Sorry if this sounds like a noob question ( ), but how would I go about retrieving data POSTed from a text input field (sample below), update the respective row (WHERE id=1 for example) and then display the data in the same input fields again for ease of editing (all-the-while using PDO of course )? <form action="form.php" method="POST"> <input type="text" name="header1" placeholder="Header text here"> <textarea name="summary1" placeholder="Summary text here"> <input type="submit" name="submit" value="Update Info"> </form>
