        <div class="form-group"> <strong>Projects In Progress :</strong><input type="text" class="form-control" name="done" value="<?php echo $row['projects_running']?>"> </div>        
        <a class="btn btn-primary"   href="about-us.php?update">Update</a>
    </form>
    <?php 
        }

    else{?>
        <a  class="btn btn-default pull-right" href="about-us.php?edit" name="edit">Edit</a>
        <h1>About us </h1>
        <?php 
            echo '<p>'.$row['content'].'</p>';
            echo  '<p><strong>Projects Completed :</strong>' .$row['projects_completed'].'</p>';
            echo  '<p> <strong>Projects Completed :</strong>' .$row['projects_running'].'</p>';
        ?>
    <?php };


?>

<?php if (isset($_GET['update'])) {
      $name= $_GET['content'];
      echo $name; 
?>

this is the error i get

Notice: Undefined index: content in C:\wamp\www...

Please help me to fix this ,

Where is the initialization of variable $row? I think you need echo $_GET['content']; and not echo $row['content']; — Kostas Mitsarakis, Nov 21 '15 at 20:15
that's above in loop , i'm etching data properly issue comes when i press update — Sikander, Nov 21 '15 at 20:16
It does not look like you are submitting a form, but just clicking on a link `Update`. — Sean, Nov 21 '15 at 20:18
1st - fix the error that @chris85 points out in [this comment](http://stackoverflow.com/questions/33848098/php-undefined-index-error-while-updating-database#comment55460850_33848098). 2nd - forms are submitted with either a `` or ` — Sean, Nov 21 '15 at 20:22

The notice messsage you see says that the array $_GET has not a content index. You can do something like that:

if (key_exists('content', $_GET)) {...} else {...}

instead of

if (isset($_GET['update'])) ...
