Question

我是PHP新手。你能在登录后帮我重定向吗？

登录后重定向转到 /user_menu.php 。我想要一样：如果我从页面 /browse.php?id=198 （它是类别链接）登录，登录后我重定向到同一页面，而不是user_menu.php。

很抱歉有一个dublicate问题。我只是想和你分享我的代码。感谢您的帮助：）

登录表单

<form class="form"  name="login" action="{SSLURL}user_login.php" method="post" id="login-nav">
    <div class="form-group">
        <label class="sr-only" for="exampleInputEmail2">{L_003}</label>
        <input class="form-control" type="text" name="username" id="username" placeholder="{L_003}">
    </div>
    <div class="form-group">
        <label class="sr-only" for="exampleInputPassword2">{L_004}</label>
        <input type="password" name="password" id="password" class="form-control" placeholder="{L_004}">
        <div class="help-block text-right"><a href="{SITEURL}forgotpasswd.php">{L_215}</a></div>
    </div>
    <div class="form-group">
        <button type="submit" name="action" class="btn btn-primary btn-block">{L_275}</button>
    </div>
    <div class="checkbox">
        <label>
            <input for="rememberme" type="checkbox"> {L_25_0085}
        </label>
    </div>
</form>

要在登录后立即重定向到其他页面，只需使用重定向：

header('Location: http://www.yoursite.com/whatever-page.php'); exit();

编辑：

抱歉，我错了。你想回到你登录的任何页面，对吧？

我建议点击设置一个cookie。如果您正在使用jquery，当用户提交登录表单时，您可以使用当前网址保存cookie。

然后在登录后，使用php读取该cookie并重定向用户（或者您也可以使用jquery重定向）。
