嗨,人们,在下面的代码中,我的会话无法在IE中工作.我不知道为什么对我来说没有错.

browser.php //这里的php在打开页面的浏览器上查找：

session_start();

if ( strpos($_SERVER['HTTP_USER_AGENT'], 'Gecko') )

{

if ( strpos($_SERVER['HTTP_USER_AGENT'], 'Netscape') )

{

$browser = 'Netscape ';

}

else if ( strpos($_SERVER['HTTP_USER_AGENT'], 'Firefox') )

{

$browser = 'Firefox';

}

else if(strpos($_SERVER['HTTP_USER_AGENT'], 'Chrome'))

{

$browser = 'Chrome';

}

else if (strpos($_SERVER['HTTP_USER_AGENT'], 'Safari'))

{

$browser = 'Safari';

}

}

else if ( strpos($_SERVER['HTTP_USER_AGENT'], 'MSIE') )

{

if ( strpos($_SERVER['HTTP_USER_AGENT'], 'Opera') )

{

$browser = 'Opera ';

}

else

{

$browser = 'Explorer';

}

}

else

{

$browser = 'Others browsers';

}

$_SESSION['Ibrowser'] = $browser;

?>

Print.php //由于iFrame,我要在其中打印pdf

session_start();

include("Browser.php");

?>

wk demo

function printTrigger(elementId)

{

var browser = '<?php echo $_SESSION['Ibrowser']; ?>';

var iFramePdf = elementId;

/*alert("hello world");*/

if(browser == "")

{

alert("session is leeg");

}

else

{

if(browser == 'Explorer')

{

//alert("IE");

window.frames[iFramePdf].focus();

window.frames[iFramePdf].print();

}

else if(browser == 'Safari')

{

//alert("Safari");

window.frames[iFramePdf].focus();

window.frames[iFramePdf].print();

}

else if(browser == 'Chrome')

{

//alert("Chrome");

var getMyFrame = document.getElementById(elementId);

getMyFrame.focus();

getMyFrame.contentWindow.print();

}

else if(browser == 'Firefox')

{

//alert("Firefox");

window.open('http://62291.ict-lab.nl/Stage/VDMdm/pdf.php');

}

else

{

alert("Onbekende Browser");

}

}

}

解决方法:

IE在cookie和处理iFrame方面存在问题,原因是P3P (Platform for Privacy Preferences).我发现一个solution是在使用cookie的每个页面中都包含此标头：

header('P3P:CP="IDC DSP COR ADM DEVi TAIi PSA PSD IVAi IVDi CONi HIS OUR IND CNT"');

试试看,让我知道如何进行.
