Php Codeigniter一页多表，单独验证

php forms codeigniter

Php Codeigniter一页多表，单独验证,php,forms,codeigniter,Php,Forms,Codeigniter,我一页有两张表格。当我点击表单一的提交按钮时，两个表单上都会显示验证错误。如何在每个表单上显示单独的验证错误 我的看法是： <?php echo form_open('user_signup/login',['class'=>'login-form','id'=>'submit_form']); echo validation_errors();?> <h3 class="form-title font-green">

我一页有两张表格。当我点击表单一的提交按钮时，两个表单上都会显示验证错误。如何在每个表单上显示单独的验证错误

我的看法是：

        echo validation_errors();?>
            <h3 class="form-title font-green">Sign In</h3>

这是我的控制器：

<?php
defined('BASEPATH') OR exit('No direct script access allowed');

class User_signup extends CI_Controller {
public function index()
{
    $this->load->view('User/signup');
}

    public function login()
{
     if ($this->input->post('submit_form')) {
  $rules['email1'] = 'required';
  $rules['pass'] = 'required';
  $this->form_validation->set_rules($rules);
}
else if ($this->input->post('register_form')) {
  $rules['rollno'] = 'required';
  $rules['email2'] = 'required';

  $this->validation->set_rules($rules);
}

if (!$this->form_validation->run()) {
  $this->load->view('User/signup');
}
else {
  if ($this->input->post('submit_form'))
      echo 'Form 1 posted !';
  else if ($this->input->post('register_form'))
      echo 'Form 2 posted !';
}
}
}

<?php
defined('BASEPATH') OR exit('No direct script access allowed');

class User_signup extends CI_Controller {
public function index()
{
    $this->load->view('User/signup');
}

public function login()
{
    // Checking passed 3rd parameter in URI string.
    $submitted_form = $this->uri->segment(3)?$this->uri->segment(3):false;
    if ($submitted_form == 'form-1') {
        $rules['email1'] = 'required';
        $rules['pass'] = 'required';
        $this->form_validation->set_rules($rules);
    }
    if ($submitted_form == 'form-2') {
        $rules['rollno'] = 'required';
        $rules['email2'] = 'required';
        $this->validation->set_rules($rules);
    }

    if ($this->form_validation->run()) {
        if ($submitted_form == 'form-1')
            echo 'Form 1 posted !';
        else if ($submitted_form == 'form-1')
            echo 'Form 2 posted !';
    }
    $this->load->view('User/signup');
}
}
通过Jquery提交。比如在你看来

<form id="form1" action="" method="post">
  <label>Username</label>
  <input type="text" name="username">
  <label>Password</label>
  <input type="password" name="password">
  <input type="hidden" name="form_type" value="login">
  <button type="submit" onClick="login()">Login</button>
</form>
<form id="form2" action="" method="post">
  <label>Username</label>
  <input type="text" name="username">
  <label>Password</label>
  <input type="password" name="password">
  <label>Email</label>
  <input type="email" name="email">
  <input type="hidden" name="form_type" value="register">
  <button type="submit" onClick="register()">Login</button>
</form>
有两件事你需要关注。HTML表单中的第一个传递操作。其次，在控制器的操作中获得相应的参数和代码

<?php echo form_open('user_signup/login/form-1',['class'=>'login-form','id'=>'submit_form']);
echo validation_errors();?>
<h3 class="form-title font-green">Sign In</h3>
<div class="alert alert-danger display-hide">
    <button class="close" data-close="alert"></button>
    <span> Enter any username and password. </span>
</div>
<div class="form-group">
    <!--ie8, ie9 does not support html5 placeholder, so we just show field title for that-->
    <label class="control-label visible-ie8 visible-ie9">Email</label>
    <?php echo form_input(['name'=>'email1','type'=>'text','style'=>'text-transform: capitalize;','class'=>'form-control form-control-solid placeholder-no-fix','autocomplete'=>'off','placeholder'=>'Email','value'=>set_value('email1')]); ?>
</div>
<div class="form-group">
    <label class="control-label visible-ie8 visible-ie9">Password</label>
    <?php echo form_input(['name'=>'pass','type'=>'password','class'=>'form-control form-control-solid placeholder-no-fix','autocomplete'=>'off','placeholder'=>'Password']); ?>
</div>
<div class="form-actions">
    <?php echo form_submit('submit', 'Submit',"class='btn green uppercase'" ); ?>


    <a href="javascript:;" id="forget-password" class="forget-password">Forgot Password?</a>
</div>
<div class="login-options">
    <h4>Or login with</h4>
    <ul class="social-icons">
        <li>
            <a class="social-icon-color facebook" data-original-title="facebook" href="javascript:;"></a>

<!-- END LOGIN FORM -->

            <?php echo form_submit('register', 'register',"class='btn btn-success uppercase pull-right'" ); ?>
注意：检查表单操作

这是您更新的控制器：

<?php
defined('BASEPATH') OR exit('No direct script access allowed');

class User_signup extends CI_Controller {
public function index()
{
    $this->load->view('User/signup');
}

    public function login()
{
     if ($this->input->post('submit_form')) {
  $rules['email1'] = 'required';
  $rules['pass'] = 'required';
  $this->form_validation->set_rules($rules);
}
else if ($this->input->post('register_form')) {
  $rules['rollno'] = 'required';
  $rules['email2'] = 'required';

  $this->validation->set_rules($rules);
}

if (!$this->form_validation->run()) {
  $this->load->view('User/signup');
}
else {
  if ($this->input->post('submit_form'))
      echo 'Form 1 posted !';
  else if ($this->input->post('register_form'))
      echo 'Form 2 posted !';
}
}
}

<?php
defined('BASEPATH') OR exit('No direct script access allowed');

class User_signup extends CI_Controller {
public function index()
{
    $this->load->view('User/signup');
}

public function login()
{
    // Checking passed 3rd parameter in URI string.
    $submitted_form = $this->uri->segment(3)?$this->uri->segment(3):false;
    if ($submitted_form == 'form-1') {
        $rules['email1'] = 'required';
        $rules['pass'] = 'required';
        $this->form_validation->set_rules($rules);
    }
    if ($submitted_form == 'form-2') {
        $rules['rollno'] = 'required';
        $rules['email2'] = 'required';
        $this->validation->set_rules($rules);
    }

    if ($this->form_validation->run()) {
        if ($submitted_form == 'form-1')
            echo 'Form 1 posted !';
        else if ($submitted_form == 'form-1')
            echo 'Form 2 posted !';
    }
    $this->load->view('User/signup');
}
}
