Question

Codeigniter表单验证不显示错误每当我在codeigniter中提交给定表单中的不完整字段时，它都不会显示任何错误，而是将我重定向到about：blank page 视图：图/ forms.php

<html>
<head>
<title>My Form</title>
</head>
<body>

<?php echo validation_errors(); ?>

<?php echo form_open('form'); ?>

<h5>Username</h5>
<input type="text" name="username" value="" size="50" />

<h5>Password</h5>
<input type="password" name="password" value="" size="50" />

<h5>Password Confirm</h5>
<input type="password" name="passconf" value="" size="50" />

<h5>Email Address</h5>
<input type="email" name="email" value="" size="50" />

<div><input type="submit" value="Submit" /></div>

</form>

</body>
</html>

控制器：

<?php
class Form extends CI_Controller {
  function index()
    {
    /*Load the form validation helpers*/
        $this->load->helper(array('form', 'url'));
    /*Load the form validation helpers*/
        $this->load->library('form_validation');
    /*Set the form validation rules*/
    $this->form_validation->set_rules('username', 'Username', 'required');
    $this->form_validation->set_rules('password', 'Password', 'required');
    $this->form_validation->set_rules('passconf', 'Password Confirmation', 'required');
    $this->form_validation->set_rules('email', 'Email', 'required');
    /*Check if the form passed its validation */
        if ($this->form_validation->run() == FALSE) {
            $this->load->view('forms');
        }
        else {
            $this->load->view('formsuccess');
        }
    }
}
?>

目前我不打算进行数据库验证，只检查是否填写了所有字段，如果是，请转到成功页面或在同一页面上显示验证错误！

Answer 1

尝试在视图中添加required

<input type="text" name="username" value="" size="50" required/>

<h5>Password</h5>
<input type="password" name="password" value="" size="50" required/>

<h5>Password Confirm</h5>
<input type="password" name="passconf" value="" size="50" required/>

<h5>Email Address</h5>
<input type="email" name="email" value="" size="50" required/>

控制器 -

function __construct()
    {
        parent::__construct();

         $this->load->helper(array('form', 'url'));
        $this->load->library('form_validation');

    }

    $this->form_validation->set_rules('username', 'Username', 'trim|required|xss_clean');

检查您的.htaccess文件
