Question

Hello i am new to PDO so getting confused and getting errors 😉 with mysql_real_escape_string ..

can any one help, here is my code

if(!empty($_POST) && isset($_POST)) { 

include ('connection_pdo.php');

$dbh = new PDO("mysql:host=$host;dbname=$dbname", $user, $pass);

$source_url= mysql_real_escape_string($_POST['source_url']);
$class     = mysql_real_escape_string($_POST['class']);
$year      = mysql_real_escape_string($_POST['year']);
$date      = time();
$ip        = $_SERVER['REMOTE_ADDR'];

$insert = $dbh->prepare("
  INSERT IGNORE INTO school_students_images
            ( folder_name,  image_url,  source_url,  class, year , date , ip )
    VALUES  (:folder_name, :image_url, :source_url, :class, :year, :date, :ip)
");

$a=0;
while ($a<1000){
$a++;
$insert->execute(array(
            'folder_name'=> $name->content, //** geting from other source
            'image_url'  => $link[$a], //** geting from other source
            'source_url' => $source_url,
            'class'      => $class ,
            'year'       => $year ,
            'date'       => $date,
            'ip'         => $ip
            ));
}

it not working getting error but if i am using it with-out

    $source_url= ($_POST['source_url']);
    $class     = ($_POST['class']);
    $year      = ($_POST['year']);
    $date      = time();
    $ip        = $_SERVER['REMOTE_ADDR'];

it is working … so i am confused is it safe to POST without mysql_real_escape_string into database? (is PDO giving any security by default ?) or i am doing some mistake in this…
please help

Yes, PDO automatically escapes your data, so you don’t need to use mysql_real_escape_string. See here, for example.
