อยากทราบเกี่ยวกับ sendmail.php คือว่าอยากให้เวลาลูกค้ากรอกข้อมูลสมัครสมาชิกเรียบร้อยแล้วสามารถกด submit

		
		$strSQL = "INSERT INTO member (Username,Password,Name,Email,Status,SID,Active) VALUES ('".$_POST["txtUsername"]."', 
		'".$_POST["txtPassword"]."','".$_POST["txtName"]."','".$_POST["txtEmail"]."','USER','".session_id()."','No')";
		$objQuery = mysql_query($strSQL);
		
		$Uid = mysql_insert_id();
		echo "Register Completed!<br>Please check your email to activate account";		

		$strTo = $_POST["txtEmail"];
		$strSubject = "Activate Member Account";
		$strHeader = "Content-type: text/html; charset=windows-874\n"; // or UTF-8 //
		$strHeader .= "From: [email protected]\nReply-To: [email protected]";
		$strMessage = "";
		$strMessage .= "Welcome : ".$_POST["txtName"]."<br>";
		$strMessage .= "=================================<br>";
		$strMessage .= "Activate account click here.<br>";
		$strMessage .= "https://www.thaicreate.com/activate.php?sid=".session_id()."&uid=".$Uid."<br>";
		$strMessage .= "=================================<br>";
		$strMessage .= "ThaiCreate.Com<br>";

		$flgSend = mail($strTo,$strSubject,$strMessage,$strHeader);
