            $data['captchaImg'] = $captcha['image'];
            $this->load->view('login',$data);
        }
    }

view：login.php

<?php echo form_open(base_url('index.php/')."test/login");?>

    <input type="text" name="fname" id="fname" placeholder="Your First Name" class="text-line"/>

    <input type="text" name="email" id="email" placeholder="Your Email" class="text-line"/>

    <input type="text" name="mobile" id="mobile" placeholder="Your Mobile" class="text-line"/>

    <p id="captImg"><?php echo $captchaImg; ?></p>
    <input type="text" name="captcha" value="" class="captcha" placeholder="Enter Image Inputs"/>
    <a href="javascript:void(0);" class="refreshCaptcha" >Can't Read Please Refersh Image</a>
    <input type="submit" name="signup" id="signup" value="Sign Up" class="btn btn-warning"/>
<?php echo form_close(); ?>

在这段代码中，我创建了一个具有验证码的表单，其中验证码和电子邮件ID已经存在，但是当我将值插入学生表时。表单值将插入到数据库中，但页面不会在登录页面上重定向。现在，我希望在单击“提交”按钮时，它会在表中插入值并显示成功消息。

谢谢

Answer 1

View.login.php

<form method="post" action="<?php echo $_SERVER["PHP_SELF"];?>">

    <input type="text" name="fname" id="fname" placeholder="Your First Name" class="text-line"/>

    <input type="text" name="email" id="email" placeholder="Your Email" class="text-line"/>

    <input type="text" name="mobile" id="mobile" placeholder="Your Mobile" class="text-line"/>

    <p id="captImg"><?php echo $captchaImg; ?></p>
    <input type="text" name="captcha" value="" class="captcha" placeholder="Enter Image Inputs"/>
    <a href="javascript:void(0);" class="refreshCaptcha" >Can't Read Please Refersh Image</a>
    <input type="submit" name="signup" id="signup" value="Sign Up" class="btn btn-warning"/>

</form>

Answer 2

使用

redirect('controllerName/function_name_where_you_want_to_redirect');

如果在仅包含

的控制器中创建单独的index（）函数会更好

$this->load->view('view_name');

然后重定向到已经提到的那个功能。

希望有所帮助

Answer 3

要在提交表单后重定向到同一页面，您不需要在 form_open（）函数中传递任何参数。

提交时，页面在同一页面上不重定向？
