我有一个登录系统似乎只能使用Firefox登录，我已经尝试在Internet Explorer和Chrome中使用相同的登录详细信息而且它不允许我登录（验证失败！密码不正确，请尝试试。“）
此处在登录页面的代码中：

任何人都知道为什么它似乎只能在Firefox中运行？
答案 0 :(得分：0)
您的代码在哪里检测到登录尝试的POST请求？
通常，当您在检测按钮或提交字段的$ _POST / $ _ REQUEST变量时触发登录过程时会发生这种情况。特别是IE并不总是将其与您表单的其余部分一起发布。
解决此问题的最佳方法是提交隐藏字段以及表单：
<form method = "post" >
<input type = "text" name = "username" value = "1" />
<input type = "password" name = "password" value = "1" />
<input type = "hidden" name = "login_attempt" value = "1" />
<input type = "submit" value = "submit" name = "submit" />
</form>
<?php
if($isset($_POST['login_attempt'])){
$User->login();
}
?>
尝试通过点击输入或点击提交在一些大浏览器中提交这样的表单，唯一不可靠的字段将被提交。
