Php 使用CodeIgniter框架登录后重定向到其他页面

我创建了一个登录控制器，当我重定向到我的站点主页时，它不会重定向到我的视图（即索引）

这是我的控制器（main.php）：

试试这个

在视图中

<input name="username" type="text" class="form-control" placeholder="User ID" autofocus value="<?php echo set_value('username'); ?>" >
<br>
<input name="password" type="password" class="form-control" placeholder="Password"  value = "<?php echo set_value('password'); ?>">

在型号中

public function validate () {
    $this->db->where('admin_username', $this->input->post('username'));
    $this->db->where("admin_pword", md5($this->input->post("password")));
    $query = $this->db->get("administration");
    $result = $query->result_array();
    $count = count($result);

    return $count;

}

表单中缺少名称属性

<input name="username" type="text" class="form-control" placeholder="User ID" autofocus value="<?php echo set_value('username'); ?>" >
       ^             ^
<input name="password" type="password" class="form-control" placeholder="Password"  value = "<?php echo set_value('password'); ?>">
       ^             ^

您忘记在
login\u view.php

将您的
查看代码
替换为以下内容

<form class="form-login" method="post" name="redirect" action="<?php echo site_url("main/validate_credentials"); ?>">
        <h2 class="form-login-heading">sign in now</h2>
        <div class="login-wrap">
            <input name="username" type="text" class="form-control" placeholder="User ID" autofocus value="<?php echo set_value('username'); ?>" >
            <br>
            <input name="password" type="password" class="form-control" placeholder="Password"  value = "<?php echo set_value('password'); ?>">
            <label class="checkbox">
                <span class="pull-right">
                    <a data-toggle="modal" href="login.php#myModal"> Forgot Password?</a>

                </span>
            </label>
            <button class="btn btn-theme btn-block" name="login" type="submit"><i class="fa fa-lock"></i> SIGN IN</button>
         </div>

         <?php  $this->load->view("modals/forgot_pass_modal"); ?>

 </form>

由于您的问题只是关于重定向，请遵循以下步骤

redirect('Main/homepage1', 'refresh');

作为

当您重定向到新链接时，不需要刷新它。
希望有帮助
您能给我们看一下重定向的routes.php条目（'Main/homepage1'）？它将帮助任何人理解。这里：$route['default\u controller']=“Main”$路由['404_覆盖']=''；Main/homepage1的路由在哪里？在我目前使用的版本中，route.php中只有两个变量。我正在使用2.1.4测试这一点，
redirect（'main/homepage1'）public function validate () {
    $this->db->where('admin_username', $this->input->post('username'));
    $this->db->where("admin_pword", md5($this->input->post("password")));
    $query = $this->db->get("administration");
    $result = $query->result_array();
    $count = count($result);

    return $count;

}

       ^             ^
