 
  echo '<form action="update_act.php" method="POST">';
  echo '<input type="submit" name="'.$row['act_name'].'" value="edit">
  echo </form>
?>

Here $row['act_name'] is a value fetched from database.

My update_act.php file is

<?php
   echo "Old Activity Name : ".$_POST['$row[\'act_name\']'];
?>

But I am getting an error Undefined index: $row['act_name'] in C:\wamp\www\ps\activity\update_act.php.

I want to have different names for different submits but I am not able to get its value in another page. Is there any way for it?
