Php 验证注册表中的数据后,重定向到另一个页面以登录
我不熟悉php和mysql。我正在尝试创建一个用户注册表单,验证数据,然后重定向到一个登录页面,在那里他们可以输入用户名和密码进行登录。我已经编写了代码,但由于某些原因,我无法正确使用header()。 以下是我目前的代码:Php 验证注册表中的数据后,重定向到另一个页面以登录,php,html,mysql,forms,post,Php,Html,Mysql,Forms,Post,我不熟悉php和mysql。我正在尝试创建一个用户注册表单,验证数据,然后重定向到一个登录页面,在那里他们可以输入用户名和密码进行登录。我已经编写了代码,但由于某些原因,我无法正确使用header()。 以下是我目前的代码: $userErr= $passErr= $passErrc= $firstErr= $lastErr= $middle= $addErr= $cityErr= $stateErr=$zipErr= $emailErr= $phoneErr= $passMatchE

控件转移到另一页后,必须退出代码段。否则将执行以下代码。因此,请使用exit;
after header()
我可能是错的,但从if/else语句的结构来看,似乎只有在请求方法不是POST时才会发送头(即,看起来像是在else部分)。我认为它位于错误的位置
我认为需要删除的就是这个(尽管我不确定您的验证如何使用当前代码停止重定向)
{$phone=test_输入($_POST[“phone”]);}
}
其他的
{
如果($password!=$pass\u conf){
尝试在文件顶部使用ob_start();在文件底部使用ob_end_flush()。好的,您说过数据正常进入数据库,但标头()无法重定向。
发生这种情况的唯一方法是在header()发生之前回显一些字符
确保在页眉()之前未打印任何内容。
确保页面开头没有BOM元素。
只需删除主if语句的else部分和主if语句中的密码确认部分:

错误是-只有当
请求的方法不等于POST
因此,如果请求方法是POST,则执行上面的代码&输入的密码与确认密码匹配,然后将用户重定向到登录页面。现在就可以了!将标题(“Location:login.html”);放入if($\u SERVER[“request\u method”]=“POST”)而不是此if语句的其他部分。位置后空格:可能?我尝试过,数据被插入到数据库中,但它仍然没有指向我的登录页。它会一直显示注册文件号。但是在头命令之前的任何输出都会显示。请检查是否没有空格
