güvenlik kodu doğruysa dosyayı otomatikmen indirmesini istiyorum. kodlar şöyle.
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=windows-1254">
<script language="JavaScript" type="text/javascript" src="ajax_captcha.js"></script>
</head>
<body>
<form action="javascript:get(document.getElementById('myform'));" name="myform" id="myform">
<p align="center">
<img id="imgCaptcha" src="create_image.php" onclick="setTimeout('refreshimg()', 300); return false;" alt="Degistir"/>
<input id="txtCaptcha" type="text" name="txtCaptcha" value="" maxlength="10" size="10" autocomplete="off"/>

http_request.send(null);
}

function refreshimg()

//Change the image
img.src = 'create_image.php?' + Math.random();
}buda php kodu<?php
session_start();
$id = $_GET[link_id];
if ( ($_GET["txtCaptcha"] == $_SESSION["security_code"]) && (!empty($_GET["txtCaptcha"]) && !empty($_SESSION["security_code"])) ) {
header('Refresh: 10; url=1.zip');
} else {
echo '<font face="Verdana" size="1" color="#FF0000">Guvenlik Kodunu Yanlis Girdiniz.Lutfen Tekrar Deneyiniz</font>';
}
?>kod doğruysa dosyanın otomatik inmesini istiyorum. ajax ile ne yönlenme çalışıyor nede header attachment kodu. girilen güvenli kod doğru ise aşağıdaki kodları çalışırmak istiyorum fakat ajaxta çalışmıyor?
header('Content-Type: application/zip);
header('Content-Disposition: attachment; filename="1.zip"');
header("Content-Type: application/download");
yardım ederseniz sevinirim..
