<form id="form1" name="form1" method="post" action="news_add_save.php">
          <table width="560" height="173" border="0" cellpadding="0" cellspacing="0" class="input">

              <td width="114">หัวข้อข่าว</td>
              <td width="446"><input name="txt_title" id="txt_title" type="text"  size="70" /></td>
            </tr>
            <tr>

          </table>
        </form>

<?php
	include 'connect.php';
	$name	= $_POST['txt_title'];
	$text   = $_POST['txt_detail'];	
	$date       =date("Y-m-d"); 
		
	$sql	= "INSERT INTO news (title,detail,date_post) VALUES ";
