Question

請幫我什麼是查詢波紋管

代碼的問題： -

error_reporting(E_ALL^E_NOTICE); 
require('../../conn/include.php'); 

$sel="SELECT * from `activites` where act_id='".$_REQUEST['doo']."'"; 
$query=mysql_query($sel); 
$reader=mysql_fetch_array($query); 


$title=$_POST['tit']; 
$descrip=$_POST['description']; 
$project=$_POST['project']; 
$visibality=$_POST['vasiblity']; 

if(isset($_REQUEST['update'])) 
{ 

$updat="UPDATE `my`.`activites` SET `title`='$title',`description`='$descrip',`project`='$project',`published` ='$visibality' WHERE `activites`.`act_id` ='".$_REQUEST['doo']."'"; 

    $que=mysql_query($updat); 
    header('Location:acti.php'); 
    exit(); 
} 

Answer 1

where act_id='".$_REQUEST['upd']."'";
