Hi? Thanks to Vinay for your help? works very good... But I can?t validate if one or more of the emails insert in the textarea exist in the table of the DB to not insert it, but yes insert the others mails that not exist in the db. This the cod: <html> <head> <title>Explode trial</title></head> <body> <?php if($_GET['emailreader']) { $username="root"; $password="root"; $database="anda"; $con = mysql_connect("localhost",$username,$password); mysql_select_db("$database", $con); $str = $_GET['emailreader']; $text=$_GET['emailreader']; $spacecount=substr_count($text," "); $emails_exploded=(explode(" ",$str)); $sql = "SELECT * FROM mailing"; $result = mysql_query($sql); $array = mysql_fetch_array($result); $mail = $array['mail']; for ($i=0;$i<=$spacecount;$i++) { if($emails_exploded[$i] != $mail) { echo $emails_exploded[$i]; mysql_query("INSERT INTO mailing (mail) VALUES('$emails_exploded[$i]')") or die(mysql_error()); } } } ?> <form action="<?php $_SERVER['PHP_SELF'] ?>" method="get" name="emailform"> <label for=email>Email</label> <input type="text" name="emailreader" size="200" /> <input type="submit" name="submit" value="Ok !" /> <input type="hidden" name="trigger" value="6" /> <input type="reset" name="cancel" value="Cancel" /> </form> </body> </html> Thanks a lot + _ // Emiliano Boragina _ // Diseño & Comunicación ////////////////// + _ // emiliano.boragina@xxxxxxxxx / // 15 40 58 60 02 /////////////////////////// + _
