Thanks too http://stackoverflow.com/a/7851347/1133011 for the help
on layout which acts more like frames but avoids them and using divs. As frames have
known draw backs see here http://stackoverflow.com/questions/4600648/frames-with-php we
should thus rather use include in php

我看到了警报，但像以前一样被重定向到一个空白html（甚至比以前还要多，至少表单被重新加载了）听起来您可能想首先评估索引页面中的所有数据，然后通过将内部php设置为相同的索引页面，并将get查询更新为您想要的任何内容来执行页面重定向
header("Location: http://www.example.com/index.php?page=profile");
exit();
在执行重定向之前，请确保不使用echo或任何其他方式输出任何html。如果您的脚本之前大量使用echo，则可以查看echo。PHP是服务器端语言，不是动态的。您希望使用javascript（在我的示例中为jQuery）
$\u GET=；
如果（$\u GET['val']==某个值）{
$.get（index.php？getvar=getval{
完成：函数（）{
$（'#div'）.val（“您的输出”）；//*
}
});
}
*这可以是您喜欢的任何代码，如果您选择php是服务器端的，那么您可以用整个php文件替换div，因此无法执行您试图执行的操作。请尝试jquery.ajax（）您想使用jQuery进行此操作。@HydraIO+1感谢更新的问题…我如何通过jQuery>Load使用HTTP GET请求从服务器加载数据来实现这一点..GET（）将立即发送GET请求。感谢查看这个带有注释头的更新代码示例…这给了我错误，但我认为这是因为回音thing@DavidKroukamp：检查输出缓冲如果在执行重定向之前使用了大量回显，请查看my login.php代码和注释标题在if语句中…它给出错误警告：无法修改头信息-头已由发送（输出从C:\Program Files（x86）\Apache Software Foundation\Apache2.2\htdocs\login.php:22开始）@DavidKroukamp：在第1行之后关闭php并输出html。在这之前打开输出缓冲。然后在脚本末尾显示缓冲区中的内容。@DavidKroukamp:要理解吗
header("Location: http://www.example.com/index.php?page=profile");
exit();
$_GET = <?php echo json_encode($_GET); ?>;
if($_GET['val'] == some_value){
$.get(index.php?getvar=getval, {
complete: function(){
$('#div').val("YOUR OUTPUT"); // *
}
});
}
